Non-Addressable zone monitor module
MI-DCZRME
The MI-DCZRM is used to link a zone of conventional devices to an intelligent system controlled by an addressable panel. The CZR has a resistor built in, making it especially suitable for connection to a conventional zone that operates in a hazardous area requiring intrinsically safe equipment.
• Connection of a zone of non-addressable detectors to an analogue addressable fire system
• Built in isolation allowing system installation in stages without loss of protection
• Monitors open circuit and short circuit faults
• TRI-Colour Status LED
• Zone powered from addressable loop wiring or external 24V PSU
• Remote reset of non-addressable zone
• Monitoring of external power supply
• External fault input
• CPD approval to EN54-17 and EN54-18, LPCB and VdS
• DIN rail mountable, consistent with all other modules
• Support for an extended power supply range as low as 18Vdc 60mA with an External PSU
