Description
Broadcast voice pages and alarm signals safely in explosive-atmosphere environments with the Valcom V-1039A, a 7-watt UL-listed explosion-proof paging horn rated for Class I Groups C and D gas atmospheres, with solid metal housing, weather resistance, and an included V-1092 volume control.
The Telecom Spot Expert Review
Class I Group C and D gas atmospheres include ethylene, cyclopropane, hydrogen sulfide, and similar flammable gases encountered in petrochemical facilities, gas processing plants, water treatment facilities, and industrial chemical environments. Standard electrical equipment creates an arc or spark ignition risk in these locations — the V-1039A's explosion-proof enclosure is engineered to contain any internal arcing within the housing and prevent it from igniting the surrounding atmosphere. UL listing for Class I Groups C and D is the documented certification required by NFPA 70 and NEC for electrical equipment installed in these hazardous locations. At 7 watts with a solid metal housing, it delivers enough output to be heard above industrial ambient noise without compromising the enclosure integrity required for the hazardous location rating. The included V-1092 volume control allows level adjustment from the control side of the installation without accessing the horn itself. One-way operation keeps it focused on the paging and alarm notification use case where command and control must flow from the paging station outward.
