Easy to Setup and Ready to Go
The Garage / Shed Wired Door & Window Alarm is a standalone magnetic break contact alarm with built-in siren. The alarm has a programmable 3 digit security PIN to deactivate the alarm and an entrance and exit delay to give you the time to arm and disarm it. Easy and quick setup as the contact alarm is battery operated (batteries not included) with a 0.18 m cable to the magnetic contacts for added flexibility.

Where should I place my alarm?
The Garage / Shed Wired Door & Window Alarm can be placed up to 0.18 m away from the entrance or exit you want to alarm. The alarm can be used as either an intruder alarm or in chime mode to account for visitors. The alarm panel also contains a panic function immediately setting off the alarm in an emergency and an over-ride function if the door needs to be left open.

By default, the timer to disrm the alarm is set to three seconds, but can be adjusted to 15 or 30 seconds if required.
