READ THIS FIRST WARNING The Alarm should be permanently wired to the mains by a qualified electrician in accordance with IEE wiring regulations (BS7671 Install the Carbon Monoxide Alarm (CO Alarm) in every room that contains a fuel burning appliance, particularly rooms where people spend a lot of time e.g. bedrooms, kitchens and sitting rooms. In rooms with an appliance install (perferably) on the ceiling (300mm from walls) and between 1m to 3m horizontally from appliance. In rooms remote from the appliance install at breath level, where the light indicators can be seen. Regularly check that the green power light is on, so that standby rechargeable cells will fully charge. Important: The CO Alarm will not work if the mains supply is off and the rechargeable cells are depleted. Test the unit weekly by pressing the test/hush button-the horn will sound. Replace sensor module after 5 years operation (see page 20). 1

****** Page 4 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 4 What to do when the alarm sounds: (1) Open the doors and windows to ventilate the area. (2) Turn off all fuel appliances where possible and stop them. (The alarm can be silenced immediately by pushing the test/hush button). (3) Evacuate the property leaving the doors and windows open. (4) Get medical help immediately for anyone suffering the effects of Carbon Monoxide poi- soning (headache, nausea), and advise that Carbon Monoxide poisoning is suspected. (5) Ring your gas or other fuel supplier on their emergency number. Keep the number in a prominent place. (6) Do not re-enter the property until the alarm has stopped. (If the alarm has been silenced by pressing the test/hush button, wait at least 5 minutes so the alarm can check that the CO has cleared). (7) Do not use the fuel appliances again until they have been checked by an expert. In the case of gas appliances this must be a CORGI registered installer. When the CO Alarm detects abnormal levels of CO (above 50ppm CO) the red light starts to flash and the horn will sound within 90 minutes. At higher levels of CO the alarm will turn on sooner (see table B – page 6). 2

****** Page 5 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 5 IVI The CO Alarm will automatically reset once the CO has cleared. Pressing the test/hush button resets the CO Alarm immediately (below 300ppm CO). If CO is still present the red light and horn will turn on again after about 4 minutes. The CO Alarm is no substitute for keep- ing chimneys and flues clear and in good condition, and all of your appli- ances serviced regularly according to the manufacturer’s instructions. Do not fit alarm until all building work is completed to avoid contamination. 2. CARBON MONOXIDE – THE SILENT KILLER!

PUSH COVER BACK 2.1 What is Carbon Monoxide ? Congratulations on becoming the owner of an Ei Carbon Monoxide Alarm. This will help protect you and your household from the dangerous effects of Carbon Monoxide – the silent killer. (CO is the chemical symbol, indi- cating the module has one carbon atom and one oxygen atom). WARNING: DISCONNECT MAINS BEFORE REMOVING ALARM FROM CEILING OR WALL 3

****** Page 6 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 6 Many are killed each year, and many more suffer ill health from Carbon Monoxide (CO) poisoning. CO is an invisible, odourless, tasteless and extremely toxic gas. It is produced by appliances and vehicles burn- ing fuels, such as coal, oil, natural/bottled gas, paraffin, wood, petrol, diesel, charcoal etc. CO is absorbed by red blood cells in the lungs in preference to oxygen this results in rapid damage to the heart and brain from oxygen starvation. High levels of CO in a house can be caused by: • Incorrectly or poorly installed fuel-burning appliances. • Blocked or cracked chimneys/flues. • Blocked vents or draught-proofing which makes areas with fuel burning appliances or fireplaces airtight. • Engines of cars, lawnmowers etc. left running in confined spaces. • Portable paraffin or gas heaters in badly ventilated rooms. 2.2 Symptoms of Carbon Monoxide Poisoning Most people know that high levels of CO are harmful, however the period of exposure is also important. The following symptoms are related to Carbon Monoxide poisoning and should be discussed with all members of the household. Mild Exposure: Slight headache, nausea, vomiting, fatigue (often described as “flu-like” symptoms). Medium Exposure: Severe throbbing headache, drowsiness, confusion, fast heart rate. Extreme Exposure: Unconsciousness, convulsions, cardiorespiratory failure, death. 4

****** Page 7 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 7 A high level of CO for a short period (e.g. 350 ppm CO for 30 minutes) will cause the same symptoms, a slight headache, as a lower level for a longer time (e.g. 150 ppm for 90 minutes). Table A shows how exposure to different concentrations of CO generally affects people. Many cases of reported Carbon Monoxide poisoning indicate that while victims are aware they are not well, they become so disorientated they are unable to save themselves by either leaving the building or calling for assistance. Young children and household pets may be the first affected.

