SigCom TMH-120G Hazardous Location Tone Signaling Speaker
The SigCom TMH-120G is a self-amplified tone signaling speaker engineered for Class I and Class II Division 1 hazardous locations, including petrochemical facilities, refineries, grain handling operations, and other environments where explosive atmospheres may be present. The explosion-proof rated housing of the TMH-120G meets the stringent requirements for hazardous area notification.
What sets the TMH-120G apart from standard amplified speakers is its built-in tone generation capability. Temporal pattern, March Time, and other selectable alarm tones are generated internally, eliminating the need for an external tone source and simplifying system design in hazardous areas where additional equipment means additional risk.
Powered by 120V AC, this gray unit integrates into existing AC-powered emergency notification circuits. It supports both tone-only and voice-plus-tone signaling, providing maximum flexibility for HazLoc mass notification system designers. The SigCom TMH-120G delivers explosion-proof reliability and intelligent tone generation in a single rugged package.
