The AA48 auxiliary relay is a low-voltage relay device that expands the switching capacity of an AA47 power pack, controlling additional circuits in response to a signal from an MSC occupancy sensor. The relay has an SPST, normally open output that is controlled directly by the MSC. The relay is rated for maximum 15 A tungsten and 20 A ballast loads. Mount the AA48 either inside or outside a standard junction box using a 1/2 in, threaded EMT nipple. Route power to the sensor using plenum-rated cable.
