General Information

An Audio Alarm Verification (AAV) module, such as the Eagle 124~ is an

add-on accessory that permits voice dialog between an operator at a central

station and a person at the alarm installation, for the purpose of alarm

verification.

Mter all messages have been sent during a reporting session to the primary

phone number, the control will trigger the AAV if at least one of the messages

was an alarm report. If Contact ID format is selected for the primary phone

number, the control will send a “listen-in to follow” message, which signals

the 685 to hold the phone connection for 1 minute.

Once the digital message is “kissed off’, the control w-illgive up the phone

line to the AAV module, without breaking connection with the central station.

At this time, all sirens and all continuous keypad sounds in all partitions will

be shut off.

W* Connections

The method used to trigger AAV is via the use of a 4204 or 4229 relay

module, as shown in the AAV comection diagrams that follow (one diagram

for connections when a 4285 VIP module is used, the other when the 4285 is

not used).

ROgramming

With at least one 2-line Alpha keypad (5137AD or 6139) connected to the

Partition 1 terminals, power up the system. If you had previously

connected the AC transformer to the control panel, you need only plug in

the trsmsformer (to 120VAC outlet) to power up the system.

Enter the programming mode by keying the following on the Alpha

keypad: Installer code (4 1 12)+8 00.

Press ml. OPTION SELECTION. Enter “4” for AAV monitoring.

“O”must be entered for UL installations (AAV disabled)
