Outdoor PIR Detector for Building Perimeter : BX-80N Series

 Outdoor PIR Detector for Building Perimeter : BX-80N Series

Wired Model

  • BX-80N

Battery Operated Model

  • BX-80NR

With long, narrow detection areas that extend from both its sides the BX-80N is specifically designed to be wall-mounted centrally on a building, covering the building perimeter with a multi-layered, horizontal barrier that detects intruders before they break in. To help reduce false activations, the range can be adjusted so that detection extends only to the end of the building. The unit also has a size-judging function, which helps it discriminate between large and small objects within the detection area.

The BX-80N is stylishly designed to blend in with any architecture and is simple to install and set up - there being no need to align transmitters and receivers.


  • Double conductive shielding
  • Advanced temperature compensation
  • Limited detection range function
  • Size judging function to avoid false alarms
  • Variable detection range up to 24 m (12 m on each side)
  • Audible alarm indicator to deter intruders (BX-80N only)
  • Attractive, slender design
  • Compatible with numerous wireless transmitters (BX-80N only)
  • Battery saving circuit (BX-80N only)

Size judging function

The BX-80N/80NR only triggers alarms when both upper and lower detection layers detect movements.

Advanced temperature compensation

The BX-80N/80NR uses advance temperature compensation to automatically increase the detector's sensitivity under high temperature conditions, especially where the background temperture ranges from 35 - 37 degree C, close to that of the human body.

Double conductive shielding

By using our double conductive shielding, the visible light disturbance and RFI can be blocked.
