The Simplex 4906-9101 is a non-addressable, 24 VDC wall mount strobe from the TrueAlert Multi-Candela series. The housing is red thermoplastic with white FIRE lettering and a clear lens — one-piece assembly including the lens, mounting to a single gang, double gang, or 4-inch square standard electrical box. Strobe intensity is field-selectable via a jumper plug inside the housing: 15, 30, 75, or 110 candela. A yellow flag with black lettering shows the selected intensity from the side of the lens without removing the cover. Flash rate is 1 Hz (60 flashes/minute). Up to 35 synchronized strobes can be loaded per NAC circuit.
