omega1 Posted March 6, 2008 Posted March 6, 2008 Hi I need to fit two keypads to a eurosec cp8 panel. It looks like the keypads have to be wired in series according to the manual. Is this correct or can both the keypads be wired directly from the panel with the 680 ohm resistor fitted on both keypads. Thanks in advance Kevin

ViperMK2 Posted March 6, 2008 Posted March 6, 2008 They are actually wired in parallel so wiring them both from the panel is ok but remove the resistor on the shortest run RKP, leave the resistor in the longest run RKP As the days go by, we face the increasing inevitability that we are alone in a godless, uninhabited, hostile and meaningless universe. Still, you've got to laugh, haven't you?

ViperMK2 Posted March 6, 2008 Posted March 6, 2008 Look, parallel As the days go by, we face the increasing inevitability that we are alone in a godless, uninhabited, hostile and meaningless universe. Still, you've got to laugh, haven't you?
Guest anguscanplay Posted March 6, 2008 Posted March 6, 2008 Look, parallel yes and no LOL - its series because it goes to one then the other, but its parallel to the first connection LOL ( if only you knew how often me and " some friends" have the same argument) I always bring the D1 D2 back to the panel on a spare pair then take them out to the second keypad - hang over from the old days I suppose what I`m trying to work out is doing it your way ie pure parallel - is hows the keypad without the resistor tampered? you dont give it a keypad ident like the CPX

But it works in star or daisy.

arfur mo Posted March 7, 2008 Posted March 7, 2008 and you got the cheek to start your post with the words "bad practise....." if it WAS real data I`d agree with you but then we would all be using screened cable too so please tell me Angus, i'm very curious - if the data lines (and the manual indicates they are ) are NOT actually data, how does the keypad communicate with the end station? - mirrors - flashing lights - brail or SEMAPHORE? telecoms and data it is simply very bad news to run signals up and back down the same multicore - END OFF, but you can make yourself look nearly possibly even more foolish - arguing it. regs alan If you think education is difficult, try being stupid!!!!
