Federal Signal FB24ST Fireball Supervised Strobe Warning Light, 24VDC, 4-Wire, In-Rush Limited, Red

For dependable visual alarm performance in fire, security and industrial monitoring applications, the Federal Signal FB24ST supervised strobe warning light delivers a durable, service-friendly solution. This supervised strobe light is engineered for system compatibility — the 24V DC input and in-rush limiting PCB minimize electrical interference with sensitive control and surveillance equipment, while the four-wire supervisory diode provides continuous circuit supervision for fire alarm panels. With 1,000,000 peak candela (300 effective) output and a 10,000-hour strobe tube, the FB24ST provides bright, long-life visual signaling that stands out in noisy, high-traffic environments. Built to last, the unit features a Type 4X, IP66 and IP69K-rated enclosure plus black epoxy corrosion resistance and vibration-resistant construction for indoor or outdoor use. Installation is simple with integrated 1/2" NPT pipe and surface mount options and an easy twist-off dome for quick service.
