B-1S miniature hermetic surface mount reed detector
The B-1S is a miniature hermetic magnetic detector designed to detect the opening of doors, windows and other openings. The detector is surface-mounted by gluing it to the ground or attaching it with miniature nails.
- Miniature hermetic housing with dimensions of 17 x 8 x 4 mm
- Designed for surface mounting (glued or nailed)
- Perimeter protection for doors, windows and other elements
- Detector type NC (normally closed)
- Wide operating temperature range from -10 to +55 °C
Application and mounting method
The B-1S magnetic detector is designed to signal the opening of elements such as doors or windows in burglary and assault signaling systems. Thanks to the miniature housing dimensions of both the reed switch and the magnet (17 x 8 x 4 mm), it can be used in places with limited installation space, providing discreet perimeter protection.
The device is surface-mounted - the components can be glued to the substrate or attached using miniature nails. Such a solution facilitates installation in various types of door and window frames, without milling or interfering with the design of the protected element.
Structural and environmental characteristics
The B-1S has a hermetic housing, which is conducive to stable operation in diverse environmental conditions. The detector meets the requirements of environmental class II according to EN 50130-5, which means that it can be used in typical indoor conditions where temperature and humidity changes occur within the limits of the specification.
The operating temperature range of the detector is -10 to +55 °C, and the maximum relative humidity reaches 93 ± 3%. Such parameters allow the device to be used in most standard rooms of residential, office and commercial buildings, while meeting the manufacturer's requirements.
Electrical and operational parameters
The B-1S detector is of NC type, which means that in the resting state the contacts are closed, and the opening of the protected element causes them to open and change the state in the alarm system. The properties of the reed switch, such as maximum voltage and switching current, have been selected to work with typical control panels and modules of alarm systems.
The closing and opening distances of the reed switch contacts specified in the technical data (10 mm and 12 mm) determine the required mounting geometry between the detector and magnet. The cable length of 450 mm makes it easy to bring the wiring to the appropriate installation boxes or system terminal strips.
