RED SMOKE ALARMS RRURF (01) PDF DOCUMENT

• The installation of the RRURF Relay Unit with RF must be performed by a qualified electrician in compliance with relevant local Electrical Installation Regulations. Improper installation may pose risks of electric shock or fire hazards and can damage the product. This unit is not waterproof and should not be exposed to dripping or splashing.

• Connect the RRURF Relay Unit with RF to Alternative Energy Sources (Wind, Solar, UPS, etc.) – This product is designed to connect to a Pure or True Sine Wave 230V AC supply. If you intend to connect it to a power source utilising an inverter, such as a PV solar panel, ensure that the Total Harmonic Distortion (THD) is less than 5%. If you are uncertain about the THD specifications, please consult the inverter manufacturer. The same requirement applies to battery-powered Uninterruptible Power Supply (UPS) inverters.

• The relay base must not be powered from a light dimmer circuit.

NOTE: USERS ARE STRONGLY ADVISED TO READ THE MANUAL THOROUGHLY AND FOLLOW THE STEPS IN CHRONOLOGICAL ORDER TO ENSURE THE PROPER SETUP OF THE RELAY UNIT.

1.1 Ensure the mains power is disconnected from the circuit and the backup battery is turned off before installing the relay unit to ensure safety.

1.2 Securely attach the relay unit to the ceiling or wall according to the installation instructions to prevent injury. Select an appropriate mounting position near the mains supply and the device to be connected to the relay.

Note: Avoid metal surfaces or large metal objects that may interfere with the RF signal range.

1.3 If the incoming wiring is on the surface of the wall/ceiling, use appropriately sized conduit to connect with the unit. Carefully remove the knockout material with a sharp knife, ensuring no gaps remain when mated with the conduit.

Note: There is one suitable surface cabling knockout. The other two surface entries are not recommended, as the wiring may reduce the antenna signal. There is one rear entry knockout.

Ensure that the Relay Unit is securely mounted on the wall or ceiling, with house wires passing through it at this stage.

2.1 Connect the power supply wires (Live and Neutral) to the mains terminal block as illustrated in Fig. 2. (Tighten screws to a maximum torque of 0.5 Nm (5.1 kgf.cm)).

There are two relays in this RF base:

The relay terminal marked “FIRE” activates when the Relay Unit receives either a fire warning signal or a test/silence RF signal from the alarm device within the RF network, or a wired connection signal.

The relay terminal marked “FAULT” triggers when the Relay Unit receives a low battery or fault signal from the alarm device within the RF network.

Note: The “FIRE” and “FAULT” relays are independent of each other.

Note: Please refrain from connecting a green/yellow or copper earth wire to any terminal, as grounding the unit is not permitted.

2.2 Connect the L (Live) wire from the auxiliary device power supply to the COM (Common) terminal.

2.3 Depending on the control requirements of the auxiliary device, connect either the NC or NO contact of the relay to the auxiliary device.

• If the relay is used to interrupt a boiler during an alarm, use NC. (refer to Fig. 4)

• For a beacon that should only activate during an alarm, use NO. (refer to Fig. 5)

• Identify the type of auxiliary device and connect it to the “FAULT” relay terminal (refer to Fig. 7 and 8).

2.4 Alternatively, if the auxiliary device shares the same power source circuit as the relay (i.e., 230VAC), insert a linking wire between the L (Live) terminal and the C (Common) terminal of the relay unit. Then, connect the NC or NO contact of the relay unit, depending on the requirement, to the auxiliary device. Connect the N (Neutral) terminal from the relay to the auxiliary device as depicted in the diagrams. (refer to Fig. 6)

Note: The same wiring method can also be applied to the “FAULT” Relay Terminal. (refer to Fig. 9).

The Red Original RRURF relay can be set to either continuous or pulse operation. This feature only applies to the “FIRE” relay.

Default Setting: Continuous Operation

By default, a track pin cap should be placed in the right “C” (Continuous) position. In this mode, the relay switches on when a smoke alarm detects a fire and switches off when the alarm condition ends.

Alternative Setting: Pulse Operation

To set the relay for approximately 5 seconds of activation upon receiving a signal, carefully remove the black pin cap and place it over the left “P” (Pulse) pin. This setup is for systems that require momentary activation.

Note: With the switch set to the “C” (Continuous) position, the alarm signal will engage the latching relay until a cancel signal is received. The “FAULT” Relay Terminal operates exclusively in latching mode.

