Which of the following is NOT an abnormal environmental condition that can be monitored by a security system?

• A. Carbon monoxide
• B. Moisture
• C. Temperature
• D. None of the above

Answer: (D)

The idea being tested is that security systems can monitor common environmental hazards by sensing abnormal conditions. Carbon monoxide detectors watch for dangerous gas levels that can harm occupants; moisture sensors detect leaks or water intrusion to prevent damage and mold; temperature sensors track unusual heat or cold that can signal HVAC failure or equipment problems. Because each of these conditions represents an abnormal environmental situation that a security or monitoring system is designed to detect, there isn’t an item in the list that isn’t monitorable. So the correct choice is None of the above.
