Solution
Cover PIR lens with a thick cloth. If the
light turns out, check detection area for
heat or reflective source.
If the light stays on, check wiring.
See Section 3.
Turn off at the isolation switch. Turn
back on again after 30 seconds. Leave
for approximately 18 minutes.
If light activates, check area for false
activation from heat, wind or reflective
source.
Check that the power is switched ON
at the power supply or isolation switch.
Turn OFF the power to the unit and
check the wiring connections.
Check the lamp. If the lamp has failed,
replace. Ensure that the lamp is seated
correctly in the lampholder. Please note
that the unit will not detect through
glass. (e.g. in a glazed porch).
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. Refer to previous section
for more details.
Adjust the DUSK Control setting anti-
clockwise to lower the level of ambient
light required for activation.
