Final answer:
Electronic monitoring of a fire system involves the use of technology to continuously detect and monitor fire-related events. It includes the installation of sensors and detectors that are connected to a central monitoring system, which can alert authorities or initiate appropriate actions. An example of electronic monitoring is the use of ionization-type smoke detectors.
Step-by-step explanation:
Electronic monitoring of a fire system refers to the use of technology to continuously monitor and detect fire-related events in a building or area. It typically involves the installation of sensors, detectors, and interconnected devices that can detect various aspects of a fire, such as smoke, heat, or flames. These devices are connected to a central monitoring system, which can automatically alert the authorities or initiate appropriate actions, such as activating sprinkler systems or notifying occupants.
An example of electronic monitoring in a fire system is the use of ionization-type smoke detectors. These detectors contain a small amount of Americium-241, which emits alpha particles that ionize the air in the ionizing chamber of the detector. When smoke enters the chamber, it impedes the movement of ions and reduces the conductivity of the air, causing a drop in the electric current. This change in current triggers an alarm, alerting occupants to the presence of smoke and a potential fire.
