Model 295HFS Series amplifiers are microprocessor controlled and rated for 100 or 200 watt output.

Standard features include: Radio Rebroadcast, Public Address, Manual, Wail, Yelp, Airhorn, and Piercer tones.

Other Features include:

  • PTT (Push To Talk) switch on unidirectional microphone over-rides all siren functions.
  • All siren functions are backlit in a soft, non-glare green for ease of nighttime visibility.
  • An adjustable bail bracket allows mounting in a variety of positions. 
  • Each model is mounted on a slide out chassis with an integral quick disconnect plug for ease of maintenance or replacement.
  • In 295HFS Models, Si-Test® provides a significant risk management advantage.
    • Two different real time diagnostic tests include: Continuous dynamic testing during normal siren operations and a unique silent test while in the "Radio" mode with the "Manual" button depressed. During either operation, one or both red LED lamps will extinguish instantly upon sensing a siren or speaker(s) malfunction. Si-Test® instantly assures you of proper warning capability and two speaker operation for high risk situations. It also eliminates the need for annoying siren blasts during vehicle inspections or shift changes. Only Whelen offers this "silent" testing, day or night.
