The EBDSPIR-AD PIR (passive infrared) presence detector provides automatic control of lighting loads
with optional manual control. It can be used on fluorescent and compact fluorescent lighting with 1-10V
analogue dimming ballasts. The unit detects movement using a PIR sensor and turns the load on. When
an area is no longer occupied the load will switch off after an adjustable time out period.
The detector can be used to control the light output of luminaires that are fitted with dimming ballasts. The
detector measures the overall light level in the detection area and calculates the correct output for the
luminaires, to achieve a preset lux level (maintained illuminance).
Two input terminals can be used to manually override the dimming levels and override the lights on or off.
An integral infra-red sensor in the unit allows the unit to be programmed using the optional DD-LCDHS
programming handset. This gives complete flexibility over many of the operating parameters. Without the
handset, manual adjustments can be made to the sensitivity, lux and time settings using the controls on
the rear of the sensor head.
The UHS user handset can be used to change output lux levels and override the lights on or off.
Two standard units are available:
EBDSPIR-AD - presence detection:
When movement is detected the load will automatically turn on. When the area is no longer occupied the
load will automatically switch off after an adjustable time period.
EBDSPIR-AD/ABS - absence detection:
The load is manually switched on. When the area is no longer occupied the load will automatically switch
off after the adjustable time period has elapsed. Note that the EBDSPIR-AD can be programmed to
absence detection using the programming handset.
In most applications the EBDSPIR-AD can be used with simple manual adjustment. However, the
EBDSPIR-AD unit has a comprehensive set of features that can be set using the DD-LCDHS handset.
Alternatively the units can be commissioned as follows:
On-site commissioning service - please contact our sales department for details.
Pre-commissioning service - the units will be despatched to site with the correct features set. The
