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. Check that the unit 

is not set to manual override.
Reset unit. Leave for a maximum of 5 minutes. If light activates, check area for 

false activation from heat or reflective source.
Check that the power is switched ON at the circuit breaker/ internal wall 

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. Note: sensor will not detect through glass.
The level of ambient light in the area may be too bright to allow operation at the 

current DUSK setting. At night, adjust the DUSK control slowly clockwise until 

the lamp illuminates. 
Unit may be poorly located. Check “Before you start” section for tips.

PIR sensors are influenced by weather changes and are more effective in colder 

ambient temperatures. You may need to make seasonal adjustments to the 

sensor aiming to ensure trouble-free operation all year round.
