## Summary description

Satel B-3 is a side-mounted magnetic contact (kontaktron) designed for intrusion detection on doors and windows. Manufactured by SATEL, it provides a compact reed-switch sensor for alarm and security systems, suitable for mounting on frames where a low-profile side installation is required.

## Long description

SATEL B-3 is a side-mounted magnetic contact designed for intrusion detection on doors and windows. The compact reed-switch sensor is intended for mounting on the edge of frames where a low-profile side installation is required. It is compatible with standard alarm and security control panels and provides a discreet solution for perimeter protection in residential and commercial premises.
Advantages
The SATEL B-3 side-mounted contact offers a simple mechanical design with reliable magnetic switching, enabling stable detection of door and window openings. Its small dimensions and side-mount form factor allow installation in narrow frame profiles or recessed positions without altering the visual appearance of the openings. The device requires no power supply for the sensor itself, reducing complexity and potential points of failure in an alarm circuit.
Suitable for
 Standard wooden, PVC and aluminium door and window frames with limited mounting depth
 Perimeter protection in apartments, houses and small commercial premises
 Retrofit installations where surface-mounted contacts are undesirable
Key specifications
 Type: Side-mounted magnetic contact with reed switch
 Mounting: Side/edge installation in frame profiles
 Installation profile: Suitable for narrow or recessed frame sections
 Electrical interface: Passive contact (reed switch) compatible with alarm inputs
 Dimensions: Compact, low-profile housing for discreet placement
 Operating principle: Magnetic proximity detection between contact and magnet
How to use
Fit the SATEL B-3 contact to the side of the door or window frame so that the magnet mounted on the moving sash aligns with the reed switch when the opening is closed. Connect the contact leads to the alarm control panel input according to the panel manufacturer’s wiring diagram, observing correct polarity if specified and using normally closed or normally open configuration as required by the system. Test the contact operation by opening and closing the door or window and verifying that the control panel registers state changes reliably.
Usage recommendations
Place the contact in a position where the magnet and reed switch have consistent alignment when closed; avoid locations with significant metal obstructions that may affect magnetic field or mechanical operation. For long cable runs, use appropriately rated alarm cable and secure wiring to prevent mechanical strain. Perform periodic functional tests as part of routine system maintenance to ensure reliable perimeter detection.
