Cabling Installation Issues
Building Structure Cabling Installation Issues
This picture shows a building that is tough to cable. The house has weatherboard walls, flat iron roof and no ceiling roof space.
New Building Cabling Installations
For a new house cabling installation, it has to be cabled before the internal plasterboards are fitted. This will be the same time as when electricians are running the electrical circuit cabling.
It will save the owner lots of money in the long term if the alarms, camera and intercom cables are installed during this time. This is especially true for two storey houses as you will read below. It can be quite impossible to get cables to where you want it to be after the house is finished.
Our CCTV, Wired Alarm and Intercom Kits are very suitable for new Building installations.
Iron Roof vs Tile Roof
A Tile Roofed home is easier to install electronic system cables in. Although the pitch of the roof has a big bearing to cavity access. Due to the amount of space inside the roof space. A roof with a 30-degree pitch is going to have way more space inside the roof than one with a 15-degree pitch. The angle of the pitch has the most bearing when you are trying to access the cavity on the perimeter of the building. When you think about it the space inside the roof gets smaller and smaller as you move towards the outside of the building. I can tell you on the majority of houses there isn't enough space to look down the perimeter cavity from inside the roof. You are laying on your stomach, and you can't fit your head between the roof batons and ceiling beams it's impossible.
If you can't access the cavity on a tiled roof home, it's as simple as sliding a tile back over the top of the cavity to gain access. On the other hand with the iron-roofed home, you need to remove a sheet of iron to gain access which takes a time to ensure that water protection remains intact after the cables are installed and the iron sheet is placed back in place.
Brick Veneer Single Story Building
This type of single story house is the easiest to install cables in. The exterior walls have open cavities that are between the brickwork and interior plasterboard walls.
The internal walls of this house have timber or metal frame with plasterboards on either side. Installation of the cables in these walls would require drilling holes in the roof space into the frame.
Usually, the main issue for this type of installation is the amount of room in the roof space. If the house has an iron roof, then it would almost be impossible to reach the outside walls. Try looking at the pitch of the roof and imagine trying to get to the outer walls from inside the roof space. The amount of room gets tighter and lower as you go nearer to the outside walls. If the roof is tiled, we can slide the tile back to access these difficult areas.
Our CCT, Wired Alarm and Intercom Kits are very suitable for single story building installations.
Brick Veneer Two Story Cabling Installation Issues
The Brick Veneer Two Story building can be separated into two sections. The first section is the top story area, which can also be treated as a single story house as described with all the cabling issues above.
The second section is the ground floor. The first issue for this section is that it is almost impossible to access any internal cavities downstairs because of the upstairs floor being above them.
The external wall cavities are also very difficult to access. If the second story floor is covering the cavity, it would be impossible to get the cable down the exterior wall cavity from the second floor.
Our Wireless Alarm Kits are very suitable for two story building installations.
Single Story Weatherboard Buildings
When you say weatherboard and fibro, it simply means no open cavities anywhere. Every cable that will be installed in the cavity will require drilling. Installation of the cables in the walls requires holes drilled from the roof space into the frame. The main issue is about the amount of room in the roof space. If the house has an iron roof, it would be almost impossible to reach the outside walls. Try looking at the pitch of the roof and imagine physically trying to get to the outside walls from inside the roof space. The amount of space gets tighter and lower as you go near the outside walls.
Our CCTV, Wired Alarms and Intercom Kits are very suitable for single story building installations.
Two Story Weatherboard Buildings
When it comes to Two Story Weatherboard Houses, the second floor can be considered as a separate single story section having the same issues as a single story weatherboard building.
The only way to install cables on the first floor is to run the conduit from the upstairs roof space down to the outside wall.
Our Wireless Alarm Kits are very suitable for two story Building installations.
