Residential Fire Sprinklers

Fire protection is one of the most effective measures for saving lives, preventing injury, and protecting property. In 1666, the Great Fire of London destroyed a large part of the city and killed many of its citizens. To this day, it remains a frightening example of what can happen when building fires go unchecked. A fire in a residential building can spread at an incredible speed, leaving the occupants with very little time to get out. In many cases, the ensuring panic and confusion leads to more fatalities than would otherwise have occurred if the occupants had more time to escape. Residential fire protection is designed to give the occupants extra time to make it to an exit.

The two main types of residential fire sprinkler system are the dry-pipe and wet-pipe. The pipes of a wet-pipe system contain water at normal mains pressure, but the pipes of a dry-pipe system are full of a pressurized gas, usually air or nitrogen. When heat from a fire causes one of the fire sprinklers to open, the water or gas inside the pipes flow out of it. The pressure of the gas inside a dry-pipe system is greater than the atmospheric pressure but less than the mains water pressure. The check valve is designed in such as way that the pressurized gas keeps it shut, despite the water on the other side having a higher pressure.

A fire sprinkler is basically a tee-piece connected between two pipes. It is designed to suppress fire by dispersing water over a large area. This is done by a deflector plate on the end, which is a small disc with radial cuts that fan the water outwards. A residential fire sprinkler is a special type that has been designed to blend in with the roof of the building. It may be painted a certain color to match the roof, it may have shiny chrome plating, or it may be recessed into the roof. This type is not used much in commercial buildings because it costs far more than a regular fire sprinkler, and using lots of them can increase the cost of the system by a huge amount.

A residential fire sprinkler may look different but it works in the same way that a regular fire sprinkler does. A tiny glass bulb in the middle keeps a cap pressed against the outlet, stopping the water or gas from flowing out. Heated air from a fire rises to the roof, causing the temperature of the bulb to rise and its contents to expand. When the bulb breaks, the cap falls away from the outlet, allowing the water or gas to flow out. Each bulb has a specific color that indicates the temperature at which it breaks. Fire safety regulations specify what temperature the sprinkler must activate in certain locations around a building.

Regular sprinklers stick out from the roof by several inches, which makes the roof look cluttered and unattractive. They are not the most desirable choice for an upmarket building, such as a hotel or restaurant. Fortunately, there are recessed sprinklers that are much less noticeable. They sit almost flush with the roof, and some even have a cap to cover the large hole. When heat from a fire sets off this type of residential fire sprinkler, the cap pops off and the deflection plate pop downs. The only drawback to using them is their high cost, which can make an already expensive system even less affordable.

As mentioned already, installing a fire sprinkler system is very expensive, but it costs even more to install one in a building that has been completed. Parts of the walls and roofs often need to be demolished and rebuilt just to install the pipes. There is also the problem of choosing a residential fire sprinkler that suits the interior. Given all these problems, it is not surprising that most homes owners rely on smoke alarms for fire protection. Unless you are required by law to have a system installed, there seems to be little point in spending a lot of money on one.
