TOA SV-200MA (01) PDF Document

When installing the TOA SV-200MA system, please adhere to the following safety warnings:

• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.

• Use the unit only with the voltage specified on the unit. Using a higher voltage may result in fire or electric shock.

• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down and causing personal injury and/or property damage.

• For the VM-2120/-2240 amplifier, do not cut, kink, otherwise damage nor modify the power supply cord. Avoid using the power cord near heaters, and never place heavy objects, including the unit itself, on the power cord.

• The apparatus shall be connected to a mains socket outlet with a protective earthing connection.

• The socket-outlet shall be installed near the equipment and the plug (disconnecting device) shall be easily accessible.

• For the RM-200M/-210 remote microphone, install the unit only in a location that can structurally support the weight of the unit and the mounting bracket.

• Do not use methods other than those specified to mount the bracket. Extreme force is applied to the unit, and it could fall off, possibly resulting in personal injuries.

• Use nuts and bolts that are appropriate for the ceiling’s or wall’s structure and composition. Failure to do so may cause the unit to fall, resulting in material damage and possible personal injury.

When using the TOA SV-200MA system, please follow these safety precautions:

• To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside. Refer all servicing to your nearest TOA dealer.

• Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.

• Do not insert metallic objects such as pointed objects and coins, or flammable materials in the unit’s openings, as this may result in fire or electric shock.

• Do not touch a plug during thunder and lightning, as this may result in electric shock.

• For the VM-2120/-2240 amplifier, should you find any irregularity during use (smoke, strange smell, water ingress, unit dropped, damaged power cord, malfunctioning), immediately switch off the power, disconnect the power supply plug, and contact your nearest TOA dealer. Do not attempt to operate the unit in this condition.

• When replacing a fuse, use only the supplied type. Using any other fuse may cause fire or electric shock.

Handling Precautions:

• To clean, first switch off the power supply, then wipe with a dry cloth. For heavy dirt, use a cloth damped in a neutral cleanser. Never use benzene, thinner, or chemically-treated cleaning cloths.

• When the EV-200M board is mounted, never move the unit with the Flash Card inserted, as it may cause failure.

• Avoid inserting or withdrawing the CompactFlash card while the unit is powered on.

Installation Precautions:

• Do not install the unit in locations exposed to direct sunlight or heaters.

• Avoid installing or storing the unit in dusty or humid locations.

• Keep the unit away from equipment that generates high-frequency noise, like fluorescent lamps or PCs.

• For the amplifier, do not block ventilation slots. Keep at least 50 mm of space on the right and left sides for heat radiation.

• Never connect the AC power cord to a voltage other than that specified.

• To avoid oscillation, keep input cables away from output cables, especially in an equipment rack.

• If hum noise occurs due to a ground loop, connecting the rear signal earth terminal to the body of connected equipment may reduce it.

• Never connect two amplifier outputs in parallel.

The system which includes the TOA SV-200MA board has the following features:

• Broadcasts of up to 480 W can be made to up to 10 zones individually or simultaneously (when 2 VM-2240’s are used).

• Permits monitoring of individual speaker line or power amplifier failures for status indication (Requires the optional TOA SV-200MA Surveillance Board).

• Reproduces 5 general-purpose messages, 1 chime tone, and 2 emergency messages (Requires the optional EV-200M Voice Announcement Board).

• Four different built-in chimes and prerecorded chime tones can be selected to attract attention to broadcasts.

• Backup battery maintains operation during power failures.

• Emergency broadcast based on the EN60849 Standard provides prerecorded voice instructions.

• Emergency broadcast bypasses the amplifier volume control and external attenuator.

• Features broadcast priority levels: the highest for Emergency broadcasts and 4 levels for general-purpose broadcasts.

• Supports speaker lines for 100 V, 70 V, or 50 V applications.

• Up to 4 remote microphones can be connected, with a total cable extension of up to 800 m.

