Question 3743 Deck General

The correct answer is D) an audible alarm and time delay. The reasoning for this is that fixed CO2 systems with a capacity over 300 lbs (136 kg) protecting spaces other than tanks are required to have an audible alarm and a time delay before automatic release. This allows personnel to evacuate the protected space before the CO2 is released, preventing injury. The other options are incorrect because: A) is missing the time delay requirement, B) is not a requirement for this size system, and C) automatic release without an alarm and time delay would be unsafe.
