DANLERS CESF PIRAR Installation guide

Brand: DANLERS

Model: CESF PIRAR

Type: Installation guide

DANLERS CESF PIRAR is a ceiling surface passive infrared occupancy switch that can be used to automatically control lighting or other electrical devices based on motion and ambient light level. It incorporates a passive infrared quad sensor to detect movement of a warm body within its detection zone and a photocell to monitor the ambient light level. Upon detecting movement, if the ambient light is dark enough, the CESF PIRAR will switch the load on. The ambient threshold can be set by the user to between approximately 100 lux and infinite lux (photocell inactive) via the LUX adjuster.

Troubleshooting

The load will not switch on:

• TheLUXadjusterissettoolowandisinhibitingtheswitch.

• TheSENSadjusterissettoolow.

• ThemovingbodyisnotemittingmoreIRthanthebackground.

  (Personwearinginsulatingclothinginawarmenvironment)

• PersonistoofarfromthePIRswitch,seedetectiondiagram.

• Personismovingunusuallyslowly(perhapswhentesting).

The load switches on when nobody is present:

• Heatercausinginfra-redvariationsinacoldsmallroomorceilingvoid
