Infrared Motion Alarm with 110 dB Siren and 2 Remote Controls

A self-contained alarm for a room, entrance, shop backroom or garage: the passive infrared sensor detects movement and sounds a 110 dB siren. Two keychain remote controls let you arm and disarm it, and it has an exit and entry time delay so you can leave or come in before it triggers. The box states a detection range of about 8 m at 110 degrees. Mount it about 2 m high, angled 10–30 degrees to the wall, away from air vents and heaters. Main unit runs on four AAA batteries (not stated as included). Package: alarm unit and 2 remote controls.
