Arm the alarm by opening the plastic keypad cover (if one is present) and keying in your alarm code.
Press "Arm" or the pound "#" key and wait for the armed status. View the small screen on the keypad or wait for the "armed" indicator light to come on. A beep also may sound to indicate the system is armed.
Leave the building and lock the door within 30 seconds, the alarm may beep during this time and say "Arming" on the screen.
Disarm the alarm promptly when you return. Access the keypad and enter your code followed by the "Disarm" or "#" key. Wait for the beeping to stop. If it does not stop, try reentering your code and pressing Disarm or "#." The beeping will stop once the proper code is entered.
Press the "Emergency" keys, such as "Police" or "Fire," if your system includes direct access to these services in the event of an emergency.
Use the "Setup" or "Menu" key to enter the on screen menu, if available, and follow on screen prompts for changing the code or display time, or setting up "auto" arming for certain times, if applicable.
