Fire Alarm and Firefighting System Design
The principled and standard design of fire alarm and extinguishing systems is one of the most important steps in ensuring the safety of people’s lives and protecting capital in a variety of industrial, commercial, administrative and residential projects. A professional and engineered system can identify fire hazards in the shortest possible time and, with a quick and effective response, prevent the spread of fire and irreparable damage. Therefore, using specialized fire alarm and extinguishing system design services plays a key role in ensuring the sustainable safety of buildings.
Fire alarm and extinguishing system design services are carried out based on technical studies, detailed risk analysis, understanding the type of space use and assessing environmental conditions. In this process, the correct selection of equipment, including detectors, fire alarm panels, sprinklers, water, gas or powder extinguishing systems and their principled placement, is carried out based on the requirements of reputable international standards such as NFPA, EN and FM. Standard design, in addition to increasing the level of safety, will optimize costs and increase the life of the equipment.
A comprehensive and accurate design, in line with the requirements of the Fire Department and National Building Regulations, will also facilitate the possibility of obtaining legal approvals for the project. Also, complete coordination of fire alarm and extinguishing systems with other mechanical and electrical installations of the building prevents the occurrence of operational interference and operational problems in the future.
The purpose of providing fire alarm and extinguishing systems design services is to create reliable, intelligent solutions that are tailored to the needs of each project; Solutions that, while adhering to engineering principles and current world standards, guarantee peace of mind for the employer and maximum security for users.
Fire alarm system design steps
- Project Review and Evaluation: In the first stage, the type of building use, area, number of floors, fire risk, and legal requirements and standards are reviewed to accurately determine the level of protection required.
- Selecting the type of fire alarm system: Based on the project conditions, a conventional or addressable fire alarm system is selected to best meet both technical efficiency and safety requirements.
- Equipment Identification and Location: Accurate location of detectors (smoke, heat, flame), fire alarm buttons, sirens, and flashers is carried out in accordance with the NFPA 72 standard and executive instructions.
- Design of drawings and cabling routes: Technical drawings including cabling routes, loops, zoning, location of central panel, and peripheral equipment are designed accurately and effectively.
- Selection of standard equipment: All equipment used is from reputable brands and has standard approvals and is in accordance with the project needs and safety requirements.
- Design of performance scenario and communication with other systems: The way the system operates in the event of a fire, sending commands to peripheral equipment such as elevators, smoke exhaust fans, fire extinguishing system and BMS is designed and coordinated.
- Preparation of final documents and drawings: Finally, final drawings, calculation booklet and technical documentation are prepared for implementation, fire approval and operation.
Firefighting system design steps
- Fire risk assessment and evaluation: First, the type of building use (residential, commercial, industrial), area, number of floors, type of flammable materials, and fire risk level are examined. This analysis is the main basis for selecting the type of fire extinguishing system.
- Selecting the type of fire extinguishing system: Based on the risk assessment, the appropriate system is selected; Including water systems (sprinklers, hydrants and fireboxes), gas (FM200), foam or powder, each of which has its own specific application.
- Compliance with legal standards and regulations: The system design is based on valid standards such as NFPA (NFPA 13, NFPA 14, NFPA 20), National Building Code and Fire Department guidelines to ensure safety and necessary approvals.
- Hydraulic calculations of the system: At this stage, the required flow and pressure, pipe size, pressure drop, static height and fire pump capacity are calculated to ensure the correct operation of the system in case of fire.
- Fire extinguishing equipment placement: Accurate placement of equipment including sprinklers, fire boxes, hydrants, water storage tanks, fire pumps and control valves in accordance with Technical and standard drawings are prepared.
- Design of drawings and implementation details: Implementation drawings including plans, riser diagrams, piping routes, equipment locations and installation details are prepared to ensure error-free system implementation.
- Coordination with fire alarm system: The fire extinguishing system is coordinated with the fire alarm system, BMS, elevators and ventilation systems so that in the event of a fire, functions are performed automatically and seamlessly.
- Preparation of documentation, testing and project delivery: Finally, technical documentation, calculation booklet and final drawings are prepared and after the system is implemented, testing and commissioning are carried out in accordance with NFPA standards.
