The Defender Window and Chime Alarm is a very popular home security device that uses magnetic field technology to identify when a door or window has been opened. The alarm comes in two parts, with the alarm activating when the two parts are separated. Ideal for use on windows, doors, cupboards and sheds to help stop sneak in burglary to your home or business. The unit can be set to emit either a powerful 110dBs alarm siren to warn of intruders, or a pleasant chime sound to announce visitors. Self adhesive for easy installation and battery powered. Recommended by Namibian Police, Local Councils and Neighborhood Watch Groups.
