To avoid activation during an entry delay, the user must disarm the intrusion system before the countdown hits zero. This is important because the entry delay allows a brief period during which someone can disarm the system after entering the premises. If the disarm process is not completed before the countdown reaches zero, the system will activate, triggering alarms and potentially alerting authorities. This mechanism is typically built into intrusion detection systems to provide a user-friendly way to ensure that legitimate users can enter without inadvertently causing a security breach. The timing of disarmament is crucial for the system to function as intended while balancing security needs and user convenience.
