WattStopper BZ-50RC – Frequently Asked Questions

1) Can this power pack be installed above a drop ceiling in a return air plenum?
Yes. The BZ-50RC carries a UL 2043 plenum rating, which is the listing inspectors look for when a control device sits in an air handling space above a suspended ceiling. That covers the typical occupancy sensor install where the pack mounts to a junction box knockout in the plenum rather than inside the room.
2) What does a low voltage power pack like the WattStopper BZ-50RC actually do in an occupancy sensor system?
It's the switching leg between the low voltage control and the line voltage load. Occupancy sensors, wall switches, and similar controls run on low voltage; the BZ-50RC takes that low voltage signal and switches the 120, 230, or 277 VAC lighting circuit. It also supplies the low voltage power the sensors run on, and it has overcurrent protection on that low voltage side so a pinched or shorted sensor lead doesn't take out the controls.
3) How do the sensors connect to the BZ-50RC - screw terminals or plug-in?
RJ45. The BZ-50RC uses an RJ45 connection for the low voltage side, so sensors and control devices with matching patch leads plug straight in rather than being landed on screw terminals. Plan your low voltage runs around RJ45 cabling and factor that into what you order with the pack, because a device with bare low voltage conductors will need an adapter or a different pack.
4) Can I override the lights on or off from a building system with this power pack?
The BZ-50RC has both Hold ON and Hold OFF inputs. Hold ON forces the load to stay energized regardless of sensor state, which is what you use for cleaning crews, events, or a life-safety override. Hold OFF keeps it de-energized, typically driven off a time clock or a BAS after-hours signal. Those two inputs are what let the pack sit inside a larger scheduling or energy management scheme instead of running purely off local occupancy.
5) Is zero crossing switching worth it on a lighting relay, or is it marketing?
It matters on the load side. The BZ-50RC switches at the zero crossing point of the AC waveform, so the relay contacts make and break when instantaneous voltage is near zero. That cuts the inrush arcing that pits contacts, which is the usual failure mode on relays feeding ballast and driver loads that cycle many times a day. On a corridor or restroom pack that switches dozens of times daily, it's the difference between a relay that lasts and one you go back for.
