The Mini Alert Sensor Alarm uses passive infrared technology to protect a room from intruders. It detects motion up to 30 feet away. Producing an infrared triangle, the Mini Alert creates an unseen barrier that's impossible to penetrate without setting off the alarm! When any human body approaches the detected zone, an 80db alarm siren will sound for one minute then shut-off automatically and reset itself.
Mini Alert alarm can also be set to Chime mode to greet visitors when they approach the detected zone.
Battery operated, the Mini Alert needs no wiring and can be easily moved to a new location. It has a Led low battery indicator at the front. Mounting bracket included. Requires three "AA" batteries.
