Essential Info

Install this sensor into any door or window that is a direct access point into your home. Used as an accessory to the STI Burglar Stopper® Wire-Free Home Protection System, the sensor ensures every aspect of your home is safe and secure. Attach the magnet to any door or window and the transmitter to the adjoining frame. When the door or window is opened, contact in the magnet will be broken and the transmitter will immediately inform your Burglar Stopper system. The sensor is especially great for areas of your home that may not normally get much traffic, such as side doors, sheds, attics, garages, etc. Requires two AAA alkaline batteries (sold separately).
