Activates BEFORE Intruder Gains Access!
Simple setup! Just plug into any socket and unit automatically scans area and arms after 30 seconds. Portable too -- take with you when you travel.
Uses infrasonic technology, a totally new concept in home security, to detect the subsonic air movement associated with the opening of doors and windows. Animal movement does not activate the alarm: pushing, flexing, banging, smashing or opening a window or door does.
Powerful 110 dB siren sounds for 3 minutes, then stops & rearms itself. Siren can be set to 30 second delay or switched out for an electrical device such as a lamp or radio. With adjustable sensitivity control. UL® listed.
