Installation
1. Connect the DALI connector to the socket located at the rear of the sensor.
2. Flush fixing: Insert the unit into the ceiling or wall (see Connection and Fixing: Flush Fixing); or
Surface mounting: Install the unit using the SBB-A surface back box (see Connection and Fixing: Surface Mounting).
3. Power the unit up.
4. Configure the unit using Designer or Toolbox.
5. If the load triggered by the sensor comes on, by default it will take 20 minutes (of no movement detected) for the
load to switch off.
Installation Notes
• Position the sensor so that the occupants of the room are normally inside the detection zone.
• Do not fix the sensor to an unstable or vibrating surface.
• Do not install the sensor within one metre of any lighting, forced air heating, or ventilation equipment.
• Consider the possible effects on infrared detector of layers of hot and cold air in large buildings.
Layers of cold or hot air can form in the upper part of large buildings, such as warehouses, due to a number of factors,
including the layout of the building, heating and ventilation systems, shelving system arrangements, roofing materials and
the weather. If the sensor is positioned in or above such a layer of air, the sensitivity of the sensor cannot be guaranteed.
