Advanced Warning Flasher – Model AW-2
 |
|
CAD $311.85 This flasher is used in traffic areas where the posted speed limit exceeds 30MPH (50 km/hr).
The main controller switches 2 pole alternate flashing lights on approach to the intersection. This alerts traffic that the signal is about to change from green to red.
This unit incorporates two TF-9-60 two pole flashers. One 2 pole (alternate flashing) for one direction of highway and one 2 pole for the other direction.
Due to conditions such as curves and hills the advance warning lights may be placed different distances from the intersection and may require different start times than the opposite direction. This is the reason for logic 1 and logic 2, which is controlled by the main controller.
An input of 120VAC @ 10mA is supplied from the main controller. Should power fail to, or in the main controller, both advanced warning flashers start flashing. 120VAC power for this unit is supplied independent of the main controller.
