The lens assembly fits securely into its housing, providing a high integrity notification appliance that is impact and vandal resistant and suitable for a variety of applications. 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. Proper selection of visible notification is dependent on occupancy, location, local codes, and proper applications of: the National Fire Alarm Code (NFPA 72), ANSI A117.1, the appropriate model building code, BOCA, ICBO, or SBCCI, and the application guidelines of the Americans with Disabilities Act (ADA). Additional reference may be found in the Simplex Fire Alarm Strobe Application Guide, publication 574-342.
