Leviton O4C20-MDW – Frequently Asked Questions

1) Does the Leviton Provolt O3C15-IDW vacancy sensor work on a 277V commercial lighting circuit?
Yes. The Provolt 2-pole ceiling sensor is a line voltage device rated 120-277V AC, 50/60Hz, so it drops straight onto 120V, 208V, 240V or 277V lighting branch circuits without a separate low voltage power pack.
2) What ceiling height does the Leviton Provolt ceiling vacancy sensor need?
It is built for ceiling mounting between 8 and 12 feet. Below 8 feet the coverage pattern is tighter than rated, and above 12 feet detection accuracy falls off. For open offices or corridors with high decks, use a sensor rated for that height instead.
3) How much floor area will one Provolt vacancy sensor cover?
Up to 2000 sq ft per unit with the M/T sensor technology. That typically handles a conference room, break room or a section of open office from a single device. Restrooms with stalls or L-shaped rooms break line of sight, so plan on more than one head there.
4) Is a vacancy sensor the same as an occupancy sensor, and which do I need for Title 24?
Not the same. A vacancy sensor is manual-on: someone has to switch the lights on, and the sensor turns them off when the space empties. An occupancy sensor turns lights on automatically. Manual-on vacancy control is what many energy codes call for in offices and similar spaces, and this Provolt unit is stated CEC and Title 20/24 compliant.
5) What do the IDW and MDW configuration codes on the Leviton Provolt sensor mean when I order?
Two configurations are offered: O3C15-IDW and O4C20-MDW. Specify the code on your purchase order, because they are different sensor models, not just packaging. Confirm which one matches the head called out on your lighting control schedule before releasing the order.
6) Will this sensor keep the lights off when there is enough daylight in the room?
Yes. Ambient Light Override is built in, so the sensor holds the lighting off when daylight already meets the level in the space. That is what makes it usable in perimeter offices and rooms with glazing where you do not want the fixtures energized on a bright afternoon.
7) Do I have to set sensitivity or time delay on the Provolt sensor during commissioning?
Auto-calibration handles sensitivity on its own, which cuts the commissioning step most ceiling sensors need and keeps detection steady as the room's use changes. For a contractor doing a floor of identical offices, that means mount, wire and move on rather than tuning each head.
8) What does 2-pole mean on this line voltage sensor, and why would I need it?
Two-pole switching lets the sensor control two separate switched loads or legs from one head, which is how you handle dual-level or split-circuit lighting in a room off a single sensor. If you only have one switched load, a single-pole sensor will do the job.
9) What color is the Leviton Provolt ceiling sensor, and will it blend with a white acoustical ceiling?
White finish, which matches standard white ceiling tile and most lay-in grid. There is no other color offered on this 2-pole line voltage model.
