The Whelen Howler Low Frequency Siren System offers an added layer of warning for intersections and high risk areas when used with your 100/200 watt siren amplifier. Howler provides deep, low frequency tones, which penetrate other vehicles, alerting drivers and pedestrians of your approach. The Howler is not a replacement to the vehicle’s primary siren; Howler adds a minimum eight second penetrating burst of low frequency siren sound for use in heavy traffic, intersections or other high ambient noise conditions.
  • Howler is an add-on to any 100-200 watt warning siren such as the Whelen 295SL Series. Works with most siren amplifiers
  • Includes one or two speakers for use with Howler amplifier only
  • Works with any sweeping tone, plus Hi/Low and electronic mechanical tone generated by the primary siren

  • Lower frequency reverberating tones are able to penetrate vehicles alerting drivers to your oncoming emergency vehicle
