Title 24 has been updated for 2019. Western presents an ongoing series, presenting the updates in an easy-to-understand fashion. This is Part 4.

Exploring the Updates to Title 24: Fourth in a Series

Occupancy Sensors

This is the fourth in a continuing series of insights into the California Title 24.

Western’s team of lighting and controls experts aim to help you simplify the process of ensuring your projects meet the new Title 24 requirements.

Over the next few months, we’ll be expounding on all of the most relevant new requirements in our new series called "Breaking the Code." The goal is to help you understand the all of the most important changes for 2019’s Title 24 for both residential and commercial applications.

Occupancy Sensors, Vacancy Sensors, Dimmers

Minor modifications have been made to the lighting controls requirements to maintain consistency with the requirements for dimmers and vacancy sensors.

1. All luminaires installed with JA8-certified light sources with dimming capability are required to be controlled by a NEMA SSL-7A-compliant dimmer unless they are controlled by a vacancy sensor or an occupancy sensor.

2019’s Title 24 standards tell us that occupancy sensors can be installed for meeting the vacancy sensor requirement of the residential lighting standard as long as the occupancy sensor is configured to operate in the manual-ON and automatic-OFF mode.

Dimmers and vacancy sensors are not required for any luminaires located in hallways or in closets less than 70 square feet.

The new standards also state that occupancy sensors can be installed for meeting the vacancy sensor requirement of the residential lighting standard – as long as the occupancy sensor is configured to operate in the manual-ON and automatic-OFF mode.

Reminder: The following residential spaces are required to have at least one luminaire in the space to be controlled by an occupancy or vacancy sensor: Bathrooms, Garages, Laundry Rooms, Utility Rooms.

Passive infrared vs. Dual-technology: Lutron offers Maestro occupancy/vacancy sensor switches in passive infrared(PIR) or dual-technology sensing models. Both technologies provide coverage for major, minor and fine motion, making either option ideal for most residential and commercial applications. For applications where very fine motion activities such as typing are most common, the dual-technology sensor is the better solution.

Western Recommends:
Lutron Maestro Dimmers and Occupancy Sensors

The Lutron Maestro Dimmer provides an easy-to-operate tap switch that turns lights on/off to your favorite light level. Use the rocker dimmer to adjust lights manually. The delayed fade-to-off feature gives you 10-60 seconds to leave the room. Combine with Maestro companion dimmers to control a single light from up to 10 locations. 

Lutron Maestro 0-10V Dimmer Sensor combines 0-10V dimming and PIR sensing into one simple, cost-effective solution. Lutron uses XCT sensing technology and smart, adaptive settings to provide reliable sensing and optimized dimming performance. Installation is a snap with mis-wire alerts, no neutral required, and easy adjustable settings.

Dual Technology Occupancy/Vacancy Sensor Switch: Automatically switches lights on and off to provide convenience and energy savings. This product controls 6A at either 120 or 277V.

Lutron Wireless Occupancy Sensors: Lutron’s wireless occupancy/vacancy sensors automate the switching and dimming of lights without having to disrupt the aesthetic of keypads and dimmers.
