Carson Sc-409

$375.45

Designed to power one or two 100-watt speakers, the SC-409 Commander includes a 6 position rotary switch including the new Cycler setting which allows the operator to select the Horn Ring Cycler 2 (HRC2) mode from the rotary switch. There are also two override membrane push button switches for Manual and Air Horn control. A pursuit ready lever/slide switch for up to 60 amps of primary light control has the flexibility to be progressive, non-progressive, or partially progressive, tie auxiliary switches to programmed positions on the lever/slide switch and automatically run the siren tones. The siren is LED backlit and the auxiliary switches turn red when activated. The noise canceling microphone has P.A. override in all positions except Radio with a face mounted volume control knob. The Siren Cutout connects to the door switch and automatically disables the siren when the driver's door opens. The siren is installed using detachable connectors with screw-down terminals for all connections except the lever/slide switch, which utilize heavy-duty screw-down terminals. Each output is individually fused and all fuses are externally accessible. As with all Carson Sirens products, the Commander siren is backed by a no-hassle 5-year limited warranty.
