## Long description

The SATEL B-2FLF magnetic door contact is a cylindrical surface-mount reed switch designed for intrusion detection and alarm systems. Housed in a compact cylindrical body, this normally closed magnetic contact is intended for installation on door or window frames where a low-profile, surface-mounted sensor is required. It provides a simple, reliable method to detect opening and closing events and to interface with alarm control panels.
Advantages
The cylindrical reed switch design offers a discreet and space-efficient sensor suitable for narrow frames and sashes. As a surface-mount device, it eliminates the need for mortising and allows quick installation on a variety of door and window types. The normally closed contact provides a straightforward wiring setup and predictable behavior for most alarm systems. Its robust mechanical housing provides stable operation in everyday conditions typical for residential and light commercial installations.
Suitable for
 Monitoring opening/closing of single- and double-leaf doors
 Window contact sensing on framed windows and sashes
 Integration with wired alarm control panels and zones
 Surface-mounted installations where recessed mounting is not possible
Key specifications
 Type: cylindrical reed switch, surface-mount
 Contact configuration: normally closed (NC)
 Mounting: surface installation on frame or sash
 Application: door and window opening/closing detection
 Compatibility: designed for use with standard wired alarm systems and control panels
 Physical form factor: compact, low-profile cylindrical housing
How to use
Place the magnetic contact on the fixed frame and the magnet or mating part on the moving sash or leaf so that the contacts align when the door or window is closed. Fasten the sensor using appropriate screws or adhesive as required by the mounting surface and ensure the wiring is routed to the alarm panel zone input. Connect the normally closed contacts to the designated zone terminals of the control panel following the panel manufacturer’s wiring diagram and observe polarity and tamper wiring requirements where applicable. After installation, test the contact by opening and closing the door or window to confirm correct signaling to the alarm system.
Usage recommendations
Install the sensor on clean, dry surfaces and avoid locations where mechanical stress or heavy vibration may cause false signals. Maintain correct alignment between the contact and its counterpart to ensure reliable operation. For outdoor or high-moisture environments, choose an appropriate protective mounting method or housing and consult system documentation to verify environmental suitability.
