GFE IO ISO

Global Fire Equipment IO ISO Addressable Input/Output Module

Fully-monitored addressable I/O interface module that allows third-party equipment to be connected to a fire alarm control panel via normally-open dry contacts, while providing a changeover output relay to control ancillary systems.

Main Features:

• Loop powered: 17 V to 30 V DC
• Quiescent loop current: approx. 0.46 mA
• Fault condition loop current: approx. 0.79 mA
• Alarm loop current (LED illuminated): approx. 2.0 mA + 9.8 mA (with relay active)
• Relay output contact rating: 2 A @ 30 V DC (resistive) or 0.5 A @ 125 V DC
• Cable size for loop connection: up to 2.5 mm² conductors
• Ingress protection: IP43 (indoor use)
• Operating temperature: ?10 °C to +50 °C; Humidity up to 95% RH non-condensing
• Housing: ABS plastic, colour options White or Red; Flame-retardant rating UL94 V-0
• Dimensions: approx. Ø 100 mm × 48 mm (height); Weight: ~29 g (module only) / ~134 g (module + box)
• Monitoring of input contact for open-circuit or short-circuit fault conditions and alarm activation
• Onboard LEDs: Green = polling status; Yellow = output relay active; Red = alarm condition at input

Notes:

• Module address selectable via 8-way DIP switch (addresses 1-125).
• Relay output is powered from the loop — no external 24 V supply required for standard operation.
• Installation considerations: ensure loop polarity and wiring meet system specification; include module’s quiescent and potential alarm currents in loop load calculations.
• One module can interface equipment such as sprinkler flow switches, extinguishant level monitors or door-release devices to the fire alarm system.
• Professional installation is recommended to ensure compliance with EN54 system standards and proper integration with the fire panel.
