All/Perimeter System Arming

Area Assignment: Your security system is divided into two separate areas. Motion detectors, inside doors, and other interior protection devices are assigned to the Interior area while windows and exterior doors are assigned to the Perimeter area.

Perimeter or All: When arming an All/Perimeter system, the keypad displays PERIM ALL. If you select ALL, you arm both the Perimeter and the Interior of the system. You will want to arm both of these areas when leaving with nobody left inside. Selecting PERIM arms only the Perimeter of the system. Perimeter arming is for when you are staying inside but want the comfort of knowing the exterior doors and windows are armed. Perimeter arming allows you to move freely about inside without setting off any interior alarms.

System Ready/System Not Ready Keypad Displays

When all zones in the system are in a normal condition, the keypad displays SYSTEM READY. If there are one or more zones that are not in a normal condition, the keypad displays SYSTEM NOT READY. Pressing any top row Select key during this display shows the zone name allowing you to investigate the problem.
