The SC-411RS-10 14 Elite Force single tone siren is one in a series of sirens developed for smaller spaces with the same options as a full console unit. This new remote siren introduces the new QuickClone™ duplication technology making it easy to transfer option settings from one unit to another without the need for an external computer, ideal for fleet installations. The splash resistant rubberized control head face offers programmable siren tones, light and arrow stick controls and our patented video trigger capability. This unit is small in size, but large in options. Choose between the SC-411-RD which offers Dual Tone or the Single Tone SC-411-RS. Dual Tone: Just like having two sirens going at the same time. And with two distinct tones being produced at the same time, it really captures your attention. The siren may produce Dual Wail, Dual Yelp, Dual Phaser, Dual Air Horn and combine Wail and Yelp at the same time. These tone pairs are programmable for each siren switch position.