When the Alarm detects potentally dangerous levels of CO, it flashes the red alarm light and then sounds a loud alarm if the CO persists. The digital display indicates the CO level in parts per million, ppm CO, (Model Ei261 DEN only). Table B below shows how the CO Alarm reacts to different levels of CO gas and exposure time. At higher levels of CO the alarm turns on sooner. The rate of flashing of the red light indicates the level of CO. Table B: CO Alarm Response CO Level ppm O ppm 50ppm 100 ppm 300 ppm Red Alarm Light Off * 1 Flash / 2 Seconds 2 Flashes / Second 4 Flashes / Second Horn On within Off 60 to 90 minutes 10 to 40 minutes 3 minutes unless it has been in alarm (see CO Alarm Memory below) If your CO Alarm sounds follow the instructions on page 2. When ventilation is provided by leaving the window and doors open, the CO build up may have dissipated by the time help arrives and the alarm may have stopped sounding. Although your problem may appear temporarily solved it is crucial that the source of the CO is determined and appropriate repairs made. 6

****** Page 9 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 9 NEVER IGNORE THE ALARM. Pre-Alarm: When the alarm detects over 50ppm CO the red light flashes every 2 seconds. This helps locate CO leaks as the unit gives an indication straight away. (Without this feature the CO level would need to be at 50ppm CO for 90 minutes for an indication to be given). Note the Pre-Alarm signal may be triggered by CO coming for example, from cooking with gas, from car engines or from nearby barbecues. This is usually not a concern unless the Pre-Alarm signal persists until the alarm sounds and the CO source is unknown. NOTE: The CO Alarm may sound if cigarette smoke is blown into it, or aerosols are released nearby. CO ALARM MEMORY. When the test button is pressed the horn will sound, and the red light will only flash if the unit has previously detected CO and been in alarm. The flash rate indicates the level of CO detected as below:- Red light is Off — No CO detected since reset or power up. Red light flashes 2 times (in 2 seconds) every 40 seconds, 50 ppm CO detected for about 90 minutes since reset or power-up. Red light flashes 4 times (in 2 seconds) every 40 seconds, 100 ppm CO detected for about 40 minutes since reset or power-up. Red light flashes 8 times (in 2 seconds) every 40 seconds, 300 ppm CO detected for about 3 minutes. Reset Memory by holding down the test button for over 20 seconds until the red light stops flashing. Cover the horn with a cloth to muffle the alarm during this time. 8261 -DEN only When the test button is held the display shows the previous peak reading. This tells you if the unit has detected CO in your absence and helps to detect and locate leaks, monitor premises etc. 7

****** Page 10 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 10 When the test button is held for 20 seconds the peak reading resets to zero. (Cover the horn with a cloth to muffle the loud alarm). Please note that the memory will also be reset when the unit is removed from the mounting plate. 3. WHERETO PLACE CO ALARMS 3.1 Ideally a Carbon Monoxide Alarm should be installed in: – Every room containing a fuel burning appliance, and – Remote rooms where occupants spend a considerable amount of time – Every bedroom. However if the number of Carbon Monoxide Alarms is limited the following points should be considered when deciding where best to fit the alarm(s) If there is an appliance in a room where people sleep, place a CO Alarm in this room and – Locate a CO alarm in a room containing a flueless or open-flued appliance, and – Locate an alarm in a room where the occupant(s) spend most of their time (e.g. sitting room) and – In a bedsit, the CO alarm should be placed as far away from the cooking appliance as possible, but near to where the person sleeps and If the appliance is in a room not normally used, such as a boiler room, the CO alarm should be placed just outside the room so that the alarm will be heard more easily. 8

