Fire alarm control panel – the system hub monitors inputs and system integrity, controls outputs and relays information.
Primary power supply – primary power for your fire alarm system is usually supplied in the form of 124V or 240V AC from the power company.
Secondary (backup) power supply – backup power supplies usually consist of lead-acid batteries used to power the system in case the primary power source fails.
Initiating devices – these are your activation stations, and can be manual (pull stations) or automatic (smoke detectors).
Notification appliances – notification appliances are things like flashing lights, strobe lights, horns, speakers, etc. that actually let people know of the danger in your building.
Building safety interfaces – these are things like exit lighting, ventilation systems, etc. that make it easier for people to get out of the building once a fire has started.

A commercial fire alarm system consists of four basic parts: a fire alarm control panel, initiating devices, notification devices, and a primary and backup power supply. The fire alarm control panel is the brains of the operation, and when an initiating device is triggered, it sends a signal to the fire alarm control panel and triggers the notification devices or the alarm. [1] Notification devices include flashing lights, horns, and chimes, which alert people in the building of the fire. [2,3] All of these components must be connected and working together for the fire alarm system to be effective. [1] References: [1] What Components Complete a Fire Alarm System?

The four basic parts of a fire alarm system are:
Smoke Detector or Heat Detector: This is the device that detects the presence of smoke or heat in the environment and triggers the alarm.
Control Panel: This is the central component of the fire alarm system that receives signals from the detectors and sounds the alarm. It also provides information on the location of the fire to the monitoring service.
Notification Devices: These are the devices that produce an audible and/or visual signal when the alarm is triggered. They can include sirens, horns, strobe lights, and voice evacuation systems.
Power Supply: This is the source of power for the fire alarm system. It can be either battery-powered or connected to the building's electrical system with a backup battery in case of power outages

The four basic parts of a fire alarm system are a control panel, smoke detectors, heat detectors, and manual pull stations. The control panel is the central unit that receives signals from the detectors and activates the alarm. Smoke detectors detect the presence of smoke and alert the control panel. Heat detectors detect changes in temperature and alert the control panel. Manual pull stations are typically located near exits and allow people to manually activate the alarm in case of an emergency.
The four basic parts of a fire alarm system are:
1. Control Panel: The control panel is the main component of the fire alarm system. It receives information from different sensors and detectors, processes the information, and triggers the appropriate response, such as activating alarms, notifying authorities, and initiating fire suppression systems.
2. Detectors: Fire detectors are designed to sense signs of a fire or smoke. There are various types of detectors, including heat detectors, smoke detectors, flame detectors, and gas detectors. They are strategically placed throughout the building to quickly identify any indications of a fire.
3. Notification Devices: Notification devices are responsible for alerting occupants of a building about a fire. These devices include fire alarms, horns, strobe lights, sirens, and speaker systems. They are strategically placed to ensure that the warning is audible and visible from various locations within the building.
4. Power Supply: A reliable power supply is crucial for the proper functioning of a fire alarm system. This includes primary power supply from the building's electrical system and a backup power supply, usually in the form of batteries or generators, to ensure continued operation in case of power outages.

A basic fire alarm system consists of four essential components that work together to detect and alert individuals to the presence of a fire or smoke. These four fundamental parts of a fire alarm system are:
1. Initiating Device: Initiating devices are sensors or detectors that sense the presence of smoke, heat, or fire. Common types include:
a. Smoke Detectors: These devices respond to the presence of smoke particles in the air and are typically found in homes and commercial buildings.
b. Heat Detectors: Heat detectors are triggered when they sense a rapid increase in temperature, such as that caused by a fire. They are commonly used in environments where smoke detectors may produce false alarms, such as kitchens.
c. Flame Detectors: Flame detectors respond to the presence of flames by detecting the infrared, ultraviolet, or visible light emitted by the fire.
d. Manual Pull Stations: These are manual alarm initiation devices that can be activated by individuals in case of an emergency. They are typically found near exits and are used to manually trigger the fire alarm.
2. Control Panel: The control panel, also known as the fire alarm control unit (FACU) or fire alarm panel, is the central hub of the fire alarm system. It receives signals from the initiating devices and, based on the information received, triggers the alarm notification appliances (such as sirens, horns, and strobes), initiates communication with a monitoring center, and may also control the release of fire suppression systems like sprinklers.
3. Notification Appliances: Notification appliances are devices that alert occupants to the presence of a fire or smoke. These devices can include:
a. Audible Devices: These produce loud, attention-grabbing sounds, such as sirens, horns, or bells.
b. Visual Devices: Visual appliances include flashing strobe lights or emergency lighting, especially important for alerting hearing-impaired individuals.
c. Voice Alarms: In some systems, voice alarms or public address systems may be used to provide specific instructions or information to building occupants during an emergency.
4. Power Supply: A reliable power supply is essential for the proper functioning of a fire alarm system. Fire alarm systems are typically powered by both primary and backup power sources to ensure continuous operation, even during power outages. Backup power sources may include batteries or generators.
These four components work together to detect fires, communicate alarms to building occupants, and, in some cases, notify monitoring centers or emergency services. Fire alarm systems can vary in complexity and additional features, but the basic four-part configuration is the foundation of any fire alarm system.
