Fences, Dog Kennels, Puppy Houses and Other Projects: Contracting Blogs

Hello! My name is C.J., and as you may have guessed from the title of my blog, I am a huge dog lover. My dog has specialised things in my home like a built-in shelf for his food and water bowls and a dedicated grooming area with a bath. Outside, he has his own shady area, a dog house with a heated floor and a sturdy fence. I worked with contractors through all of those projects, and I hope to do even more. This blog is going to talk about contracting... I hope to start with some posts about the process involved in some of the things the contractor made for my pup but I also plan to include some posts with a more general contracting focus. Take a look and enjoy!

Commercial Fire Sprinkler System: A Guide

Irene Little

How much do you know about the fire suppression sprinkler system which is installed on your commercial premises? Having a little knowledge about your sprinkler system can be very helpful when dealing with a fire safety contractor who has come to perform an inspection of the system. Below is a guide to the different components that make up a sprinkler system.

Stop valve

This valve controls the flow of water from the mains water supply into the sprinkler system. It will normally be located next to the fire control panel. This valve should be locked in the ON position when the fire sprinkler system is active. You should only turn it to the off position if work is being carried out on the sprinkler system.

Alarm valve

The alarm valve is normally in the closed position. When the fire alarm is triggered, this valve will open, allowing water to flow to through the fire suppression system to the sprinkler heads.

Sprinkler heads

This is the part of the fire suppression system everyone sees on a daily basis. They are the small metal valves which protrude from the ceiling of your commercial premises. When activated, the sprinkler heads open and spray water into the space below to extinguish and contain any fires.

Alarm bell

When the sprinkler system is activated, the alarm bell creates an audible warning so that your staff and customers can quickly evacuate the building.

Pressure switch

This switch is located on the fire control panel. When the sprinkler system is activated, it causes the water pressure to drop within the system. This triggers the pressure alarm which is set to alert the local fire department that assistance is needed.

Flow switch

The flow switch is used to monitor the water pressure in different parts of the system. This helps the system to determine which parts of the sprinkler system need to be activated. This means that water will only be supplied to the area which is showing signs of fire. This will prevent every sprinkler in your commercial premises being triggered at once, which can lead to flooding and damaged stock in areas which are not affected by the fire.

Pressure gauge

The pressure gauge monitors the water pressure within the sprinkler system. A fire suppression system will normally have two pressure gauges, one which measures the pressure of the external water supply and a second one which measures the water pressure within the sprinkler system.

If you require any further information about fire suppression systems, you should contact a fire safety contractor.
