Wired PIR Motion Sensor Passive Infrared Detector for Home Security Systems 120 Degree 6-10m White

This wired passive infrared (PIR) motion sensor offers a reliable and straightforward solution for detecting movement in residential, educational, and commercial settings. Operating on a standard 9-16VDC supply, the detector uses a normally closed (NC) alarm relay to trigger your existing security system when infrared changes are sensed. Its 120-degree detection angle and 6-10 metre range cover a wide area, making it suitable for corridors, rooms, and entry points. The wall-mounted design allows fixed positioning, and the wired communication mode provides a stable connection free from wireless interference. At just 100 grams and in a clean white finish, it integrates neatly into most interiors.

Features and Construction

The detector is built around a passive infrared sensor that responds to heat changes from moving people or animals. Its specifications are tailored for reliable indoor use in temperatures from -10 to 60 degrees Celsius.

Detection Performance

The sensor offers a 120-degree horizontal detection angle and a range of 6 to 10 metres, giving broad coverage for typical room sizes. The quiescent current is very low at 15 microamps, keeping power consumption minimal when idle, while the alarm current of 17 milliamps ensures sufficient signal strength during activation.

Wired Communication

Wired connection eliminates the signal dropouts and battery changes associated with wireless alternatives. The NC alarm output works with most standard alarm panels and relays, providing a simple integration path for existing wired security systems.

Wall Mounted Design

Designed for permanent wall mounting, the detector can be positioned at the recommended height for optimal coverage. Its compact white housing blends with walls and ceilings, reducing visual impact while maintaining functionality.

Uses and Placement

This infrared detector is suited for a range of indoor applications where reliable motion sensing is needed. Its wired nature makes it especially reliable for fixed installations.

Home Security

Place in hallways, living rooms, or near entry doors to detect unexpected movement when the system is armed. The 120-degree angle covers a wide approach path, and the 6-10 metre range works well for most domestic corridors and open-plan areas.

Commercial Premises

Suitable for shops, schools, and banks, where coverage of larger spaces or multiple zones is required. Multiple detectors can be daisy-chained using the NC relay output to cover separate rooms or floors without complex wiring.

Entryways and Corridors

Ideal for monitoring long hallways or stairwells where a single detector can cover the entire area. Wall mounting allows easy alignment to focus on the most likely paths of movement.

Benefits and Buying Value

This detector offers a practical balance of performance, simplicity, and cost-effectiveness for wired security systems.

Reliable Wired Connection

No batteries to replace, no wireless signal fading. Once connected, the detector works consistently as long as the 9-16VDC supply is maintained. This makes it a low-maintenance component of a permanent security setup.

Broad Coverage Angle

With a 120-degree detection angle and 6-10 metre range, a single unit can monitor a substantial area, reducing the number of detectors needed per room. This saves on installation effort and component cost.

Simple Integration

The NC alarm output is compatible with most standard alarm panels and relays, making it easy to add to an existing system or use as part of a new build. The included instruction manual provides clear connection guidance.
