Important Note:
The MPB3400 lights can be used to control “one way “ traffic and “3 way /4 way “ intersections.
The MPB3400 lights come with an “Emergency Quartz back up feature” which can be activated upon request. When an existing radio signal transmission between the lights breaks down, then the lights automatically change over to synchronised emergency quartz mode. And so the lights continue to operate without any noticeable interruptions for vehicle traffic.
