Magnetic Wireless Door/Window Sensor Safe SAFE38100 detector, wireless magnetic contact for intrusion detection

Safe SAFE38100 is a wireless magnetic door and window detector designed to monitor opening and closing events at entry points. The sensor uses a magnetic contact to detect changes in the relative position of two parts and transmits alarm and status signals wirelessly to compatible security panels or receivers. Intended for residential and light-commercial alarm systems, this compact detector supports tamper-resistant mounting and provides basic perimeter protection for doors, windows and other movable panels.

Advantages

The Safe SAFE38100 offers simple wireless installation without running wires to each opening, reducing installation time and visual impact. Its magnetic contact mechanism delivers reliable detection of open/closed states while consuming minimal power, which helps prolong battery life. The device includes tamper monitoring to alert the system if the sensor housing is removed, and its compact form factor allows discreet placement on frames and sashes.

Suitable for

• Monitoring household doors and windows in apartments and houses
• Securing backdoors, garage doors, and service entrances
• Protecting shopfronts, display cabinets or office windows
• Use in wireless alarm systems for light-commercial premises

When it may not be suitable

This magnetic detector is designed for standard doors and windows; it may not be suitable for very large gaps, irregular mounting surfaces or heavy-duty industrial doors where more robust sensors are required. It also does not provide motion detection or glass-break sensing, so it should be combined with other detector types when broader intrusion coverage is needed.

Key specifications

• Detection type: magnetic contact (reed switch)
• Connectivity: wireless transmission to compatible security panel/receiver
• Intended installation: surface mount on door/window frame and sash
• Power: battery-powered with low consumption design
• Tamper detection: built-in anti-tamper switch for enclosure removal
• Form factor: compact two-part sensor (magnet and detector housing)

How to use

Mount the detector housing on the fixed frame and the magnet on the moving part of the door or window so that the two parts align within the manufacturer’s recommended gap. Activate the device and pair it with the compatible wireless alarm panel or receiver according to the system’s enrollment procedure. Test the sensor by opening and closing the protected point and verify that the panel receives open/close signals and tamper alerts. Replace batteries as indicated by the panel’s low-battery notification to maintain reliable operation.

What to consider before purchase

• Confirm compatibility with your alarm system’s wireless protocol and receiver
• Check the recommended mounting gap and available space on frames and sashes
• Consider environmental conditions such as outdoor exposure or heavy vibration
• Plan for battery replacement access and integration with existing sensors

Usage recommendations

For reliable perimeter security, install one sensor per opening, position components to maintain correct alignment, and include complementary detectors (motion sensors or glass-break detectors) where needed to broaden coverage. Periodically test sensors and monitor battery status through the alarm panel.
