In high-rise commercial buildings, fire detection and alarm systems are critical for the safety of life and property. In these buildings, it is recommended to use more advanced and precisely addressed fire detection systems instead of traditional zone-controlled fire detection systems.

What is Addressable Fire Detection System?

Addressable fire detection system is a system in which each detector and alarm device is connected to the system with a separate address. In this way, the exact location where the fire occurred can be determined instantly. This allows fire and emergency crews to respond more quickly and accurately.

Advantages of Addressable Fire Detection System in High-Rise Commercial Buildings:

Faster and more accurate detection: The exact location of the fire can be determined instantly.

More effective response: Fire and emergency crews can respond more quickly and accurately.

Less evacuation: People close to the fire zone are evacuated, while those on other floors can stay put.

Less damage: Fire can be detected and extinguished at an early stage.

Less panic: Knowing the exact location of the fire reduces the feeling of panic.

Addressable Fire Detection System Design:

When designing an addressable fire detection system, many factors such as the size of the building, number of floors, purpose of use and risk level should be taken into consideration. The system must be designed in accordance with international standards such as NFPA 72 and local regulations.

Points to Consider in System Design:

Type and placement of detectors

Type and placement of alarm devices

Cabling and connectors

Control panel and software

Power supply and backup

Maintenance and testing plan

Detector Types:

Smoke Detectors: The most commonly used type of detector. There are two types: optical and ionized.

Heat Detectors: Triggered when it reaches a certain temperature.

Combined Detectors: Sensitive to both smoke and heat.

Gas Detectors: Detects flammable gases.

Flame Detectors: Detects infrared light emitted by flames.

Detector Placement:

Detectors should be distributed equally across all floors and sections of the building.

Detectors can be mounted in the center of the ceiling or on walls.

Detectors should be placed at least 30 cm away from obstacles such as beams, columns and ventilation ducts.

Alarm Devices:

Bells: The most commonly used alarm device for fire alarm.

Sirens: Produce louder and more noticeable alarm sounds.

Strobe Lights: Used for visually impaired people.

Loudspeakers: Used for fire-related announcements and instructions.

Cabling and Connectors:

Cables must be fire resistant and insulated.

Fasteners must be strong and reliable.

Control Panel and Software:

The control panel is the control center of the entire system.

The software processes and displays information from detectors and alarm devices.

Kontrol paneli, arızalar ve diğer olaylar hakkında kullanıcıları uyarmalıdır.

Power Supply and Backup:

The system must be connected to an uninterruptible power supply (UPS).

If the UPS fails, the system must be powered by a generator.

Maintenance and Testing Plan:

The system should be regularly maintained and tested.

Maintenance and testing must be performed by qualified personnel.

Technical details:

The detection sensitivity and sensitivity of the detectors can be adjusted.

The volume and duration of alarm devices can be adjusted.

The control panel can be used to record and report events.

Conclusion:

Addressable fire detection systems are one of the most important elements of fire safety in high-rise commercial buildings. A properly designed and implemented addressable fire detection system contributes significantly to the protection of life and property safety.
