This is the perfect device to scare off someone who opens your desk dresser file cabinet lunch box etc. Simply turn the arming switch to the on position. You have a couple of seconds to put your Secret Alarm in a desk and close the drawer. The next time someone opens it a loud obnoxious noise comes from the horn until unit is reset.

Uses sensitive CDS and SCR circuit to respond to light. As long as it is kept in the dark it is quiet but when light hits the sensor WATCH OUT!
