3.2 AV-AMP-80 Audio Amplifier Module
The AV-AMP-80 audio amplifier module provides the digital audio capabilities (live voice communications with AV-
VBM) of the AV-VBM audio panel w/microphone and AV-VB distributed audio booster and requires 24 VDC nominal
power from the AX-PSU-6 (see figure 4).
The AV-AMP-80 contains two (2) electrically independent Class “A” or “B”, 40 Watt @ 25 Vrms, amplifiers (Audio
Notification Appliance Circuits - ANACs) [controlled together or amplifier two dedicated as a backup to amplifier
one]. Each amplifier (audio notification appliance circuit) is activated whenever one of the AV-AMP-80 trigger inputs
is activated (trigger input activation on AV-VBM is via the AV-SM switch/LED module).
In addition to providing the two (2) electrically independent amplifiers (audio notification appliance circuits), the AV-
AMP-80 has an integral two (2) programmable, flash-based, digital message/tone generator. Messages are freely
programmable and can be tailored to meet specific installation requirements.
There are three (3) trigger inputs on the AV-AMP-80 (two of these, trigger input 1 and trigger input 2, are prewired
on the AV-VBM to the AV-SM switch/LED module) for activating the audio amplifiers; trigger input 1, trigger input 2
and trigger input 3.
Trigger input 1 when activated, not only turns on both amplifiers (audio notification appliance circuits) it also
activates programmed message/tone #1 and plays this message over the audio notification appliance
circuits. Trigger input 1 has a higher priority than trigger input 2. If both trigger inputs are active at the same
time, programmed message/tone #1 will be broadcasted.
Trigger input 2 when activated plays message/tone #2 on both amplifiers (audio notification appliance
circuits).
Trigger input 3 sets the AV-VBM audio panel w/microphone and/or AV-VB distributed audio booster to
“booster mode”, this allows any external audio signal ( 25vrms) to be broadcasted out of one or both of the
AV-AMP-80 amplifiers (based on wiring). This trigger input has the highest priority, if both trigger input 1
and 2 are active during a trigger input 3 activation, amplifiers will broadcast the external audio signal. This is
how live voice communications are broadcasted through the AV-VB distributed audio booster amplifiers. By
activating trigger input 3 on the AV-AMP-80 of the AV-VB distributed audio booster, microphone
communications from an AxisAX integrated audio intelligent fire alarm control panel, an AV-VBM audio panel
w/microphone or a host EVAC system can be rebroadcasted out of the AV-VB distributed audio booster
amplifiers.
Designed into the AV-AMP-80 is a dedicated Form “C” trouble relay contact which transfers on any amplifier and/or
audio notification appliance circuit trouble/failure. This trouble/fault relay contact is prewired in the AV-VBM to the
AV-SM switch/LED module. In the AV-VB the trouble/fault relay contact must be monitored by the host fire alarm
control panel.
Note: The trouble relay contact, in addition to the power supply charger trouble/fault relay contact, located
on the AX-PSU-6 power supply charger, are prewired in the AV-VBM panel to the AV-SM switch/LED
module. These contacts located in both the AV-VBM and AV-VB must be monitored by the host fire alarm
control panel to maintain proper supervision of the AV-VBM audio panel w/microphone and AV-VB
distributed audio booster. If the AV-VB is utilized as a PBUS (485) amplifier trouble/fault monitoring is
accomplished by the AX-CTL base card via the PBUS (485) connection.

3.2.1.1 PBUS (485) AV-AMP-80 Wiring
As previously indicated, AV-VB distributed audio boosters can also be configured for use in AxisAX PBUS (485)
amplifier installations. When an AV-VB is utilized in this configuration, the amplifier is wired as a PBUS (485) floor
(area) amplifier. As a PBUS (485) floor (area) amplifier the amplifier is connected an AxisAX fire alarm control
panel’s AX-CTL base card (PBUS) and all control / operation is done via the associated base card. In addition to
wiring to an AX-CTL base card, the amplifier will also monitor the associated AX-PSU-6 power supply and report its
status to the AX-CTL base card (see figure 5).
Note: For additional information regarding AV-VB distributed audio booster PBUS (RS485) use, refer to the
associated AxisAX audio fire alarm control panel manual.

3.2.5.2 AV-ZS Wiring
Wire 24 VDC (from AV-AMP-80 power output terminals) to the power input terminals of the AV-ZS audio zone
splitter module. Wire one or both AV-AMP-80 amplifiers (audio notification appliance circuits) to the Audio Input 1
and Audio Input 2 terminals of the AV-ZS module and set jumpers J6 and J7 to their appropriate position [1 audio
input or 2] (see figure 10).
Note: The AV-ZS audio zone splitter module includes a fail-safe trouble relay contact which opens on any
split audio notification appliance circuit trouble condition or on loss of 24 VDC input power. This trouble
relay contact must be monitored by the Host fire alarm control panel (see figure 10).
