## Summary description

SATEL B-1S is a surface-mount magnetic reed switch designed for door and window contact sensing in alarm and security systems. The device is a normally closed (NC) contact that opens when the magnet is moved away, enabling zone monitoring and tamper detection.

## Long description

SATEL B-1S is a surface-mount magnetic reed switch for door and window contact sensing in alarm and security systems. The device operates as a normally closed (NC) contact that opens when the magnet is moved away, allowing reliable zone monitoring and simple integration with most control panels. Its compact surface-mount design makes it suitable for installations where recessed mounting is not possible, and the construction supports both residential and commercial intrusion detection applications.
Advantages
The surface-mount form factor permits quick installation on door and window frames without the need for mortising. Being a normally closed magnetic reed switch, it provides straightforward wiring and clear state detection for alarm systems. The contact operates with minimal mechanical wear, ensuring long operational life and consistent switching behavior. Its compact dimensions and unobtrusive appearance reduce visual impact while maintaining reliable magnetic sensing.
Suitable for
Monitoring doors and windows in homes and apartments
Perimeter and entry point detection in commercial premises
Integration with wired alarm control panels and zone inputs
Retrofit installations where surface mounting is preferred or required
Key specifications
Operating mode: normally closed (NC) magnetic reed contact
Mounting type: surface-mount for doors and windows
Contact actuated by magnet proximity; opens when magnet is moved away
Compact physical size suitable for visible or concealed placement on frames
Designed for wired connection to standard security system zone inputs
How to use
Position the reed switch and the matching magnet on the door or window and its frame so that the magnet keeps the contact closed when the door or window is in the normal (closed) position. Secure both parts with screws or adhesive following the alignment marks, ensuring the magnet gap does not exceed the recommended operating distance for reliable switching. Connect the reed switch wires to the alarm control panel zone input according to the panel wiring diagram, observing correct polarity if required. Test the contact by moving the door or window to confirm the circuit opens when the magnet is separated and that the control panel registers the change.
Usage recommendations
For reliable performance, install the switch away from strong external magnetic fields and metal obstructions that could affect sensitivity. Verify alignment and gap during and after installation, and perform periodic functional tests as part of routine security system maintenance.
