The Gentex AVSM synchronization control module is designed to provide an easy way to synchronize multiple horns, strobes and horn/strobes using only two wires in instances where a synchronized flash is required. When synchronizing multiple horns and horn/strobes there is the ability to silence the horn while allowing the strobes to continue to flash.

Incorporating the control module as shown in the following diagrams, the control module will control the power to the signaling device to produce synchronized operation.
