JL-424 Rotating Handle Direction Finding, Zero-Cross+FCC
The photocontrol JL-424 series is designed to automatically control passage lighting and doorway lighting based on ambient lighting levels.
This product features electronic circuits with integrated MCU technology. Its quick response with a 5-second time delay offers easy testing while preventing redundant operation due to spotlights or lightning during nighttime. The device supports midnight sleeping and reburning before dawn functionality.
The optional Z version incorporates zero-cross technology for extended operational life and complies with FCC regulations. JL-424 also provides surge protection up to 235J/5000A.
Frequently Asked Questions
What is the purpose of the rotating handle for direction finding on this device?
The rotating handle allows flexible adjustment of the sensor orientation, enabling accurate direction finding and precise aiming toward the target ambient light source for reliable detection.
How does zero-cross technology work in this photocontrol product?
Zero-cross technology switches the lighting load at the zero point of the AC waveform, reducing arcing, protecting circuit components, and improving overall operation stability and service life.
What does FCC compliance mean for this infrared filtered photocontrol?
FCC certification ensures the product meets electromagnetic interference standards, avoids radio frequency interference with other electronic devices, and is suitable for sale and use in North American markets.
Why is infrared filtering important in this directional photocontrol?
Infrared filtering blocks unwanted IR light interference, prevents false triggering from sunlight or heat sources, and ensures the sensor responds only to effective visible ambient light.
In what lighting applications is this directional photocontrol most suitable?
It is widely used in street lighting, wall packs, floodlights and outdoor fixtures that require accurate directional sensing, stable switching and reliable anti-interference performance.
