Principles of
Operation :
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.

Product Information :
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.
