## Summary description

Cylindrical magnetic reed switch SATEL B-2T is a door/window contact sensor used in intrusion alarm systems. It provides a normally closed contact that changes state when the magnet moves away, suitable for surface or flush mounting in frames and doors. Compact cylindrical body and standard connections make it compatible with alarm control panels and auxiliary wiring in residential and commercial installations.

## Long description

Satell B-2T cylindrical magnetic reed switch is a compact door and window contact sensor designed for intrusion alarm systems. The device features a normally closed (NC) contact that opens when the magnet moves away, enabling reliable monitoring of doors, windows and other movable elements. Its cylindrical shape supports both surface and flush mounting in frames and doors, while standard connection leads ensure compatibility with most alarm control panels and auxiliary wiring in residential and commercial installations.
Advantages
The sensor offers a small, unobtrusive cylindrical housing that fits into narrow frame profiles or can be mounted on flat surfaces. Normally closed operation simplifies wiring and integration with common alarm inputs, reducing installation complexity. Mechanical construction provides consistent switching action and long-term stability in typical indoor environments. The model is suitable for both new installations and retrofit projects due to its straightforward mounting options and standard electrical interface.
Suitable for
Monitoring doors and windows in residential properties
Perimeter and entry point detection in commercial premises
Retrofit security upgrades in frames with limited installation space
Integration with alarm control panels and wired security circuits
Key specifications
Contact type: normally closed (NC) reed contact
Mounting options: surface mounting or flush (recessed) mounting
Form factor: cylindrical body for narrow frame installation
Connection: standard wired leads for direct panel connection
Intended application: indoor use for door/window alarm monitoring
How to use
Install the cylindrical reed switch on the fixed part of the door or window frame and position the matching magnet on the moving sash so that the magnet aligns with the switch when the door or window is closed. Choose surface mounting or recess the switch into a prepared hole for flush installation depending on frame material and aesthetic requirements. Connect the switch wires to the alarm control panel input configured for normally closed contacts, and verify correct operation by opening and closing the door or window to confirm the circuit opens when the magnet is removed.
Usage recommendations
For reliable operation, mount the switch and magnet with correct alignment and secure connections. Avoid exposure to direct outdoor weather without appropriate enclosure. Test the contact state after installation and during routine maintenance to ensure consistent operation within the security system.
