This latest addition to Notifier’s Advanced Detection line, Notifier FSC-851, combines four complementary technologies into one device to convey accurate fire sensing information for locations where absolute certainty is required. Also, it is designed for use with Notifier’s ONYX series fire alarm control panels (FACPs).
In fact, the integration of continual monitoring for all four major elements of a fire has enabled Notifier to create a detector, Notifier FSC-851, that responds more quickly to an actual fire with the highest immunity to nuisances. Besides, this advanced multi-criteria detector operates at a high immunity level, changing to become very sensitive to identify those that should be ignored, reducing false alarms.
The program changes sensor thresholds, sensor gain, time, delays, combinations, sampling rates, and averaging rates. Furthermore, if any sensor fails, the detector automatically adjusts the sensitivity of the remaining sensors. It also recognizes a fault condition.
The CO cell has an expected lifetime of approximately six years. Also, it is not a field replaceable component. In Addition, an internal timer signals the control panel to indicate the approach of the CO cell’s end of life. Upon expiration, you should contact the system supplier to arrange for replacement of the unit. Also, the algorithms automatically adjust to properly weight the inputs from the photo-electric, heat, and IR sensors.
