Question 203Safety & Environmental - QMED

The correct answer is D) All of the above. In a typical automatic fire alarm system, any of the listed actions - activating the fire alarm test push button, a rise in temperature triggering a heat detector, or manually activating a fire alarm box - will cause an indication of a fire to be given in the annunciator cabinet. This is because all of these events are designed to signal the presence of a fire emergency to the central fire alarm control panel, which then relays the information to the annunciator cabinet to alert building occupants and emergency responders. The other options are incorrect because they do not represent all the possible ways a fire alarm system can be triggered.
