FAQ's

Can the Knightsbridge OS0025W be installed as both surface and recessed?

Yes. The OS0025W is a 2-in-1 PIR ceiling sensor that can be installed either recessed or surface mounted. For recessed installation, it uses a 73mm cut-out and includes pre-fitted ceiling springs. For surface mounting, the springs can be removed and the supplied surface box used.

Is the OS0025W suitable for outdoor use?

No. The OS0025W is rated IP20, which means it is intended for indoor use only. It should not be installed outdoors or in areas where moisture, water spray or exposed weather conditions are present.

What is the adjustable time delay range?

The adjustable time delay range is 10 seconds to 7 minutes. This allows electricians to set how long the connected lighting remains on after motion is detected, depending on the usage pattern of the room or area.

What is the maximum switching capacity?

The OS0025W has a switching capacity of up to 2000W incandescent or 1000W LED. This makes it suitable for a wide range of indoor lighting control applications, provided the total connected load remains within the manufacturer’s stated rating.

What are the key installation dimensions?

The OS0025W has a 93mm diameter, 36mm projection, 28mm recessed depth and requires a 73mm cut-out diameter for recessed mounting. These dimensions should be checked against ceiling void depth and installation location before fitting
