Howler™ Siren & Dual Speaker System
Low Frequency Tones for Intersections and High Risk Areas
Whelen's Howler system provides deep, low frequency tones, which are able to penetrate other vehicles, alerting drivers and pedestrians of your approach.
An effective added layer of warning when used with your 100/200 watt siren amplifier. The Whelen Howler consists of two low frequency speakers and an amplifier. The amplifier powers the 2 low frequency speakers and is installed in addition to installing a traditional 100/200 watt siren system.
SWPS Video Demonstration of Whelen Howler Low Frequency Siren:
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. 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.
Features:
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-Lock™
feature and LED indicator. (selection of 8 different tone