****** Page 11 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 11 3.2 Unsuitable Locations Do not place the CO Alarm in any of the following areas. (2) (3) (4) (5) (6) (7) (8) (9) (10) (11) (12) (13) In the immediate vicinity of a cooking appliance (keep it at least 1 metre horizontally from it). Outside the building. In an enclosed space (e.g. in or below a cupboard). In a damp or humid area. Directly above a sink or cooker. Next to a door, window, air vent or anywhere that it would be affected by draughts. Next to an extractor fan. Where it would be obstructed, e.g. by curtains or furniture. In an area where the temperature could drop below —1 OOC or rise above 400C. Where dirt or dust could block the sensor. Where it could be easily knocked or damaged, or where it could be accidentally turned off or removed. In a bathroom or other areas where the CO alarm may be exposed to water splashes, dripping or condensation (e.g. above an electric kettle). Near paint, thinners, solvent fumes or air fresheners. 9

****** Page 12 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 12 3.3 If locating the CO alarm in a room with a fuel burning appliance (see figure 2) • If it is mounted on a wall, it should be located at a height greater than the height of any door or window but still be at least 150mm from the ceiling. • If it is mounted on the ceiling it should be at least 300mm from any wall or light fitting. • The CO alarm should be a horizontal distance of between 1m and 3m from the potential CO source. • If there is a partition in the room, the CO alarm should be located on the same side of the partition as the potential source. • In rooms with sloped ceilings, the CO alarm should be located at the high side of the room (see fig 3). 3.32 If locating the CO alarm in a bedroom or in rooms remote from a fuel burning appliance (see figure 4) • Mount the CO alarm relatively close to the breathing zone of the occupants. Whatever position is chosen make sure it is possible to view the three light indicators, when in the vicinity of the alarm. 10

INSTALLING YOUR CARBON MONOXIDE ALARMS The Alarm is designed to be permanently mounted, using its own built-in terminal block to connect it to the mains. The mounting plate can be screwed directly to the ceiling. Alternatively it can be screwed to a standard junction box (BS 4662 single gang accessory box). It requires a current of 60mA. The Alarm must not be exposed to dripping or splashing. There are important markings on the underside of the alarm. IMPORTANT PRECAUTION: Do not install the actual alarm itself in new or renovated buildings until all work is completed (including floor coverings) and the building has been fully cleaned. The wiring can be installed when appropriate. (Excessive dust and debris from building work can con- taminate the sensor and cause problems, it will also invalidate the guarantee). If it must be installed, cover it completely, particularly around the edges, with a dust cover, until all cleaning is finished. The Alarm must not be connected when the house wiring insulation is being checked with high voltages i.e. don’t use an insulation tester on the alarm. WARNING: Do not use the CO Alarm on an intermittent basis, or as a portable detector for the spillage of combustion products from fuel burning appliances or chimneys. WARNING: Mains operated Alarms should be installed and interconnected by a qualified electrician in accordance with the Regulations for Electrical Installations published by the Institution of Electrical Engineers (UK). Failure to install this Alarm correctly may expose the user to shock or fire hazards. WARNING: The Alarm must be continuously powered 24 hours a day so it is important that it is not on a circuit that can be turned off by a switch. 13

****** Page 16 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 16 INSTALLATION PROCEDURE (1) Select a location complying with the above advice. (2) Disconnect the AC mains supply from the circuit that is going to be used. (3) The house wiring must be connected to the terminal block on the mounting plate as follows: L: Live – connect to the house wires coloured brown or marked L. N: Neutral – connect to the house wires coloured blue or marked N. IC: Interconnect – If you are only installing one alarm do not connect any cable to the IC terminal. See below for information on interconnecting. Warning: Mixing Live & Neutral wires will damage interconnected alarms. Do not use an earth wire for the interconnect line. Use a suitably coloured core, with the ends marked if necessary, for the interconnect that will not be confused with the live or neurtal cores. (4) Lift off the wiring cover as shown in Figure 5. N.B. The Alarm does not need to be earthed. However the terminal marked (9 is provided for the con- venience of the installer so that any copper earth wire or cable coloured green-or green & yellow, can be safely terminated. (5) If the mains wires are being brought along the surface, conduit can be inserted into the top and/or bottom, for the cable. (a) position the mounting plate, so that the cable conduit is as shown in Figure 5. (b) Carefully cut around the knockout on the outside wall so the conduit fits. (Note: to comply with the BS EN 60529, IPX2D protection rating, seal around conduit with silicone rubber or similar to prevent water entering). (6) If the mains wires are recessed, bring the wires through the rear hole in the mounting plate as shown 14

