Certified Information Systems Auditor (CISA) — Question 454

Which of the following fire suppression systems needs to be combined with an automatic switch to shut down the electricity supply in the event of activation?

Answer options

• A. FM-200
• B. Dry pipe
• C. Carbon dioxide
• D. Halon

Correct answer: B

Explanation

The Dry pipe system must be integrated with an automatic switch to turn off electricity when it activates, as it can introduce water into areas that may have electrical hazards. The other systems, like FM-200, Carbon dioxide, and Halon, do not require this type of electrical shutdown because they do not use water and thus do not pose the same risk of electrical hazards.
