Federal Signal's SSTX3-MV is an explosion-proof electronic siren capable of producing three high decibel tones from the same unit. The integrated circuitry is contained in a rugged die-cast aluminum 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 SSTX3-MV features internal amplification and tone circuitry capable of reproducing three tones. The user activates each tone (wail, yelp or horn) with dry contacts from a remote point.
This unit operates on 24VDC, 120VAC or 240VAC. It is capable of producing 108dBa @ 10 feet (118dBa @ 1m).
This electronic siren is UL and cUL Listed for Class I, Division 1, Groups B, C & D.
The Model SSTX3-MV can be used as a stand-alone, full output, audible warning device in any explosion-proof environment where multiple tones are needed but voice paging is not required.
Typical uses include emergency warning, start and dismissal, fire alarm, general alarm and evacuation.
Federal Signal's Model SSTX3-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.
