Six-Zone Addressable Interface Module
• Six addressable Class B or three
addressable Class A initiating
device circuits.
• Removable 12 AWG (3.1 mm²) to
18 AWG (0.78 mm²) plug-in
terminal blocks.
• Status indicators for each point.
Gamewell’s CZM-SS SmartScanTM
six-zone interface module provides an interface between the intelligent alarm system and a twowire conventional detection zone. A
common SLC input is used for all
modules, and the initiating device
circuits share a common external
supervisory supply and ground. Otherwise, each module operates independently from the others.
The first module is addressed from
01 to 94 while the remaining modules are automatically assigned to
the next five higher addresses. Provisions are included for disabling a
maximum of two unused modules.
All two-wire detectors being monitored must be two-wire UL compatibility listed with the modules. The
CZM-SS transmits the status of a zone of two-wire detectors to the fire alarm
control panel. Status conditions are reported as normal, open, or alarm. The interface module supervises the zone of detectors and the connection of the external
power supply.
Each CZM-SS module has panel-controlled bicolor LED indicators. The panel can
cause the LEDs to blink, latch on, or latch off.
• Rotary address switches.
• Compatible with Gamewell’s 602,
610, 632, 654 and 658 FACPs
with SmartScan™ SLC.
• Mount one or two modules in a
BB-XP cabinet (optional).
• Mount up to six modules on a
CHS-6 chassis in a BB-25
cabinet (optional).
• Mounting hardware included.
