4.5.2 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 26).
Refer to Axis
AX
Wiring Guide Section 9.
Note: The AV-ZS audio zone splitter module reports status open circuit, short circuit and grounds via the
associated AV-AMP-80 amplifier (audio notification appliance circuit). In addition, a fail-safe trouble relay
contact is available which opens on any splitter audio notification appliance circuit trouble condition or on
loss of 24 VDC input power, this trouble relay contact can be monitored for individual AV-ZS trouble
indication (see figure 26).
Note: Speaker circuit activation is unsupervised; wiring must be within 20 feet of the activation relay
contact. When the AV-ZS module is utilized with a PBUS (RS485) AV-AMP-80 amplifier, the “All” audio
notification appliance circuit activation input is constantly activate, thereby allowing for audio control via
PBUS (RS485) activation of the two (2) onboard AV-AMP-80 amplifiers. For additional information regarding
the installation and operation of the AV-ZS audio zone splitter module, refer to AV-ZS Audio Zone Splitter
Module Installation Instructions.
4.5.3 Replacing an AV-ZS Module
If replacing an AV-ZS audio zone splitter module, remove power (AC and battery) from the system. Remove all field
wiring terminal blocks from the AV-ZS module and remove the three (3) screws securing the module to the AV-
AMP-80 amplifier. Place the new AV-ZS module over the metal hexagon spacers and reinsert and tighten the
previously removed three (3) screws. 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 AV-ZS module and
reconnect AC and battery power to the system (see figure 26).
Failure to tighten screws will defeat the protection circuitry designed to protect the modules/cards from
damage due to lightning and static electricity.
