FCP-O320
The Bosch FCP-O320 is a conventional optical smoke detector from the FCP-320 series, using scattered-light technology where an LED transmits light into a measuring chamber, and smoke particles scatter the light to trigger detection with high reliability against false alarms.
It features active threshold adjustment (drift compensation) for optical sensor contamination, dust-resistant labyrinth design, mechanical theft lock option, and a chamber-maid plug for easy compressed air cleaning.
