The Defender Mini and Chime Alarm is a popular home security device that identifies when a door or window has been opened.

Clever intruder alarm which uses a magnetic contact to welcome visitors or to shock and deter intruders.

Once the window or door opens, the magnetic field is broken and the 120dBs alarm or welcome chime will be activated.

Comes with a built-in low battery indicator.

Ideal for use on windows, doors, cupboards, and sheds to help stop sneak in burglary, or to alert you to visitors.

Can also be used as a shop door opening alert, so you never miss that customer again.
