405 Series strobes 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, 60 cd, and 110 cd effective flash intensity. They are fully compatible with Genesis signals.

405 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, or when powered by suitably enabled booster power supplies and control panels.

The flash from 405 Series strobes can be noticed from almost any position in the room, corridor, or large open space. 405 Series strobes are UL 1971 listed with both wall and ceiling cd intensity ratings. This is useful in areas where the Authority Having Jurisdiction (AHJ) permits ceiling-mount strobes.

405 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 terminals that accept up to #12 AWG (2.5mm2) wire.

The strobe front plate is of steel construction finished with durable baked epoxy polyester powder-coat paint.
