Frequently Asked Questions

Q: How does the wireless door and window magnetic alarm sensor work?

A: The sensor consists of two magnetic components — one mounted on the door or window frame and one on the door or window itself. When the two parts separate (i.e., the door or window is opened), the magnetic connection is broken and the 130dB alarm is triggered immediately, alerting you to potential unauthorized entry.

Q: Do I need any tools or wiring to install this door window alarm sensor?

A: No tools or wiring are needed. The sensor attaches easily using the included adhesive backing, making it a true DIY installation. Simply peel, stick, and you're protected. It's battery-powered and completely wireless.

Q: Where can I use this wireless magnetic burglar alarm sensor?

A: This versatile sensor works on virtually any entry point — front doors, back doors, patio or sliding glass doors, bedroom windows, basement windows, and even cabinets or drawers where you want an extra layer of security.
