Audio verification menu
The Audio verification menu lets you set up the audio verification module (AVM)
operation in partition 1. If you want audio verification for partitions 2 to 6, you must
install a standalone audio verification module and a four-relay output module (HOM)
(60-770) output for that partition.
Audio verification - partition 1 settings
Audio verify

This setting determines whether the system can be accessed by phone for
alarm verification.
Audio mode audio
verification
Shortcut: 09001
Default: 1
This setting determines how the audio verification module operates. Choose
one of the following:
• Instant (1): Allows the central station operator instant access for an audio
session by entering the AVM code or by pressing *
(if an AVM access code is
not programmed) upon completion of panel alarm report (see “Access
timeout” below). The panel does not report any alarms during the AVM
session except for fire alarms, even if the operator extends the session by
pressing any valid key.
• Callback (2): Allows the central station operator to place a call to the
premises within 5 minutes of the alarm report (panel picks up after one ring).
The operator must press *
or enter the AVM access code within 20 seconds
after ring. The panel does not report any alarms during the AVM session
except for fire alarms, even if the operator extends the session by pressing
any valid key.
• Callback silent (3):
Same as Callback, except premises phones do not ring.
Fire shutdown
Shortcut: 09002
Default: Off
This setting determines whether system sirens turn off during a fire alarm
audio session.
Silent talkback
Shortcut: 09003
Default: Off
This setting determines whether the central station operator can speak to
persons on the premises (on) or only listen (off) during a silent or duress
alarm audio session.
Access timeout
Shortcut: 09004
Default: 90 seconds
If the audio mode is set to Instant, then this setting determines how much
time (30 to 300 seconds, in 2-second increments) the central station
operator has to enter the AVM access code after the panel is accessed for
an audio session.
Beep delay
Shortcut: 09005
Default: 2 seconds
This setting determines how long AVM access beeps are delayed (0 to 300
seconds, in 2-second intervals) at the beginning of a two-way audio session.
