Audible and visual alarms designed to warn of an impending clean agent discharge are called what?

• A. Control Signals
• B. Power Failure Alarms
• C. Pre-Discharge Alarms
• D. Post-Discharge Alarms

Answer: (C)

In clean agent fire suppression systems, audible and visual alarms that warn people before any agent is released are called pre-discharge alarms. Their purpose is to give occupants time to evacuate or take protective actions before the discharge occurs, which is why they’re activated in advance of release. Other types serve different roles: control signals communicate system status or trigger other actions, not specifically occupant warning about an impending discharge; power failure alarms alert when power is lost so backup systems can engage; post-discharge alarms sound after the agent has been released to indicate that the discharge has already occurred. The defining feature of pre-discharge alarms is that they provide warning before the discharge happens.
