Federal Signal Wide Area Dispersion Speakers are audible notification appliances specifically designed for extensive area coverage with minimal installation effort. These products are configured with full range transducers mounted in a vertical line or line array. This configuration affords the following improvements over typical horn loaded speakers; extremely wide horizontal coverage, improved sound level consistency over an increased coverage area, and drastically improved intelligibility. Wide–Area Dispersion Speakers are ideal for voice messaging, tone generation and live public address. Sealed with powder–coat paint, these units are suitable for use indoors and out.

When mounted properly, the Model WDS80 generates a full power sound level of 80dB at 400 feet and provides the same coverage as four typical industrial speakers. An extension speaker, the Model WDS50, can be added to increase the full power distance to 700 feet.

Power handling for the Model WDS80 is 80 watts with transformer taps at 80, 50, 25 and 12.5 watts. When the extension speaker, Model WDS50, is added, the combined power handling is 130 watts with transformer taps at 130, 80, 40 and 20 watts. These products are adjustable for use in 100, 70 or 25 volt systems.

These products are shipped with all necessary hardware for wall mounting. Kits for pole mounting and I–Beam mounting are sold separately. Also included is the hardware to mount an optional LP3P or Fireball strobe visual signal.
