Whelen Howler Low Frequency Siren - Universal

Whelen Howler Low Frequency Siren - Universal

Deploy devastating acoustic warning on any custom apparatus with the Whelen Howler Universal Low Frequency Siren System. Heavy rescue trucks, tactical armored vehicles, and specialized commercial fleets cannot rely on standard sirens alone to move traffic. The Whelen Howler provides the massive acoustic upgrade necessary for heavy apparatus. Synchronized with your primary siren, it produces a colossal bass wave that cuts straight through the soundproofing of surrounding civilian vehicles. This universal kit includes flat-mount, heavy-gauge steel brackets designed to be bolted or welded to custom bumpers or flatbed headache racks.

Key Features & Upfitter Specs

• Low-Frequency Penetration: Generates deep bass tones that easily penetrate heavily insulated vehicle cabins and overcome heavy apparatus noise, ensuring your warning signal is felt.
• Primary Siren Synchronization: Operates seamlessly alongside your primary 100/200W siren amplifier, synchronizing with the sweeping or Hi/Low tones to create a massive, multi-layered acoustic wall.
• Timer-Controlled Safety: Includes a built-in safety timer (selectable from 7.5 to 60 seconds) that automatically deactivates the Howler to prevent excessive low-frequency exposure to the vehicle operator.
• Universal Mounting Hardware: This kit includes heavy-duty, flat-mount steel brackets designed for upfitters to secure the massive Howler speakers to custom chassis, flatbeds, or tactical vehicles.
• Selectable Tone Styles: Utilizing Scan-Lock technology, operators can customize the exact frequency style (1/4 tone, 1/2 tone, or composite) to achieve maximum penetration for their specific environment.
