3. Processing Signals: The fire alarm control panel processes the incoming signals from the detection devices. It evaluates the severity of the alarm condition based on predefined parameters and programming.

4. Alarm Notification: If the control panel determines that there is a fire or other emergency, it activates audible and visual alarm devices such as sirens, horns, strobes, or speakers installed throughout the building. These alarm devices alert occupants to evacuate the premises immediately.

5. Communication: In larger buildings or facilities, the fire alarm control panel may also be connected to a monitoring service or emergency response center via telephone lines or cellular communication. This allows for quick notification of emergency responders in case of a fire.

6. Control Functions: The control panel may also have additional features and functions, such as controlling suppression systems like sprinklers or gas suppression systems. It can also interface with other building systems such as HVAC (heating, ventilation, and air conditioning) to initiate smoke control or ventilation procedures.

7. System Monitoring: The fire alarm control panel continuously monitors the status of all connected devices and circuits. It performs self-tests to ensure that the system is functioning correctly and alerts building maintenance personnel if any faults or malfunctions are detected.

8. Programming and Configuration: The control panel's programming and configuration can be customized to meet the specific needs and requirements of the building or facility. This includes setting alarm thresholds, defining alarm zones, configuring notification sequences, and integrating with other building systems.
