Overview
The Flamefast Duct Mounted Gas Detector provides a robust, cost effective solution for gas monitoring in ductwork.
The BACnet MS/TP interface can be used with any of the Flamefast range of safety systems, or can be connected directly to the BMS, and provides an unrivalled level of information.
Although the sensors can be connected to third party BACnet networks, for safety systems it is strongly recommended that the sensors are used in conjunction with a Flamefast BoilerGuard or GasMonitor.
The broadband Pellistor and Infra-red Hydro-carbon sensors can be calibrated to suit most combustible gases, with the option to factory calibrate 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).
