Magnetic Contact Sensor SATEL B-1P — surface-mounted door/window reed switch

SATEL B-1P is a compact surface-mounted magnetic contact sensor designed for monitoring the open/closed status of doors and windows in alarm and access control systems. The device uses a magnetically actuated reed contact to detect changes in position and provides a reliable input for perimeter intrusion detection and basic door/window status monitoring. Its surface-mounted design makes it suitable for installations where recessed mounting is not feasible and for retrofitting existing frames.

Advantages

The magnetic contact sensor offers a simple, robust detection principle with low power consumption and long-term mechanical reliability. Its compact housing and surface-mounted format allow straightforward installation on various frame materials without the need for complex modifications. The device is compatible with standard alarm and control panels and facilitates easy integration into existing security systems.

Suitable for

• Perimeter intrusion detection on doors and windows
• Basic status monitoring of access points in residential and commercial buildings
• Retrofit installations where concealed mounting is not possible
• Integration with SATEL control panels and other compatible alarm systems

Key specifications

• Surface-mounted magnetic contact (reed switch) operation
• Compact, low-profile housing suitable for frames and sashes
• Designed for detecting opening/closing events of doors and windows
• Intended for use with alarm and access control panels
• Suitable for retrofit and new installations where recessed mounting is impractical

How to use

Mount the sensor on the fixed frame and the magnet on the moving part (door or window sash) so that the magnet aligns with the reed contact when closed. Connect the sensor leads to the appropriate input zone on the control panel following the panel manufacturer's wiring diagram and polarity recommendations. Verify correct operation by opening and closing the door or window and confirming that the control panel registers the state changes.

Usage recommendations

For reliable performance, install the contact on clean, dry surfaces and ensure correct alignment between sensor and magnet. Avoid exposure to strong mechanical shocks and corrosive environments. When integrating with alarm systems, configure the control panel for the appropriate zone type and test the sensor after installation to confirm proper detection and signal reporting.
