INSTALLATION and CONNECTABILITY
To provide flexibility and potential for growth, Guardian
telephones are easily and economically connected to any
telephone network by standard wiring and components.
Voice quality is unaffected when phones are connected
within 15,000 feet (~ 4,600 meters) of a main telephone
switch accepting single line telephones. Maintaining
safety standards may require use of wiring conduits
or other considerations.
Guardian’s WRT Series Telephones are
weather resistant and deliver reliable
communications under adverse conditions.
Specially designed to provide reliable
service in outdoor environments, WRT
Series Telephones resist moisture, dust
and corrosive chemicals.
