Cable Passthrough

The title of this page describes a specialised and intricate fire protection problem. Today as more complex buildings are being built to a higher specification the Fireplug Cable Passthrough System (CPT) has been individually designed and then tailored to suit particular aspects of the changing demands of today's specifiers.

The CPT is a unit that can be used to allow a service that can be described as temporary, such as a T.V. camera cable, to pass through a wall/floor yet still maintain the integrity of the wall/floor as designated. What is meant by integrity is that in a fire situation, you maintain stability and insulation along with acceptable smoke stopping. These points are also collated into designing a practical and sensibly operated system.

An example of the type of building that lends itself to require a CPT system is one that the general public frequent regularly, such as sports stadia, concert halls, theatres, exhibition halls. Anywhere that people congregate and where the media, like T.V. camera crews for example, need to access right into the construction, trailing recording cable, lighting cable etc. along with them. We trust the days have gone when a fire door is propped open by an extinguisher (the alternative cable passthrough system!). The following information is intended to prompt ideas and ways of solving problems when you may not have been aware there was any.