4.1 Activate the battery by sliding the switch to the “ON” position.

4.2 Confirm the green power indicator is illuminated for proper operation.

4.3 Replace the cover and secure it in place using the provided screws.

5.1 Apply mains power to activate the RRURF Relay Base. The green LED indicator on the cover will light up continuously, indicating the presence of AC power. Turn ON the backup battery to ensure proper operation.

5.2 If the green light is not illuminated, first disconnect the mains power, then remove the base plate, and verify the accuracy of the wiring connections.

6.1 RF WIRELESS PAIRING

To create a new RF network with the RRURF as Master:

• Press and hold the RF Pairing button on the Relay Unit.

• Use a pin to press and hold the pairing button for 10 seconds until the Red LED illuminates. This will set the RRURF as the network Master.

To join an existing RF network as a Slave:

• Press the RF Pairing button on the Relay Unit twice. The Red LED will flash 5 times to indicate a successful connection.

To exit RF pairing mode:

• To exit RF pairing mode, press the RF pairing button once. The RRURF Relay Unit will automatically exit RF pairing mode after 30 minutes of inactivity. The red LED will turn off, and the system will return to standby mode.

Clear Pairing Memory:

Note: Once a new RF network is established, the system will automatically clear old pairing records. This will prevent the unit from being controlled by devices outside the group.

• Press the RF pairing button 5 times. The red LED on the alarm will flash 10 times.

Press and hold the Test button on any paired RF alarm for up to 5 seconds. After a brief moment, all alarms should sound, and the relay unit will activate. Check that the auxiliary device operates as intended. Release the test button after 60 seconds and observe if all interconnected devices stop sounding. The relay will stop operating once the alarm signal deactivates. Repeat this process for all RF devices within the network.

The “FIRE” relay feature can be tested by pressing the test button on any smoke alarm in the RF network. The “FIRE” relay on the Relay Base must activate immediately and remain active for the duration of the test signal. The “FAULT” feature of the Relay Base must be tested according to the “Low Battery or Fault Signal from a Connected Smoke Alarm” check for proper functionality.

The “FAULT” feature will activate if there is a low battery or fault condition from a connected smoke alarm.

Note: Up to 20 RF devices can be interconnected to a single relay.

1. PERFORMANCE CHECK INSTRUCTIONS

(a) Test the alarms monthly. Press the Test button on any alarm in the RF network. Check if the device, like house lights, turns on. Release the test button. The device should turn off. If not, check the circuit breaker, fuse, and wiring.

(b) If the red LED flashes once every 10 seconds, it indicates a low battery. Replace the alarm whose red LED is flashing.

(c) Ensure the battery power switch is in the “ON” position. If not, switch it ON. If the unit still flashes red, the relay unit may be faulty and requires replacement.

2. THE RELAY SWITCHES

Press the alarm Test Button and verify the relay switches function.

3. THE BACKUP-BATTERY

To ensure the RRURF functions as expected, it is essential to periodically test the backup battery. This involves turning off the mains power and verifying that the auxiliary device operates correctly. After the test, restore mains power and confirm the green LED is ON.

If the RRURF does not respond during testing, follow these steps:

a. Ensure the RF Pairing button is held down until the RF light illuminates, confirming the activation of pairing mode. To join the RF network, press the RF pairing button two times. The LED will flash 10 times to indicate a successful connection. If the issue persists, clear the pairing memory. Refer to the instruction manuals of other devices in the system to ensure that their memories are also cleared before initiating the pairing procedure again.

b. If clearing the pairing does not improve signal reception, consider relocating the RRURF and/or the initiating alarm unit. The range of the previously paired devices can currently be affected by the building’s use or if there have been recent changes. If the position has been changed, carry out the “TESTING THE RF NETWORK” procedure.

If you observe any indication from the RRURF besides the normal green LED “On,” refer to the table below to learn about the current status of the prestress and the appropriate action to be taken.

While the RRURF transmitting and receiving system is highly reliable and tested to government standards, it may not prevent or extinguish fires, or it may fail to wake all individuals. Transmitters may experience blockages from radio signals operating on or near their frequencies, such as those from cordless phones or baby monitors. Receivers may experience blockages from signals from other RF devices.

Regular testing of the alarms is recommended, ideally on a monthly basis, to verify the proper functioning of the system and address any potential interference from new electronic devices, renovations, and provides early warning of faults and other issues.
