What functionality does a delay feature provide in an alarm system?

The delay feature in an alarm system provides a set period for the user to disarm the system after it is triggered. This is particularly useful when users need time to enter or exit a premises without accidentally setting off the alarm. For instance, when a user activates the alarm at night, they may need a moment to enter the home and disarm the system before the alarm triggers. The delay allows for this grace period, reducing false alarms and ensuring that legitimate users can operate the system comfortably.

The delay feature is essential for the practical use of alarm systems in residential or business settings, as it balances security with user accessibility. Other functionalities like immediately triggering the alarm or logging entries do not provide the necessary user-friendly aspect that the delay feature introduces.
