The detector head comes with a pre-wired 300mm lead which plugs into the separate power supply unit.
The direct dim and analogue dim variants of the detector have a dimming output that 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). The output level can be overridden using the switch input (see
below) or the user handset.
All products support presence and absence detection. 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. 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.
Switch operation:
EBMPIR-B or -PRM single switch: short press turn on, long press turn off.
EBMPIR-DD & EBMPIR-AD single switch: short press turn on, short press turn off, press and hold cycles
dimming.
EBMPIR-DD & EBMPIR-AD two way switch: up button short press turns on, press and hold to dims up.
Down button short press turns off, press and hold dims down.
