Federal Signal's SST-MV is an electronic siren capable of producing one of four high decibel tone outputs from the same unit.

The Model SST-MV features internal amplification and the tone circuitry to produce four different tones. The user selects from the wail, yelp, horn or temporal slow whoop tone by reconfiguring internal jumpers.

The SST-MV operates on 24VDC, 120VAC or 240VAC. The Type 3R housing is molded from impact-resistant ASA (acrylic-styrene-acrylonitrile) plastic, making it resistant to ultra-violet light and ideal for indoor or outdoor use.

The omni-directional swivel mount system allows the output to be pointed anywhere within a 360º half-sphere.

This electronic siren is UL and cUL Listed.

The Model SST-MV can be used as a stand-alone, high output, audible warning device in any application where voice paging is not required.

Typical applications include emergency warning, start and dismissal, fire alarm, general alarm and evacuation.

Federal Signal's Model SST-MV Electronic Siren is an economical multi-tone siren that is designed to hold up to the rigors of corrosive environments.
