FIRE ALARM SYSTEM

What is a Fire Alarm System?

A Fire Alarm system is a group of electronics devices to detect the smoke or heat, carbon-monoxide burning un-knowingly in a building premises, industries or residential houses in case of ignition of fire or an fire emergency. The System is built and integrated with a Control panels called Fire Alarm Control Panel. With the Fire Alarm Control Panel different types of detection, alerting, suppression and warning devices are connected wirelessly or with wirings.

Smoke & Heat Detectors get alert after detection of smoke or heat in its area of coverage in installed areas. A siren or hooter rings the siren after getting the signal from the Fire Alarm Control Panel. A complete fire alarm system integrated with different equipment's can provide  signals to different security and devices. A fire alarm can also activate the hydrant or Fire Sprinkler System. A fire alarm system can open the doors controlled through magnetic locks and access control devices while can send the signals to controllers of electric fans, air-conditions and close them. Fire alarm system can also activate the Fire Suppression system and make voice announcement system in case of fire emergency.

So, Fire Alarm system provide preventive safety and protect the buildings, industries, ware houses, airports, railway stations, theaters or a house from fire disaster.

So, to get protected from un-predictable fire disaster or incident we need reliable technology, brand and Fire Alarm system integrators, importers, and consultants.

What are different Types of Fire Alarm Systems?

1. Conventional Fire Alarm System
Conventional fire alarm system is a system that uses sets of circuits/zones that connect a group of fire detection devices such as smoke detectors, heat detectors and manual call points. The zones or circuits are connected to the control panel. It is less precise as it only indicates zone, not the specific device. The components of conventional fire alarm system are:
i. Control Panel:
It acts as the central hub that controls and manages the entire alarm system. It monitors and coordinates with various components such as smoke detectors, manual call points, and other devices that are connected to the system. It plays a crucial role in fire safety by centralizing monitoring and response functions, ensuring prompt detection of fires, and facilitating efficient evacuation procedures.

ii. Smoke Detectors & Heat Detectors:
These are the devices that helps to detect the fire and smoke and activate or send signal direct to the control panel. These devices include:
a) Smoke Detectors
Smoke detectors are the critical components of fire alarm systems, designed to detect the smoke, indicating a potential fire. Ionization smoke detectors, photoelectric smoke detectors, Dual-Sensor smoke detectors, Aspirating smoke detectors & Beam Smoke Detectors are its types.
b) Heat Detectors
Heat detectors detect rapid increase in temperature, suitable for environments where smoke detectors might not be effective. It is designed to detect significant increase in heat, typically caused by fire, rather than the presence of smoke. Fixed temperature heat detectors, Rate-of-Rise heat detectors & Combination heat detectors are its types.
c) Combination Detectors
Combination detector is the detector that integrates multiple sensing technologies into a single device to enhance the reliability and accuracy of fire detection. It combines smoke detection, heat detection & carbon monoxide detection. Smoke & Heat Combination Detectors, Smoke & Carbon Monoxide Combination Detectors and Triple Sensor Detectors are its types.
iii. Addressable Manual Call Points:
Addressable manual call points are manual activation device used in fire alarm systems that sends a signal to the control panel along with its specific address, allowing the panel to point the exact location when activated. These are commonly used in large buildings, complex, and environments where precise location identification is important for effective emergency response.
iv. Sounders & Visual Alarms:
Sounders are the devices that emit audible signals to alert occupants of a building to evacuate or take action in response to a fire alarm. Sounders are designed to be loud enough to be heard throughout the building, even in noisy environment. Bells, Horns, Voice evacuation systems, etc. are its types.
Visual alarms provide visual signals to alert occupants who may have difficulty hearing or who are in noisy environments. They are typically installed in areas where occupants might not easily hear audible alarms, such as industrial settings, large open spaces, or rooms with heavy machinery.
v. Power Supply
2. Addressable Fire Alarm System
Addressable Fire Alarm System are the system that provides information about the location of a fire by assigning each detector or call point. This system allows for detailed monitoring and control for each device. This system offers several advantages over conventional systems. This system can differentiate between different types of alarms and events. This capability reduces false alarm by providing more accurate information to the operators or authorities. These systems are scalable and can easily accommodated with additional devices or expand to cover larger areas without any changes. These systems can be integrated with other building management systems (BMS), security systems, or emergency communication system, enhancing overall safety.
3. Analog Addressable Fire Alarm System
Analog addressable fire alarm system is a more advanced version of the traditional addressable fire alarm system. They offer continuous monitoring of the environment and devices, providing more detailed information about changes in conditions. They use advanced algorithms to analyze data from detectors, such as smoke density, heat levels, or gas concentrations which allows for more accurate detection of potential fire hazards.
4. Wireless Fire Alarm System
Fire Alarm System that utilizes wireless technology to communicate between detectors, call points, and the control panel, eliminating the need for extensive wiring traditionally associated with fire alarm system installations. They are quick and easy to install compared to wired systems since there is no need to rum cables throughout the building. This reduces installation time and disruption to the building premises. They can be installed in both new and old buildings without the constraints of wiring routes.
5. Conventional Fire Alarm System with Sounders
These systems integrate sounders (alarms) into conventional system, providing audible alerts when smoke or fire is detected. Its Components are:
i. Zoning
ii. Control Panel
iii. Sounders
iv. Manual Call Points
v. Battery Backup
vi. Indicators and Controls
vii. Wiring
viii. Zone identification
6. Intelligent Fire Alarm System
Intelligent fire alarm system is the combination of addressable and analog addressable systems with advanced algorithms to reduce false alarms and improve detection. They are well-suited for complex buildings, high-risk environments, facilities where rapid response and minimal false alarms are critical. These sensors can detect fire conditions at an early stage, enhancing safety and reducing potential fire damage. They monitor environmental conditions and status of detectors.

Maintenance of Fire Alarm System
Maintaining a fire alarm system is crucial to ensure its reliability and effectiveness in detecting and alerting occupants to potential fires. Here are some key aspects of fire alarm system maintenance:
1. Regular inspections
2. Testing
3. Battery Checks
4. Cleaning and Calibration
5. Documentation
6. Fault Detection and Response
7. Upgrades and updates
8. Training
9. Compliance with standards
10. Emergency Response Planning
