How does the Exit Alarm feature work if I accidentally leave a door open when arming?

If an entry/exit door or interior zone is faulted before the exit delay expires and remains open, the system sounds an alarm and starts the entry delay timer. If you disarm before the entry delay ends, the alarm stops and 'ALARM CANCELED' is displayed with no message sent to the Central Monitoring Station. If you do not disarm in time and the zone remains open, the alarm continues and an 'EXIT ALARM' message is sent to the Central Monitoring Station after the installer-programmed dial delay expires.
