Bosch RFDL-11 Wireless Motion Detector, 35FT (11M)

The Bosch RFDL‑11 Wireless Motion Detector delivers high‑performance intrusion detection for commercial and residential applications with a wide 11 ×11 m (35 ×35 ft) coverage area. It combines passive infrared (PIR) and microwave dual‑tech sensing with intelligent signal processing (Motion Analyzer II) to reliably detect human motion while providing false‑alarm resistance to pets, drafts, insects and environmental disturbances. With pet immunity rated up to 45 kg (100 lb) it supports installations in areas with animals without frequent false alarms. The unit is powered by four user‑replaceable AA 1.5 V alkaline batteries providing up to five years of operation and includes a battery‑life‑extension mode to reduce RF transmissions in high‑traffic areas. The device features wireless RF transmission (433.42 MHz) with supervision of low‑battery, cover‑tamper and removal from mounting surface. Compact dimensions (138 × 72 × 64 mm / 5.5″ × 2.8″ × 2.5″) enable installation at standard heights of 2.0 to 2.4 m (6.5 to 7.8 ft) on walls. Designed for indoor use in conditions from –10 °C to +49 °C (14 °F to 120 °F), the RFDL‑11 integrates easily into the Bosch RADION wireless intrusion‑detection ecosystem and provides scalable wiring‑free security with long battery life and minimal maintenance.
