A single open or a single ground fault must be automatically annunciated at the FACP within how many seconds on all monitored conductors?

• A. 200
• B. 100
• C. 300
• D. 500

Answer: (A)

The main idea is how quickly a fault on a monitored conductor must be shown at the Fire Alarm Control Panel. For a single open or a single ground fault, the system is required to automatically annunciates this fault within 200 seconds. This interval ensures the fault is quickly brought to attention so maintenance can locate and repair the issue, while avoiding excessive nuisance alarms from transient conditions. A shorter time could cause false alarms, and a longer time could let a real fault go unnoticed. Therefore, 200 seconds is the designated window for this scenario.
