The Door Handle Alarm detects vibration that occurs when someone touches the handle from the outside. This door alarm sounds a 110dB alarm audible up to 600 feet (185M) away to wake you while alerting the burglar - and possibly neighbors - that an intrusion has been detected.
This user-friendly and versatile security alarm includes three operating modes (off/chime/alarm), and alarm mode includes a 30-second activation delay to prevent immediate false triggering. If the doorknob is touched anytime after the initial 30-second delay, the Door Handle Alarm sounds immediately.
