APS Resource’s S.W.A.T. (Secondary Warning Alert Technology) module adds an extra layer of protection for dock operations by visually alerting workers to use caution anytime there is a change in dock status. The module is designed to work in combination with a dock’s LED dock light and vehicle restraint. When the vehicle restraint indicates a change in dock status, the module flashes the interconnected dock light at a rate of 30 flashes per minute (fpm). Compact in design to minimize risk of damage, along with a polymer housing that resist corrosion, the device easily mounts on a loading dock wall next to the vehicle restraint control panel. Featuring its own LED status light to indicate receptacle output status, the module is ETL listed and is approved to work with other LED dock lights.
