10. Troubleshooting
Problem
• The Lamp stays ON
all the time at night.
Solution
Cover the PIR lens with a thick cloth.
If the light turns OFF, check the detection
area for heat or a reflective source. If the light
stays ON, check the wiring (See section 5.
Installation and Connection).
• The PIR keeps
activating for no
reason at random.
Turn OFF at the isolation switch. Turn back ON
again after 30 seconds. Leave for approximately
15 minutes. If the light activates, check for false
activation from heat, wind or a reflective source.
• PIR sensor will not
operate at all.
Check that the power is switched ON at the
isolation switch. Turn OFF the power to the unit
and check the wiring connections. Check the
lamp (if it’s changeable). If the lamp has failed,
replace. Ensure the lamp is seated correctly in
the lamp-holder. Note: the unit will not detect
through glass (e.g. in a glazed porch).
• PIR sensor will not
operate at night.
The level of ambient light in the area may be too
bright to allow operation at the current DUSK
setting. During the hours of darkness, adjust the
DUSK control slowly clockwise until the lamp
illuminates.
• PIR activates during
the daytime.
Adjust the DUSK control setting anticlockwise
to lower the level of ambient light required
for activation.