WIRING CONDUIT KNOCK OUT FOR SURFACE WIRING CONDUIT MAINS WIRING RECESSED WIRING AREA L- LIVE N – NEUTRAL IC – INTERCONNECT O EARTH (IF PRESENT) (7) Carefully align the mounting plate and screw into place. Connect the wires to the terminal block. With recessed wiring, ensure the rear gasket seals around the edge of the hole in the ceiling or wall. This is to prevent air draughts affecting the CO gas entering the alarm. If the orifice is not closed off by the gas- ket it should be sealed with silicone rubber or equivalent. Replace the wiring cover. 15

****** Page 18 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 18 Carefully line up the unit on the base and slide on. Press the test/hush button for 10 seconds. The horn will sound. CAUTION: Do not attempt to remove the Alarm without first releasing the tamper clip as shown in Figure 1. (8) Connect the mains power to the alarm circuit. Check the green light is on. The CO Alarm is now fully operational and will provide protection against a build up of Carbon Monoxide gas, 70 seconds after it is connected to the mains supply. (9) The unit may be tamperproofed further, by removing the knockout in the sidewall of the mounting plate as shown in Figure 1. Insert the self tapping screw (3mm diameter, 12mm long) after the unit is on the mounting plate. INTERCONNECTING Ei ELECTRONICS CARBON MONOXIDE ALARMS With interconnected alarms, when one unit detects CO all units alarm. All horns will sound but only units detecting CO will flash their red lights. A maximum of twelve Ei 261 EN/261 DEN CO Alarms may be interconnected along with an Ei 128C module with relay (see technical specifications). WARNING: Do not connect these Alarms to any other type of Ei Alarm, or to any other model produced by another manufacturer, apart from those listed above. Doing this may damage the Alarms and could result in a shock or fire hazard. The interconnect wire (minimum 0.75mm2 cable) must be treated as if it was live. It should be insulated and sheathed. A maximum of 250 metres (820 ft) of wire can be used (maximum resistance between detectors 50 16

****** Page 19 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 19 Figure 7 – Interconnect Wiring Diagram – INTERCONNECT N – NEUTRAL L- LIVE ohms). Connect as shown in Figure 7. L N These Carbon Monoxide Alarms should be interconnected only within the confines of a single family living unit. If they are connected between different units there may be excessive nuisance alarms. Everybody may not be aware that they are being tested etc. CO ALARMS AND SMOKE ALARMS SHOULD NOT BE INTERCONNECTED! This is because the actions to take in each situation are very different. In the case of CO the premises should be fully ventilated by opening doors and windows. The user should call his gas supplier etc. In the case of fire ,doors and windows should be closed, to slow the spread of fire. The user should call the fire brigade etc. 17

****** Page 20 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 20 5. TESTING YOUR CO ALARM (1) Regularly check that the green mains power light is on. The unit cannot detect CO if the mains power is not on and the rechargeable battery is depleted. (If it is off check circuit breakers, fuses, wiring etc). (2) Test the unit weekly by pressing the test/hush button. Hold the test button (for up to 10 seconds) until the horn sounds for over 5 seconds. This will help to familiarise you and your family with the distinctive on-off sound of the CO Alarm. This test checks that the electronics and horn are working correctly. If the units are interconnected, button test each unit in turn and check all interconnected units alarm. (If the red alarm light flashes when the button is pressed (see CO Alarm Memory section 2.3 above). (3) If the CO Alarm gives a short beep and the amber fault light flashes every 40 seconds it means the self-checking circuit has detected a fault. Press and hold the test/hush button. If the amber light flashes without the horn sounding, the sensor is faulty. On the Ei 261 DEN the display will show SF indicating Sensor Faulty. (4) If the Alarm fails to operate when the test/hush button is pressed, disconnect the mains supply at the distribution fuse board, remove unit from mounting plate for 3 minutes. Put unit back on mounting plate. Re-connect the mains and try again. (This procedure resets the microprocessor in the unit). (5) If the unit beeps every 40 seconds (without a light flash) it means the battery is depleted. (On the Ei 261 DEN with depleted cells, the display will show CP to remind you to Connect mains Power). Connect mains (ensure green light is on) to allow cells to charge. (6) Once a year check the rechargeable cells by switching off mains and pressing the test button for 10 seconds. The horn should sound loudly Re-connect mains power. If the CO Alarm fails any of the above tests it must be replaced immediately (see section 10 “Getting the CO Alarm Serviced”). 18

