Whelen Howler Low Frequency Tone Siren
The Whelen Howler Low Frequency Tone Siren is an effective added layer of warning for intersections and high risk areas when used with your 100/200 watt siren amplifier. The Howler 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 Howler is not a replacement to the vehicle’s primary siren. The Howler is an excellent add-on to any 100-200 watt warning siren such as the Whelen 295SL Series, but it also works with most other siren amplifiers. 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. Works with any sweeping tone, plus Hi/Low and electronic mechanical tone generated by the primary siren. The Howler low-frequency tones are synchronous with your primary siren tones to penetrate high noise, high traffic situations. The Howler Siren Amplifier module uses the primary siren speaker output wires and divides the frequency down to one of four tone styles.
Selecting tone style and duration is easy. The tone style choices are 1/4 tone, 1/2 tone, a combination of 1/4 and 1/2 tones or the primary siren tone frequency divided by 4-1/2. Select tone duration and tone style using the Scan-Lock button and LED indicators. Select from 8 different tone durations: 8 seconds minimum to 60 seconds maximum. The push on/push off button activates/deactivates the siren, allowing radio transmission to the vehicle without waiting for the unit to time out. Built-in timer limits overexposure time to operator. Operators are advised to wear approved hearing protection. Comes standard with two separate external cancel controls. A positive or negative activation will cancel the tone. The Howler system includes speakers specifically designed for use with the Howler amplifier only. The Howler system will include one or two of these speakers depending upon the vehicle application.
