MS4000U Mini Siren

 MS4000U can be powered via the vehicle’s power center or directly from the vehicle’s battery. WAIL, Yelp, Priority, Manual, and Air Horn are all standard on the MS4000.Two rocker switches control all the siren functions. One switch controls AIR HORN, MANUAL, and the other controls WAIL/YELP. The AIR HORN/MANUAL switch rests in the neutral (center) position and activates a function when momentarily placed into the up and down position. The WAIL/YELP switch is a three-position switch with the center position being neutral.

The MS4000U Siren functions are activated in the same manner as the standard MS4000, but the MS4000U mini-siren is activated with switches mounted on a small, remote switch panel.

MS4000U mini-sirens provide 100-watt output and meet Class A requirement when paired with any Federal Signal speaker. The mini-siren can operate from any 12-volt negative ground vehicle electrical system. It is protected against failure models, including reversed polarity, by a fuse that can be replaced without tools.
The MS4000 series comes with its own bracket and can be mounted virtually anywhere due to its compact size and lightweight construction. 

 Years of design and manufacturing experience have made Federal Signal the leader in the electronic siren marketplace. Reliability is increased and operating temperature is decreased in the design of the MS4000 with the use of advanced rail circuitry and low-loss FET design arrangement.

 The Federal Signal AS124 speaker uses advanced housing material and field replaceable Neodymium drivers to provide an effective, high-quality sound. The AS124 is an affordable 100-Watt speaker solution that does not compromise sound output. The AS124 speaker housing is molded from composite plastic — 30% glass-filled PET (polyethylene terephalate). This high-strength composite is a chemical resistance material to maintain rigidity at high temperatures. The driver component of the AS124 is made of a Neodymium magnetic material. Neodymium is a strong, efficient driver material. The AS124 meets SAE, CCR, Title 13 and Class “A” specification requirements for sound output.
