Visonic GSM Net Fail trouble , but GSM not connected. How do I clear this?

Just guessing but the problem when you opened the case to change the battery. That tripped the tamper alarm. On my system it is part of the BIOS and I need to go in to the BIOS to reset it and or turn it off. These links may help:

0176 Security The system has been tampered with

Usually the green and red, but best way to find out is pop the phone port box where you land line comes into the house, and check to see what wires are used. Some countries use 2 wire systems others use 4

Line failure is related to power not phone line. What is the exact model number?

you can look up site like buy chargers then put your model number in then you will be good to go.

how can i reset poxermax system if i forget master installer code ?

Hi, No, you just change your number in the user settings page.

Press next on the front twice to 'user settings' put your code in.. then you are on the phone number setting as the menu begins, press OK and change it with the numeric pad. enjoy

Hi, first of all, are you sure its on the same frequency as your main module, 800 or 400? before I help further?

took the face off and removed battery pushed the tamper button's on sensor device one on front the other on back and replaced battery. worked perfect.

I purchased an AT&T Go Phone to use it's sim card in my gsm module. It did not work. I called AT&T and they told me the gsm module is not supported. 
I then purchased a T-Mobile prepaid phone and installed it's sim card in the gsm module and it works perfect every time.
