What is the function of a receiver in a fire alarm system?

The function of a receiver in a fire alarm system is to process signals from detectors and alert the control panel. The receiver acts as a critical intermediary that receives input from various sensors deployed throughout a building, such as smoke detectors, heat detectors, and manual pull stations. Once a signal is detected, the receiver interprets the information and forwards it to the control panel, which then determines the appropriate response, such as sounding alarms or alerting emergency personnel.

This role is essential for the effective functioning of the fire alarm system, as timely processing of alarm signals ensures that occupants can be alerted and take necessary actions to evacuate safely, and that first responders can be notified promptly, increasing the chances of a successful emergency response.

In contrast, the other functions mentioned in the other options do not accurately define the role of a receiver. For instance, providing power to the alarm circuits relates more to the power supply of the system, not the reception and processing of signals. Connecting the alarm to the local fire department involves external communication features, while maintaining the settings of the alarm system pertains to system programming and configuration rather than the receipt and processing of alarm signals.
