Enter the building protected by the alarm system.
Press the keys on the alarm system keypad that correspond to the numbers in the alarm system's "authorized entry" code, in the order in which those numbers appear in the authorized entry code. If the "authorized entry" code is 1, 3, 2, 4, then press 1, followed by 3, then 2 then 4. After entering the code, press the "Enter" key on the alarm system keypad, if the key pad is equipped with an "Enter" key.
Unplug the power transformer--a black or gray box adjacent to the main alarm unit that provides the primary power source in the event that the system malfunctions. Remove the nut from one post of the back-up battery and lift one of the power leads from that post. This fully disables the alarm.
