DSC security system model LED5508 trouble light disable
Hi All
We have a DSC security system. The model looks like LED5508 from the picture.
The system alarm suddenly goes on today. I try to stop it with master key and it does not work.
What I did is key in the master code, not working
press * for 3 sec and heard a long beep, then key in master code. still does not work.
try press # for 3 sec and key in master code, still not working.

LED 5508 is the keypad model, which was used on more than a half dozen specific models. The _system_ model (PC1555, PC5010, etc.) is what will dictate the best course of action to really fix things.
That can be found, normally, on the wiring diagram on the door of the metal enclosure with the system board and the battery. For the _short_ term, unplugging the battery, and the power supply from it's outlet will shut the system down.
Some older models have been known to spontaneously corrupt their programming if allowed to operate on a failing battery in a power failure situation. Your alarm could also be from a smoke detector being triggered (just entering the code won't reset a smoke detector zone).
Basically, right now, we don't have enough information to give you meaningful advice.
