Audio Alarm Verification (Two-Way Voice Feature)

This feature allows the central station operator to listen, talk to or conduct a two-way conversation with an
individual(s) at the premises. It also assists the operator in gathering information about the nature and
location of the alarm that may be helpful in responding to police and fire departments. All Lynx Plus Series
control panels are capable of supporting the Two-Way Voice feature. The Lynx Plus Series does not make
system announcements when the Two-Way voice feature is active.
Activation
Fire and CO alarms will not trigger an AAV session. A new Fire or CO alarm will end an AAV session that is
in progress.
The Lynx Plus Series sends the "alarm message" followed by a "Listen-in-to-Follow message" (Contact ID®
code 606) to the Central Station. The Listen-in-to-Follow message causes the Central Station's digital
receiver to temporarily hold the phone line for approximately 1-minute. When the Lynx Plus Series receives
the "kissoff" from the central station, indicating that the alarm message has been received, the Two-Way
Voice (AAV) feature is activated in the (default) "Listen Mode" and sirens and keypad sounds are
discontinued. The Lynx Plus Series transmits a beep acknowledgment to the Central Station, once per
second. The beep alternates between two tones and indicates that the Lynx Plus Series is waiting for a
session command from the Central Station operator. Once a command is issued the beep acknowledgement
is discontinued, however, if a command is not issued within two minutes the system will "time out" and the
call will be terminated.
Operator Commands
The Central Station operator begins the session, which last 5 minutes, by entering one of the valid AAV
commands shown in the table below. The session may be extended 5 minutes, without changing the
operating mode, by pressing the [7] key on the touch-tone phone. Selecting another operating mode also
resets the session an additional 5 minutes. During the last minute of the 5 minute, session, the Lynx Plus
Series generates two beeps every 30 seconds to alert the Central Station operator that the session is about to
time out. The Central Station operator may then extend the session by pressing the [7] key on the touch-tone
phone. If the session is not extended the phone line is disconnected, and the session is ended. Sessions may
be ended at any time by pressing the [9] key on the touch-tone phone. The AAV modes are described as
follows:
Note: When entering AAV commands make sure the Central Station receiver has been disconnected from the
phone line, otherwise AAV commands may not go through.
Key
1 Talk Mode: Pressing the [1] key on the touch tone phone, enables one-way voice communication from the
central station to the violated premises, and allows the operator to talk communicate through the Lynx Plus
Series speaker. In this mode the ARMED (red) and READY (green) LEDs blink alternately.
2 VOX (Voice) Mode: Pressing the [2] key on the touch-tone phone, enables two-way voice communications
between the central station and the violated premises. In this mode the ARMED (red) and READY (green)
LEDs blink alternately.
3 Listen Mode: Pressing the [3] key on the touch-tone phone, enables one-way audio from the violated premises
to the central station. The Listen Mode is the start up default mode of the voice feature and allows the

pattern.
