Installing the Audio Alarm Verification Module

Audio Alarm Verification (AAV) is not permitted

in UL installations.

• 685 Receiver software must be rev. 4.6 or

higher. Earlier versions will not hold the

phone line connection.

• Contact ID code for “Listen-in to Follow” is

606. Contact ID is the only reporting format

that will send a “Listen-in to Follow.”

• If you are also using a 4285/4286 VIP

Module, be sure to follow

Figure 3-37

when

making connections.

The UVS consists of a UVCM and at least one UVST.

The UVCM board has a DC power jack and a 34-

position terminal block for making connections to a DC

power source, UVSTs, telephone lines, music source, or

to the 4286 VIP Module; and to a control panel’s voice

trigger and bell outputs (if required). Refer Figure 3-

28 for wiring connections. For a detailed explanation

of the wiring connections and the functions of the DC

power jack and terminal block positions, refer to the

installation instructions that accompany the UVS.

If the phone plug is disconnected from the

control, the premise’s phones will not operate.

NOTES:

• When the AAV indicates that the audio alarm

verification session is completed, all keypad

sounds are restored. Sirens are restored if the

alarm timeout period has not expired.

• As part of its fail-safe software, the control limits

all audio alarm verification sessions to 15 minutes.

This is because once the session begins, the AAV

Module controls the duration.

• If a new Fire alarm should occur during a

session, the control breaks the phone connection

and sends the new Fire Alarm report, then re-

triggers the AAV Mode. All other dialer messages

triggered during ongoing conversation are held

until either the AAV Module signals that it is

inactive, or the 15-minute timeout occurs.
