Wireless Door Alarm

The Wireless Door Alarm adds reliable security to any single exit or entrance door. The alarm simply installs on the upper corner of an interior door.

You may also choose a set of 10 beeps announcing the door has been opened. Features a key-operated On/Off switch to allow access and silence the alarm. Battery operated with a long-life 9-VDC alkaline battery. Easy to install and program, this highly visible and compact unit is an inexpensive, yet effective security device.
