DIP Switch Programming

Each AX-CZM module has four DIP switch settings for programming module functionalities. The AX-CZM module

can be setup as eight (8) Class B or four (4) Class A conventional zones, configured for local earth/ground fault

monitoring, if the host panel's power supply does not provide earth/ground fault detection capabilities, and can be

configured for either 3.9K, 4.7K or 6.8K Class B end-of-line (EOL) monitoring.

AX-CZM Module Default Dip Switch Settings = All OFF:

Segment 7 OFF:

Earth/ground fault monitoring is performed by host panel's power supply. If AX-CZM local

earth/ground fault monitoring is required, slide DIP switch segment 7 to the ON position.

Note: If multiple AX-CZM modules require earth/ground fault monitoring and they are receiving power from

a common power supply source only one (1) of the AX-CZM modules should be set to AX-CZM local

earth/ground fault monitoring.

monitoring the earth/ground fault reference impedance is 75K.

Segment 6 OFF:

Class B wiring for all conventional zones. If Class A wiring is required, slide DIP switch

segment 6 to the ON position.

Segment 3 – 5 OFF:

Unused dip switch segments, position has no relevance, leave in the OFF position.

Segment 1 – 2 OFF:

Class B end-of-line (EOL) value 6.8K. If a 4.7K or 3.9K Class B end-of-line is required, set

DIP switch 1 and 2 as indicated below:

In addition, if an AX-CZM module is performing earth/ground fault
