Which of the following is NOT an optional function of fire warning equipment?

The function of issuing fire safety training is not typically considered a part of the optional functions of fire warning equipment. Fire warning systems are primarily designed to detect and alert occupants of a fire hazard, ensuring that appropriate measures can be taken swiftly to mitigate risks. While monitoring other fire safety systems and notifying the fire department can be seen as additional capabilities that enhance overall fire safety and response, these features are still focused on the immediate concern of fire detection and response.

On the other hand, issuing fire safety training falls outside the scope of what fire warning equipment is designed to do. Fire safety training involves educating individuals on fire prevention, evacuation procedures, and proper responses to fire emergencies, which necessitates a different set of tools and resources. Therefore, it is clear that while beneficial, fire safety training is not an inherent function of fire warning systems.
