Module cho đầu báo thường 1 zone NOHMI FRRU004-CIZM4
– 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 to terminals 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 the FRRU004-CIZM4 module detects an alarm, the module is latched until the system reset. When the FRRU004-CIZM4 module is used with Class A (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 is also 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 indicated by flashing LED. Alarm condition is indicated by constant illumination. Open circuit condition is indicated by extinction.
Features
– One simple LED for status indication.
– NFPA Class A (Styles 6 & 7) and Class B (Style 4) for SLC.
– NFPA Class A (Style D) and Class B (Style B) for IDC.
– Electronic address setting.
– Downsized unit.
– Easy installation.
