OVERVIEW
The MP20 power/relay pack and MSP20 secondary relay pack work with low voltage occupancy
sensors to switch lighting loads on and off. The MP20 also transforms 120, 240, and 277 VAC
single phase power to Class 2 15 VDC to power remote sensors. Although plenum rated, the
elongated mounting nipple allows for these packs to be mounted either directly through a 1/2
inch knockout in a junction box, or to be located inside an adjacent box for specific local code
requirements. Up to 14 sensors may be connected to one MP20. Multi-circuit control can be
handled by multiple MP20 or MSP20 packs. MP20s can be wired continuously hot (line side),
or on the switch leg (load side) without nuisance delays upon turn on.