• Speaker zones can be programmed into up to 5 groups for group broadcast.

• Provides clear, distortion-free announcements due to internal compressor circuitry in the remote microphone.

The TOA SV-200MA Surveillance Board provides the following functions when mounted in the system amplifier:

• Surveillance input and output connector [SURVEILLANCE I/O]: A 25-pin, female D-sub connector that features an input to activate the surveillance (failure detection) function and an output to indicate the result.

• Failure Monitoring: It monitors for failures in the unit’s power amplifier section and ground faults on the speaker line, outputting the result to the front panel Failure Indicator [FAULT].

• Speaker Line Surveillance: This function is performed by suspending a broadcast when activated from external equipment or the board’s internal timer. During this pause, all zone indicators flash. If a speaker line short is detected, the [FAULT] indicator lights, and the corresponding zone indicator flashes.

• Speaker line impedance setting key [SET]: Measures and sets each speaker line’s reference impedance value, which is used for surveillance criteria.

• Line check key [CHECK]: Checks each speaker line impedance for line failure detection.

Follow this procedure for a typical emergency broadcast operation:

Step 1. Alert Broadcast

Open the RM-200 Remote Microphone’s Emergency broadcast switch cover and press the switch. A pre-recorded Alert signal tone and announcement will be alternately broadcast to the entire zone for a preset number of repetitions. The EMERGENCY indicators on the remote microphone and amplifier will light up. This action terminates all current general-purpose broadcasts. (This can also be activated by an external fire alarm system).

Step 2. Evacuation Broadcast

After the Alert broadcast repeats as programmed, the system automatically switches to the Evacuation broadcast. A pre-recorded Evacuation signal tone and announcement will be alternately broadcast to the entire zone. (This can also be activated directly by an external fire alarm system).

Step 3. Live Microphone Announcement

During either the Alert or Evacuation broadcast, you can make a live announcement.

3-1. Hold down the Remote Microphone’s Talk key. This interrupts the current emergency broadcast and allows you to speak to the entire zone.

3-2. When you release the Talk key, the announcement terminates, and the system reverts to the Evacuation broadcast.

Note: In Emergency Broadcast mode, the Talk key always operates in a “press-to-talk” manner, regardless of its setting.

To terminate the Emergency broadcast, activate the Emergency Stop input via the corresponding connected external equipment. The unit will then return to the general-purpose broadcast mode it was in before the emergency began, and the EMERGENCY indicators on the remote microphone and amplifier will go out.

Please note the following:

• Emergency broadcasts are always at the maximum volume level; master and zone volume controls are disabled.

• The emergency broadcast cannot be terminated from the Remote Microphone.

• If the broadcast is stopped using the amplifier’s Reset key, the unit may not return to its previous mode.

• If the system is not equipped with the optional EV-200M board, you can still enter emergency mode and make live announcements from the Remote Microphone to the entire area.

Microphone Announcements (When Operated by Control Input)

1. Continuously press the microphone’s press-to-talk key. (If it’s a lock lever type, set it to the ON position.)

2. Make your announcement into the microphone.

3. Release the press-to-talk key. (If it’s a lock lever type, set it to the OFF position.)

Background Music (BGM) Broadcast

1. Select the desired broadcast zone using the ZONE 1 – 5 keys or the ALL key on the amplifier’s front panel.

2. Start your background music equipment (e.g., CD player).

3. Adjust the sound volume using the BGM input volume control on the front panel.

4. Adjust the tone using the BGM treble/bass control on the front panel.

You can make four types of broadcasts: All-Zone, Individual Zone, Group, and Message.

Step 1: Select the Broadcast Destination

• For All-Zone Broadcast: Press the ALL-ZONE key. The All-zone indicator and all zone indicators will light up.

• For Individual Zone Broadcast: Press the key for the desired zone(s). The corresponding indicator(s) will light. You can select multiple zones.

