The Bosch DS150i is a surface-mount Passive Infrared detector designed for request-to-exit (RTE) use with access‑control systems. It delivers a 2.4 m × 3 m (8 ft × 10 ft) PIR coverage with Fresnel optics and is intended for doorway detection, mounting over a standard single‑gang box at heights up to 4 m. Powered from 12/24 V AC or DC and drawing about 35 mA, the gray enclosure supports a relay‑based output for door control, with configurable relay modes and adjustable latch times (0.25–60 s), plus options like LED enable/disable. UL and CE certified, the DS150i is part of Bosch's DS150i series and typically carries a 3‑year warranty.
