Figure1.1: 500 Series Fire Detector

With their low profile design, flush‑mounted installation and possibilities for color toning, the

fire detectors in the 500 series open up a new dimension with respect to aesthetic and

functional demands.

The cooperation of engineers and designers has created the timeless, innovative design of this

detector, which integrates pleasantly into the ceiling. The detectors with associated trim ring

are available in the versions white and transparent with color toning inserts. Through the use

of the supplied color toning inserts, optimum adjustment to many different environments

becomes possible.

The lack of an optical labyrinth and their easily-cleaned smooth surface means the detectors

are also suitable for applications in high-dust areas.

The low profile, flush-mounted design allows the use the detectors even in areas that must be

free of protrusions.

Thanks to the geometric arrangement of two separate optical sensor systems, the detectors

are not sensitive to interference, such as that caused by insects. The scattered light volume

that is evaluated by the sensors is located in the free space a few centimeters below the

ceiling.

The contamination level is measured constantly. Contamination of the detector surface leads

to an active adjustment of the threshold (drift compensation).

The detector is available as a scattered light fire detector only or as a multisensor detector

with an additional gas sensor.

The combination of scattered light detector and gas sensor allows the evaluation of signals

with the help of modern signal processing methods. The result is high immunity against

deceptive alarms and extended application possibilities in environments that are not suitable

for pure scattered light smoke detectors.

The FCP‑500 series are conventional technology detectors. Due to their current consumption,

a four-wire connection is required. Thus, they can be operated with numerous different fire

panels.

Accessories

The 500 Series Detectors are generally mounted flush with the ceiling in false ceilings. The

detector and base are installed in a robust ceiling mount back box. In addition, a housing for

mounting within concrete ceilings can be used.

For special applications where recessed ceiling mounting is not possible, a surface mount

back box is available. This is used as an alternative to the ceiling mount back box.

The surface mount back box with damp room seal also allows the detector to be used in a

humid environment.

All bases have an integrated strain relief for false ceiling cables.

The connection terminals are easily accessible. Cables up to 3.3 mm2 in cross section can be

used.

An innovative concept for locking the detector module utilizing the push‑in/push‑out principle

allows very quick and easy insertion and exchange of the click and lock detector.

For the detector test and detector exchange, a special user-friendly service accessory is

available.

per second).

– Can be connected to the LSN fire panels FPA‑1200, FPA‑5000 (both with CZM module or

4CON module on LSN loop), UEZ2000 LSN, UGM2020 and to other fire panels or their

receiver modules with identical connection conditions.

– EN54‑7 certified.

1.2 System Description

All detectors in the 500 Series are equipped with two optical sensors and a pollution sensor.

The FCP‑OC500 Multisensor Detector contains a gas sensor as an additional detection

channel.

All sensor signals are analyzed continually by the internal signal evaluation processor and are

linked with each other by specially developed algorithms.

By linking the optical sensors and the gas sensor, the OC detector can also be used in places

where the work carried out gives rise to small amounts of smoke, steam or dust. The alarm

will only be triggered automatically if the signal combination corresponds with the detector’s

programmed characteristic diagram. Consequently, an extremely high tolerance to unwanted

alarms is achieved.

3 Transmitter (LEDs) 7 Measuring area

4 CO sensor (only OC-variants)

1.4 Functional Description of the Sensor Technology

Optical sensor (smoke sensor)

The optical sensor (refer to Configuration of the Detector (1)) operates according to the

scattered light principle.

The LEDs (refer to Configuration of the Detector (3)) transmit light at a defined angle into the

measuring area (refer to Configuration of the Detector (7)). In case of fire, the light is

scattered by the smoke particles and strikes the photo diodes (refer to Configuration of the

Detector (2)), which transform the quantity of light into a proportional electrical signal.

The effects of daylight and commercial lighting sources are filtered out with an optical daylight

filter and by the use of electronic filtering and phase-locked rectification (ambient light

stability: dazzling test EN54‑7).

The various light-emitting and photo diodes of the detector are individually activated.

Consequently, signal combinations are produced that are independent of each other and

ideally suitable for the detection of smoke, which makes it possible to differentiate between

smoke and interference agents (insects, objects). In addition, the time characteristics and the

correlation of the optical sensor signals for the fire or interference detection are evaluated.

Moreover, plausibility checking of the various signals makes it possible to detect errors in the

evaluation electronics and the LEDs.

2019.11 | 5.0 | F.01U.003.962 Operation Guide Bosch Sicherheitssysteme GmbH

Chemical sensor (CO gas sensor)

The gas sensor (refer to Configuration of the Detector (4), only FCP‑OC500(-P)) detects

mainly the carbon monoxide (CO) that is produced by a fire, but it also detects hydrogen (H)

and nitrogen monoxide (NO).

The basic measuring principle is CO oxidation on an electrode and the measurable current

that arises from this. The sensor signal value is proportional to the concentration of gas.

The gas sensor supplies additional information in order to reliably suppress the disturbance

variables.

Pollution sensor

The contamination level of the detector surface is measured and evaluated continuously by the

pollution sensor (refer to Configuration of the Detector (6)).

1.5 LED Operation

The two-color LED of the detector indicates the operation and alarm statuses.

During the whole life cycle, the sensors are self-monitored and the sensitivity is self-adjusted

according to the programmed threshold.

In case of an alarm, the LED turns red. The detector is set back to standby if the alarm is reset

via the fire panel and if the cause of the alarm is gone.
