Ceiling Occupancy Detector 12/24 Volt AC/DC VFC

The EBDSPIR series of presence detector switches is designed to provide automatic control of lighting, heating or ventilation loads. They detect movement with a PIR sensor and turn on the load. When an area is no longer occupied, the load will switch off after an adjustable time-out period. An optional adjustable internal light sensor provides additional energy saving in lighting applications. When an area is occupied, lighting is switched on only when the level of natural light falls below a preset threshold. The EBDSPIR-24V-NLVFC product does not have the internal light sensor. When the unit is first powered up, the PIR sensor will always detect immediately, regardless of whether the room is occupied. This unit has a 12-24VAC/DC low-voltage power supply and provides an isolated voltage-free contact output.

Installation

● The detector should be sited so that the occupants of the room fall inside the detection pattern shown overleaf, at a recommended height of 2.8m on the ceiling. Note that the lower the sensor is installed the smaller the detection range will be, subject to the parameters shown on the diagram.
● Avoid direct sunlight entering the sensor.
● Do not site within 1m of forced air heating or ventilation.
● Do not site within 1m of any lighting.
● Do not fix to a vibrating surface.
● Wire the product using the connector using the diagram on the front page.
● Mount using one of the two options above.
● To switch from more than one position, simply wire two or more units in parallel.
● For lux-enabled products, set the LUV level to maximum and the time to minimum.
● Power the unit up – the load should come on immediately.
● Vacate the room or remain very still and wait for the load to switch off (should take no more than 2 minutes).
● Check that the load switches on when movement is detected.
● To set the final LUX level, wait until the level of natural daylight is just enough that lighting is required. Starting with the LUX control turned fully clockwise (at minimum), very slowly turn the control anti-clockwise until the lights come on. Note that when the LUX control is at maximum, the lights will always come on with occupancy.
● Set the time required.
