Federal Signal Mini Undercover Siren MS4000 Mini Undercover Siren
Hide away version of the MS4000 mini-sirens which 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 an easy to replace fuse. Wail, Yelp, Priority, Manual, and Air Horn are all standard on the MS4000 and are controlled by rocker switches.
The Undercover version features a separate mini toggle switch panel which enables the siren box to be mounted remotely, for using less dash space.
Recommend speaker is Federal's AS124 100W speaker (FSC-750501)
