Gas Alarm Controllers
Single-zone to 6-zone centralized gas alarm control - driving automatic shutoff valves across residential, commercial, and large facility installations
Select by Number of Zones
Compact single-channel controller for residential and small commercial installations. Drives one GD-series shutoff valve on gas alarm. Includes steel wall-mount bracket.
Two-zone version of the FC-531R in the same compact enclosure. Independently controls two gas detectors and two shutoff valves - ideal for dual-room monitoring or two-burner kitchen setups.
3-zone controller for restaurants, commercial kitchens, and multi-room setups. Independent relay per channel. Industrial SMPS (100-277VAC worldwide input) built in.
6-zone controller for hotels, large commercial facilities, and multi-building gas safety. Dual-column LED layout. Same SMPS and board platform as EC-533R.
From Detection to Shutoff in Seconds
The controller is the brain of the system - receiving alarm signals from detectors and triggering shutoff valves automatically.
FB-series detector senses gas above 25% LEL threshold and triggers relay output signal.
EC/FC controller receives the signal, activates buzzer, and illuminates the zone LED.
Dry-contact relay drives the GD-series shutoff valve closed within 15 seconds.
After ventilation and inspection, press RESET to restore normal operation.
