Fire Sprinkler System Installation
Designing the Fire Sprinkler System
During the initial consultation, our fire sprinkler installers will produce design blueprints of a sprinkler system that meets your requirements. Utilising AutoCAD technology, we will be able to visualise the sprinkler system and calculate the pressure and surrounding water supply. Every step of the way, we work closely with our customers, keeping them in the loop during the initial design stages.
In cases where the available pressure and water flow are insufficient, our experts recommend alternatives. At RAD, we supply mist sprinklers, which operate similarly to residential fire sprinklers. However, they require a lower supply of water and are adaptable
to smaller properties.
Sprinkler Head Positioning During the Design Process
Using the AutoCAD software, our experienced designers will also show you where the sprinkler heads will be positioned in every room ensuring that they line up with the lighting design where required. With plenty of experience, our fire sprinkler installers are very experienced at following design drawings to ensure that the installation runs smoothly.
The optimum position for concealed pendant fire sprinkler heads is in the centre of the ceiling. However, as more and more downlights are installed within residential properties, there is a greater demand for sprinkler heads to line up with as many ceiling fittings as possible. Here at RAD, our designers have considerable experience in lining the sprinkler heads with other ceiling-mounted items while ensuring that the head is positioned within its design limitations. Make sure you state your specifications and how you want the overall design to look and let us accommodate your requirements!
During the Fire Sprinkler Installation
When it comes to the fire sprinkler system installation, our pipework, electrical and plumbing fixtures are installed simultaneously. Working with professionals in their respective industries, we will find the most efficient and direct route from the water supply to the sprinkler heads. No matter the positioning of the sprinkler heads or the floor level they are on.
The external diameter of pipework is generally 35mm-42mm for the riser and 28mm-35mm for horizontal pipe runs.
If pipework travels at right angles to joist work, each joist will be drilled on the centre line of the joist at a point between 0.25 to 0.4 of the joist length wherever possible. Modern TJI and eco-joists facilitate the installation process considerably.
Once the pipework is in position, the sprinkler heads are connected and yellow temporary plastic covers are left in place for protection during the continuous build process. There is only a very small amount of adjustment available for the fire sprinkler heads so it is important that we are told what the overall thickness of the ceiling finish will be.
The system can now be pressure tested and left at pressure until we are called back at 2nd fix stage.
The installation process on high rise projects is different in that we are fixing to the ceiling slab with steel studwork and need to be careful to ensure that the sprinkler heads are installed at the right height relative to the metal ceiling tracking.
Sprinkler Heads
Concealed Fire Sprinkler Heads
These are by far the most popular choice amongst homeowners for obvious reasons. Concealed fire sprinkler heads are perfect for blending into your interior decor and making themselves scarce, unless a fire is present. Concealed sprinkler heads work on a 2-stage basis.
As the heat rises, the first stage comprises the white ceiling cover plate, becoming un-soldered and dropping to the floor. This allows the deflector plate to drop to a position just below the ceiling. A further rise in temperature will then trigger the sprinkler itself, which becomes the second stage.
Traditional Pendant Sprinkler Heads
These are rarely used in residential situations, being far more obtrusive than concealed sprinkler heads. Traditional pendant sprinkle heads overtly show the mechanics of the system and clash badly with modern design concepts. The water is ejected in a conical spray pattern using a convex deflector. Unlike concealed fire sprinkler heads, the pendent sprinklers will be visible after installation.
Sidewall Sprinkler Heads
Sidewall sprinkler heads are mounted onto the walls or beams in tight spaces. Although we stock sidewall sprinkler heads, we tend to find that these are not used as frequently as pendant heads. This is partly because they create a greater demand for the available water supply and the coverage can be obscured by any large items nearby.
No matter the choice of sprinkler heads, our team of engineers and fire sprinkler installers will make sure the installation is performed correctly and efficiently. Every step of the way, our fire sprinkler installation company are there to answer any questions and provide guidance throughout the process.
Fire Sprinkling Testing
Once everything is installed, our professional engineers will go through a series of checks to ensure everything is correct and runs smoothly. We will label various components and run through the different stages with you, making sure you are aware of how the sprinkler system will activate if a high temperature is detected.
Protection of Sprinklers During Construction
Once the pipework is in position, the sprinkler heads are connected and yellow temporary plastic covers are left in place for protection during the continuing build process. There is a only a very small amount of adjustment available for the fire sprinkler heads so it is important that we are told what the overall thickness of the ceiling finish will be.
The system can now be pressure tested and left at pressure until we are called back at 2nd fix stage.
Plastic Covers removed
The plastic covers which protect the sprinkler heads project below the ceiling level to ensures the plaster board is cut around the heads when fitted. The plasterer then plasters up to the covers and the decorator can paint up to them as well.
Installation of Pre-finished Cover Plates
The 2nd fix process is relatively straight forward. The plastic caps are removed and pre-finished cover plates are installed which cover the ragged edge left by the caps. If we are supplying a fire alarm and/or a pump, these will be installed at this stage.
Checks and Testing
Usually carried out at the 2nd fix stage. Our engineers will go through a series of checks and once the appropriate labelling etc is in place the system will be equivalence tested in order to ensure that the fire sprinkler system will perform adequately if required.
