Federal Signal's brightest and most compact strobe light, this Supervised FireBall emits a powerful "lightning bolt" flash of light. Approximately five inches tall and four inches in diameter and rated at 300 effective candlepower, the FB24STHI is economical and effective. The Fireball is available in 24VDC, this model is UL Listed and CSFM (California State Fire Marshal) Approved.

The FB24PSTHI features a voltage in–rush limiting PCB design that provides greater compatability with control systems and panels and less electrical interference with in–rush sensitive devices.

The FB24STHI features a clear dome that twists off easily for quick dome and lamp replacements. The newly redesigned base features an integrated 1/2" pipe mount boss as well as the three holes required for surface mount configurations. Black epoxy paint is electrostatically applied to the base for superior corrosion resistance. The Fireball dome and base design provides a watertight, dust–tight and corrosion resistant Type 4X rating.

The Fireball FB24STHI contains a supervisory diode and four wire leads, for use in fire alarm applications. This strobe is UL 1971 listed, for hearing impaired applications.
