## Summary description

SATEL B-2 is a cylindrical magnetic reed contact designed for surface mounting in security and alarm systems. The device provides door/window open/close detection via a magnetically actuated switch in a compact cylindrical housing. It is intended for reliable zone monitoring in residential and commercial intrusion detection applications where a discrete surface-mounted contact is required.

## Long description

SATEL B-2 is a cylindrical magnetic reed sensor designed for surface mounting to detect opening and closing of doors and windows in alarm and security systems. The compact cylindrical housing contains a magnetically actuated switch that changes state when the magnet and contact are separated or brought together, enabling reliable zone monitoring in residential and commercial intrusion detection installations where a discreet surface-mounted contact is required.
Advantages
The SATEL B-2 offers a compact, low-profile design that is easy to install on most door and window frames without recessing. Its magnetic reed mechanism provides a simple, passive switching solution that does not require power for operation, reducing installation complexity and ongoing maintenance. The cylindrical housing is robust enough for typical indoor use and allows flexible placement on flat or slightly curved surfaces.
Suitable for
 Detection of door and window open/close events in residential alarm systems
 Perimeter monitoring of offices, shops and small commercial premises
 Retrofit installations where surface-mounted, non-recessed contacts are preferred
 Zones requiring discrete, low-profile contacts for aesthetic reasons
Key specifications
 Form factor: cylindrical surface-mounted contact
 Detection principle: magnetically actuated reed switch
 Installation type: surface mounting on doors, windows or frames
 Typical use environment: indoor residential and commercial applications
 Construction: compact housing suitable for flush or offset placement on frames
How to use
Mount the cylindrical contact and matching magnet on the door (or window) and frame so that the magnet aligns with the reed switch when the door or window is closed. Secure the sensor body to the surface using screws or adhesive as appropriate for the mounting surface and follow the security system manufacturer’s wiring diagram to connect the reed switch to the control panel or zone input. Test the contact by opening and closing the door or window to verify correct state changes on the alarm system before finalizing the installation.
Usage recommendations
Place the sensor and magnet on clean, dry surfaces and avoid large gaps or misalignment that could prevent reliable switching. For exterior-exposed doors or windows use compatible environmental protection or install the device in a sheltered location. Periodically check the mounting and wiring during routine system maintenance to ensure continued reliable operation.
