Frequently Asked Questions

What if I have DSL?

(Digital Subscriber Line) service is used for a high speed Internet connection that uses a secondary channel over one of your existing voice grade telephone lines. WARNING: some types of alarm panels can be damaged by DSL signals, before having DSL installed we recommend you call us to see if your alarm is susceptible to this signal. If it is we can install a special DSL Filter in the panel. This must be done before you have DSL installed to prevent the DSL signal from scrambling your alarm system program.
