With the proliferation of DSL for high-speed Internet access in residences and small businesses, alarm dealers and service providers receive an increasing number of reports of interference between their customers. DSL service and alarm systems. When alarm panels have difficulty dialing out and reporting incidents in an emergency, customer service calls increase, customer confidence decreases and company profits can suffer.

  Alarm dealers and service providers have taken various approaches to solve this problem, such as:  Installing a splitter or separate phone line, which is more costly than an Alarm Filter  Installing a standard DSL filter at the alarm panel, which filters DSL signals but does not filter all high-frequency disturbances such as those from a cordless phone. In addition, a standard DSL filter will not ensure the highest possible data rates and prevents the alarm panel from seizing a dial-out line if it is cut or there is an emergency.

  None of these approaches provide a low-cost, reliable solution to the problems created by the coexistence of DSL service with an alarm system.   A Z-A431PJ31X panel filter provides alarm dealers and service providers with a low-cost alarm panel DSL filter that keeps customer service calls down and customer satisfaction up.   This is the only DSL filter in the world designed solely for alarm systems, the Z-A431PJ31X-A isolates high-frequency DSL and HPN (Home Phone Network) signals from low frequency voice and data communication.
