Operation – Microwave Sensor (where fitted)
Detection Range:
This determines the effective range of the motion detector and is set by DIP switches on the sensor itself, refer to figure. Note that
reducing the sensitivity will narrow the detection range. The following settings are available:
i. Maximum up to 5m
ii. Range up to 3.5m
iii. Range up to 2m
iv. Range up to 1.5m
v. Range up to 1m
Hold Time:
This determines the time the fitting remains at 100% level after motion is last detected and is set with DIP switches at the sensor itself,
refer to figure. The walk test setting is useful when installing the fitting to establish correct operation and range. The following settings
are available:
i. walk test mode
ii. 30s
iii. 3 minutes
iv. 5 minutes
v. 15 minutes
vi. 25 minutes
Daylight Sensor:
This setting holds off the 100% light output should there be sufficient daylight and is set using DIP switches at the sensor, refer to
figure. The following settings are available:
i. 2 lux darkness only
ii. 5 lux darkness only
iii. 20 lux twilight
iv. 30 lux twilight
v. *daylight, photocell disabled.
*In daylight setting the lamps will always be on with motion detection and operate at 100% light output, even in bright
