100W electronic undercover mini-siren with remote switches and intersection clearing feature, Green/red, MS400U

Efficient and Economical Traffic Clearing Mini-Siren MS4000 offers value-packed, reliable performance with effective traffic clearing capability. Reliability is increased, and operating temperature is decreased in the design of the MS4000 with the use of advanced rail circuitry and a low-loss FET design arrangement. Versatile and Compact Siren with Built-In Features MS4000 mini-sirens provides 100 W output and meets Class A requirements when paired with any Federal Signal speaker. The mini-siren can operate from any 12 Vdc 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. Simple Siren Activation MS4000 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, while 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 Built-In Intersection-Clearing Feature A built-in intersection-clearing feature adds effective traffic management capability at potentially hazardous crossings. When the MS4000 is activated and in the WAIL position, depressing the momentary switch to the MANUAL position produces an 8-second Yelp tone. When the MS4000 is activated and in the YELP position, pushing the momentary switch to the MANUAL position produces an 8-second Priority tone. Ideal for Undercover Officer and Volunteer Firefighters The MS4000U is designed especially for undercover police officers and volunteer firefighters. 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.
