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.

Excelsus alarm filters are available through licensed alarm service providers and security industry distributors like Pro-Comm. Cost is $85.00 installed and tested or $23.75 plus shipping and handling. Order Now
