alarm malfunction

[Norm]

alarm on my 95 continental goes off for no reason,all day it seems fine but as soon as it sets around for a few hours ,as soon as it gets dark out side the horn sounds, a continuous blaring sound. Anyone with the same problem?

check your battery, my 97 used to do that and it's because we needed a new battery in it, never did it again
