I can’t get my alarm system monitored without knowing if it is set up to a phone line. How do I do that?

just try to generate an alarm and check if your telephone line is ” busy ” during the alarm.
The installer should have handled that. Just connect the alarm into a working phone jack.
Open the Alarm Box
You should see a "phone switch" box or something similar.
Plug a phone. If you listen to a dial tone, you are connected.
inside the alarm panel box, there should be a 2 inch square, ivory colored, RJ31x type phone jack. The jack should have four wires connected inside the jack, pins 1,4,5,&8. 4&5 go to the network interface connector, pins 1&8 go to the rest of the phones in the house.
The jack on the front is an RJ45 (wide, looks like a network/ethernet jack).
To test, plug the alarm panel into the RJ31x. Set off the alarm. The controller should seize the phone line, disabling all the phones in the house.
If it does not, you will need to have someone wire the RJ31x.
Not too many people know how to do that. Many BELL Tele guys cannot wire a 31x to save thier lives. Bell calls the actual jack a 635 type jack. The USOC code is RJ31 thru RJ35.
