Pass & Seymour BZ150 Wattstopper 24 VDC Universal Voltage Power Pack, Auto/Manual On-Off Relay

The Pass & Seymour BZ150 Wattstopper Power Pack is a self-contained, 24 VDC universal voltage relay system designed to power and control low-voltage occupancy sensors within commercial lighting control systems. It offers a field-selectable auto-on or manual-on operating mode, integrates with hold-on and hold-off inputs from building management systems (BMS) and lighting control panels, and meets the materials restrictions of RoHS — making it a reliable choice for code-conscious lighting retrofit and new-construction projects.

Key Features

  • Universal Voltage Power Pack: Delivers a regulated 24 VDC output to power any 24VDC occupancy sensor from a self-contained power supply relay system.
  • Auto/Manual Operating Mode: Provides field-selectable auto-on or manual-on operation to match the required control strategy for the space.
  • BMS & Panel Integration: Hold-on and hold-off inputs integrate directly with BMS, lighting control panels, and other building systems for coordinated control.
  • Momentary Switch Compatibility: Integrates with a low-voltage momentary switch to control any connected 24VDC occupancy sensor.
  • Status Indicator LED: An onboard LED indicates the status of the relay or flags a low-voltage overcurrent condition for fast troubleshooting.
  • Efficient Switching Power Supply: Optimizes current output automatically based on the number of connected sensors for efficient operation.
  • RoHS-Compliant Materials: The product meets the materials restrictions of RoHS for environmentally responsible installations.

Pass & Seymour PAS-BZ-150 – Frequently Asked Questions

1) What does the Pass & Seymour BZ150 power pack actually do in an occupancy sensor circuit?
The BZ150 is a self-contained power supply and relay in one housing. It takes line voltage in and puts out a regulated 24 VDC to run low-voltage occupancy sensors, then switches the lighting load through its onboard relay when the sensor calls for it. That means you don't need a separate transformer plus contactor; the pack handles sensor power and load switching together.
2) Can I wire the BZ150 so the lights come on by switch instead of automatically on occupancy?
Yes. Operating mode is field-selectable between auto-on and manual-on, so you set it at install to match the control strategy for the space. In manual-on, the pack works with a low-voltage momentary switch to turn the connected 24VDC sensor circuit on, with the sensor handling the off. No different part number is needed for one mode or the other.
3) Will the BZ150 tie into our building management system for after-hours lighting override?
It will. The pack has hold-on and hold-off inputs intended for BMS, lighting control panels, and other building systems, so a scheduling or override signal from the panel can force the zone on or keep it off regardless of sensor state. That is the normal way these packs get coordinated with a central time schedule.
4) How many occupancy sensors can one BZ150 power pack supply?
The BZ150 uses a switching power supply that automatically optimizes current output based on how many sensors are connected, so it scales to the sensor count on the low-voltage side rather than being fixed to one device. Sensors must be 24 VDC types to match the pack's regulated output.
5) Will a BZ150 power pack fit above the ceiling in a standard junction box?
Body dimensions are 1.673 in height, 2.916 in width, and 1.634 in depth, which is the usual compact pack footprint mounted through a knockout on a junction box or fixture housing with the relay body sitting inside the box. Check the knockout and box free space against those numbers before you order a quantity.
6) Is there any way to tell from the pack whether the relay is energized or a sensor leg is shorted?
An onboard status LED does both jobs: it indicates relay state and flags a low-voltage overcurrent condition. On a troubleshooting call that tells you quickly whether the problem is on the sensor wiring side or downstream in the lighting circuit.
7) Is the BZ150 sold as a single model, or do I have to pick a voltage version?
One configuration only. The BZ150 is a universal voltage pack, ordered as part number BZ-150, so there is no separate 120 V and 277 V ordering decision to make across a mixed-voltage building.
8) Does the Pass & Seymour BZ150 meet RoHS for a LEED or spec-driven project?
The BZ150 meets RoHS materials restrictions, and that is the compliance item carried on the product record. It is manufactured in China. For any other listing or standard your specification calls out, work from the manufacturer spec sheet supplied with the product.
9) Can I use the BZ150 to add occupancy control to existing fixtures, or is it only for new construction?
Both. It is a self-contained pack that drops into retrofit work as readily as new construction, since it supplies its own 24 VDC sensor power and switches the load itself. The common retrofit use is adding a low-voltage sensor to an existing lighting circuit without pulling control wiring back to a panel.
