Federal Signal's SSTX-MV is an explosion-proof electronic siren capable of producing one of four high decibel tones from the same unit. The circuitry is contained in a rugged die-cast aluminum amplifier housing. The unique threaded rear access cover eliminates traditional time consuming bolting patterns. The access cover is also equipped with a braided cable lanyard securing it to the housing whenever the cover is open for installation or maintenance.

The Model SSTX-MV features internal amplification and tone circuitry capable of reproducing one of four different tones. The user selects from the wail, yelp, horn, or temporal slow whoop tones by reconfiguring the internal jumpers.

This unit operates on 24VDC, 120VAC or 240VAC. It is capable of producing up to 108dBa @ 10 feet (118dBa @ 1m).

This electronic siren is UL and cUL Listed for Class I, Division 1, Groups B, C & D.

The Model SSTX-MV can be used as a stand-alone, full output, audible warning device in any explosion-proof environment where voice paging is not required.

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

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