![]() |
|
Ceiling flush-mounted PIR absence switch / dim control. When someone enters a room the lights are turned on using a wall switch. When the occupant leaves the room or area of detection the CEFLA PIRSD automatically switches the lights off after a pre-selected time. Product code: CEFLA PIRSD |
Switch / dim function
Pressing a momentary wall switch again (while the CEFLA PIRSD is in its ON state) will operate the SWITCHING AND DIMMING functionality of the ballast (third party).
Please refer to ballast manufacturers data sheets for operation and synchronisation of the ballast.
Ideal for meeting rooms, bedrooms, hotel rooms, student and military accommodation, classrooms etc. These neat and unobtrusive models are ideal for flush mounting through suspended or plasterboard ceilings. They have a 2m cable, for quick installation.

Strong detection zone
ie. person moving armSecondary detection zone
ie. person walking (less sensitive when walking straight towards PIR switch)PIR Quad detector gives 124 detection areas within the zone

For optimum coverage recommended mounting height between 2.4 and 5m
Several CEFLA PIRSD switches
In open plan areas
For best coverage the CEFLA PIRSD should be spaced every 5m in either direction
