Federal Signal FB24ST-024A FB24ST Series Fireball Supervised Strobe Warning Light, 24VDC, 4-Wire, In-Rush Limited, Amber

Built for dependable, low-interference visual notification in fire, industrial and security applications, the Federal Signal FB24ST-024A Fireball Supervised Strobe delivers clear, maintenance-friendly alerts where monitoring and rapid response matter. The FB24ST series features a 24VDC in-rush limiting PCB that reduces electrical interference with in-rush sensitive devices and improves compatibility with modern control panels. Its four-wire supervised design with an integrated supervisory diode makes it simple to integrate into fire alarm and monitored security circuits.

With a 1,000,000 peak candela (300 effective) output and a long-life 10,000-hour strobe tube, the unit provides highly visible signaling for emergency, process status, and surveillance notification. Built to withstand demanding environments, the strobe is housed in a Type 4X/IP66 enclosure (IP69K compliant) with a corrosion-resistant epoxy finish and vibration-resistant construction. Installation is straightforward using the integrated 1/2-inch NPT pipe or surface mount, and the twist-off dome allows fast serviceability.
