WATT STOPPER

What the brand is known for

Wattstopper (a Legrand brand) is recognized across commercial and institutional markets for robust lighting control hardware: occupancy and vacancy sensors, power packs and switchpacks, time switches and both distributed and networked lighting control systems (Digital Lighting Management or DLM). The brand is widely specified for energy-code compliance projects, retrofit sensor upgrades and integrated lighting-control systems used in offices, schools, healthcare, corridors and other common areas.

Primary product families and technologies

• Occupancy and vacancy sensors: passive infrared (PIR), ultrasonic, and dual-technology (PIR + ultrasonic or PIR + microwave) sensors in ceiling and wall form factors; low-profile, high-density and extended-range patterns.
• Power packs and load control: low-voltage power packs (BZ series) that supply groups of sensors and provide integration inputs for building systems.
• Time switches and wallbox controls: digital timers and manual-on/auto-on low-voltage wall switches and keypads.
• Networked lighting controls: Wattstopper DLM (wired and wireless) and Wattstopper PLUS solutions for scalable, addressable control and system commissioning.
• Panels and relay modules: contractor panels, relay packs and interface modules for centralized control and load shedding.

Common applications

Typical uses include new construction and retrofit projects where energy codes require automatic lighting control, classrooms and offices, restrooms and corridors, and integrated campus systems needing scheduling, zoning and analytics. Contractors and facility teams also rely on Wattstopper for fixture-integrated or ceiling-mounted detection where precise coverage patterns are needed.

Procurement and model-identification guidance

• Confirm voltage and control type: low-voltage (24 VDC) vs line-voltage (120/277/347 VAC).
• Read part suffixes for finish and options (common colors: white, ivory, gray).
• Match mounting and coverage: center 360° vs corner or linear patterns.
• Verify relay/load ratings and LED compatibility and consult datasheets for wiring diagrams and environmental limits.

Replacement and sourcing tips

Always cross-check the installed part number and application, identify any BZ-series power pack for low-voltage sensors, confirm LED and driver compatibility, and verify mechanical fit for ceiling or wall installations. Do not assume availability — request lead times and pack quantities when placing orders.

How Safsale helps buyers

• Listings with clear product titles, photos and option details to match mounted devices.
• Manufacturer PDFs and cut sheets for electrical, wiring and coverage verification.
• Reviews and Q&A that provide installer feedback and common substitution notes.
• Side-by-side comparison of Wattstopper models to simplify specification and procurement.

Practical procurement checklist

Capture the full manufacturer part number; confirm voltage and power-pack needs; verify relay ratings and LED/driver compatibility; confirm mechanical fit; attach datasheets to POs and submittals.

Why Wattstopper is frequently specified — field-proven sensing technologies, broad model coverage and scalable DLM/PLUS architectures make it a common choice where energy savings, reliability and integration are priorities. For procurement teams the essential step is always to validate the exact part number and electrical requirements against the installed system before ordering.
