How does Fire Alarm System work?


Fire can be devastating, causing damage to property and endangering lives. That’s why it’s essential to have a fire alarm system installed in buildings to detect and alert occupants in the event of a fire. Fire alarm systems can provide early warning, allowing occupants to evacuate safely and quickly. But have you ever wondered how their systems work? In this blog, we’ll explore the components of a fire alarm system, how they work together, and the types of fire alarm systems available. We’ll also discuss the importance of regular testing and maintenance to ensure the system is functioning correctly when it’s needed most. So, whether you’re a building owner-manager, or just curious about fire alarm systems, keep reading to learn more.


Components of fire alarm systems


1. Smoke detectors: Smoke detectors are the most common type of detector used in fire alarm systems. They detect smoke particles in the air and trigger the alarm when a certain level of smoke is detected.


2. Heat detectors: Heat detectors are used in areas where smoke detectors are not appropriate, such as kitchens and trigger the alarm when a certain temperature threshold is reached.


3. Manual call points: Manual Call points, also known as break glass units, are devices that allow occupants to manually trigger the fire alarm system in the event of a fire.


4. Control panel: The Control panel is the brains of the fire alarm system. It receives signals from the smoke detectors, heat detectors, and manual call points and triggers the alarm.


5. Notification devices: Notification devices, such as sirens, horns, and strobe lights, are used to alert occupants to the danger of a fire.


6. Monitoring system: The monitoring system allows the fire departments to be notified in the event of a fire, enabling them to respond quickly and efficiently.



How it works?


· Detection of smoke or heat by detectors:

One of the primary functions of a fire alarm system is to detect the presence of smoke or heat caused by a fire. Smoke detectors are the most common type of detector used in fire alarm systems and work by detecting the smoke particles in the air. Smoke detectors can be either ionization or photoelectric, and some are a combination of both. Ionization smoke detectors are sensitive to small particles, while photoelectric detectors are more sensitive to larger smoke particles.

Heat detectors, on the other hand, detect changes in temperature and trigger the alarm when a certain temperature threshold is reached. Heat detectors are often used in areas where smoke detectors are not suitable, such as kitchens, where cooking smoke or steam could trigger false alarms.

When smoke or heat is detected by the detectors, a signal is sent to the control panel, which triggers the alarm. This early detection of a fire can be critical in allowing occupants to evacuate quickly and safely before the fire spreads.



· Triggering of alarm by the control panel:

Once smoke or heat is detected by the detectors in a fire alarm system, the signal is sent to the control panel. The control panel is the central processing unit of the system and is responsible for receiving and processing signals from the detectors, manual call points, and other components of the system.

When a signal is received from the detectors, the control panel triggers the alarm. This may include sounding sirens or horns, flashing strobe lights, or a combination of both. In some cases, the control panel may also activate sprinkler systems or other fire suppression systems.

The control panel may also have the capability to communicate with a monitoring service or the fire department. This allows for quick response times and may help to prevent the fire from spreading and causing further damage.

It's important to note that the triggering of the alarm by the control panel is an automatic process and does not require any manual intervention. This allows for a quick response time and can be critical in saving lives and minimizing property damage.



· Notification devices alert occupants:

Notification devices are a critical component of any fire alarm system. Once the alarm is triggered by the control panel, the notification devices are activated to alert occupants of the building to the danger of the fire.

Notification devices may include sirens, horns, or bells that sound loudly throughout the building. In addition, strobe lights may also be used to provide a visual alert to individuals with hearing impairments.

Notification devices are strategically placed throughout the building to ensure that they are audible and visible from any location. This helps to ensure that all occupants are alerted to the danger of the fire and can safely evacuate the building.

In some cases, voice alarms may also be used. These alarms use pre-recorded or live voice messages to provide specific information about the location and severity of the fire, as well as instructions on what to do and where to go for safe evacuation.


· Monitoring by fire department:

Monitoring by the fire department is an important feature of many modern fire alarm systems. When a fire alarm system is monitored, it means that the system is connected to a central monitoring station that is staffed 24/7. In the event of a fire, the system automatically sends a signal to the monitoring station, alerting them to the presence of a fire.

Once the monitoring station receives the signal, they immediately notify the fire department, which then responds to the fire. This quick response time can be critical in saving lives and minimizing property damage.

In addition to notifying the fire department, monitored fire alarm systems may also be connected to other emergency services, such as medical responders or the police, depending on the type of building and the local regulations.

It's important to note that not all fire alarm systems are monitored, and it's not always required by law. However, for larger buildings or buildings with a high risk of fire, monitoring can provide an added level of safety and peace of mind.
