4.4.3 Installing the AV-AMP-80 Audio Amplifier Module
The AV-AMP-80 audio amplifier module provides digital audio capabilities for the Axis
AX
Intelligent Fire Alarm
Control Panel. It requires separate 24 VDC originating from an AX-PSU-6 power supply charger. As previously
indicated the AV-AMP-80 audio amplifier module is mounted below the AX-CTL base card on the left side of the
back box (see figure 21).
To install the AV-AMP-80 audio amplifier module slide the AV-AMP-80 mounting plate tabs under the two (2) tabs
located on the lower left side of the back box below the AX-CTL base card. Secure the top end of the AV-AMP-80
mounting plate to the back box standoffs with the provided two (2) screws (see figures 24).
Note: The AV-AMP-80 is pre-assembled on a mounting plate, do not remove from the mounting plate as
this is part of the assembly and is required for heat sinking the AV-AMP-80. If replacing, the new AV-AMP-
80 will be supplied pre-assembled to a mounting plate.
