It is a normally closed contact that opens when the magnet is moved away, suitable for mounting on doors or windows to monitor open/close status.

## Long description

SATEL B-1F is a surface-mount magnetic reed switch designed for monitoring doors and windows in intrusion detection systems. This normally closed contact opens when the magnet is moved away, providing a reliable signal to alarm panels that accept passive magnetic contacts. The compact plastic housing is intended for external mounting on frames and leaves, enabling discreet installation in residential and commercial environments.
Advantages
The SATEL B-1F contact offers a simple, maintenance-free design with passive operation that does not require a power supply, ensuring compatibility with a wide range of alarm control panels. Its normally closed configuration helps detect circuit interruptions caused by opening doors or windows, while the surface-mount form factor allows installation without recessed drilling. The device’s low-profile housing supports straightforward placement on most door and window frames.
Suitable for
 Monitoring inward- or outward-opening doors in homes, offices, and shops
 Protecting windows and sliding doors against unauthorized opening
 Integration with wired alarm panels and security systems requiring passive magnetic inputs
 Retrofit installations where surface mounting is preferred over recessed sensors
Key specifications
 Type: surface-mount magnetic reed switch
 Contact function: normally closed (NC)
 Activation principle: magnet proximity — opens when magnet is moved away
 Mounting: surface installation on door/window frames
 Housing: low-profile plastic enclosure suitable for visible mounting
 Environment: indoor use in residential and commercial settings
How to use
Mount the SATEL B-1F contact on the fixed frame and the accompanying magnet on the moving leaf so that the magnet aligns with the contact when the door or window is closed. Connect the contact leads to the alarm panel input designed for passive magnetic contacts, observing the panel manufacturer’s wiring instructions. Test the sensor after installation by opening and closing the protected aperture to confirm the panel registers the change of state. Secure the housing with appropriate screws or adhesive as suited to the mounting surface.
Usage recommendations
Position the magnet within the manufacturer-recommended gap to ensure reliable operation; avoid placing the contact near heavy electrical equipment or sources of strong magnetic fields. For exterior-facing doors and windows, choose protected mounting locations to minimize exposure to weather and physical damage. Periodically inspect the housing and wiring for mechanical wear or corrosion and verify correct operation during routine security system checks.
