B-2 magnetic recessed hermetic detector
The B-2 magnetic detector is a small, hermetic reed front detector designed to be recessed into the leaf and frame of doors or windows. When properly installed, it is invisible from the outside and is available in white or brown colors.
- Magnetic detector for perimeter protection of doors and windows
- Recessed installation in the leaf and frame
- Hermetic housing
- Detector type (outside magnetic field): NO
- Available in two color versions: white and brown
Application and characteristics of the B-2 detector
Magnetic detectors are a basic element of perimeter protection, and their standard task is to detect the opening of doors and windows. The B-2 model, with its recessed mounting in the leaf and frame, allows discreet installation without interfering with the aesthetics of the premises. The hermetic design of the housing is conducive to using the detector in places exposed to increased humidity and variable environmental conditions within the limits specified by the manufacturer.
Thanks to the precisely defined closing and opening distances of the reed relay contacts, the B-2 detector ensures repeatable and predictable operation in burglary and assault signaling systems. The low weight and compact dimensions of the magnet and reed switch housing facilitate installation in typical door and window profiles, according to installation requirements.
Operating conditions and design features
The B-2 detector operates in a wide range of operating temperatures and at high permissible humidity, which allows it to be used in diverse environments. Environmental class according to EN50130-5 II defines the conditions under which the device maintains its declared parameters, which is important when designing professional SSWiN systems. The hermetic housing and NO off-field type of operation are adapted to the standard requirements used in alarm installations.
