Wireless Magnetic Door and Window Sensor

Product description

Door and window alarms are an integral part of any security system. Without them, your alarm system can’t tell if your windows and doors are open or closed. Contact sensors monitor external access points so your alarm system can react if someone tries to gain access to your property by prying open a door or climbing through an unlocked window.

When SECOM’s door and window sensor detects activity, it remotely alerts keyholders via the SECOM Smart Security app and notifies our 24-hour monitoring centre.

Frequently Asked Questions

How does a magnetic contact work?

Window and door sensors work using magnets. The sensor inside the device has an internal switch that closes when it is near a magnet. When an intruder opens a window or door, the magnet is separated from the sensor, releasing the switch and triggering the alarm.

How long does the battery last?

The SECOM wireless magnetic contact is there to provide discreet, long-lasting protection. The high-quality lithium battery lasts up to 6 years with normal use.
