The S21 Ion Sensor offers faster response times for hot burning fires
Ion 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 S21 Ion sensor’s drift compensation is managed by the ALM3-IP. The ALM3-IP monitors the average ambient analog count being returned from each S21 detector connected to the system. Due to the accumulation of dirt and dust over time, the average ambient analog count for each detector will climb. The ALM3-IP will adjust the specific detector’s alarm threshold proportionately to compensate for the rise in the average ambient count. This keeps the detectors sensing window open to the factory set tolerances established when new.