****** Page 21 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 21 Testing with Carbon Monoxide The unit checks for CO every 4 seconds and as soon as it detects CO it flashes the red light (as per Table B) to confirm that is detecting CO gas. Alternatively: Pressing the test button causes the unit to check for CO – this is the Fast CO Test Mode. This eliminates the long wait normally required e.g. up to 90 minutes at 55ppm CO and up to 3 minutes at 330ppm CO. The unit can be tested with CO by using one of the kits that comes with CO either in a glass phial or aerosol can. Follow the instructions on the kit but be sure to press the test button to speed up the CO sampling directly after you expose the unit to the CO. It is best if possible to inject the CO gas into the gas entry holes, see Figure 1. When it senses the CO it will give 3 beeps and the red light will flash as per table B. It then resets to normal mode. (If unit fails to respond press test button again as gas can take some seconds to enter sensor). The Fast CO Test Mode normally does not activate the memory function unless a high level of CO remains in the sensor for a few minutes. (This can be checked by pressing the test button. If the red light flashes continuously indicating CO was detected, hold the test button for 20 seconds until the red light stops flashing as the memory resets). How to distinguish between CO Alarm and Smoke Alarm Warnings The CO Alarm has a distinctive on-off sound of 3 pulses, followed by a pause as compared with a typi- cal Smoke Alarm which has a rapid pulsing sound. In addition, when your CO Alarm is sounding, the red alarm light in the centre of the cover will be flashing. Testing both your CO Alarms and Smoke Alarms weekly will help you and your family to clearly distinguish between them in an emergency. 19

****** Page 22 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 22 6. MAINTAINING YOUR CO ALARM Clean the outside case by occasionally wiping with a clean damp cloth, (disconnect the mains supply at the distribution/fuse board first). Do not use any cleaning agents, bleaches, detergents or polishes, including those in aerosol cans. Avoid spraying air fresheners, hair spray, paint or other aerosols near the CO Alarm. Do not place air fresheners near the unit. Use the narrow nozzle of a vacuum cleaner to remove fluff and other contamination from the cover slots to ensure CO gas can reach the sensor. Caution: Do not paint the CO Alarm. Remove the CO Alarm when decorating. Do not allow water or dust to contaminate the alarm. Warning: Do not open or tamper with the CO Alarm. There are no user serviceable parts inside apart from the sensor module – see below. This can damage the unit and may expose the user to shock or fire hazards. How to disconnect and remove the alarm: (1) First disconnect the mains supply to the CO Alarm circuit at the distribution/fuse board. (2) Remove tamperproofing screw if fitted (see Figure 1). (3) Release catch, as shown in Figure 1, and slide unit off mounting plate. SENSOR MODULE REPLACEMENT Replace the sensor module after 5 years operation (or by the date for sensor replacement on the side of the unit). 20

