Setup and Installation
Before beginning installation, ensure the power supply to the installation area is turned off at the circuit breaker to prevent electrical shock.

- Fixture Attachment: Securely attach the fixture to the mounting surface using appropriate hardware.
- Adjust Lamp Heads: The three lamp heads are tool-free adjustable. Position them to direct light to your desired areas.

Operating Your Security Light
- Dusk-to-Dawn Operation: The integrated photocell automatically turns the light on at dusk and off at dawn, providing continuous illumination during nighttime hours.
- Motion Activation: When motion is detected within the 240-degree, 70-foot adjustable range, the light will activate at full brightness. The duration the light stays on after motion detection can be adjusted.
- Manual Override: To keep the light on continuously regardless of motion or ambient light, use the manual override feature. Typically, this is activated by quickly cycling the wall switch (OFF-ON-OFF-ON). Refer to the detailed instructions included in the product packaging for specific manual override procedures.
- Dualbrite Two-Level Lighting: This feature allows the light to operate at a lower, ambient brightness level during the evening and then switch to full brightness upon motion detection.
- Creep Zone: The motion sensor is designed to detect movement directly below the fixture, often referred to as the 'creep zone', ensuring comprehensive coverage.
Maintenance
The Heath Zenith HZ-5872-WH security light is designed for minimal maintenance. Regular cleaning will help maintain its appearance and performance.
- Cleaning: Periodically wipe the fixture and frosted lamp lenses with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the finish or plastic components.
- LED Technology: This fixture utilizes integrated LED technology, meaning there are no bulbs to replace.
Troubleshooting
If your security light is not functioning as expected, consider the following common issues:
- Light Not Turning On: Ensure the power supply to the fixture is active. Check the circuit breaker. Verify that the photocell is not obstructed, as this can prevent dusk-to-dawn operation.
- Motion Sensor Not Activating: Confirm the sensor is aimed correctly and not obstructed. Adjust the sensitivity setting if necessary. Ensure the light is not in manual override mode.
- Light Stays On Continuously: Check if the light is in manual override mode. If so, cycle the power switch to return to automatic operation. Ensure the motion sensor is not continuously detecting movement (e.g., from tree branches or passing traffic).
- Light Flickers: Check all wiring connections for secure contact. Ensure the voltage supply is stable.
If these steps do not resolve the issue, contact customer support for further assistance.
