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 “AlarmVerification”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.
