✔️ 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 mil liseconds other over a two-hour period) when used with a separately installed G1M Signal Master or SIGA-CC1S Synchronization Module.
- Flash 403 series strobe can be noticed almost any postion in the room, corridor, or large open space. Light disperion is controlled with a specially shaped reflector that directs a minimum of 12% of the rated light output above and below the strobe and a minimum of 25% of the rated light straight out on 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 superv sion 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

Application
Bells
Suggested sound pressure levels in each signaling zone for alarmor alert signals are at least 15 dB above the average ambient sound level or 5 dB above the maximum sound level having a duration of at least 60 seconds, whichever is greater, measured 1500mm above the floor. The average ambient sound level is the RMS, A-weighted sound pressure measured over a 24-hour period.
Strobes
Edwards strobes are UL 1971-listed for use indoors as wall-mounted public-mode notification appliances for the hearing impaired. Prevail-ing codes require strobes to be used where ambient noise conditions exceed specified levels, where occupants use hearing protection, and in areas of public accommodation.
