Application Photos
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.
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
• 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.
• Howler low-frequency tones synchronize with your primary siren tones to penetrate high noise, traffic situations.
• Howler amplifier module uses the primary siren speaker output wires and divides the frequency 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 able to penetrate vehicles, alerting drivers to your oncoming emergency vehicle.
• Built-in timer limits overexposure time, however operators are advised to wear approved hearing protection.
• Two 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 durations: 8-60 seconds maximum).
