Magnetic Reed Switch Door/Window Sensor SATEL B-1F-BR — surface-mounted brown

Surface-mounted magnetic reed switch SATEL B-1F-BR is a compact brown sensor set designed to monitor doors and windows. The assembly consists of a main contact and a magnet, intended for installation on frames or leaves to detect opening and closing. The sensor provides a wired normally closed contact suitable for connection to alarm control panels and wired security systems, enabling perimeter control and basic intrusion detection in residential and commercial environments.

Advantages

The surface-mounted form factor allows installation without recessing into profiles, reducing installation time and preserving door or window structure. The normally closed contact offers reliable tamper-resistant signaling to control panels and helps to maintain circuit integrity if wiring is interrupted. Compact dimensions and a neutral brown finish provide discreet integration with wooden frames and darker finishes. The sensor is compatible with standard wired alarm inputs and supports straightforward wiring and maintenance procedures.

Suitable for

• Monitoring interior and exterior doors in homes and apartments
• Securing windows and balcony doors in residential properties
• Perimeter control for small offices and retail premises
• Integration with wired alarm control panels and access systems

Key specifications

• Mounting type: surface-mounted for frame or leaf installation
• Contact type: normally closed (NC) magnetic reed contact
• Color: brown suitable for wooden or dark frames
• Sensor set: main contact and separate magnet
• Connection: wired two-conductor interface for alarm inputs
• Application: door and window open/close detection for perimeter security

How to use

Mount the main contact on the door or window frame and the magnet on the moving leaf so that they align when the door or window is closed. Ensure correct orientation and maintain the specified gap between the contact and magnet to guarantee reliable switching. Connect the sensor’s wires to the alarm control panel input configured for a normally closed circuit, following the control panel manufacturer’s wiring and supervision guidelines. Test operation by opening and closing the door or window to verify alarm input state changes and make adjustments to alignment if necessary.

Usage recommendations

For reliable long-term operation, install the sensor in a dry location protected from direct water exposure and excessive mechanical stress. Use appropriate cable types and secure routing to prevent strain on the connections. When integrating with alarm systems, configure supervision where supported to detect wiring faults. Choose the brown finish to match wooden frames or darker finishes for less visible installation.
