B-2S miniature hermetic recessed magnetic detector
B-2S is a miniature hermetic reed detector designed for perimeter protection of doors and windows. The detector is recessed-mounted into the sash and frame, so it remains invisible from the outside after installation.
- Miniature hermetic reed detector for perimeter protection
- Flush mounting into the sash and frame of the door or window
- Small hermetic housing with a diameter of 6.5 mm
- Operating temperature range from -10 to +55 °C
- Available in white and brown color versions
Application and mounting method
The B-2S detector is designed for use in intrusion alarm systems as a perimeter protection element to detect the opening of doors and windows. Thanks to recessed mounting in the leaf and frame, the detector's elements are hidden, which improves the aesthetics of the installation and makes it difficult for unauthorized persons to locate it.
The frontal design and compact dimensions of the reed switch and magnet housing allow the detector to be used in profiles with limited installation space. The cable length of 450 mm makes it easy to lead the signal to a control panel or other surveillance device.
Operating characteristics and environmental conditions
The B-2S detector operates in environmental class II according to EN50130-5, which defines its resistance to typical conditions expLoatation indoors. The hermetic housing and the allowable maximum humidity of 93 ±3% allow the device to be used in environments with increased humidity, as required by the standard.
The operating temperature range of -10 to +55 °C allows the detector to be used in a wide range of temperature conditions. The specified closing and opening distances of the reed switch contacts (25 mm and 33 mm, respectively) determine the required cooperation between the reed switch element and the magnet during installation and expLoatation.
