The Federal Signal SST3GCX-MV Hazardous Location Remotely Selectable Electronic Siren provides high-output audible warning for hazardous location environments that require multiple alarm tones without voice paging. The unit produces three distinct tones—wail, yelp, and horn—from one electronic siren, giving facilities a practical way to assign different audible signals to specific site events, alarms, or operating conditions.
Operators can activate each tone remotely through dry contacts, which makes the SST3GCX-MV well suited for integration into plant alarm systems, emergency warning systems, start and dismissal signalling, and evacuation notification. Its multi-voltage design accepts 24 VDC or 120/240 VAC, helping simplify product selection across different power requirements.
Federal Signal designs the SST3GCX-MV for rugged indoor and outdoor use. The siren uses a spun aluminum speaker cone and projector, while the integrated circuitry sits inside a die-cast aluminum housing. Powder-coated surfaces, dust- and moisture-proof gaskets, Type 4X protection, IP66 enclosure performance, and IP69K compliance help the unit withstand demanding industrial environments.
Available Canada-wide through Westech Industrial, the SST3GCX-MV can also fit into broader safety, fire and gas, or instrumentation projects. Westech supports customers with product selection, service support, system upgrades, and custom fabrication capabilities when projects require integrated equipment, fabricated assemblies, or site-specific solutions.

Description
Three Remotely Selectable Alarm Tones
The SST3GCX-MV produces wail, yelp, and horn tones from one device. This helps facilities use one siren for multiple warning needs. Operators activate each tone from a remote point using dry contacts. As a result, teams can assign different tones to different site events. For example, one tone may support general alarms. Another tone may support evacuation or process-related alerts.
High-Output Audible Warning
This hazardous location electronic siren delivers strong sound output for industrial warning applications. The unit produces up to 110.5 dBA at 10 feet. It also produces up to 120.5 dBA at 1 metre. Therefore, it helps facilities improve audible notification in noisy operating areas. The three-tone output also supports clear communication during urgent events.
Multi-Voltage Design
The SST3GCX-MV accepts 24 VDC, 120 VAC, or 240 VAC power. This flexibility helps simplify product selection across different sites. In addition, facilities can standardize on one model for various electrical requirements. This can reduce confusion during procurement, installation, and future replacement planning.
Built for Hazardous Locations
Federal Signal built the SST3GCX-MV for demanding hazardous location applications. The unit carries UL and cUL listings for Class I, Division 2 locations. It also supports Class II, Division 2 and Class III locations. Therefore, customers can use it in areas where approved audible signalling equipment matters.
Rugged Indoor and Outdoor Construction
The siren uses a spun aluminum speaker cone and projector. It also uses a die-cast aluminum housing for the integrated circuitry. Together, these materials support reliable performance in harsh industrial environments. In addition, powder-coated surfaces help protect the unit from environmental wear. Dust- and moisture-proof gaskets add further protection against challenging site conditions.
Weather-Resistant Enclosure Protection
The SST3GCX-MV provides Type 4X and IP66 enclosure protection. It also meets IP69K compliance. Because of this, the siren suits indoor, outdoor, and washdown-prone areas. Facilities can use it where weather, dust, and moisture exposure create ongoing challenges.
Flexible Mounting and Sound Coverage
External mounting tabs help installers mount the siren on flat surfaces. In addition, installers can adjust the projector for the required sound direction. This helps direct the warning signal toward key operating areas. For best results, teams should keep the front of the siren clear of obstructions. Overall, this hazardous location electronic siren gives facilities strong output, flexible tone selection, and rugged construction in one unit.
Applications
The Federal Signal SST3GCX-MV suits industrial and hazardous location environments that require a stand-alone audible warning device with multiple tone options. Typical applications include emergency warning, start and dismissal signalling, general alarm notification, evacuation alarms, and facility-wide audible alerts where voice paging does not need to form part of the warning system.
This siren can support fire and gas systems, industrial process areas, plant safety systems, manufacturing facilities, oil and gas sites, chemical and petrochemical facilities, power generation sites, water and wastewater plants, and other industrial environments that require hazardous location audible signalling.
