said by Msradell:said by Bob4:No alarm systems? They still work better with POTS.
Not necessarily, many new installations are now making notifications through Internet connections or cellular connections. Many are even using VOIP phone connections without any problems. The thought that alarm systems require POTS lines is very out of date.
Read carefully: I didn't say alarm systems
require POTS, said they
work better with POTS. POTS has a better uptime (my cable company takes down their phone service at times for maintenance) and there are next to no power failure issues.
My cable company says their phone service is not supported for use with UL burglar or fire alarm systems.
Also, what do the UL standards say about alarm signalling?
