2.4.5 AX-CZM Host Panel Monitoring Wiring

1. Wire the host panel monitoring inputs to the Alarm and Trouble contacts of the AX-CZM module.

2. If AX-CZM local earth/ground fault monitoring is required, wire the host panel earth/ground fault

monitoring input to the Ground Fault Contact of the AX-CZM module (see figure 12).

The AX-CZM module has three (3) Form C relay contacts (Alarm, Trouble and

Earth/Ground Fault), for host panel monitoring of the AX-CZM module status.

These three relays are global to all conventional zones on the AX-CZM module, so

while an alarm or trouble can be reported, it cannot be determined which of the

conventional zones is active. For this reason, it is recommended that all AX-CZM

module conventional zones be associated with the same physical detection area.

Note: If supervision of the AX-CZM module status relay contacts is not made by the HOST fire alarm

control panel, Host panel and the interface wiring must be installed in conduit, within the same room and

no further than 20 feet away from the AX-CZM module.
