Question 213Safety & Environmental - QMED70% to pass
The source of power for the CO2 discharge alarm siren is obtained from _______________.
AI Explanation
The correct answer is B) the flow of CO2 under pressure.
The source of power for the CO2 discharge alarm siren is obtained from the flow of CO2 under pressure, which triggers the siren's activation. This is because the CO2 discharge alarm system is designed to be self-powered, relying on the flow of the CO2 gas itself to provide the necessary power to sound the alarm. This ensures the alarm will function even in the event of a loss of primary electrical power.
The other options are incorrect because they do not accurately describe the power source for the CO2 discharge alarm siren. The emergency power and lighting bus (A) and the general alarm 24 volt DC bus (C) are not the direct sources of power for this specific alarm system.
