SoundOff Dumb Siren/Controller

Equip your fleet with bulletproof, uncomplicated acoustic power using a SoundOff Signal Analog Siren and Controller system. In an era of highly complex, software-driven network nodes, many fleets still require the absolute reliability of a traditional, hardwired siren. Commonly referred to in the industry as "dumb" sirens because they do not require a laptop to program, these SoundOff amplifiers (such as the legacy 400 or ETSA series) are legendary for their durability. They utilize simple physical relays, direct 12V triggers, and massive heat sinks to reliably drive 100-Watt or 200-Watt speaker arrays shift after shift.

Key Features & Upfitter Specs

Hardwired Reliability: Operates entirely independent of complex vehicle CAN-bus networks or software configurations, utilizing physical 12V triggers that are exceptionally easy to troubleshoot and repair.
Massive Acoustic Output: Engineered to cleanly drive one (100W) or two (200W) heavy-duty siren speakers, producing standard Wail, Yelp, and Piercer tones that easily clear dense traffic.
Integrated Relays: Many units feature built-in, heavy-duty solid-state relays (e.g., 20-amp circuits) allowing the siren controller to simultaneously power the vehicle's primary lightbar or takedown lights.
Horn Ring Transfer: Easily integrates with the vehicle's OEM steering wheel horn, allowing the officer to tap the horn pad to aggressively cycle through siren tones during a high-speed pursuit.
Thermal Protection: Built with massive extruded aluminum chassis to dissipate extreme heat, ensuring the amplifier will not overheat or shut down during extended Code 3 deployments in summer weather.