****** Page 23 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 23 After 5 years operation, the amber light will flash once every 40 seconds (without a beep) to indicate the sensor should be replaced. (Note: cover the ‘replace sensor’ label on side of unit with the new ‘replace unit’ by label supplied with the new sensor). It must also be replaced if the amber light flashes and the unit beeps every 40 seconds as this indicates the sensor is faulty. Remove the alarm from the mounting plate as described above. Pull out the sensor module from the rear. Replace with a new sensor module (Model No. Ei 261 MEN) (Contact Aico or Ei Electronics, for your near- est module supplier). Carefully align the module including the connector pins and push firmly home. Slide the alarm back on to the mounting plate. Reconnect the mains supply. Wait 4 minutes for the new sensor to stabilise and then press the test button – the horn should sound. Check the alarm as described in section 4 above. Note: When the second sensor has completed its 5 years of operation the amber light will flash every 40 seconds. The sensor module can only be replaced once. The entire unit must be replaced after 10 years. The date for replacing the entire unit is given on the base. 7. LIMITATIONS OF CO ALARMS (1) The Ei 261 EN/261DEN CO Alarm will not work without mains power if the rechargeable cells are depleted. The green power light must be on at all times as far as possible. (2) Carbon Monoxide must enter the unit for it to be detected. There may be Carbon Monoxide in other areas of the house (e.g. downstairs, in a closed room etc). but not in the vicinity of the CO Alarm. Doors, air draughts and obstructions can prevent the CO reaching the Alarm. For these reasons we recommend 21

****** Page 24 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 24 CO Alarms are fitted both near and in bedrooms, particularly if bedroom doors are closed at night. Additionally install in rooms where members of the household spend much of their time, and in rooms with potential sources of CO gas. (3) The CO Alarm may not be heard. The sound output is loud but it may not be heard behind a closed door or if it is too far away. Interconnecting CO Alarms greatly improves the probability that they will be heard. The Alarm may not wake up somebody who has taken alcohol or drugs. The alarm sound may be masked by other sounds such as T.V., stereo, traffic noise etc. Fitting CO Alarms on either side of closed doors will improve their chance of being heard. This CO Alarm is not designed for people with impaired hearing. (4) CO Alarms don’t last indefinitely. CO Alarms are sophisticated electronic devices with many parts. Although the alarm and its component parts have undergone stringent tests, and are designed to be very reliable, it is possible that parts can fail. Therefore, you should test your CO Alarm weekly. The CO Alarm sensor must be replaced after 5 years operation. The complete unit must be replaced after 10 years. (5) CO Alarms are not a substitute for life insurance. House-holders are responsible for their own insurance. The CO Alarm warns of increasing CO levels, but we do not guarantee that this will protect everyone from CO poisoning. (6) CO Alarms are not suitable as early warning Smoke Alarms. Some fires produce Carbon Monoxide, but the response characteristics of these CO Alarms are such that they would not give sufficient warning of fire. Smoke Alarms must be fitted to give early warning of fire. The CO Alarm does not detect the presence of natural gas (methane), bottled gas (propane, butane) or other combustible gases. Fit combustion gas alarms to detect these. WARNING: THIS CO ALARM IS DESIGNED TO PROTECT INDIVIDUALS FROM THE ACUTE EFFECTS OF CARBON MONOXIDE EXPOSURE. IT WILL NOT FULLY SAFEGUARD INDIVIDUALS WITH SPECIFIC MEDICAL CONDITIONS. IF IN DOUBT CONSULT A MEDICAL PRACTITIONER. 22

****** Page 25 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 25 8. HOW TO PROTECT YOUR FAMILY Follow these guidelines to reduce the risk of Carbon Monoxide poisoning. (1) (2) (3) (4) (5) (6) Know and look out for tell-tale signs that Carbon Monoxide may be present. These include:- The CO Alarm warning of abnormal levels. Staining, sooting or discolouration on or around appliances. A pilot light frequently going out. A strange smell when an appliance is working. A naked gas flame which is yellow or orange, instead of the normal blue. Family members (including pets) exhibiting the “flu-like” symptoms of CO poisoning described above. If any of these signs are present get the appliance checked out by an expert before further use. If family members are ill get medical help. Choose all appliances and vehicles which burn fossil fuels such as coal, oil, natural/bottled gas, paraffin, wood, petrol, diesel, charcoal etc. with care and have them professionally installed and regularly maintained. These appliances must “breathe in” air to burn the fuel properly. Know where the air comes from and ensure vents/air bricks etc. remain unobstructed (particularly after building work). The appliances must also “breathe out” the waste gases (including the CO) — usually through a flue or chimney. Ensure chimneys and flues are not blocked or leaking, and get them checked every year. Check for excessive rust or cracks on appliances and pipe work. Never leave your car, motor bike or lawnmower engine running in the garage with the garage door closed. Never leave the door from the house to the garage open if the car is running. Never adjust your own gas pilot lights. 23

