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.
