Bosch FAP-520 Flush-Mounted Addressable Smoke Detectors (500/520 Series)

Product Details

Product Overview

The 520 Series are ultra-flat, flush-mounted automatic fire detectors for Bosch LSN improved loops. They sense smoke by scattered light in a virtual chamber just below the detector face, and the OC versions add a combustion-gas sensor. Conventional 500 Series versions exist, and -P versions take colour rings to match the ceiling.
