Description
Base coverage for the kit runs to B501AP, B501 and B401. Collar choice follows the base: the short collars with the two short tabs align with the screw holes on the B501AP base, while the high collars with the four longer tabs align with the screw holes on the B501 and B401 bases.
On site the kit is mounted in a suspended ceiling or in drywall, and it may be used with standard junction boxes connected to flexible conduit. The sensor base is inserted into the kit, and the sensor plugs in once the base wiring is done.
RMK400AP is the System Sensor recessed mounting kit that sets a sensor base into suspended and drywall ceilings where the application demands a lower profile sensor. It is the kit for white sensors, the RMK400AP-IV being the one for Ivory coloured sensors. Fitted this way, any System Sensor sensor mounted in a standard 102mm diameter base loses up to 20mm of depth.
The material is PC/ABS Pure white and runs to an interior diameter of 103 mm against an exterior diameter of 143.5 mm, with an overall height of 31 mm and a weight of 0.1Kg. The ceiling cut-out worked for it is 107 mm. A special mounting bracket is built in, securing the kit and base assembly to the junction box and ceiling panel, and standard junction boxes connected to flexible conduit may be used with it.

Drywall and suspended acoustical panel ceilings are the appropriate settings for the kit. Fitting turns on choosing the correct screw collars to match the type of base being used, after which the sensor base is inserted into the RMK400AP.
