Synchronizing Specifications

Synchronizing Circuit Connection:
This is a low voltage, low power customer connection which requires one 22ga twisted pair run between each light. Max length between furthest lights 3000 feet. Up to 100 lights of different voltages can be synchronized.

Synchronizing Circuit Features:
Each light contains its own flash rate timing circuit which operates the lamp automatically and a bi-directional synchronizing circuit which overrides the internal timing circuit when connected to another light. When two or more lamps are synchronized together, failure of any lamp will not prevent other lamps from operating. Lights may be operated from different power sources, that is, a 120VAC unit may be synchronized with a 12VDC unit.
