Zero Cross+FCC Direct Wire In Digital Photocontrol Passage Lighting Time Delay Feature
The JL-423C / JL-423CM Zero-cross+FCC Direct Wire-In Digital Photocontrol is designed for automated control of passage lighting and doorway lighting based on ambient light 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 from spotlights or lightning during nighttime. The control supports midnight sleeping and reburning before dawn functionality.
The optional Z version incorporates zero-cross technology for extended operational life while conforming to FCC regulations. Additionally, the JL-423CM model provides surge protection up to 235J/5000A.

What is a Zero Cross+FCC direct wire in digital photocontrol for passage lighting?
It is a digital photosensor designed specifically for passage lighting systems, featuring direct wire installation, Zero Cross technology for stable operation, FCC certification for electromagnetic compliance, and a built-in time delay function to optimize passage lighting control.
What does Zero Cross technology do in this digital photocontrol?
Zero Cross technology ensures the photocontrol switches on/off at the "zero crossing" of the AC power cycle, reducing electrical arcing, extending the lifespan of connected lighting fixtures, and ensuring smooth, interference-free operation for passage lighting.
Why is FCC certification important for this direct wire photocontrol?
FCC certification means the photocontrol meets strict electromagnetic interference (EMI) and radio frequency interference (RFI) standards, ensuring it does not disrupt other electronic devices and is compliant for use in North American markets.
What is the time delay feature used for in passage lighting photocontrol?
The time delay feature allows the photocontrol to keep passage lights on for a set period after the ambient light level rises (e.g., dawn) or after motion is detected, ensuring safe passage and energy efficiency in hallways, corridors, and other passage areas.
