What is a key fob used for in alarm systems?

A key fob in alarm systems is primarily used to remotely arm or disarm the system. This functionality allows users to easily control their security system without needing to directly interact with the control panel. By pressing a button on the key fob, individuals can activate or deactivate the alarm from a distance, providing convenience and enhancing security, especially in situations where immediate entry or exit is needed.

This ease of use is crucial for maintaining security protocols, as it allows users to ensure their systems are armed when they leave and disarmed upon return, all without requiring physical access to the alarm panel. This feature is particularly beneficial in scenarios where quick actions must be taken, such as entering a building with arms full of items or when entering late at night.

In contrast, while resetting the alarm system, monitoring battery levels, or locking and unlocking doors are also important capabilities in some alarm systems, these functionalities are typically not the primary purpose of a key fob. The key fob's main design focus is to provide a streamlined and efficient way to manage the alarm's armed status.
