Z-BLOCKER®
In-Line DSL Filter for Residential Alarm Systems

Unique alarm panel filter protects the residential and small business alarm system telephone service (POTS) interface, which dials out to the alarm company in the event of an emergency. Without this protection, alarm panels on telephone lines with DSL may have difficulty reporting incidents.

VoiceLok™ guards your telephone lines and alarm system wiring with a tough, 16 gauge galvanized metal box to cover the telephone box, as well as a 14 gauge steel U-guard to protect the telephone drop wires.
