Description

The Conventional Zone Module CZM-4 is used with the

MXL to provide four Class A (Style D) or Class B (Style

B) conventional initiating device circuits. Each circuit can

monitor up to 30 Siemens Fire Safety two wire photo-

electric or ionization smoke detectors and an unlimited

number of normally open contact devices. Projected

Beam Detectors may also be used. The CZM-4 circuits

will support the use of Detector Relay Bases, Audible

Bases and Remote Indicator Lamps. Activation of any

device on a circuit will initiate a zone alarm condition

resulting in the operation of programmed functions. Any

circuit in the alarm or trouble condition will be identified

by a user specified 32 character alphanumeric message

displayed on the MXL LCD annunciator.

CZM-4

Conventional Zone Module

Each of the CZM-4’s circuits are designed to function in a

local “Degrade” mode during failure of the MXL main

processor or the loss of the system communication

network. While in the “Degrade” mode the CZM-4 is still

capable of reporting both alarm and trouble conditions and

activating local outputs.

Any or all of the CZM-4 circuits can be programmed to

operate with the “Alarm Verification” feature. This feature

allows the automatic verification of alarm conditions caused

by smoke detectors in order to prevent nuisance alarms.

The CZM-4 module plugs into one full slot in the MOM-2

or MOM-4 expansion card cage. Up to two CZM-4 mod-

ules may be plugged into a MOM-4 card cage.
