Table 23. Audio verification
Function Default Description
Audio mode Off 1 = Instant. Panel stays online with central station for an instant audio session.
2 = Callback. Panel hangs up and waits for a callback from the central station operator
before starting an audio session.
Off = No audio verification.
Fire shutdown Off Determines whether system Fire sirens are silenced during a two-way audio session (on)
or not (off). Beeps sound every 10 seconds while sirens are silenced.
Panic talk Off Determines whether the central station operator can talk to the user during a silent
alarm (off) or just listen in on the premises (on). Silent alarms occur when sensors
learned into groups 02 or 03 are tripped, when the duress code is entered, or when the
panel Police button is pressed and the Silent Panel Police Panic option is turned on.
Vox Rx gain 06 Determines the receiver gain level during two-way audio sessions. If the VOX is switching
the speaker on when the central station operator is not talking, lower both this setting
and the VOX mic gain setting. If the VOX is not switching the speaker on when the central
station operator is talking, raise this setting and lower VOX Mic Gain setting. Changing
this setting does not affect speaker volume.
Vox mic gain 24 Sets the mic gain (sensitivity) that triggers the voice-activated switching (VOX). Room size,
acoustics, and furnishings where the panel or Interrogator 200 are located will influence
the setting. Gain range is 01 (lowest) to 64 (highest).
Vox mic gain rng 64 Sets the gain range for voice-activated switching (Vox). Range is 01 (lowest) to 64
(highest). For best results, this option should be set equal to or greater than Vox mic gain.
Note: This option works in conjunction with Vox mic gain. It is important to follow the
setting recommendations as described to achieve acceptable operation.
Manual mic gain 64 Determines the gain level (sensitivity) during two-way audio sessions when audio mode
is set to 0 or 1 (speak). Room size, acoustics, and furnishings where the panel is located
will influence the setting. Gain range is 01 (lowest) to 64 (highest).
