A building needs to be safe enough for people to live or conduct their businesses. This means it has to pass the strict standards of the Building Code of Australia (BCA).
Among the important matters that the BCA addresses is a building’s fire resistance, as mandated by the Australian Standards 1851. AS 1851 ensures that each building complies with safety standards for fire protection. Sprinkler systems are required to comply with basic standards to ensure effective operation when required ‒ which may depend on the quality of one component such as a unipipe fitting.
For building owners considering fire protection, here are four types of fire sprinkler systems:
This type of fire sprinkler system, when not in use, contains compressed air. Water only passes through the system when the air exits after it detects smoke or heat that activates the pre-action valve. If it’s not a false alarm and there’s really a fire, individual sprinkler heads will then release the water onto the flames. The system best suits places that contain easily water-damaged items such as libraries and data centers.
This is similar to the pre-action system in that compressed or pressurized air occupies the pipes until water is actually needed. There’s a delay of a minute or so before water is discharged, which suits buildings that have a low temperature since it avoids pipes from freezing.
As the name implies, the system contains water in the system at all times for a quick response. This type of fire sprinkler and is designed for high-rise or office buildings. It’s easy to maintain and cost efficient.
This system features open nozzles in addition to a smoke or heat detector. Industrial parks and buildings that contain storage tanks usually employ this system to take care of flammable liquids that spread across the floor.
Having the appropriate fire sprinkler system is one step for a building to pass the country’s safety standards. Owners also need to set other fire safety features as well as an evacuation system.
