Larson Electronics has announced the release of an industrial, explosion-proof VoIP telephone for use indoors and outdoors in hazardous locations. This unit is SIP and PoE compatible, with four configurable AUX inputs and two configurable voltage-free contact outputs. This telephone features a sturdy, cast-aluminum body and a six-foot PVC coiled cord.

The EPPH-230A-VOIP-MOD1-YLW explosion-proof VoIP telephone is PoE compatible for use in areas with limited space. Operators can configure the telephone’s settings using any compatible browser, and an IP converter is not necessary for operation. Connecting directly to a SIP-based (RFC3261) VoIP telephone system is available and real-time alarm reporting is done through email or Syslog. This telephone is rated for use in Class I, Division 1, Groups B, C and D; Class II, Division 1, Groups F and G; and Class III, Division 1 hazardous locations.

Larson Electronics’ explosion-proof telephone features a main keypad with 12 buttons and receiver volume beneath the handset. The NEMA 4X rated enclosure and body of this phone is made of sturdy, copper-free, non-sparking cast-aluminum with an impact resistant, carbon-loaded ABS handset and six-foot PVC coiled cord. This unit is powered using an external 24-48V DC low-voltage power supply and features two 3/4-inch NPT hubs for wiring.

This unit is designed to be wall or column mounted with stainless-steel mounting bolts and is suitable for use indoors and outdoors, mines, refineries, power generation facilities and more.
