Product Code: DS-FCP500EK


The FCP-500 Conventional Flush-mount Detectors are UL Listed, open area photoelectric smoke detectors. Use them with commercial fire protective signaling systems and household fire warning systems (see NFPA 72, the National Fire Alarm Code). The FCP-500 is available as a photoelectric smoke detector or as a multi-sensor detector with an additional carbon monoxide (CO) sensor. The detectors are ideal for areas where increased levels of dust and fibers are expected. Each type is offered in white or transparent with color inserts. The FCP-500 series smoke detectors satisfy the most demanding aesthetic requirements. Their ultra-low profile design offers flush ceiling mounting. The detectors and covers in the P versions are supplied with reversible printed color rings in 16 colors for individual color matching.Linking the optical sensors and the CO sensor results in an extremely high tolerance to unwanted alarms. Consequently, the detector can be used in places where the work carried out gives rise to small amounts of nonfire-related smoke, steam, or dust.

Optical (Smoke) Sensor (all models): The optical sensor operates according to the scattered light method. The LEDs transmit pulsed infrared light at a defined angle into the scattered light area. If a fire occurs, the light is scattered by the smoke particles and strikes the photo diodes that transform the quantity of light into a proportional electrical signal. Interference effects from daylight and commercial lighting sources are filtered out with an optical daylight filter and by using electronic filtering and rectification algorithms. The detector's various diodes (light-emitting and photo) are individually controlled by the detector's electronics. Independent signal combinations are produced that are ideal for detecting smoke, making it possible to differentiate between smoke and interference agents (insects, objects). In addition, the detector's programming checks the plausibility of the timing and correlation of sensor signals making it possible to detect errors in the analysis electronics or the LEDs.


Detection Principle:
FCP-500(-P): Scattered light measurement
FCP-500-C(-P): Combination of scattered light measurement and CO measurement

Drift Compensation:
all FCP-500 detectors: Drift compensation for smoke sensor baseline(optical sensors)
in addition, for FCP-500-C(-P): Drift compensation for CO sensor
