Leviton ACS15-DIW 2-Zone 277V Occupancy Sensor

The Leviton ACS15-DIW is a 2-zone occupancy sensor rated for 277V electrical systems, designed to integrate into commercial and industrial lighting control circuits. As part of Leviton's ACS15 sensor series, this unit is built to detect occupancy across two independently monitored zones, allowing lighting circuits to respond to real-time space usage. The 277V rating makes it well suited for commercial building electrical systems where higher-voltage lighting circuits are common, such as office buildings, warehouses, and other facilities that rely on centralized lighting control. This sensor is intended for professional installation as part of a broader lighting control strategy, helping facility managers and electrical contractors implement occupancy-based lighting automation.

Leviton ACS15-DIW – Frequently Asked Questions

1) Can I use a 24V occupancy sensor instead of the 277V Leviton ACS15-DIW?
Not interchangeably. The ACS15-DIW is a 277V device, while low-voltage sensors like the Pass and Seymour DT300 Wattstopper dual-technology ceiling sensor and the UT3053 ultrasonic run at 24V and need a separate power pack or control module to switch line-voltage lighting. Match the sensor to how the circuit is powered before you order.
2) What does the 2-zone configuration on the Leviton ACS15-DIW actually do for me?
Two zones means the sensor monitors occupancy across two independently tracked areas, so lighting in one part of the coverage area can respond without switching the other. In practice that lets you break a single open space, such as a warehouse aisle pair or a split office, into two lighting responses off one device instead of installing two separate sensors.
3) Is the ACS15-DIW a standalone wall switch sensor or part of a larger lighting control system?
It is a system component, not a self-contained wall switch replacement. The ACS15-DIW is built to be wired into a broader commercial lighting control strategy and is intended for professional installation by an electrical contractor. If you want a single-gang device that replaces an existing toggle switch and drives the load directly, look at a wall-mount sensor such as the Pass and Seymour PW-302 Wattstopper PIR dual-relay wall occupancy sensor instead.
4) The space has partitions and cubicles that block line of sight - is the Leviton ACS15-DIW the right sensing technology?
The ACS15-DIW is specified as an occupancy sensor for commercial and industrial lighting circuits, with its published detail being the 2-zone configuration and 277V rating rather than a sensing technology. Where partitions and cubicle walls break line of sight, installers commonly move to ultrasonic or dual-technology units: the Pass & Seymour UT3053 Wattstopper is a ceiling mount ultrasonic occupancy sensor with 360 degree coverage rated to 2000 square feet on 24V, and the Pass & Seymour DT300 Wattstopper is a dual technology ceiling sensor, also 24V and 360 degrees. Both of those run on a 24V control circuit, so they assume a low-voltage control layout rather than direct connection to a 277V lighting feed.
5) What is the closest alternative to the Leviton ACS15-DIW if I need two independently switched lighting loads?
The ACS15-DIW is a 2-zone occupancy sensor, so a single unit drives two separately controlled zones. The nearest dual-load alternative is the Pass & Seymour PW-302 Wattstopper PIR dual-relay wall occupancy sensor, which uses two relays to switch two loads from one wall-mounted device. The difference in form is the deciding factor: choose the PW-302 when you want the sensor at the switch box location, and keep the ACS15-DIW where the dual-zone control is being tied into a 277V commercial lighting circuit.
6) I only need single-zone coverage in an open office - what can I use instead of the Leviton ACS15-DIW?
If the space does not need two separately controlled zones, a single-zone ceiling sensor is the simpler specification. The Pass & Seymour CI305 Wattstopper is a low-profile ceiling PIR occupancy sensor with 360 degree coverage rated to 1200 square feet, which suits one open area switched as a single load. The ACS15-DIW remains the choice when the same coverage area has to be split into two independently monitored zones.
7) Can I swap a Pass & Seymour Wattstopper DT300 in where a Leviton ACS15-DIW was specified?
Not as a direct electrical swap. The Leviton ACS15-DIW is rated for 277V systems and provides 2-zone detection, while the Pass & Seymour DT300 Wattstopper is a dual technology ceiling occupancy sensor operating at 24V over 360 degrees. The DT300 expects a low-voltage control topology with power packs or a controller handling the line-voltage lighting load, so substituting it changes the wiring design, not just the device. Confirm the control architecture on the drawing before making the change.
8) What is the exact part number and manufacturer for this 2-zone 277V Leviton sensor?
Leviton ACS15-DIW. That is the manufacturer part number to put on a purchase order or a submittal, and it covers the 277V, 2-zone configuration of the ACS15 sensor series.
9) What is the difference between the Pass & Seymour CI305 and UT3053 if I am cross-shopping against the Leviton ACS15-DIW?
Both are ceiling-mounted 360 degree sensors from the Wattstopper line. The CI305 is a low-profile PIR unit rated to 1200 square feet, while the UT3053 is ultrasonic, runs on 24V, and is rated to 2000 square feet. PIR responds to motion in its line of sight; ultrasonic covers obstructed areas. Neither is a 2-zone device - the Leviton ACS15-DIW is what provides two independently monitored zones on a 277V lighting circuit.
10) We are standardizing occupancy sensors across a warehouse on 277V circuits - which units fit and which do not?
The Leviton ACS15-DIW carries a 277V rating and is built for commercial and industrial lighting control circuits, which is the common feeder voltage in warehouse lighting, and its 2-zone configuration lets one device split a bay into two controlled areas. The Wattstopper ceiling alternatives in the same class - the DT300 dual technology and the UT3053 ultrasonic - are 24V devices, so standardizing on those means committing the facility to a low-voltage sensor network. For a facility already running 277V lighting branch circuits, the ACS15-DIW is the unit that matches the existing distribution.
11) Is a wall-mounted sensor like the Pass & Seymour PW-302 an equivalent to the Leviton ACS15-DIW?
They overlap on dual-load control but not on mounting or circuit. The PW-302 Wattstopper is a PIR dual-relay wall occupancy sensor, so it mounts in the switch box and switches two loads through its own relays. The Leviton ACS15-DIW is a 2-zone sensor rated for 277V systems and is intended for integration into a broader commercial lighting control strategy rather than as a one-for-one switch replacement. If the job is retrofitting an existing wall switch location, the PW-302 is the form factor; if the design calls for zone sensing on a 277V control scheme, specify the ACS15-DIW.
12) Is there a dual-technology alternative if PIR alone keeps dropping my lights in a quiet office?
For spaces where small motion gets missed, a dual-technology sensor combining PIR with ultrasonic holds occupancy better than PIR alone. The Pass and Seymour DT300 Wattstopper is a 24V, 360 degree dual-technology ceiling unit. The Leviton ACS15-DIW is specified for 277V dual-zone lighting control rather than by sensing technology, so pick based on whether the circuit voltage or the detection behavior is driving your decision.
