Fire Alarm Systems | 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.

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.
