The Alarm system has a switch with which you can control whether the system is unarmed or armed.There are seven more sensor switches in the system. When the system is in Unarmed mode the seven segment LED displays a capital U and when it is Armed it displays a capitalized 'A'. When a sensor or multiple sensor switches are turned on in armed state the display shows the highest value of the sensors triggered. If a sensor is triggered in unarmed state the display will remain as capitalized 'U'.
