1 Fire Alarm Systems FCP 32/FCH 32 Conventional Automatic Fire Detectors FCP 32/FCH 32 Conventional Automatic Fire Detectors High reliability of detection thanks to evaluation electronics Active adjustment of the threshold (drift compensation) if the optical sensor becomes dirty Activation of a remote external detector alarm display possible Mechanical removal lock (can be activated/deactivated) Dust-repellent labyrinth and cap construction The FCP 32/FCH 32 Series Conventional Automatic Fire Detectors set new standards in fire detection technology through a combination of optical, thermal and chemical (gas) sensors and intelligent evaluation electronics. Their most impressive feature is their ability to prevent false alarms, as well as speed and accuracy of detection. The enhanced operating voltage range of 8,5 V DC up to 3 V DC and the two variants with 82 Ω alarm resistor or 47 Ω alarm resistor enables the detector application with nearly all conventional fire panels. System overview Operating mode OC32 OT32 O32 FCH- T32/ T32- FSA Combined x x - - Optical (scattered light measurement) x x x - Thermal max. - x - x Thermal differential - x - x Chemical (gas measurement) Functions x The OC32 and OT32 Multisensor Detectors each combine two detection principles. All sensor signals are analyzed continually by the internal evaluation electronics and are linked with each other. If a signal combination fits the detector's programmed code field, an alarm is automatically triggered. By linking the sensors, the combined detectors can also be used in places where work carried out gives rise to light smoke, steam or dust. Optical sensor (smoke sensor) The optical sensor uses the scattered-light method. An LED transmits light to the measuring chamber, where it is absorbed by the labyrinth structure. In the event of a fire, smoke enters the measuring chamber and the smoke particles scatter the light from the LED. The amount of light hitting the photo diode is converted into a proportional electrical signal.

2 2 FCP 32/FCH 32 Conventional Automatic Fire Detectors Thermal sensor (temperature sensor) A thermistor in a resistance network is used as a thermal sensor; an analog-digital converter measures the temperature-dependent voltage at regular intervals. When the maximum temperature of 54 C is exceeded (thermal maximum), or if the temperature rises by a defined amount within a specified time (thermal differential), the temperature sensor triggers the alarm status. Chemical sensor (CO gas sensor) The main function of the gas sensor is to detect carbon monoxide (CO) generated as a result of a fire, but it will also detect hydrogen (H) and nitrous monoxide (NO). The sensor signal value is proportional to the concentration of gas. The gas sensor delivers additional information to effectively suppress deceptive values. Depending on the service life of the gas sensor, the OC 31 detector switches off the C sensors after five years of operation. The detector will continue to function as an O detector. The detector should then be exchanged immediately in order to be able to keep using the higher reliability of detection of the OC detector.

Maximum cable length: 1 m, for J- Y(St) Y n x 2 x.6/.8 Country-specific standards and guidelines must be observed during the planning phase. The detector can be painted (cap and base) and thereby adapted to the surrounding colour scheme. Note the information in the Painting Instructions (Document Number F.1U ). Installation/configuration notes in accordance with /VDE/DIBt Planning for multisensor detectors follows the guidelines for optical detectors, unless a specific planning guideline is available (see DIN VDE 833 Part 2 and VDS 295). The OC and OT types are planned using the guidelines for optical detectors if operated as optical detectors or as combined detectors; see DIN VDE 833 Part 2 and VDS 295. When planning fire barriers according to DIBt, you have to use the FCH-T32-FSA. This detector has the characteristic curve corresponds to class A1R. Parts included Q t y.
