Fire Sprinklers

What They Are, How They Work, and How to Ensure Proper Installation

Fires are among the greatest risks to safety in residential, commercial, and industrial buildings. Implementing proper fire protection systems is not only a responsibility but also a necessity to safeguard human lives and material assets. Fire sprinklers stand out as an efficient technical solution, as they detect and control fires in their early stages, minimizing damage.

At ME-GA Proyectos de Sonora, we have the expertise to design and integrate fire protection systems for all types of projects. Our approach ensures that each sprinkler system is installed in compliance with current regulations, maximizing its effectiveness in critical situations.

Fire Protection System Design

Designing fire protection systems involves considering various factors, such as the type of construction, materials used, and specific risks associated with the environment. Proper planning and distribution of sprinklers are essential to optimize coverage and response speed during emergencies.

Let's Talk

What Are Fire Sprinklers?

ire sprinklers, also known as sprinklers, are devices designed to detect and control fires in their early stages. They function as part of a fire protection system consisting of a network of pipes and valves that efficiently distribute water or fire-extinguishing agents. Their primary purpose is to mitigate fire damage, protecting both structures and human lives.

These systems operate autonomously, activating only when the ambient temperature reaches a predetermined threshold. This makes them an ideal solution for responding quickly and locally to a fire, without causing unnecessary damage to other areas of the building.

Key Features According to the NMX-S066-SCFI-2015 Standard

According to the NMX-S066-SCFI-2015 standard, fire sprinklers must meet specific parameters to ensure their effectiveness:

Thermal Sensitivity: This is the sprinkler's ability to respond quickly to heat, measured by the Response Time Index (RTI).
Response Time: Rapid-response sprinklers have an RTI of less than 50 meters-seconds, while standard-response sprinklers have an RTI greater than 80 meters-seconds.

These standards ensure that sprinklers can control or extinguish fires in their early stages, preventing further spread.

How Do Fire Sprinklers Work?

Activation Process of Fire Sprinklers

Fire sprinklers operate autonomously to detect and respond to a fire in its early stages. The activation process begins when the sprinkler detects heat, smoke, or both, depending on the installed system. Once activated, water stored in the pipes flows toward the sprinkler nozzles, releasing in a targeted manner to extinguish the fire or limit its spread.

The design of hydraulic networks ensures that the pipes distribute water uniformly and efficiently, optimizing the performance of the fire sprinkler system.

Main Components of Fire Sprinklers

The sprinkler system consists of:

Pipes: Distribute water from a pressurized source to the sprinklers.
Valves: Control the flow of water within the system.
Nozzles or Sprinklers: Evenly disperse water over the area affected by the fire.

These components work in coordination to provide an effective response to any incident.

Activation Methods

By Temperature:
This method uses a heat-sensitive bulb or a fusible link that activates when a predefined temperature is reached. Once activated, water flows to the affected area.
Through Fire Detectors:
In this case, the system is connected to smoke or heat detectors. Upon identifying a fire, these devices send a signal to open a control valve, allowing water to be released.

Types of Fire Sprinklers

Pre-Action Sprinklers

Pre-action sprinklers are ideal for minimizing water damage, as the system remains dry until a fire is detected through a smoke or heat detector. This type of sprinkler system is unique because it requires two activation signals: one to fill the pipes with water and another to release the flow to the nozzles. It is particularly useful in sensitive areas.

Applications:

Data centers and server rooms
Libraries and historical archives
Facilities with gas systems where water damage must be limited

Wet Sprinklers

Wet sprinklers are the most common and quickest to respond. The pipes are constantly filled with water, allowing the system to activate immediately when a sprinkler detects a fire.

Applications:

High-rise office buildings
Residential buildings
Hospitals and shopping centers

Dry Sprinklers

Dry sprinklers are designed to prevent freezing issues in cold climates. Instead of water, the pipes are filled with pressurized air, which is released when the system is activated, allowing water to flow to the nozzles.

Applications:

Warehouses in low-temperature areas
Unheated underground parking garages
Refrigerated storage rooms

Deluge Sprinklers

This system uses open nozzles that discharge water across the entire covered area when activated. It is particularly suited for environments with hazardous materials, such as chemicals or flammable liquids.

Applications:

Chemical and industrial plants
Fuel or flammable material storage facilities
Installations with a high risk of rapid fire spread

How Fire Sprinklers Are Distributed Within a Structure

Design Parameters for Sprinkler Distribution

Proper distribution of fire sprinklers is crucial to ensure optimal coverage and a rapid response in case of an emergency. According to international standards and the NMX-S066-SCFI-2015 standard, the following are the key design parameters:

Maximum Allowable Spacing: The distance between sprinklers must not exceed 4.57 meters in buildings with ordinary fire risks. This ensures that all areas are uniformly protected.
Coverage Area: Each sprinkler can cover a maximum area depending on the type of structure. For example:
- Residential and commercial buildings with ordinary risks: up to 12 square meters.
- Warehouses and storage facilities with high risks: up to 9 square meters.

It is essential to coordinate the installation of sprinklers with HVAC systems, ensuring there are no interferences between ventilation systems and fire protection devices to maximize coverage.

Importance of Planning in Fire Protection System Design

The design of fire protection systems must be strategically planned, taking into account the building's size, space distribution, and specific risks. Proper planning ensures that:

Sprinkler activation is efficient and localized, minimizing water damage.
Critical areas, such as those with flammable materials or gas installations, are protected with the appropriate sprinkler density.

Collaboration with experts in structural design and installations is essential to integrate sprinklers with other safety systems, such as smoke alarms and evacuation protocols.

How to Install Fire Sprinklers

Fire Sprinkler Installation Process
Installing fire sprinklers requires careful planning and a technical approach to ensure the system's safety and effectiveness. The process is carried out in several key stages:

Initial Building Assessment:
- Analyze the building's structural characteristics, including its size, use, and specific risks.
- Identify critical areas requiring greater protection, such as zones with flammable materials or gas systems.
System Design:
- Plan the network of pipes, valves, and nozzles to ensure an even distribution of water.
- Consider compatibility with other safety systems, such as smoke detectors and alarms.
System Installation:
- Install the pipes and sprinklers in the strategic locations defined during the design phase.
- Conduct functionality tests to verify that the systems activate efficiently in case of an emergency.

Importance of Trained Personnel

The installation of fire sprinklers must be carried out by highly trained personnel to prevent errors that could compromise the safety of the system. Poor design or improper installation can lead to coverage failures or unintended activations.

Considerations for Special Foundations and Slope Stability

In projects built on complex terrains, it is essential to consider factors such as special foundations and slope stability. These aspects can impact:

System Stability: Ensuring that pipes and sprinklers are not subject to deformation or displacement due to ground movements.
Structural Safety: Designing the fire protection system to account for additional loads and the challenges posed by such terrains.
