kuchars22 Posted August 20, 2008 Posted August 20, 2008 Hi, All of my existing cabling under the floorboards is unscreened, and now that I am moving and re-wiring the panel, I've got the opportunity of replacing cables for the bell, radio expander, keypad and internal sounder that are above floorboards. Should I consider using screened cabling whilst I have the chance, or would unscreened be ok? It's a 3 bed house, crossing 240v mains here and there, but not running parallel for more than two meters. I also have an ACT AC inducer fitted to the panel if this helps. Thanks
james.wilson Posted August 20, 2008 Posted August 20, 2008 screening is obviously preferred, but for most installs isnt needed, unless you have a particular interference problem, or your near a large rf source. Putting the cables in the correct place is the better way to go, but if you have the chance you can never have too much cable installed lol securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

The problem is is that I have the consumer unit there, and a wireless router! Is this included as a "No! No!" situation?
james.wilson Posted August 20, 2008 Posted August 20, 2008 you cant run parallel with your mains. I think your router may have more problems being there. If your concerned the screened wont do any harm, and wifi is pretty low power. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
arfur mo Posted August 20, 2008 Posted August 20, 2008 i have a WiFi access point in my loft directly above the panel position (in a cupbaord below it), has radio receiver for pirs and no issues. a lot is made of screen cable on alarms systems, but shortly after the early d10 years of electronics being used in systems it was no longer required. latest standards ask for the keypad to be in screen cable and so are the links to zone expanders (as keypads can be brached from them) but this is mainly for RFi reduction compliance - not for the panels needs. regs alan If you think education is difficult, try being stupid!!!!
