The SA-361 Defender Siren

Police Siren, Motorcycle Siren, Rescue Vehicle Remote Siren That Always Answers the Call

SA-361 DefenderThe SA-361 Defender remote siren has been redesigned with a new look and added functionality! The improved Defender combines the same simple operation, reliable performance and full-featured siren options as the original SA-361, but in a smaller, more compact amplifier. Size and user-friendly serviceability were the motivating factors in the redevelopment of this industry favorite. These key factors were achieved through the addition of terminal block wiring, which offers simple, plug-in connection to the amplifier; and the reduction of the internal electronics footprint resulting in a smaller amplifier with more versatile installation capabilities.

SA-361 Defender Siren Always Answers the Call

The SA-361 Defender Siren is designed to work with a single 100-watt siren speaker and includes a mounting bracket, short circuit, high voltage and reverse polarity protection systems and an output indicator light for diagnostic purposes.

The siren also features external DIP switches for easy siren customization, and the Horn Ring Cycler 2 (HRC2) function that enables the driver hands-free control of the siren by cycling through the tones with the vehicle's horn. As with all Carson Sirens products, the SA-361 Defender is backed by a no-hassle 5-year limited warranty.
