The following is a typical example of an emergency broadcast operation. This procedure requires the optional EV-200M Voice Announcement Board to be installed.

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 all zones for a preset number of repetitions. The EMERGENCY indicators on the RM-200M and the TOA VM-2120 will light up. This broadcast terminates all current general-purpose broadcasts.

Step 2. Evacuation Broadcast

After the Alert broadcast is complete, the system automatically switches to the Evacuation broadcast. A pre-recorded Evacuation signal tone and announcement will be alternately broadcast to the entire zone.

Step 3. Live Microphone Announcement

During either the Alert or Evacuation broadcast, you can make a live announcement. Hold down the Remote Microphone’s TALK key to interrupt the current emergency broadcast and speak into the microphone. The announcement will be broadcast to the entire zone.

When the TALK key is released, the microphone announcement terminates, and the system reverts to the Evacuation broadcast.

Step 4. Emergency Broadcast Termination

To terminate the Emergency broadcast, activate the Emergency Stop input from the corresponding connected external equipment (e.g., a fire alarm panel). The unit will return to the general-purpose broadcast mode it was in before the emergency began, and the EMERGENCY indicators will turn off.

Notes:

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

• Emergency broadcasts cannot be terminated from the Remote Microphone.

• If the unit is not equipped with the EV-200M, 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 (or set the lock lever to ON).

2. Make your announcement into the microphone.

3. Release the press-to-talk key (or set the lock lever to OFF).

Background Music Broadcast:

1. Select the desired broadcast zone using the ZONE 1-5 keys or the ALL key on the TOA VM-2120 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 controls on the front panel.

You can perform four types of broadcasts: All-Zone, Individual Zone, Group, and Message broadcasts. Note that all announcements from the Remote Microphone are broadcast at the maximum volume level, bypassing the master, zone, and external speaker attenuator controls.

Operation common to All-Zone, Individual Zone, and Group Broadcasts:

Step 1: Select Broadcast Destination

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

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

• For Group Broadcast: Press the desired GROUP key. Both the group’s indicator and the indicators of the zones assigned to that group will light. (Groups must be pre-programmed in the TOA VM-2120).

Step 2: Check the Busy Indicator

• If the Busy indicator is off, other equipment is not in use.

• If it flashes orange, you cannot make a broadcast.

• If it flashes green, you can interrupt the other broadcast.

Step 3: Start of Broadcast

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

Step 4: End of Broadcast

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

Message Broadcast Operation (Requires EV-200M board):

Step 1: Start of Broadcast

Select the desired message by pressing the MESSAGE key (1-5). The Message indicator will light, and the pre-recorded voice message will be broadcast to its designated group. If the indicator does not light, a higher priority broadcast is in progress.

Step 2: End of Broadcast

The broadcast ends automatically, and the Message indicator goes out. You can also press the MESSAGE key again during the broadcast to terminate it.

Making a broadcast with a higher priority cuts off a current lower-priority broadcast. When the higher-priority broadcast is finished, the original broadcast is automatically restored. The priority levels are as follows, from highest to lowest:

• Highest Priority: Emergency Broadcast (Alert and Evacuation messages).

• Priority 1: Can be set for Inputs 1-3, Telephone Paging, Remote Microphones 1-4, and Messages 1-5.

• Priority 2: Can be set for Inputs 1-3, Telephone Paging, and Remote Microphones 1-4.

• Priority 3: Can be set for Inputs 1-3, Messages 3-5, and 5 different chimes.

• Priority 4 (Lowest): BGM 1 and BGM 2.

The specific priority for each source can be configured using internal and external DIP switches. For broadcasts with the same priority level, the system can be set to one of three modes:

1. Last-come-first-served (factory preset): The newest broadcast interrupts the earlier one.

2. First-come-first-served: The current broadcast is given priority, and other broadcasts cannot be made.

3. Unit number priority: Broadcasts are prioritized based on the assigned unit number of the source (e.g., Remote Microphone No. 1 has priority over No. 2).

The TOA VM-2120 offers 5 different chime types for pre-announcements, which can be selected via the rear panel SETTINGS switches. It is also possible to disable the chime function.

Available Chime Tones:

• Four Built-in Chimes:

– 2-tone chime (factory preset)

– 4-tone chime (Up)

– Single-tone chime

– 4-tone chime (Up & Down) – An ascending tone sounds at the start and a descending tone at the end of the broadcast.

• One Pre-recorded Chime: Requires the optional EV-200M board and a recorded chime on the CF card.

How the Chime is Used:

• For Inputs 1-3: When an input is set to MIC level and broadcast is activated by remote control (CTRL IN), a chime automatically sounds.

• For Telephone Paging: You can select whether or not to sound a chime via the rear panel SETTINGS switch.

• Independent Chime Activation: A chime tone can be sounded remotely by activating the “Chime activation” pin on the CONTROL I/O connector. This is used for Priority 3 broadcasts not activated by remote control.

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 (optional accessory) to the unit using its accessory screws and plain washers. Do not use the screws removed in Step 2.

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

This procedure allows you to assign specific broadcast zones (1-5) to a group (1-5). For this example, we will assign Zones 2, 3, and 4 to Group 2.

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. After 2-3 seconds, all indicators for Zones 1-5 will begin to flash. Release the ZONE 1 and ZONE 2 keys. The unit is now in group setting mode, with the flashing indicators representing Groups 1-5.

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.

Step 3. Enter Zone Selection Mode for the Group

Press the POWER switch. The unit is now in Zone Selection mode for Group 2. The ZONE 2 indicator will continue to flash slowly (indicating Group 2 is selected and Zone 2 is set by default). The other zone indicators will flash normally.

Step 4. Set the Zone Numbers for the Group

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

Step 5. Program the Setting

Press the POWER switch. The settings for Group 2 (Zones 2, 3, and 4) will be programmed. The unit automatically returns to Step 2 (Group Number Selection), allowing you to set the next group. Repeat steps 2 through 5 for other groups.

Step 6. Complete the Setting

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