Fireguard FG901MI3_AP 3 Input Addressable Module with short circuit isolator

The Fireguard FG901MI3_AP is an analog addressable 3-input module designed to monitor up to three independent potential-free contact circuits on a single loop address. Engineered to consolidate multiple field inputs into a single device, it simultaneously supervises three external dry-contact devices—such as water flow switches, valve tamper switches, and pressure switches—for open-circuit and short-circuit fault conditions. Its built-in short-circuit isolator automatically isolates loop wiring faults to ensure uninterrupted communication with other network devices. Featuring flexible manual or automatic addressing modes, low standby current consumption, and onboard LED indicators for clear diagnostic feedback, the EN54-compliant FG901MI3_AP offers a space-saving and cost-effective monitoring solution for Fireguard addressable fire safety systems.
