TrueAlert Multi-Candela Flashing Light and Siren Warning Device

TrueAlert Multi-Candela Weatherproof Horn/Strobe Fire Alarm Device

The TrueAlert Multi-Candela S4906-0011 is a high-intensity strobe combined with a horn (horn/strobe), operating on 24 VDC, designed for use in Simplex (Johnson Controls) fire alarm systems.

Key Features

• Operates on 24 VDC with regulated circuitry for stable flash output and reduced inrush current.

• Xenon strobe with selectable light intensity: 135, 177, or 185 candela, adjustable via internal jumper.

• SmartSync 2-wire compatibility, allowing horn and strobe to operate on the same circuit.

• ADA compliant, ensuring accessibility for all occupants.

• Durable housing: high-impact, flame-retardant thermoplastic in red or white with clear lens, suitable for wall or ceiling mount.

• Electronic horn (A/V models): energy-efficient, harmonically rich tone, supports steady, Temporal, or March Time (60 BPM) coded operation.

• Synchronized flash at 1 Hz, supporting multiple devices on the same NAC.
