you have to check the charge of the battery that dials 12 vdc, connect only the alternating current and check with your multimeter the red and black wires that go to the battery that sends a charge of 13 vdc, check your auxiliary output should mark you 13 vdc, If you have less than 6 VDC, you have a short, remember that some systems can be configured so that the faults are not reflected, check the configuration, if you do not find it, reset your alarm in both hardware and software, test your battery with another alarm,
Dear, I did the indicated thing and now everything is going well. Apparently the negative terminal had not been properly connected and the battery had not been charged.
Thank you. I could not choose it as a solution because it was a comment. If you put it on as a solution, I will rate it.
