Fire alarm and extinguishing system design services

Designing fire alarm and extinguishing systems is one of the essential steps in the field of safety in commercial, residential and industrial buildings. These systems are designed to detect and suppress fires immediately and play an important role in reducing human and financial losses.

Fire alarm system design process

A fire alarm system is designed to detect and notify residents and building safety officials of fires early through audible and visual alarms. These systems are divided into two categories: manual and automatic.

Technical drawings are prepared in accordance with engineering principles and based on current technical standards. During the design stage, detailed hydraulic analyses are performed to ensure appropriate pressure and flow in emergency situations. The location of equipment such as detectors, modules, sirens and control panels is determined by considering the standard coverage radius and environmental conditions to achieve maximum efficiency.

The appropriate system is selected and designed according to the type of space use, environmental hazards and project requirements; Including for warehouses, office buildings, industrial and sensitive centers such as data centers or hospitals. In the design process, the technical specifications of the equipment, piping routes, cabling, functional calculations and ancillary requirements are carefully determined and documented.

Fire extinguishing systems design process

A fire extinguishing system is a set of equipment and processes that are designed and installed to detect, contain and extinguish a fire. Fire extinguishing equipment is specifically used to prevent the spread of fire and protect life and property from fire hazards and plays an important and vital role in ensuring the safety of buildings and facilities.

The fire extinguishing systems design process is a complex and multi-stage process that requires attention to standards, safety regulations, and a detailed analysis of environmental conditions and the type of potential hazards. Here are the main steps in designing fire suppression systems in brief:

1. Hazard Identification and Risk Analysis

Needs Assessment and Hazard Analysis: First, the environment and the type of potential fire hazards must be identified. This includes analyzing ignition sources (such as flammable materials or electrical equipment) and possible fire spread paths.
Fire Type Determination: The type of fire (Class A, B, C, D, and K) that may occur in the environment must be determined. This information will help select the appropriate fire suppression system.

2. Architectural Map Study and Design

Review Building Plans: In this step, engineers must review building and architectural plans to determine where and how fire suppression systems should be installed.
Identify Sensitive Areas: Areas that require special protection, such as server rooms, chemical tanks, or flammable storage areas, must be identified.

3. Choosing the type of fire extinguishing system

Depending on the type of building and its needs, the type of fire extinguishing system should be chosen. Among the common systems:

Sprinkler system: Suitable for most environments and operates automatically in case of fire.

CO2 and FM200 gas systems: Used for water-sensitive spaces such as server rooms or chemical tanks.

Water Mist systems: To protect specific spaces and prevent damage from excessive water during fire extinguishing.

Deluge systems: For high-risk environments such as refineries or hazardous materials warehouses.

4. Hydraulic and gas calculations

Hydraulic calculations: To design a sprinkler system or water spray systems, hydraulic calculations are necessary to measure water pressure and flow. These calculations include determining the volume and pressure of water required in the system, the capacity of water sources and the piping network.
Gas calculations: In gas systems, calculations are made of the amount of gas required to extinguish a fire in a specific space, especially in spaces that are sensitive to water.

5. Selection of required equipment and materials

Selection of valves and nozzles: Nozzles, valves, pipes and related equipment must be carefully selected to provide the best system performance in different conditions.
Equipment installation location: The installation locations of the systems must be carefully determined to provide maximum safety and protection coverage.

6. System installation

Design implementation: At this stage, the installation of fire extinguishing equipment includes piping, installation of sprinklers, installation of smoke and heat detectors and gas systems.
Installation of control panels and valves: These equipment must be installed in specific locations to provide easy access to them for system control.

7. Testing and Commissioning

System Performance Testing: After installation, all fire extinguishing systems should be tested to ensure they are functioning properly. These tests include water pressure testing, sprinkler coverage checks, and gas system performance tests.
Alarm Equipment Testing: Smoke and heat alarm systems should also be tested to ensure that they will activate properly in the event of a fire.

8. Ongoing Training and Evaluation

Employee Training: After the system is installed, it is essential to train employees on how to use and monitor fire extinguishing systems.
Periodic Inspection and Maintenance: After installation, the system should be regularly inspected and maintained to ensure that it is always in working order.

9. Compliance with Standards and Regulations

The design and installation of fire extinguishing systems should be carried out in accordance with national and international standards (e.g. NFPA, EN, ISO) and local safety regulations. These regulations are designed to increase the efficiency of systems and ensure complete safety of the building and people against fire.

Get advice on designing a fire alarm and extinguishing system

An effective fire alarm and suppression system requires the cooperation of various specialists, including mechanical, electrical, safety and architectural engineers, who must all carefully carry out the design and installation steps to ensure that the system is fully fire safe.

The design process of fire alarm and suppression systems at Rama Asli Company begins with a detailed analysis of the architectural, infrastructural and operational conditions of the project. The engineering team, with a specialized approach and based on risk assessment, develops a design strategy to provide a design that meets the specific needs of each project. All designs are based on international standards such as NFPA as well as local requirements, including the regulations of the Tehran and Kashan Fire Departments. This approach, while ensuring technical quality, helps facilitate obtaining legal approvals.
