Usually leaves our warehouse the same business day.
The Excelsus Z-A431PJ31X-A Z-Blocker is an alarm panel DSL filter designed to remove phone line interference in DSL-equipped residences.
With more homes and small businesses using DSL for high-speed internet access, interference between Access Control and DSL modems has become a recurring problem. The Z-Blocker helps filter that interference from the access control system without disrupting alarm panel communication during an emergency.
The Z-Blocker, a DSL filter designed solely for alarm systems, isolates high-frequency DSL and HPN (Home Phone Network) signals from low frequency voice and data communication even during high frequency disturbances not related to DSL, uninterrupted DSL/HPN communication during alarm panel line seizure, and incident reporting.
