Leviton Decora Wall Switch PIR Occupancy Sensors

Application

Leviton's Cat. Nos. PR150-1L and PR180-1L are designed for standard wallboxes and feature passive infrared (PIR) sensing technology. These versatile devices automatically turn lights ON when a person enters a room and OFF when they leave. They are suitable for a variety of residential applications, including:

• Bathrooms
• Basements
• Garages
• Hallways
• Utility/Laundry Rooms
• Closets
• Pantries
• Dining Rooms
• Kitchens

The PR150-1L installs in place of a single pole switch. The PR180-1L installs in place of a single pole or 3-way wall switch. Both models are compatible with incandescent and fluorescent lighting (Rapid Start Magnetic ballast ONLY).

Operation

The PR150-1L and PR180-1L utilize passive infrared (PIR) detection technology to monitor rooms for occupancy. The sensors automatically turn lights ON when motion is detected and OFF when the room is vacated, saving energy, enhancing convenience, and lowering electric bills. These sensors are designed for indoor use only and are ideal for any room where automatic, hands-free light control is beneficial, such as bathrooms, closets, laundry rooms, and garages.

Automatic ON/OFF Operation

Lights turn ON automatically when motion is detected. If no motion is detected for a user-selected time (ranging from 15 seconds to 15 minutes), the lights will automatically switch off.

Passive Infrared (PIR)

Infrared occupancy sensors are passive devices that detect the movement of heat-emitting bodies. They are installed to monitor areas without physical obstructions that could block the sensor's field of view.

How It Works

Humans naturally emit infrared heat. As a person moves within the sensor's field of view, the sensor detects this change in infrared background and activates the area lights. After the area remains unoccupied for a user-defined period, the sensor automatically turns the lights OFF.

Control and Field of View

Single Pole or 3-Way Control

The PR150-1L offers single pole control exclusively. The PR180-1L provides flexibility with both single pole and 3-way control options. This allows for controlling a single light fixture from two different locations, which is particularly useful for stairways, hallways, and rooms with multiple entrances.

Field of View

The PR150-1L provides a 150° horizontal field of view and covers up to 350 sq. ft. The PR180-1L offers a wider 180° horizontal field of view and covers up to 400 sq. ft. Both sensors are well-suited for a variety of residential and light commercial applications.

Adjustment Options

The PR150-1L and PR180-1L units are equipped with sensitivity and time adjustment controls, allowing users to customize performance for specific installation needs. To make adjustments, remove the wallplate and use a small screwdriver to turn the adjustment wheels.

Light Level Adjustment

• Turning the control towards the ➕ sign adjusts the sensor to turn lights ON in brighter conditions.
• Turning the control towards the ➖ sign adjusts the sensor to turn lights ON in darker conditions.

Time Selection

• Adjust the time selector to set the desired duration for which the lights remain ON. Lights will stay ON for a period ranging from 15 seconds to 15 minutes after the room is vacated.

Features and Benefits

• The PR150 offers a 150° field of view and 350 sq. ft. of coverage, ideal for residential applications.
• The PR180 offers a 180° field of view and 400 sq. ft. of coverage, suitable for larger rooms, home offices, and various light commercial and residential applications.
• An ambient light override feature prevents the sensors from activating lights when sufficient natural sunlight is present.
• A manual override function is available, allowing the device to be used as a standard ON/OFF switch.
• Features an adjustable delayed OFF time interval, settable from 15 seconds to 15 minutes.
• Designed to fit within standard wallboxes.
• The streamlined, popular Decora® styling complements any interior decor and is compatible with other Decora® devices.
• Compatible with Decora Plus™ screwless wallplates and standard Decora wallplates.

Installation

Occupancy sensors should be positioned at least 6 feet away from HVAC registers. Obstructions such as furniture, windows, or glass shower doors may impede the sensor's ability to detect motion.

Specifications

The PR150-1L and PR180-1L are Decora® passive infrared (PIR) occupancy sensors. They detect infrared emissions from human presence and respond by turning ON incandescent and Rapid Start Magnetic fluorescent ballast lighting loads. If no movement is detected after a preset time, the units will switch their assigned loads OFF. Manual override allows for normal ON/OFF operation.

The Cat. No. PR150-1L is designed for single pole applications. The Cat. No. PR180-1L is suitable for both single pole and 3-way applications.
