Howler Low Frequency

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.

* The Howler is an add-on to any 100-200 watt warning siren such as the Whelen 295SL Series. Works with most Siren Amplifiers. Includes 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.
* 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 three frequency bands via dip switch. Selections are 1/ 4 tone, 1/ 2 tone or a composite of 1/ 4 and 1/ 2 tones.
* Lower frequency reverberating tones are better able to penetrate other vehicles, alerting drivers to the presence of the oncoming emergency vehicle.
* 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.
* Two separate external cancel controls, standard. A positive or negative activation will cancel tone.
* Select tone duration and tone style via easy Scan-Lockâ„¢ feature and LED indicator. ( selection of 8 different tone durations: 8-60 seconds maximum)
