The FGS Gas Sensor is one of the most cost-effective and versatile units available on the market. With a Voltage Output and Volt-Free Contact, the FGS can connect directly to most third-party controllers or easily to the new LCD-based range of panels via the BACnet output.
In most modern buildings, 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 pulse the Digital Input to reset once the alarm has cleared. This negates the need for a controller, reducing the cost of the equipment and installation.
