• This mode will only synchronize Wheelock horns, horn strobes, and strobes with the synchronization capability.
• If only strobes are connected to the POWERPATH outputs, the initiating input to IN2 is not required.
• When synchronized horns are used on the two wire output of the POWERPATH, IN2 must be connected as shown or the
horns will not operate.
