Manual Override Mode
The light can be switched on for longer time periods by use of the Manual
Override Mode. This can be activated at night by using the internal wall switch
or circuit breaker.
• Switch the internal wall switch/circuit breaker twice (OFF/ON, OFF/ON)
within 2 seconds.
• The unit will now illuminate continuously until dawn or until it is switched
back into Auto Mode.
• To switch the unit back into Auto Mode, flick the internal wall switch/circuit
breaker (OFF/ON) once within 1 second. The unit will return to Auto Mode.
8. Troubleshooting
Problem
• The lamp stays
ON all the time
at night.
• The PIR keeps
activating for no
reason at random.
Solution
The unit may be suffering from false activation. Cover
the sensor lens completely with a thick cloth. This will
prevent the sensor from “seeing” anything. If the unit
now switches off after the set time duration and does
not re-activate, this indicates that the problem was
caused by false activation. The problem may be solved
by slightly adjusting the direction/angle of the sensor
head (See section 4. Selecting a Location).
You may not be allowing the unit time to complete its
warm-up period. Stand well out of the detection range
and wait (the warm-up period should never exceed
5 minutes). Occasionally, wind may activate the PIR.
Sometimes passages between buildings etc. can cause
a ‘wind tunnel’ effect. Ensure the unit is not positioned
so as to allow detection of cars/people using public
thoroughfares adjacent to your property.
