Why this product

  • • Magnetic Door and Window Alarm: This 2-pack of standalone magnetic contact alarms sounds a local alert when the main unit separates from its matching magnetic strip. Each unit uses a simple two-piece design for doors, windows, or similar openings. It operates without wiring, hubs, or apps.
  • • Peel-and-Stick Installation: Each alarm mounts with adhesive backing on clean, flat surfaces. No drilling or tools are required. Align the alarm body on the moving section and the magnetic strip on the frame so they meet when closed.
  • • Battery Power Requirements: Each alarm requires two AAA batteries, which are not included. The battery compartment is located on the back of the main unit. Fresh alkaline batteries are recommended for reliable operation.
  • • Manual ON/OFF Switch: A side-mounted switch lets you turn each alarm on or off as needed. Set it to off before opening a monitored door or window for extended periods. This provides simple manual control without extra devices.
  • • Compact Unit Dimensions: The main alarm body measures approximately 3.5 inches tall by 1 inch wide by 0.5 inch deep. The separate magnetic strip is about 2 inches long. Both pieces have rounded white plastic housings for discreet placement.
  • • How the Alarm Triggers: The alarm activates when the main unit and magnetic strip separate by roughly 0.39 inches or more. This triggers a 90 dB audible alert from the built-in sounder. Close the opening to silence it after testing.
  • • Two-Alarm Value Pack: The package contains two complete alarm units, each with its own magnetic contact piece. This allows coverage of two separate entry points. Batteries and mounting hardware beyond the adhesive are not included.
  • • Indoor Use and Surfaces: These alarms are designed for indoor doors, windows, cabinets, and similar flat surfaces. They work best on clean, dry, smooth materials where the adhesive can bond properly. Outdoor or wet locations are not supported.

Description

Notice When an Entry Point Opens

When you want a simple alert for an exterior door, window, cabinet, or other opening, this door window alarm provides local audible awareness. Each unit uses a two-piece magnetic contact: one alarm body and one separate magnetic strip. When the pieces separate as the protected opening moves, the alarm sounds without a connecting wire or monitoring hub.

Two Alarms for Separate Openings

The door alarm 2 pack includes two alarm units and two corresponding magnetic contact pieces, giving you separate coverage for two suitable openings. Use them across doors, windows, cabinets, drawers, refrigerators, freezers, offices, or storage areas where the alarm body and magnetic piece can align when closed.

Peel-and-Stick Mounting

An adhesive door alarm offers tool-free placement on a clean, flat mounting surface, making it useful where drilling or wiring is not desired. The white housing has adhesive backing, while the main unit and magnetic strip mount on adjacent surfaces so they remain together when the opening is closed. This arrangement suits rental properties, small offices, and other indoor locations where a straightforward entry point alarm is preferred.

Simple Local Alerting

A wireless door alarm keeps the alert mechanism at the protected opening instead of relying on a separate receiver, app, or central hub. The standalone design is intended for immediate local sound when the magnetic contact separates. It is a practical layer of household awareness, but it is not a remotely monitored security system or emergency notification device.

Battery-Powered and User Controlled

Each alarm has a compartment for two AAA batteries, and the batteries are not included. A side ON/OFF switch lets you control whether the unit is active, while visible metal spring contacts hold the batteries inside the compartment. This battery operated door alarm continues to use local power rather than a hardwired connection.

Compact White Housing

The main alarm body measures approximately 3.5 inches high, 1 inch wide, and 0.5 inch deep, with a vertically elongated rounded-rectangle shape. The separate magnetic piece is approximately 2 inches long and 0.5 inch wide, though its depth is not specified. A large circular front sounder area, rounded edges, molded diagonal grip ridges, and a black side switch give the white unit a functional residential appearance.

For Everyday Entry Awareness

Use this window security alarm or magnetic door alarm wherever a suitable flat indoor mounting surface allows the two pieces to align. It can support awareness around exterior doors, windows, cabinets, drawers, garages, offices, RVs, and similar opening panels. The product may also provide an audible child or pet exit alert, but it should not replace supervision, restraints, or a complete security system. Keep the intended use focused on straightforward local protection and entry awareness.
