The FSA-410 (four- wire) photoelectric smoke detectors incorporate a low-profile design and features that help reduce false alarms and provide consistent smoke detection. Both smoke detectors offer a built-in alarm horn, integral dualsensor heat detection, automatic drift compensation and an easy-maintenance removable chamber. The FSA-210/410 are listed for commercial and residential applications, and are compatible with all DSC control panels. Precise and quick sensitivity testing is easily accomplished with the new FSD-100 handheld test meter.
False Alarm Reduction
DSC is committed to reducing false alarms and has integrated a number of features into the FSA-210/410 to provide reliable detection. One important feature is drift compensation, which provides a constant level of sensitivity performance for extended operation. As dust accumulates in a detector this feature adjusts to maintain the original factory-set sensitivity, thereby minimizing the potential for false alarms. If the detector reaches its limit of compensation, it will indicate a trouble condition well before the sensitivity increases to a level where false alarms will be generated.
The FSA-210/410 smoke detectors with integral horns can be interconnected with the PRM-2W (two-wire) or PRM-4W (four-wire) polarity reversal modules. Mounted inside the control panel or externally in its own plastic enclosure, the PRM-2W/4W, upon initiation of a fire alarm, receives a signal from the control panel to reverse the voltage polarity to the smoke detector. By reversing the polarity, the integral horns of all interconnected smoke detectors will sound. All horns will remain synchronized in the temporal pattern for a minimum of three minutes.
Non-Contact Sensitivity Testing
Precise and quick sensitivity testing is easily accomplished with the noncontact FSD-100 handheld test meter. Powered by a standard 9 V alkaline battery and small enough to fit inside a shirt pocket, the FSD-100 holds 500 readings that can be downloaded to any computer. To initiate a reading, a technician simply holds the FSD-100 near a DSC smoke detector and activates the detector's test button.
