B-2T - magnetic reed detector for recessed mounting
B-2T is a medium-sized wired magnetic (reed) detector for perimeter protection, designed to detect the opening of doors and windows. The detector is recessed-mounted in the leaf and frame, equipped with screw terminals and available in white and brown color versions.
- Medium-sized front reed detector for perimeter protection
- Flush mounting in the sash and frame of the door or window
- Equipped with screw terminals (bolted)
- Invisible from the outside when properly installed
- Available in white and brown versions
Application and purpose
The B-2T magnetic detector is an essential component of a building perimeter protection system for detecting the opening of doors and windows. Thanks to its NC-type reed switch design, the device cooperates with alarm control panels, signaling violation of the protected zone by changing the state of the reed switch contacts. This solution works well in burglary and assault signaling systems, where early detection of an attempt to enter the protected facility is required.
Construction and mounting
The B-2T is a recessed mount detector, installed in the leaf and frame of the door or window, which makes it invisible from the outside after installation. The housing of the reed switch and magnet has compact dimensions that allow it to be used in standard woodwork profiles. The use of screw terminals makes it easy to connect the wires and service the device. The detector meets the requirements of environmental class II according to the EN 50130-5 standard, which confirms its adaptation to typical conditions expLoatation in protected objects.
Operating conditions and parameters
The device is designed to operate in a wide range of temperatures and increased humidity, which allows the detector to be used in various environmental conditions. The specified values for the closing and opening distances of the reed switch contacts facilitate the correct design and execution of the installation to ensure stable and repeatable detection of the opening of protected elements. Electrical parameters, such as maximum switchable voltage, maximum current and load power, determine the safe conditions of cooperation of the detector with other elements of the alarm system.
