Mine doesn't go off immediately, I am guessing/hoping maybe its a spider or something. Is that possible?

Sometimes it would take a while before the alarm would go off, usually in the early hours
The siren module internal battery has a life of 8 to 10 years, when it expires it gives the symptoms described. As per that link I posted I replaced the siren module about 18 months ago & it's been fine since.
