Pre-discharge alarms verification ensures:

• A. The loudness is adequate.
• B. Adequate warning is provided before agent release to allow evacuation.
• C. The system discharges automatically.
• D. The ventilation system is unmodified.

Answer: (B)

The main concept is ensuring occupants receive a warning before any agent is released. Verifying pre-discharge alarms confirms that the notification sequence activates in time and reaches all affected areas so people have an opportunity to evacuate before the agent is discharged. This timing is essential for life safety because it gives people a chance to move to safe locations and prevents exposure during the release. The test checks not just that an alarm is audible but that the entire warning sequence—audible and visual cues across zones—occurs reliably and promptly. Other aspects, such as automatic discharge or changes to the ventilation, are not the focus of this verification; the emphasis is on providing adequate warning prior to release to allow evacuation.
