# AlarmFAS-TEL and FAS-31XT
RJ11/RJ31X Telephone Line

The FAS-TEL and FAS-31XT are single-pair telephone or data line protectors that implement advanced two-stage hybrid design. These units address overvoltage transients with silicon breakover devices, while sneak and fault currents are mitigated with PTC technology which consists of solid-state resettable fuses.

FAS-31XT replaces the RJ31X jack with a protected version. Four screw terminals are provided to wire the protector in the same manner as a standard RJ31X jack. The FAS-31XT can be used alone or as an accessory to the TS-500G or TS-500F AC Power Surge Protector. The TS-500G and TS-500F provide a convenient grounding point for the FAS-31XT/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.
