SET UP AND ADJUSTMENT
1.
Adjust the TIME setting anti clockwise to minimum (10s)
2.
Adjust the LUX setting clockwise to maximum.
3.
Switch the power on. (The control load will not work immediately, as it requires 5-30 seconds to
preheat.
4.
The sensor will activate again, 5 - 15 seconds later, once the first switching cycle is completed.
5.
If testing when the ambient light is greater than 3 LUX, the initial switch cycle will not continue to
operate. In this instance, cover the detection window with a dark object, such as a cloth. It is normal
for the cycle to stop within 5-15 seconds of completion of the initial signal.
PROBLEM
POSSIBLE SOLUTION
Lights do not turn on
Check the power is on
Check the bulbs and fixtures are working correctly
Check wiring is correct
Ensure LUX setting is set for a darker setting than present
Lights do not switch off
Make sure unit is wired correctly.
Ensure there is not a continuous signal in the detection field.
Ensure the time delay is set on the appropriate setting.
Lights do not switch on
Make sure there are no reflective sources in the detection field
Check detection window is clear
Check installation height and detection distance is in the
parameters.
TROUBLESHOOTING
WIRING DIAGRAM
As with all PIR motion sensors, the FMS - 12051 must be positioned away from any sources of heat (such as
extractor fans, dryers, any air conditioning or heating registers, etc.) Reflective surfaces and overhanging
branches may also cause false activation.
1.
Isolate the power
2.
Select a suitable location to install the unit by considering points in previous sections and the units
detection range and direction
3.
Remove the housing cover by loosening the two screws. (Fig 1)
4.
Place the back housing cover onto the surface and mark the position of the mounting holes.
5.
Drill the holes and insert wall plugs into these holes, and fix back housing cover to surface.
