There are many different kinds of fire alarms: some notifications are local, some remote.
Local, self-contained alarms only notify those who are within earshot of the noise. Anyone hearing an alarm would need to take steps to notify the fire department.
Other "local" alarms could include smoke detectors that are wired together so that when one goes off they all go off, thus signalling anyone within earshot of any of the other smoke detectors.
More sophisticated systems have a local panel and local alarm signal systems that may include horns, strobes, and other signals within the structure.
Finally, some fire alarm panels are required to be connected for "remote signalling" to a licensed monitoring center or dispatcher who can then relay the information to the fire department and others for response to the alarm.
When a fire alarm goes off, it can trigger a call to the emergency services. This feature is only in some models though. In order for this to work, the fire alarm has to be connected to the phone cable, allowing the client to call the fire services.

because it probably has a heat detector in the alarm therefor it goes off.

The purpose of a fire drill is simple and mostly common sense. It is there to help inform you that something is burning, and if there is a fire, the fire alarm it is loud. It saves millions of lives. Say you were sleeping and a fire happened in the kitchen and your bedroom is upstairs, and you didn't know, a fire alarm goes off to alert you so you have time to distinguish it or escape and survive.

An alarm clock will typically beep for about an hour when it goes off. This is if the alarm is not turned off first.
