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.
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.
