Features

MS4000 is a value-packed, reliable, compact siren with effective traffic-clearing capability. The design of the MS4000 enhances reliability and reduces operating temperature through advanced rail circuitry and a low-loss FET arrangement.

MS4000 mini-sirens provide 100 W output and meet Class A requirements when paired with any Federal Signal speaker. The police 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.

MS4000 can be powered via the vehicle’s power center or directly from its battery. WAIL, Yelp, Priority Siren, Manual, and Air Horn are all standard on the MS4000 siren. Siren activation is made simple with two rocker switches controlling all the siren functions. One switch controls AIR HORN, MANUAL, while the other controls WAIL/YELP. 

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.

The MS4000U is designed 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.

Important Warning for Police Boats and Fire Rescue Boats

It has come to our attention that police boat and fire rescue boat sirens and speakers may subject persons operating those craft to sound pressure levels that can cause permanent hearing loss. We recommend that speakers be located as far forward on the boat as possible, as recommended in the SAE Recommended Practice J1849 “Emergency Vehicle Sirens”. However, unprotected exposures of a sufficient duration to properly located siren speakers can still create a risk of hearing loss.

It is our recommendation that your siren speakers should be relocated and persons operating these craft should wear hearing protection when using the siren system.

Failure to comply with these recommendations may result in temporary or permanent hearing loss to operators and passengers of these vehicles.
