The Defender Shock/Contact Alarm is a highly popular dual-function alarm that triggers a powerful siren when vibration is detected, or when a door/window is opened and the magnetic field is separated.

The vibration function can be disabled so the unit will only trigger when the door/window opens.

The shed alarm uses a 4 digit code and comes with an adhesive pad and screws for easy installation.

The unit also comes with a small solar panel that can extend battery life by up to 18 months. Not suitable for external use.

Powerful 130dBs siren to protect against forced entry and sneak-in attempts.
