Combined optical/chemical detector FCP‑320 FCP-OC320-R470 Bosch

FCP-OC320-R470 Detector

The FCP-OC320-R470 is a conventional multi-sensor optical/chemical fire detector manufactured by Bosch, combining two detection principles: optical sensors (for smoke detection) and chemical sensors (for gas detection). All sensor signals are continuously analyzed by the evaluation electronics system, enabling early detection of fire hazards and minimizing false alarms.

Key Features

• 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
