Description
The Conventional Initiating Zone Module (FRRU004-CIZM4) is used to supervise the status of conventional initiating devices connected on an
Initiating device circuit (IDC). The FRRU004-CIZM4 detects an alarm condition and reports to the Fire Alarm Control Panel (FACP). The
FRRU004-CIZM4 module also supervises the initiating device wiring (A+, A-, B+, and B- wires) and wiring for the power supply connected toterminals 24+ and 24- to detect an open circuit. IDC wiring style is applicable to the NFPA Class B (Style B) & Class A (Style D). When theFRRU004-CIZM4 module detects an alarm, the module is latched until the system reset. When the FRRU004-CIZM4 module is used with ClassA (Style D) wiring condition and detects an open circuit on wiring of the IDC and power supply connected to terminal 24+ and 24-, the module isalso latched until the system reset.
The FRRU004-CIZM4 module has one red LED for local indication of the statuses of module itself and its wiring. Normal conditions are indicatedby flashing LED. Alarm condition is indicated by constant illumination. Open circuit condition is indicated by extinction.

Setting the Address
Each addressable module, smoke detector, heat detector and combination detector must have the address set before connecting the device tothe Signaling Line Circuit (SLC) loop. The address is set using the hand held device programmer or the addressing feature on the control panel.
