Wireless Reed Switches

Wireless Reed Switches – Smart Door & Window Contacts for Security Alarm Systems

Explore our range of wireless reed switches at CTC Communications, designed to provide reliable door and window protection without the need for cabling back to the main alarm panel. Wireless reed switches communicate through a compatible wireless receiver, making them ideal for alarm upgrades, retrofits and installations where running wires is difficult or impractical.

Used in both home and business security systems, reed switches help create an important first layer of perimeter protection. When a protected door or window is opened and the magnetic contact separates, the reed switch sends a signal to the alarm panel to trigger an alert or alarm event.

What Are Wireless Reed Switches?

Wireless reed switches are security alarm sensors designed to monitor the opening and closing of doors, windows and other access points. Unlike wired reed switches, they do not require physical cabling back to the control panel.

These devices communicate wirelessly to the alarm system through a compatible receiver, helping simplify installation while still delivering effective perimeter security.

How Wireless Reed Switches Work

A reed switch is paired with a magnet and installed on a door or window frame. When the door or window is closed, the magnet keeps the reed switch circuit secure. Once the door or window opens and the magnet separates, the sensor sends a signal to the alarm panel.

  • Flush mount reed switches – Installed neatly within the frame for a more concealed finish
  • Surface mount reed switches – Mounted on the surface of the frame for easier installation

Why Professional Installers Always Prioritise Reed Switches

In professionally designed alarm systems, reed switches are not optional — they are essential. Motion detectors react after movement occurs, but magnetic contacts detect intrusion at the point of entry. Proper perimeter protection using high-quality reed switches significantly reduces false alarms and improves overall system reliability.
