I have a home alarm wired by a monitoring station. I asked this question and I never seem to get a straight answer.

I want to know what happens if some cuts my phone line and the alarm goes off.

Does the monitoring recieve any problem signal ?

I know the alarm will go off, however my neighbors will just stay in bes ( like I would).

It amazing I can not get an answer to thsi question.

Most residential systems become whats known as a local alarm when the phone line is compromised. What that means is if your phone line is lost due to a burglar or just the phone company your system can only sound its siren and hope your neighbors call the police. Most alarm companies have backup options such as cell phone or radio communications.These backups allow your system to communicate to the central station with out a phone line . This will cost extra but may be worth it for the peace of mind it will give.

cross your fingers that your neighbors call the police
