Whelen Howler™

FEATURES • 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 synchronize with your primary siren tones to penetrate high noise, traffic situations. • The 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) .
