The ESP Communications System is powered by a standard nine-volt alkaline battery (not included). Continuous service life of the battery is approximately 14 to 18 hours. A super-bright LED indicates that the unit is activated.
The battery is removed and installed by loosening or tightening two thumbscrews, which secure the battery cover. If the battery is installed incorrectly, the LED will not light when the unit is turned on.
The ESP System's water-resistant housing permits washing of the respirator facepiece as instructed in the respirator manual without removing the communications device.
Depending on user preference, the ESP System can be purchased as a conversion kit or already installed in the Ultravue Facepiece.
The ESP Communications System is designed for compliance with NIOSH and NFPA-1981, 1997 edition. It's rated as intrinsically safe for use in Class I, II, and III, Division 1, Groups A, B, C, D, E, F, and G hazardous locations.

A battery-powered, self-contained communications unit for use with the Ultravue full-facepiece. Provides hands-free voice amplification for local, short-range communication.
The ESP unit consists of a microphone and speaker, housed within a waterproof, injection-molded, high-strength polymer case. It weighs only eight ounces. It is especially useful in the chemical and nuclear industries and other environments where full-facepiece air-purifying respirators must be worn and where communication between workers is important.
