I'm not sure what kind of answer you're expecting. You've given nonindication at all of the make and model of the alarm or the control panel (if separate). So really there's nothing anyone can offer at this stage.
For speed, you might be able to get some info from the manual (installation and / or users manual), which could be available with a simple search.
Post again with the make and model and we'll see if anyone drops by with some help.
