Lutron Maestro Dual-Tech Vacancy Sensor Switch 6 A, Black Bulk Pack (WMS-A102-V-BTBU)

Product Overview

The Lutron WMS-A102-V-BTBU is a Maestro series dual‑technology vacancy sensor switch that replaces a standard wall switch to provide automatic lighting shutoff. It combines PIR and ultrasonic sensing and is rated for 6 A switching at 120–277 V for single‑pole circuits.

This SKU is supplied in a Black Bulk Pack format intended for contractor and commercial installations that require code‑compliant automatic lighting control and vacancy operation (manual-on, automatic-off).

Key Features

• Dual‑tech sensing (PIR + ultrasonic) to reduce false triggers
• Vacancy mode: manual on, automatic off when room is vacant
• 6 A switching capacity at 120–277 V for single‑pole applications
• Adjustable time‑out and sensitivity to tune detection to room usage
• Designed to replace a standard wall switch for retrofit installations

How this sensor works

The WMS-A102-V-BTBU uses dual‑technology sensing—passive infrared (PIR) combined with ultrasonic detection—to recognize human presence and reduce false activations that can occur with single‑technology sensors.

It is configured for vacancy mode, which requires the occupant to turn lights on manually; the sensor will automatically turn lights off when it detects the room is empty based on its sensing algorithms and time‑out setting.

• Vacancy mode: manual on, automatic off
• Dual‑tech (PIR + ultrasonic) sensing reduces missed or false triggers

Electrical rating and configuration

Use the WMS-A102-V-BTBU on single‑pole circuits within its electrical ratings to ensure proper operation and safety.

• Switching capacity: 6 A
• Voltage range: 120–277 V
• Configuration: single‑pole

Typical applications

This Maestro vacancy sensor is intended for locations where automatic shutoff is desired but manual on is preferred or required by occupant workflow or code. It is commonly used in commercial and institutional settings.

• Energy‑code automatic lighting control
• Offices, restrooms, classrooms, storage rooms
• Retrofit replacement for a standard wall switch

Installation and setup considerations

Install the WMS-A102-V-BTBU in place of a standard single‑pole wall switch following local electrical code. After installation, set the device’s vacancy/occupancy mode and adjust the time‑out and sensitivity to match room traffic and layout.

• Set vacancy/occupancy mode and time‑out before commissioning
• Adjust sensitivity and time‑out to minimize nuisance off/on events
• Intended to be mounted in a standard wall box as a direct replacement for a manual switch

Before You Order

Confirm the model number and quantity required before ordering. Verify that the circuit is single‑pole and that the load does not exceed 6 A at 120–277 V. Ensure a qualified electrician installs the device in accordance with local electrical codes.

• Confirm WMS-A102-V-BTBU is the required SKU
• Verify single‑pole circuit and load ≤ 6 A
• Plan to set vacancy/occupancy mode, time‑out and sensitivity during installation
