Features - Bosch FCP-320 Operation Manual

Conventional Automatic Detectors
All sensor signals are analyzed continually by the internal signal analysis 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 (combined detectors), the detector can also be used in places where
the work carried out gives rise to light smoke, steam or dust.
The FCP-OC320/FCP-OC320-R470 detectors analyze the present CO concentration and adjust
the threshold of the optical sensor in accordance with the CO concentration. If no CO is in the
air, the alarm is triggered nonetheless at a certain level of smoke density and above. However,
the alarm is not triggered if only CO is detected in the air.
The FCP-OT320/FCP-OT320-R470 detectors trigger an alarm in the case of smoke as well as in
the case of a temperature rise. Additionally, the threshold of the optical sensor is adjusted in
accordance with the absolute temperature and the rate of temperature rise.

Bosch Sicherheitssysteme GmbH
Active adjustment of the threshold (drift compensation) if the optical sensor becomes
contaminated.
Active adjustment of the threshold (drift compensation) of the chemical sensor.
Activation of a remote external detector alarm display is possible.
Optional mechanical removal safeguard (can be activated/deactivated).
Dust-resistant labyrinth and cap construction.
Every detector base has a "Chamber Maid Plug" (a cleaning opening with a plug) for
blowing out the optical chamber with compressed air (not required for the FCH-T 320/
FCH-T 320-R470/FCH-T 320-FSA Heat Detectors).
Connectable to Bosch fire panels and the majority of conventional fire panels available on
the market.
Two variants with 820 Ω alarm resistor and 470 Ω alarm resistor enables the detector
application with nearly all conventional fire panels.
An unscreened cable may be used for the primary line.