• For Group Broadcast: Press the desired GROUP key. The group indicator and the indicators for all zones assigned to that group will light up.

• For Message Broadcast: Press the desired MESSAGE key (1-5). The Message indicator will light. The recorded message will be broadcast to its pre-programmed group.

Step 2: Check the Busy Indicator

• If the indicator is off, the system is ready.

• If the indicator flashes orange, another broadcast is in progress and you cannot interrupt.

• If the indicator flashes green, you can interrupt the current broadcast.

Step 3: Start the Broadcast (Press-to-talk operation)

3-1. Hold down the TALK key. A start chime will sound (if enabled), and the In-use indicator will light green.

3-2. After the chime, make your announcement.

Step 4: End the Broadcast

Release the TALK key. An end chime may sound, and the broadcast will terminate. The In-use indicator will go out.

(For “Lock operation,” a single press of the TALK key starts the broadcast, and a second press ends it.)

The installation of the TOA SV-200MA board must be done by a qualified service technician only. For the specific mounting method, refer to the separate instruction manual provided for qualified service technicians.

Step 1. Remove the 4 plastic feet from the unit’s bottom side.

Step 2. Remove the 2 screws on each side of the unit, located near the front.

Step 3. Fix the Rack Mounting Bracket MB-36 to the unit using its accessory screws and plain washers. Do not use the screws removed in Step 2.

Step 4. Mount the unit onto an equipment rack using the bracket’s accessory screws and fiber washers.

Note: If you are using a rack not made by TOA, you must prepare appropriate screws and washers separately.

The 25-pin D-sub female Surveillance I/O connector on the TOA SV-200MA has the following pin functions:

To assign broadcast zones to a group (e.g., assigning Zones 2, 3, and 4 to Group 2), follow these steps on the master amplifier:

Step 1. Enter Broadcast Group Setting Mode

Press and hold the ZONE 1 and ZONE 2 keys. While holding them, press and release the recessed Reset key with a pointed object. Release the ZONE 1 and ZONE 2 keys when all indicators for Zones 1-5 begin to flash (after 2-3 seconds). The unit is now in setting mode.

Step 2. Select the Group Number

Press the ZONE 2 key to select Group 2. The ZONE 2 indicator will begin to flash slowly, indicating Group 2 is selected for programming.

Step 3. Program the Group Number

Press the POWER switch. The unit will now be in Zone Selection mode for the selected Group 2. The ZONE 2 indicator will change from “quick flashing” to “slow flashing”, indicating Zone 2 is set by default.

Step 4. Set the Zone Numbers

Press the ZONE 3 and ZONE 4 keys to select them. The indicators for ZONE 3 and ZONE 4 will light up. Zones 2, 3, and 4 are now selected for Group 2.

Step 5. Program the Zone Number Setting

Press the POWER switch. The zones will be programmed, and the unit will return to the Group Number Selection mode (Step 2). You can now select and program another group.

Step 6. Complete the Group Setting

After all groups are set, press the Reset key with a pointed object to complete the setting mode and return the unit to broadcast standby mode.

Recording messages for the optional EV-200M Voice Announcement Board requires a TOA EV-350R Digital Announcer.

Recording Process:

1. Use the supplied CF card. Be sure to keep a 10-second or longer unrecorded portion on the card, as it’s used for the EV-200M board’s surveillance function.

2. Place the CF card into a CompactFlash card adapter and insert it into the memory card slot on the EV-350R’s front panel.

3. Set up the Program Number (P001-P008), Playback method, and other parameters on the EV-350R as required for your messages. Refer to the EV-350R operating instructions for detailed programming.

4. Determine the optimum “Output level” for each program during the recording process (Factory-preset is Graduation 6).

Caution:

• When the EV-200M board is mounted in the amplifier, never move the unit with the Flash Card inserted, as it may cause failure.

• Avoid inserting or withdrawing the CompactFlash card while the amplifier is powered on.
