4.4.4 Replacing the AV-AMP-80 Audio Amplifier Module
If replacing an AV-AMP-80 audio amplifier module, remove power (AC and battery) from the system. When
replacing the amplifier remove the amplifier and its attached mounting plate from the enclosure and replace with a
new amplifier mounted to its own mounting plate.
Note: The AV-AMP-80 audio amplifier module is preassembled to a mounting plate which is utilized for
heat sinking the AV-AMP-80 amplifier. This plate must remain assembled to the amplifier. The new AV-AMP-
80 audio amplifier module will be assembled with its own mounting plate.
Remove all field wiring terminal blocks from the audio amplifier module. Remove the two (2) screws [p] from the
audio amplifier assembly’s mounting plate. Carefully slide the audio amplifier assembly from under the back box
mounting tabs [
*
] located on the left side of the audio amplifier mounting plate (see figure 24).
Carefully slide the new audio amplifier assembly into the back box mounting tabs [
*
] and reinsert / tighten the
previously removed two (2) screws [p]. It is critical that these screws be tightly secured as they are required for
proper earth ground connection. Reinstall all removed field wiring terminal blocks from the audio amplifier module
and reconnect AC and battery power to the system.
Failure to tighten screws will defeat the protection circuitry designed to protect the module from damage
due to lightning and static electricity.
4.5 AV-ZS Audio Zone Splitter Module
The AX-CTL-1L, AX-CTL-2 or AX-CTL-4 optional AV-AMP-80 audio amplifier is capable of accommodating an AV-
ZS, audio zone splitter module.
The AV-ZS audio zone splitter module is designed to take one or both AV-AMP-80 amplifiers (audio notification
appliance circuits) and split these into additional audio notification appliance circuits, each capable of delivering 20
Watts per circuit. If splitting two (2) AV-AMP-80 amplifiers (audio notification appliance circuits), each amplifier is
split into two (2) audio notification appliance circuits. If splitting one AV-AMP-80 amplifier (audio notification
appliance circuit), the amplifier is split into four (4) audio notification appliance circuits.
