Finishes

White
Brightest aperture when illuminated and provides the smoothest transition to most ceilings when off (only available with a white flange).

Black
Specular finish that provides the lowest aperture brightness possible and reduces source identification in a ceiling significantly.

Dark Bronze
Specular finish that provides the lowest aperture brightness possible and reduces source identification in a ceiling significantly.

Clear diffuse
Slightly diffuse clear finish that softens the light and reduces the mirror image effect with traditional aluminum specular finishes (only available with a white flange).

Wireless Controls Options

Interact Pro scalable sensor
(System Bridge Accessory with -CS option):

• CS is a connected sensor with integral occupancy and daylight sensing and supports wireless mesh connectivity. 

• The sensor works in the Foundation mode (similar to SpaceWise) when configured without a gateway or in an Interact Pro Advanced or Enterprise mode if a compatible gateway is used. 

• Interact Pro includes an App, a portal and a broad portfolio of wireless luminaires, lamps and retrofit kits all working on the same system. 

• Startup is implemented via Interact Pro App (Android or iPhone) & BlueTooth connectivity. The App provides flexibility to choose between a gateway or non gateway mode for setup. 

• Setup with the gateway requires wired internet access to the gateway. It is possible to add a gateway at a later point.

• Prepare project configuration steps remotely and use IRT9015 remote onsite to identify and group devices together.

• Compatible with:
  – SWS200 wireless scene switch
  – Battery powered IP42 presence sensor OCC sensor IA CM WH 10/1
  – Battery powered IP42 presence & daylight sensor OCC-DL sensor IA CM IP42 WH
  – Battery powered IP65 presence sensor OCC sensor IA CM IP65 WH
  – Battery powered IP65 presence & daylight sensor OCC-DL sensor IA CM IP65 WH

• For more information on Interact Pro visit: www.interact-lighting.com/interactproscalablesystem.

Interact Pro Enterprise
(System Bridge Accessory with -SB option):

• A wireless IoT connected lighting solution for large enterprises that span across multiple floors, buildings and require multiple gateways.
