FCP-500 Conventional Flush-mount Smoke
Detectors
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.
Functions
Sensor Technology and Signal Processing
All detectors in the FCP-500 series are equipped with
two optical sensors and a contamination sensor. The
FCP-500-C multi-sensor detector also has a CO sensor.
All sensor signals are constantly analyzed by the internal
signal electronics and are linked with each other through
specially developed algorithms.
▶ Modern, ultra-low profile design
▶ Color inserts match the surrounding decor
▶ Smooth, easily-cleaned detector surface
▶ Innovative retention mechanism
▶ High reliability
▶ Four-wire technology
▶ Compatible with 12 VDC or 24 VDC systems
▶ 30 ft (9 m) spacing between detectors
▶ Optional carbon monoxide (CO) sensor for false
alarm reduction
▶ Dual color LED
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.
