EDCO Telecom/Datacom Surge 
Protection Products



The FAS-TEL and FAS-31XT are single pair Telephone or Data Line Protectors that implement advanced two stage hybrid design. These units address over voltage transients with silicon breakover devices, while sneak and fault currents are mitigated with new "PTC' technology which consist of solid state resettable fuses.

FAS-31XT replaces the RJ3 IX jack with a protected version. Four screw terminals are provided to wire the protector in the same manner as a standard RJ3 IX jack. The FAS-3IXT can be used alone or as an accessory to the TS500G or TS-500F AC Power Surge Protector. The TS-500G and TS-500F provide a convenient grounding point for the FAS-31XT I FAS-TEL ground wire.

The FAS-TEL is nearly identical to the FAS-31XT except without the shorting bars. Two screw terminals are provided to connect Telco Line to protector. Protected equipment such as modems, are plugged into female modular jack on the FAS-TEL.
