B-2T BR magnetic reed detector for recessed mounting
The B-2T BR magnetic reed detector is a medium-sized reed front detector designed for perimeter protection of doors and windows. The device is recessed-mounted into the sash and frame, so it remains invisible from the outside after installation.
- Medium-sized reed detector for doors and windows
- Recessed mounting into the sash and frame
- Equipped with screw terminals (bolted)
- Available in white and brown color versions
- Adapted to work in a wide range of temperatures and humidity
Application and function of the B-2T BR detector
The B-2T BR magnetic detector is a basic component of a perimeter security system designed to detect the opening of doors and windows. Using a reed switch and a matching magnet, it can reliably signal a violation when the leaf is moved away from the frame beyond a certain distance.
Thanks to its installation inside the joinery structure, the detector is not visible from the outside, which improves the aesthetics of the installation and makes it difficult for outsiders to locate it. Model B-2T BR is used both in burglary and robbery alarm systems and in simple opening control installations.
Construction and installation
The housing of the reed switch and the magnet housing have compact dimensions, which facilitates the drilling of holes and precise installation in door or window elements. The manufacturer has provided for mounting the detector in a face-mounted version, recessed into the sash and frame, using screw terminals for wiring.
The B-2T BR model is available in two color variants - white and brown - to better match the type and color of woodwork. The detector has specific tripping distances (contact closure and opening), which should be taken into account when arranging the elements during installation.
