'alarm systems' work one of two ways
1) the house panel CALLS the 'Central Monitoring Station' saying 'house is being broken into'.
2) the Central Monitoring Station CALLS the house,often, to ask for a 'status update'
#1 is NOT truly a secured, monitored system. if you cut the 'phone line', panel can't call out, CMS assumes everything is normal.
#2 IS the better way to do it . CMS asks for status, often, if all 'green' , great. IF 'loss of communications' that is treated as 'trouble/possible break in', guy automatically sent to see WHAT and WHY.
In the systems I designed, I could tell BELL CDA where, within reason , THEIR phone line was open or grounded, even whether it was 'tip' or 'ring' that had the fault and some lines were 15 miles long.
