JL-403C Direct Wire-In Electronic Photocontrol Product Summary The photocontrol JL-403C is applicable to control the street lighting, passage lighting and doorway lighting automatically in accordance with the ambient lighting level.This product is designed with electronic circuits. Its quicker response with time delay of 3-10 seconds offers easy-to-test feature. Especially, model JL-403C provides a wide voltage range for customer applications under almost power supplies.Further, a preset 3-10 seconds time-delay might avoid mis-operation due to spotlight or lightning during the night timeThis product has been listed by UL LLC and is comply with the Standard for Non-industrial Photoelectric Switches for Lighting Control UL773A.Features  Direct wire-in 3-10s Time delay for luminaires protectionSpecificationsInitial Testing

•  It is normal for the SWITCH to take few minutes to turn off when first installed.
•  To test “turn on” during daytime, cover its eye with opaque material.
•  Do not cover with finger because light traveling through fingers may be great enough to
• keep the switch open.
•  Test will take approximately 1 minutes.

* Operation of this switch is not affected by weather, moisture or temperature changes.Ordering Information JL-403CM 18 04 L M N W BC F -IP54
