Serious answers only, please. Home alarm system problem........?

We have a home security system that was installed 13yrs ago. The company is out of business. The alarm system is hooked up throught the phone line for monitoring that is not in service. We have cable, along with the digital phone which is ran through the cable. Whenever cable goes out, the alarm sounds. Is there a way to disconect the phone line from the alarm system? There is a locked box in one of the closets and I cannot get into it unless I break it, which then I don't know what will happen and not too sure what wire to cut. Cable company and phone co. have no answers. Alarm companies tell me it's not their system, so I am out of luck there. Any electrical techs out there to help me? There is no bypass on the keypad for this function. I tried that already. It has to be disconnected throught the line somewhere.

1. I'm no electrical tech but I had a similar problem. I switched over my phone to the local cable company and the alarm stopped working. They came out to fix it but they had no idea what they were doing and neither did the alarm company. Eventually, I just did iy myself. If your cable phone is like mine, all they did was hook-up a phone modem and tie it into your existing phone lines in the house. The hook-up for the alarm still went through the phone box attached to the outside of my house so the original wires running from my alarm panel to the phone line were still being used. You have at least two options. If you get the box open, you'll probably see what looks like phone lines running into the panel. If you disconnect those, it should break the connection to your cable phone. The other option is to see of you have a phone junction box on the outside or under your house where the original phone lines were connected. If you do, you can disconnect the alarm wires there.
2. Ah, I remember this problem. The most effective way to get the problem solved is to have a company come out and see if they can take care of it or replace the alarm panel. I'm surprised that local companies are looking away from work. You might want to try a few other companies and not the Big ones. If you want to mess around abit and risk frying the panel if you do it wrong - For which I take no responsibility. Basically, if you hook 12 Volts DC to the telephone terminals on the alarm panel MAKE SURE THE PHONE LINE / VOIP IN IS DISCONNECTED. The terminals you are looking for are Tip and Ring or T & R. They are in different locations depending on the panel. As far as popping the can lid, depending on the strength of the can this can usually be done with a screwdriver (Being carefull not to jam it in the panel and ruin the circuit board) or you can also look for a key around the top of the panel or under the lip. I remember from the past you tried contacting me by phone for additional information. I am in Canada and my free tech support to the USA is limited to Email only. I am willing to help but I will not return long distance phone calls, it is by Email only.
