It can be reset using the pin combinations that we know already or can use the reset button and then the PIN to reset. We can do a power run by removing the battery from the alarm and then insert the battery again so that it will ask for the PIN again and we can start using it again

To my knowledge and best guess, you would hold down the test and peak level buttons until the system beeps or flashes (depending on the system). If this fails, it is probably not the best solution, but you could remove the system batteries (if it is not hard wired).
