Synchronized Strobes. When multiple visible appliances and their reflections can be seen from one location, synchronized flashes reduce the probability of photo-sensitive reactions. Flash synchronization modules are available to control the observed flashes of synchronized flash models at a rate of 1 Hz using the existing two wire circuit (US patent no. 5,559,492). Standard models will operate in a free-running mode even when connected to a synchronized NAC. (Refer to page 2 for model numbers.) The efficient switching regulator electronic design provides over-voltage protection for the flash discharge capacitor and ensures consistent visible notification output . Strobe Selection.
