The SA-365 Defender Siren

Emergency Vehicle Siren, Fire Rescue Siren, and Console Mount Siren That Always Answers the Call

SA-365 DefenderSimplicity is the key to the SA-365 Defender. Simple to install, simple to operate and simple to afford! At first glance, you might notice that the SA-365 closely resembles the existing Carson SA-360 Defender. The SA-365 has, in fact, replaced the SA-360, but has not replaced the features and functionality that made it an industry leader, such as, three position rocker switches to select between a siren wail, yelp, and phaser, or optional Two-Tone/HiLo siren tones with Manual and Air Horn override. The siren also features Instant-On and Horn Ring Cycler 2 (HRC2) functionality that enables the driver hands-free control of the siren by cycling through the tones with the vehicle's horn.

SA-365 Defender Siren Optimizes Vehicle Compartment Space

Where the similarity between the two models ends is in chassis size. The SA-365 has been engineered with a reduced internal electronics footprint, resulting in a chassis that is almost 50% smaller than that of the SA-360. Additional features include removable terminal block wiring for simple, plug-in connection to the amplifier, and external DIP switches for easy siren customization. Its basic, straightforward design and compact size make the SA-365 an ideal choice for law enforcement, security and volunteer firefighter applications where mounting space is limited.
