Not knowing what kind of alarm you are talking about it's hard to say, but if it's a smoke alarm then you should check the batteries, and the wiring. If it's a home security system I would call the person that installed it, and get them to come out and check it.
If the alarm on a 2000 Honda Accord is randomly making noise there may be a problem with the wire harness. When the brain or siren has a short it will randomly make noise and sound off the alarm system in the car.

You may ned to adjust the sensitivity of the motion detector. The wind is probably blowing, or a cat is walking across the car and causing the alarm to activate. my camaro was doing the same thing and i found a bad ground. check and clean all cassis grounds
Thunder, rain, or defective sensor
Unlock passenger side
Suddenly in the last month, my 2001 Merc Sable panic horn goes off randomly. I can of course stop it with the remote panic button, but what is causing this? I can only guess that some other simialar radio signal is activating it. Maybe there is a better answer out there and how do we fix this. It goes off at all times of the night mostly.
to reset the alarm system for a Mercury Sable when the alarm is causing the car not to start, place the key in the ignition. Turn the key only about halfway and leave it in this spot for 10 minutes before trying to start the car.
taking out he fuse disables the whole system..your alarm will no longer work
Maybe there is a fuse that can be removed.
