A curtain detector that looks both ways. Four IR sensors form two independent narrow beams, each covering 13 to 49 feet, so one device mounted on a wall protects the line in both directions along it.
Built for the installer
That geometry is what makes it useful on a facade or a boundary. Mounted centrally on a wall it protects the full length in both directions with one enrollment and one battery set, where a conventional outdoor detector would need two units angled apart. Each side can be configured independently.
The 4.5 degree horizontal beam keeps detection tight to the building line, so a pavement or a neighbouring garden outside the beam does not generate activations. SmartDetect and ELSA handle the filtering, with anti-masking, IP54 and a -13F to 140F rating.
Key features
- Two independent beams from one device, protecting a wall line in both directions
- 4.5 degree horizontal beam keeps detection tight to the building and off the pavement
- 13 to 49 ft per side, each side configurable independently
- SmartDetect and ELSA filtering with anti-masking
- IP54 and -13F to 140F for exposed facade mounting
- Pet immunity by height to 2.62 ft, weight not a factor
System requirements
Requires an Ajax hub or range extender. Designed for outdoor use. Mount on a wall so the two beams run along the protected line.
