What is the function of a keypad in an alarm system?

The function of a keypad in an alarm system is primarily to arm, disarm, and program the alarm system. Keypads serve as the main interface through which users interact with security systems. They allow users to enter a code to activate or deactivate the alarm, ensuring that only authorized individuals can control the system. Additionally, many keypads include functions for configuring settings such as notification preferences, zones, and other advanced features.

While other elements in a security system may provide power, display status, or connect devices, these functions do not directly relate to the primary purpose of a keypad. The ability to control the operational status of the alarm system through a keypad is fundamental in allowing users to manage their security effectively.
