Rotating Sirens

Provide clear and powerful warning utilizing an oscillating directional speaker at distances approaching and exceeding one mile. Whelen’s VORTEX™ and WPS-4000 Series design features a vertical stack of high-gain radial horns that enter into a single projector, providing a controlled sound column of unequalled power and clarity. The economical HORNET™ utilizes a single directional speaker design. All speakers oscillate throughout 360°, permitting a hard- wired connection between the system’s speaker drivers and power amplifiers, avoiding the destructive effects of brush ring commutator connections found on rotating sirens. All models include a complete speaker and rotor assembly with 50 feet of speaker and rotor cable and an electronics assembly contained within a natural finish aluminum cabinet. Standard warning tones provided are designed to operate in the highly effective, low frequency range for the most efficient and powerful warning at distances from the system.
