Section 2: Arming and Disarming Your System
Getting Ready to Arm Your System
This section describes how to perform the basic functions of your system: arming and dis- arming. Read this section carefully.
Before you arm your system, make sure that the system is Ready. You can tell that the sys- tem is ready when the Ready light is ON. If this is the case, you can arm your system - use one of the arming methods described on pages
If the Ready light is ON and the LCD5500Z keypad displays “Secure System or Enter Code”, you can arm your system. However, some zones on the system are still open. Before arming, confirm that no zones are left open unintentionally.
If your system is not ready, do the following:
On an LCD5500Z keypad:
1.If the Ready light is OFF, or if the keypad displays “Secure System Before Arming”:
•Close all doors and windows
•Stop motion in all zones with motion detectors
2.If LCD5500Z keypads show “<>”, use the 
keys to scroll through system mes- sages and check that the system is clear of troubles and that no zones are bypassed unintentionally. See “Identifying Trouble Conditions” on page 17 and/or“Bypassing Zones” on page 15.
On a PC55XXZ or LCD5501Z keypad:
1.If the Ready light is OFF, the system is not ready to be armed:
•Close all doors and windows
•Stop motion in all zones with motion detectors
2.If the Trouble light is ON, view and correct any existing troubles. See “Identifying Trouble Conditions” on page 17.
3.If the Bypass indicator is ON, check that no zones are bypassed unintentionally. See “Bypassing Zones” on page 15.
