To protect against transient voltages and currents, solid state secondary
protectors must be installed if there is outside wiring, and on all DID and
E&M Tie lines. These protectors, which contain fast semiconductors in
addition to fuses, shall comply with the requirements for secondary protectors
for communication circuits, UL 497A. Care must be taken to ensure that they
are very well grounded to a reliable earth ground. Recommended protectors
are available in the fast Series 6 line from ONEAC Corp., Libertyville, Illinois
60048, (800) 327-8801. Install and test the secondary protectors precisely to
the installation instructions of the manufacturer.
