		Overview Almost every apartment building constructed within the past year will have had an Integrated Reception System (IRS) installed, giving residents a choice of Terrestrial and Satellite TV plus FM and DAB radio. Around 40% of these will also have included for the new Sky Plus service and we expect that this will rise substantially once the benefits of Sky Plus are fully appreciated. It is not usually possible to upgrade to Sky Plus after first fix stage of construction. The Terrestrial TV service includes where available the new digital Free-View service. Availability of Digital TV can be checked by entering the site post code on the Free-View website http://www.freeview.co.uk/channels/

Cable Specification
If you or your electrical contractor intend to source and install your own coaxial cable, it is absolutely essential that it complies with BS EN 50117 and carries the CAI Bench Mark Number. Failure to comply with this requirement can result in interfering signals causing freezing of digital pictures. The only satisfactory solution is to replace non complying cable. As the problem usually only comes to light after completion, this can be a very expensive error.

Outlet Plates
A basic IRS would typically have a triplexed outlet plate (TV Satellite Radio) located in the lounge as shown in the system sketch. Bedroom outlets are usually extended from a socket adjacent to the triplexed plate allowing for Terrestrial TV and Radio reception. Additionally, the selected program on a Sky Box can be added and the box controlled from the bedroom. Sky Plus requires a second Satellite outlet (and second coaxial feed from the central distribution switch). When selecting the electrical accessory range, it is wise to ensure that the appropriate TV outlet plates are available.

Baltic Quays Newcastle upon Tyne
This development, completed in June 2004, represents a very typical IRS installation. A total of 241 apartments in a series of seven blocks, containing between nineteen and fifty one apartments. The dish and aerial arrays were installed on single 1.5” steel poles mounted through the roof and fixed to the building frame. Amplifiers and Switches were installed in risers connected with a five wire coaxial “backbone”. A single coaxial feed runs from the riser switch to the lounge triplexed plate with an extension to the Master Bedroom.

Ayton School for Wimpey Homes Now 5 years old and at the extremes of system design in 2000.
This development included the conversion of an eighteenth century boarding school with outbuilding and detached cottages plus four new detached apartment blocks with 63 dwellings in total. The entire site covers some four acres and stringent planning restrictions meant that one dish and aerial array would need to serve the entire development. Additionally the array had to be virtually invisible from any ground level observation point.
The system was designed by SIS engineers and used the Philips GII range of amplifiers and switches. Commissioned in January 2001 (pre-dating Sky Plus) to date it has worked faultlessly.
