What is the difference between conventional and addressable fire alarms?

The biggest difference between conventional and addressable fire alarms is customizability. Conventional fire alarms sit on the wall or ceiling and go off individually when they detect smoke or fire, making them perfect for small buildings such as individual offices or retail shops. Addressable fire alarms, on the other hand, provide specific information about individual detectors that are invaluable if your office is part of a larger building or building complex. Addressable fire alarm systems can be customized to where different devices have different alarm thresholds based on their locations. Addressable fire alarm systems are typically more expensive than conventional alarms, but the extra information they provide to firefighters and building managers is invaluable.

How does a standard response fire sprinkler work?

Standard response (SR) sprinkler heads are best suited for commercial or industrial buildings, including factories and warehouses. They activate individually to prevent causing water damage where there is no fire present. SR sprinklers take longer to activate than quick response sprinklers, requiring the heat from a fire below to reach a higher temperature before the liquid inside the bulb expands, the glass breaks, and water flows through the sprinkler head. SR sprinklers contain 5 mm glass bulbs that take longer for the expanding liquid inside to burst them. That said, these sprinkler heads still react within seconds, quickly dousing any fire.

How does a quick response fire sprinkler work?

Quick response (QR) sprinkler heads are typical in high-density, light-hazard environments, including hospitals, assisted living facilities, office buildings, and schools. They are also often installed in residences. QR sprinkler heads respond faster to the flames below by activating at a lower temperature than SR sprinklers. They have 3 mm bulbs that allow the liquid inside to expand and break the glass quickly. It’s only appropriate to install QR sprinkler heads in applications that are unlikely to have high ambient temperatures that could trigger a sprinkler head without a fire present.

Fire Hydrant Systems

on June 12, 2020

A Fire hydrant system is generally part of a more elaborate fire protection system also known as the backbone of the fire fighting system, which is installed at a particular building based on its size and height. The function of the fire hydrant is to supply water via a hose pipe which is attached to the hydrant at the time of firefighting. The fire hydrants which are commonly used in India are a single body casted product. This allows for there to be minimum chances of leakages and negligible pressure drop during the firefighting process.

There will generally be multiple fire hydrants that would be attached to an elaborate pipeline filled with water using a pumping room. This allows for all the fire hydrants to be simultaneously used for firefighting. The operating of a fire hydrant involves coupling it to a hose pipe which is again coupled with a branch pipe at the other end to provide a proper flow of water. As the average water dispensing capacity of standard fire hydrants in the Indian market is around 450 LPM to 2280 LPM it is very important that this equipment should only be handled by trained individuals. Improper usage can lead a person not to be able to control the fire, there can also be injuries and wastage of water. Fire hydrants come with single, double and even quadruple outlets. The single and double inlets are to be used for firefighting whereas the quadruple ones may be used by the fire department to provide additional water to the existing pipelines of the said building.

Generally, the fire hydrants are provided on each level of the building so water can be sprayed into different areas of that floor by using the hoses. Also, the hydrants are provided along the boundary walls of buildings to be used for dousing the fire externally in case there is a large fire within the building. This allows for the fireman to be at a safe distance from the building while being able to yet fight the fire.

We at Sujay Fire LLP provide all types of Fire Hydrants along with suitable Hose Pipes, Hose Boxes, and Branch Pipes. We also provide a comprehensive fire protection system based on the National Building Code of India and Guidelines given by local Fire Departments.
