Aspirating Fire & Smoke Detection System – How Does It Work?

Key Takeaways:

  • An ASD system can detect fire at its earliest stage and from a long distance.
  • They are easier to maintain and can be accessed for cleaning and replacement.
  • ASD systems have a superior filtration system which eliminates false alarms triggered due to dust or other particles.
  • ASD systems are generally used in critical facilities such as server rooms as they can detect fires early and prevent them from causing any damage.
  • When choosing a fire alarm, it is essential to consider the specific needs of the building and the people who will be using it. 

An aspirating fire and smoke detection system (ASD) is beneficial for businesses where continuity is essential, the environments are relatively challenging, and time is required to ensure safety.

The fire alarm system uses continuous air sampling to provide the earliest possible warning of a fire hazard. It buys enough time to initiate an appropriate response and investigation procedure.

Moreover, it also helps prevent injuries, business disruptions, and property damages. Let’s discuss some important details about the Aspirating fire & smoke detection system to help you realize its necessity.

How Does the Aspirating Fire & Smoke Detection System Operate?

The Aspirating fire & smoke detection system uses a fan to draw in air from the protected premises through a network of small-diameter pipes. Air samples are constantly drawn into a detection unit, passing them over an optical sensing chamber.

The sensing chamber contains an infrared light source and a detector. As particles in the sampled air stream pass through the sensing chamber, they will scatter or absorb some of the infrared light.

The amount of light scattered or absorbed is proportional to the particle size; larger particles will scatter more light than smaller particles. The detector measures the amount of scattered or absorbed light.

It generates an electrical signal processed by microprocessor-based electronics within the detection unit. This signal is compared to preset criteria programmed into the detection unit’s software. If the requirements are met, an alarm is initiated.

Benefits Of Installing an Aspirating Fire & Smoke Detection System

There are various benefits of the ASD system over any other traditional fire alarm system. Let’s discuss some of these significant benefits:

Works Well in Most Environments

Aspirating fire & smoke detection systems can be used in various environments like office buildings, shopping malls, factories, data centers, and warehouses. The system is not affected by drafts, air currents, or high ceilings.

Long Range and Early Detection

An ASD system can detect fire at its earliest stage and from a long distance—the farther the smoke travels, the more time it has to be detected.

Faster Response Time

An alarm is generated as soon as the fire is detected, which helps evacuation and fire control procedures.

Lesser False Alarms

Aspirating systems draw samples from a designed pipe network covering the entire protected area. This results in reduced chances of false alarms.

Easy To Install and Maintain

ASD systems are easier to install as compared to other fire alarm systems. They are also easier to maintain as the sensors can be easily accessed for cleaning and replacement.

Highly Sensitive

Aspirating systems are more sensitive than traditional fire alarms and can detect even minute traces of smoke.

Reduces Operational Costs and Risk

Aspirating fire detection systems help reduce operational costs by early detection of fire. This also reduces the risk to life and property.

Better Filtration System

Aspirating fire detection systems have a better filtration system, eliminating false alarms triggered due to dust or other particles.

In What Places Does an ASD System Work?

Old And Dusty Storage Areas

ASD systems are often used in old and dusty storage areas where traditional fire alarms would not be able to function correctly.

Areas With Restricted Access

ASD systems can also be used in areas with restricted access, such as data centers and server rooms. It’s because they don’t require any physical changes to the structure of the building.

Gas Extinguishing Areas

ASD systems are also used in areas where gas extinguishing systems are installed. They can detect fires before they even start and prevent them from happening.

Open Warehouses

Open warehouses are often difficult to protect with traditional fire alarms. This is because the smoke from a fire can quickly disperse and be undetectable. ASD systems, however, can detect fires in these kinds of areas promptly and efficiently.

Business-Critical Facilities

ASD systems are generally used in business-critical facilities such as data centers and server rooms. It’s because they can detect fires early and prevent them from causing any damage.

Components Of an ASD System

An ASD system typically consists of four main components:

  • A network of pipes
  • A fan
  • A fire detector
  • A control panel

The network of pipes is installed in the ceiling of a building. The fan draws air through the pipes and into the fire detector. The fire detector then analyses the air for any signs of fire. The control panel will activate the alarm and notify the authorities if a fire is detected.

Here’s some more information about the uses of fire alarms.

ASD System Vs. Traditional Fire Alarms

ASD systems are more effective than traditional fire alarms for several reasons. First, ASD systems can detect fires before they have a chance to spread. The system constantly draws air into the detector, which means it can detect smoke and heat even if they are not yet visible.

Moreover, ASD systems are less likely to cause false alarms as the detector only triggers the alarm if it detects a certain level of smoke or heat. On the other hand, traditional fire alarms can be triggered by various things, such as dust or steam.

They are also easier to maintain than traditional fire alarms. This is because there are no sensors to clean or replace. The only maintenance that is required is to clean the filters occasionally.

ASD systems can be used in various facilities, such as office buildings, warehouses, and hospitals. They are also becoming increasingly popular in residential applications.

On the other hand, traditional fire alarms can cause many false alarms, which can be costly and disruptive. ASDs are much less likely to cause false alarms because they only trigger the alarm if there is a certain level of smoke or heat.

What Factors to Consider Before Installing an ASD System?

  • The size of the building: ASD systems are effective in more significant buildings because they can cover a larger area.
  • The type of building: Specific facilities, such as those with high ceilings or windows, may not be suitable for an ASD system.
  • The budget: ASD systems can be more expensive than traditional fire alarm systems. Still, they are less likely to cause false alarms, saving money in the long run.
  • The level of security required: They are often used in high-security applications because they are less likely to cause false alarms.
  • The level of fire risk: These systems may be more appropriate for buildings with high fire risk, such as those with flammable materials.

When choosing a fire alarm, it is essential to consider the specific needs of the building and the people who will be using it. Aspirating fire & smoke detection systems can be an effective way to protect people and property from fires. By understanding the pros and cons of these systems, you can make the best decision for your specific needs.
