Notifier · Fire & Life Safety

Description  The Notifier IZM-8 Initiating Zone Expander Module is an eight-zone expansion board designed to increase the detection capacity of compatible Notifier fire alarm control panels. It provides eight supervised initiating device circuits for connection to smoke detectors, heat sensors, and manual pull stations.     Technical Specifications  Condition New/Never Used Surplus Brand Notifier Category Fire Alarm Equipment Part Number IZM-8 Subcategory Initiating Zone Expander Module Module Type Zone expansion interface board Number of Zones 8 supervised initiating device circuits Device Compatibility Two- and four-wire detectors, heat sensors, pull stations Operating Voltage 24 VDC nominal Circuit Supervision End-of-line resistor supervision for open/short fault detection Communication Interface Compatible with select Notifier legacy control panels Indicators LED status indication for each zone Mounting Type Panel-mounted or internal cabinet installation Construction Fiberglass PCB with protective coating Standards Compliance UL Listed; NFPA 72 compliant (legacy) Operating Temperature Range 32°F to 120°F (0°C to 49°C) Dimensions Approx. 8" L × 5" W × 1.5" D Weight 0.9 lb (0.41 kg)     Information About IZM-8 The IZM-8 is an expansion module developed by Notifier to add additional initiating zones to select conventional and addressable fire alarm control panels. Each of its eight supervised zones supports two-wire or four-wire devices and includes end-of-line supervision for fault detection. This module enables system designers to expand detection coverage in large or multi-area facilities without replacing the main control unit. Though discontinued by the manufacturer, the IZM-8 remains a trusted and essential component for maintaining and servicing existing Notifier fire alarm systems. Key Features: Eight Initiating Circuits: Expands compatible panels with eight additional supervised input zones. Supervised Zones: Detects open, short, and ground fault conditions for each circuit. Flexible Compatibility: Works with a range of legacy Notifier fire alarm control panels. Two- or Four-Wire Device Support: Accepts standard smoke detectors, heat sensors, and manual pull stations. Compact Design: Fits within control panel enclosures or expansion bays for efficient use of space. Reliable Operation: Provides consistent signal integrity and fault isolation per zone. Durable PCB Construction: Engineered for long-term service in demanding environments. Legacy Support: Ideal for maintaining discontinued or upgraded Notifier system installations. The IZM-8 delivers the reliability and precision required for supervised zone expansion in fire alarm detection systems.
