Why choose our door and window alarm?

Powerful 90 dB audible alarm

When an opening is detected, the device triggers an audible alert rated at 90 dB.

This signal draws the attention of people nearby and quickly alerts you to an opening.

Automatic magnetic detection

Thanks to its magnetic sensor, the alarm detects the separation between the two components installed on the door or window.

When the components move apart as the door or window opens, the system can trigger its audible alert.

Quick, wire-free installation

No need to run cables or modify your electrical system.

The product is designed to be installed using its adhesive system on a suitable, clean, and dry surface.

Battery-powered operation

The alarm operates using button cell batteries, with no connection to the electrical grid.

This allows you to place it in different areas of your home, depending on your needs.

Compact and discreet design

With its small size and white finish, it blends easily into many interiors.

An affordable solution

Enjoy a local alert device with no monthly subscription or professional installation required.

Simple, affordable, and practical additional protection for everyday use.

A simple and effective detection system

The alarm works using two complementary components: a main unit and a magnetic contact.

Step 1 — Installation

Attach the main unit to the frame or moving part of the door or window, then position the magnetic component opposite it.

Step 2 — Activation

Install the required batteries and activate the device according to the manufacturer's instructions.

Step 3 — Monitoring the opening

When the door or window is closed, the two components remain close to each other.

Step 4 — Audible alert

When an opening causes them to separate, the sensor detects the change in position and triggers the audible alert according to the device's operating mode.

Step 5 — Resetting

Close the door or window again and use the controls provided by the manufacturer to stop or reset the alarm.

Hassle-free operation

The device's battery-powered operation requires no Wi-Fi connection or alarm control panel to produce a local audible alert.
