Federal Signal’s innovative 650 series siren allows for all sound and light functions to be enabled by rubberized buttons located on the unit’s compact (4.5" L x 2" W x 1" H) and easy-to-use microphone control head. The advanced microprocessor-based amplifier exemplifies Federal Signal’s commitment to remain today’s unmatched leader in the field of siren technology.

Compact Microphone Controller
All siren and light functions are located on the 650 series microphone. Ten rubberized buttons control three progressive “slide switch-like” positions, on/off, PA, Air Horn, Peak-and-Hold, tone switching, and up to 30-amps of additional auxiliary power. The microphone controller “snaps” into a small plastic remote junction box where PA volume and a secondary on-off switch are located, then runs directly to the 650 series amplifier. Both of these connections are plug-and-play via eight conductor telephone jacks. An innovative microphone holder that can rotate and pivot to almost any angle allows for a wide variety of installation possibilities.

Advanced Amplifier Design
The 650 series remote siren provides 100 W speaker output and can operate from any 12 Vdc negative ground vehicle electrical system. It is short circuit protected and can be powered through an installed power distribution center (PDC), or directly from the vehicle’s battery. Reliability and efficiency are maximized by the use of advanced microprocessor-based technology. The 650 Series amplifier comes equipped with (8) 10 A light or auxiliary relay connections, is horn ring control ready, and has it’s own bracket mount to allow for quick and easy removal or replacement. Also provided is a 16.5-ft wire harness and all necessary hardware.
