DSL Broadband Internet services will interfere with your security system. A special filter is required for all monitored security systems that share a telephone line with DSL internet services. Your internet services may also be degraded if this filter is not installed.

 Please note that this filter is not included in the "self-installation" kit sent to you by your DSL service provider.
