Which of the following is NOT listed as a component of an ESS fire detection system?

• A. Carbon monoxide detectors
• B. Smoke detectors
• C. Heat detectors
• D. Remote monitoring capabilities

Answer: (D)

The main idea is that the fire detection portion of an ESS relies on devices that directly sense fire conditions. Carbon monoxide detectors, smoke detectors, and heat detectors are all sensing elements that respond to different signs of danger: CO detectors respond to toxic gas from incomplete combustion, smoke detectors pick up particles from combustion, and heat detectors react to elevated temperatures or a rapid rise in heat. These devices are the core components that provide the actual detection capability.

Remote monitoring capabilities, while valuable for supervision and rapid response, are not detection devices themselves. They are about how the system communicates alarms to a remote station or building management, rather than about sensing fire conditions. So they aren’t considered a component of the ESS fire detection system.