Children should be warned of the dangers of CO poisoning and instructed never to touch, or inter- fere with the CO Alarm. Do not allow small children to press the test/hush button as they could be subjected to excessive noise when the unit alarms. Leaving windows or doors slightly open (even a few inches) will significantly reduce the risk of high levels of CO occurring. The high levels of draught-proofing in modern houses reduces ventilation and can allow dangerous gases to build up. Install CO Alarms in all the areas recommended in this leaflet. Recognise that CO poisoning may be the cause when family members suffer from “flu-like” symp- toms when at home but feel better when they are away for extended periods.

When the unit is alarming, after sensing CQ pressing the test/hush button will immediately stop the horn (the red light will continue to flash). If CO is still present the red light and the horn will turn on again after about 4 minutes. The unit can only be silenced once during a CO incident. At 300 ppm CO the unit cannot be silenced. (With interconnected units, the hush only works on the alarm sensing CO). Pressing the test button also causes the unit to check for CO, 4 seconds later to facilitate testing in CO gas. It gives 3 beeps and the red light flashes to indicate the CO level, if CO is sensed and then resets. 70 seconds.

It can power the unit in alarm for over 2 hours. The unit beeps every 40 seconds if cells are depleted. Up to 12, Ei 261 EN/261 DEN Alarms can be interconnected, so that when one senses CO, all alarm. This can be connected, using the interconnect line. Use relay contacts for for switching valves etc. A unit will indicate if it has been in alarm previously by flashing the red light for 2 seconds every 40 seconds (2 flashes for 50 ppm CO, 4 flashes for 100 ppm CO and 8 flashes, for 300 ppm CO). When the test button is pressed the red light flashes as per table B and also indicates the previous CO alarm level detected. The memory is cleared by holding down the test button until the red light stops flashing. Range 50 – 300ppm CO, Resolution 5 ppm CO.

If it is off check the wiring, fuse, circuit breakers etc. (2) Hold the test button down for at least 5 seconds. 2. ALARM BEEPS AND AMBER LIGHT FLASHES EVERY 40 SECONDS: If the alarm beeps and the amber fault light flashes every 40 seconds, the CO sensor is probably defec- tive. Press the test/hush button to reset the unit. If the beeping and the amber light flashing re-occurs replace sensor module. 3. ALARM BEEPS EVERY 40 SECONDS (without amber light flashing) Rechargeable cells depleted. Re-connect mains if green light is off. 4. ALARM SOUNDS FOR NO APPARENT REASON: Follow the detailed instructions on the top of page 2. entitled “What to do when the alarm sounds”. there are still problems: (1) Ensure there are no fuel-burning appliances in the vicinity which could be leaking CO gas (e.g. even from next door). 28

****** Page 31 ****** B15404-RO-261EN-UC-ENG 31/5/07 2:01 PM Page 31 (2) Ensure there are no fumes in the area (e.g. paint, thinners, alcohol, hair spray, chemical cleaners aerosol sprays etc). (3) Ensure there is no outdoor source of CO in the vicinity (e.g. a car with engine running, heavy traffic, heavy air pollution, barbecue fumes etc). (4) Press the test/hush button to silence the alarm. If the unit continues to sound it is possibly defective and should be replaced, follow the instructions in section 5 on “How to disconnect and remove your alarm” and then see section 10 “Getting the CO Alarm Serviced”. 4. TEST/HUSH BUTTON DOES NOT SILENCE ALARMS: If there are a number of alarms interconnected and they are all sounding, pressing the test/hush button on the unit sensing CO (i.e. the one with the red light flashing) will silence the system. Pressing any other test/hush button will not silence the alarms. Hush button will only silence the unit once at CO levels less than 300 ppm CO during a CO incident. 29
