Manufacturer Part #: 403-7A-R


Edwards 403 Series Bell-Strobe Plates are specially designed for use with compatible life safety communication and control equipment to alert the hearing impaired of a life safety event. Strobes are available with 15 cd, 15/75 cd, 30 cd, and 110 cd effective flash intensity. They are fully compatible with Genesis signals. As part of the Enhanced Integrity line of products, 403 series strobes exceed UL synchronization requirements (within 10 milliseconds other over a two-hour period) when used with a separately-installed G1M Signal Master or SIGA-CC1S Synchronization Module. The flash from 403 series strobes can be noticed from almost any position in the room, corridor, or large open space. Light dispersion is controlled with a specially shaped reflector that directs a minimum of 12 per cent of rated light output above and below the strobe, and a minimum of 25 per cent of rated light straight out both sides. 403 Series strobes are designed for 16 to 33 Vdc operation and must be connected to signal circuits that output a constant (not pulsed) voltage. A diode is used to allow full signal circuit supervision and polarized connections are made to 7” (175 mm) wire lead. The rugged steel plate with smooth bevelled edges is finished in a durable, high quality, baked red epoxy polyester powder-coat.
