You've probably once seen or heard a fire alarm system giving out an incessant notification sound and wondered how it works.

Thus, in this article we will explore the important things you should know about the accessories that form the Component parts of a fire alarm system.
As previously stated, the fire alarm panel constantly monitors and indicates the status of the system. Normal, Alarm, and Trouble are the three states of operation for most systems.
The system is in a Normal State when all devices, appliances, wiring, and circuits are working properly and no alarms are triggered.
The system enters an Alarm State when an initiating device is engaged. The signaling appliances will sound, alerting building residents to the danger.
Also, the alphanumeric display on the control panel will show which zone of the building(s) the alarm is coming from, allowing emergency workers to come swiftly to the correct location.
The system enters Trouble State and is displayed on the control panel if a short or open wire develops in the circuits linking the fire alarm panel and initiating devices, or within the panel's wiring or zone cards, or if the system's phone line connection is not operating.
A buzzer will sound to alert maintenance people to the problem, and the panel will identify which zone the issue is in.
The buzzer is loud enough to be heard, but it isn't as loud as the indicating appliances, so it won't be mistaken for a true alarm.
The system's starting devices are connected to the fire alarm panel through 2- or 4-wire circuits.
This circuitry enables the control panel to track the status of its initiating devices, usually by zones, and determine whether they are in normal or alarm mode. These readings are displayed on the control panel's display panel.
