Motion sensor
Uses and features
Choose adjustable carrier radar, recessed infrared or surface-mounted infrared sensing. The 30°, 90° and 110° series have different model numbers; select for approach direction, obstructions and the mounting surface. Laser-model mapping and top/bottom connector labels still need confirmation. Photographs alone do not establish compatibility.
Match the environment
Assess the sensing method for doorways, corners and open spaces.
Controller interface
Verify sensor power, connector and protocol compatibility together.
Components and details
Recessed infrared sensor
A round recessed design. Check the cut-out, detection angle and range for the selected model before installation.
Carrier radar sensor
For stair sensing. Check controller compatibility, connectors and upper or lower stair placement before installation.
Specifications & selection

Installation planning
Before installation
Record the site conditions, then use the selected model’s instructions to plan installation and wiring.
Mark normal approach positions and directions and nearby objects that may affect sensing.
Check mounting requirements for the model. The 30°/90° recessed infrared sources list a 20 mm cutout; verify the actual unit before drilling and confirm direction connectors before wiring.
Test upward and downward travel, pauses and nearby passing traffic.
Fix in place after testing, leaving access for orientation changes and servicing.
