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 BACnet MS/TP 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 BACnet network once the alarm has cleared. This negates the requirement for a controller, cutting down cost of the equipment and installation.
The broadband Pellistor and Infra-red Hydro-carbon sensors can be calibrated to suit most combustible gases with the option to factory callibrate and rename the sensor for the specific gas. Flamefast can also offer a full range of toxic gas sensors, including H2S, HCN and many more (please contact for details).
