Ater the power blackout, I wanted to install a backup battery that maintains
the power of the alarm system for a week. Do you have any suggestions?
Thanks

Yes.
Get an APC (American Power Corp.) 500 or 700 or 1000 Va.
And plug in your transformer.
What is your Ma draw and how much time do you need.

But your monitoring station will not get a AC failure. Your external battery
will last four days, then go to the internal battery, give the station a AC
failure, Run on the internal battery and will die and quite.

Go down to the neighborhood auto supply and buy a good car battery, a
battery charger, and a marine battery box.

Hook the charger to the battery and put it on trickle or maintain or
whatever
the right setting is for your charger. Use a diode to block the charging
voltage
coming from the alarm panel and let the battery charger maintain your large
battery.
