Product Description

Federal Signal MS4000U undercover Mini-Siren. 100-watt electronic undercover mini-siren with remote switches and intersection clearing feature. The MS4000U is designed especially for the undercover officer and volunteer firefighters. Siren functions are activated in the same manner as the standard MS4000, but from switches mounted onto a small, remote switch panel. 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 with the use of advanced rail circuitry and low-loss FET design arrangement. Efficiency and versatility are built-in features of the MS4000U. This mini-siren comes with its own bracket and can be mounted virtually anywhere because of its compact size and lightweight construction. MS4000U mini-sirens provide 100-watt output and meet Class A requirements when paired with any Federal Signal speaker. This mini-siren can operate from any 12-volt negative ground vehicle electrical system. It is protected against failure modes, including reversed polarity, by a fuse that can be replaced without tools. The MS4000U can be powered via the vehicle's power distribution center or directly from the vehicle's battery. Wail, Yelp, Priority, Manual, and Air Horn are all standard on the MS4000U. 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 or down position. The WAIL/YELP switch is a three-position switch with the center position being neutral. A new, built-in intersection clearing feature adds effective traffic management capability at potentially hazardous crossings. When the MS4000U is activated and in the WAIL position, depressing the momentary switch to the MANUAL position produces an eight-second Yelp tone. When the MS4000U is activated and in the YELP position, depressing the momentary switch to the MANUAL position produces an eight-second Priority tone.
