Simplex 4903-9432 Horn-Strobe, 75cd White

The Simplex 4903-9432 is a white, 4-wire audible/visible notification appliance combining a piezoelectric horn with a 75 candela xenon strobe, designed for wall mounting on standard single gang, double gang, or 4-inch square electrical boxes. It is part of the TrueAlert non-addressable notification appliance line and can be controlled by conventional reverse-polarity notification appliance circuits.

Key Features:

• 75cd Xenon Strobe: High-intensity strobe output listed to UL Standard 1971, with candela rating clearly marked on the reflector.

• Low-Current Electronic Horn: Draws only 25 mA at 24 VDC, listed to UL Standard 464, with harmonically rich output suitable for coded or steady operation.

• Independent Horn/Strobe Control: 4-wire design allows the horn and strobe to be controlled on separate circuits for applications such as audible escalation sequencing.

• Free-Run or Synchronized Strobe: On-board switch selects free-run flash or synchronized operation with compatible Simplex control panels and flash modules.

• Flexible Mounting: Semi-flush or surface mounting with optional adapters for surface-mounted electrical boxes.
