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.
