UltraPro Battery Operated Magnetic Window or Door Alarm, 4 Pack, White

UltraPro Audible Window and Door Alarms — Simple Home Security Alert System

The UltraPro Audible Window and Door Alarms deliver an easy, cost-effective way to monitor entry points and deter unwanted access. Designed for homes, apartments, dorm rooms, offices, RVs and campers, each alarm emits a powerful 120-decibel alert that helps discourage intruders the moment a door or window is opened.

Installation is fast and wire-free. Use the included double-sided tape to mount the alarm and magnet in minutes, with no tools required. When the door or window separates the base from the magnet, the alarm activates instantly. An easy-access chime/OFF/alarm switch lets you choose a gentle chime for daily monitoring or a loud siren for security situations.

Beyond doors and windows, these compact alarms work well on cabinets, drawers and interior spaces where awareness matters. An LED indicator alerts you when battery power is low, while four included LR44 batteries ensure out-of-the-box operation. With straightforward setup and dependable performance, UltraPro Audible Window and Door Alarms provide peace of mind without complicated installations or ongoing costs.
