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.

Which type of building require Fire Hydrant System?

All buildings above 15 meter, Irrespective of height Hotels, Educational Institutions, Hospitals, Assembly, Business Centers, Industrial Properties, Mercantile need fire hydrant system.

Fire Extinguisher Hydro Testing

Fire Extinguishers have to be checked regularly, as per manufacturers recommendation and relevant IS code the extinguishers have to be refilled annually or every 3 years (For ABC Type Fire Extinguisher). Before refilling the extinguishers are Hydraulically tested to check the metal body of fire extinguishers for their strength. Hydrostatic testing involves subjecting the fire extinguisher cylinder to pressures that exceed its rating to ensure it is still capable of maintaining the pressure necessary to discharge properly in the event of a fire.

Apart from Hydraulic testing below points should be checked during annual maintenance of Fire Extinguishers. Cylinder threads that are worn, corroded, broken, cracked or nicked. Corrosion on the cylinder that has caused pitting. Dents that are deeper than 10 percent of their surface Area. Any evidence of repair or that the extinguisher has been misused. Any evidence that the extinguisher has been exposed to excessive heat, fire or flame.
