Abrams Quackler Low Frequency Tone Siren Intersection Clearing System (add-on to Any 100-200 Watt Siren System)

The Abrams Quackler Low-Frequency Tone Siren is an effectively added layer of warning for intersections and high-risk areas when used with your 100/200 watt siren amplifier. The Quackler provides deep, low-frequency tones, which are able to penetrate other vehicles, alerting drivers and pedestrians of your approach. Lower frequency reverberating tones are better able to penetrate other vehicles, alerting drivers to the presence of the oncoming emergency vehicle. The Quackler is not a replacement to the vehicles primary siren. The Quackler is an excellent add-on to any 100-200 watt warning siren such as Abrams, Code-3, Whelen, Federal Signal, SoundOff, and Feniex Sirens but also works with most other siren amplifiers. The Quackler adds a minimum eight-second penetrating burst of low-frequency siren sound for use in heavy traffic, intersections or other high ambient noise conditions. Works with any sweeping tone, plus Hi/Low and electronic mechanical tone generated by the primary siren.
