Hey, so this is my problem. I am a new buyer of a house with an installed alarm system. Unfortunately, the past owner didn't give me the password they were using so I decided to reset the system to default setup. I located the XL-2 board, disconnected power, shorted necessary points on the board as per the manual, connected power and removed shorts few seconds later. Then, when I came back to XL4600sm numberpad, the alarm and horn went off. STAY light is solid red, ARM is blinking red and READY is blinking green. I tried turning the alarm off with the default code (presumably 1234) with no success. I have repeated this process few times thinking I did the default reset incorrectly but with the same results. I would appreciate any advice or help regarding this as my alarm system is completely useless right now as I had to disconnect the horn with the keypad still blinking red.
