RSD1 90dB Wireless Door & Window Alarm Sensor

Simple protection for doors and windows

The RSD1 is a compact magnetic alarm designed to provide an immediate audible warning when a protected door or window is opened. With no wiring required, it is a practical security upgrade for homes, apartments, offices, storage areas, cabinets, and other indoor entry points.

Loud 90dB local alarm

The alarm unit and magnetic contact are installed on the two sides of a door or window frame. When the entry point opens and the magnet moves away from the sensor, the unit produces a loud 90dB alert to draw attention and help deter unauthorized entry.

• 90dB alarm: clear local warning for doors and windows.

• Magnetic detection: responds automatically when the protected entry point opens.

• Battery powered: runs on two 1.5V AAA batteries for cable-free installation.

• Compact plastic housing: suitable for discreet indoor placement.

• Versatile use: ideal for home security, child safety, offices, cabinets, and storage spaces.

Quick installation and everyday use

Mount the alarm body and magnet so they align when the door or window is closed. Once powered, the sensor monitors separation between the two parts and sounds the alarm when the protected opening is moved. Batteries are not included, allowing the installer to select suitable cells for the application.
