Armed State

The CTD system will enter the armed state after the 15 second delay of the arm delay state, unless the BCM detects any door opening within that time. The BCM monitors the inputs (listed above) in order to determine whether to activate the alarm or to disarm the system. The BCM will request the security telltale to remain OFF.
