S22 heat detectors have a common profile with the photo and ion smoke sensors but have a low air flow resistance case made of self-extinguishing white polycarbonate
Heat Sensor
Distributed Architecture
All FC-250 modules operate independently. There is no central operating system, no central point of failure. Processing power is distributed throughout the campus, increasing system survivability, eliminating home-run wiring costs while decreasing downtime due to system maintenance.
Highly Survivable
Since NAC’s and SLC’s are grouped on the same module and events are processed locally, ALM modules will perform local operations even if network communication has been severed. Distributed modules also minimize campus-wide downtime by restricting maintenance to the local module.
The S22 heat detector uses a single thermistor to sense the air temperature at the detector position. The thermistor is connected in a resistor network, which produces a voltage output dependent on temperature.
The S22 Heat Sensor has five pre-programmed user settings that may be accessed and changed from the Harding network fire control. Further, the pre-programmed settings are utilized in establishing the automatic temperature response values in place with Day/Night sensitivity programming.
