Detection diagram
Detection Mode
The Detection Mode can be set to behave in Presence or Absence mode:
 Presence 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 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.
In either case, sensitivity to movement of the Microwave sensor can be adjusted using the Sensitivity parameter.
HINT: To assist in setting the Sensitivity, turn on the Walk Test LED which will flash red when movement is detected.
Switch Level On/Off
 Occupancy detection can be made dependant on the ambient light level using the Lux On Level and Lux Off Level
parameters.
 The level can be set independently for each channel (UNLCDHS only). For example Channel 1 turns on with
occupancy whereas Channel 2 is held off by Lux.
Normally closed option
The MWS6-PRM-2CH-NC provides a normally closed contact for fail safe operation. If the unit fails, the outputs will
default to on.

Note. If the range is compromised by the ceiling construction /
material. Add the supplied 20mm spacer ring. See page 4 for
fitting details.
