Overview
The Flamefast Gas Sensor is one of the most versatile gas sensors available on the market.
With an Analogue and Relay output, as well as a selectable BACnet or Modbus interface, FGS can connect directly into most third-party controllers or can easily connect to any of the Flamefast range of gas safety systems.
In a large proportion of modern buildings, the plant room safety systems are BMS integrated, and the FGS has been designed with this in mind. It can be treated like any other field sensor, the latching facility allows direct integration with the primary safety circuit, then simply pulse the Digital Input, or reset over the network once the alarm has cleared.
The unit can also be fully configured by the Flamefast App using the USB interface, including the address, relay properties, alarm set points and LCD behaviour.

- BACnet and Modbus
- Latching function with Reset Input
- Analogue output
- Simple configuration and calibration
- Calibration and ‘End of Life’ reminders
- Mounts onto any standard single gang junction box or conduit box
