The FG920 is a state-of-the-art stand-alone flammable gas detector built around a renowned Japanese FIGARO semiconductor sensor, offering continuous and precise monitoring of natural gas (methane) and propane. Compliant with EN50194 standards, it is powered directly from mains AC supply — no battery required for circuit control — making it a reliable, low-maintenance solution for residential, commercial, and hospitality applications.

Accurate Detection, Rapid Response
A microprocessor-controlled design ensures consistent sensitivity and performance stability throughout the detector’s life. The FG920-N detects methane (natural gas) while the FG920-L detects propane, both sounding a loud alarm exceeding 85 dB at 10ft when dangerous gas levels are detected. A test button allows alarm verification at any time.

Networkable for Wider Protection
Up to 11 additional FG920 detectors can be interconnected — if any unit detects gas, all interconnected detectors simultaneously switch to alarm mode, providing coordinated building-wide alerting. Selected models include a NO/NC selectable relay output for integration with third-party systems.
