Guest anguscanplay Posted March 7, 2008 Posted March 7, 2008 telecoms (youd better let BT themselves know that then) and data (two data sources I`d agree) it is simply very bad news to run signals up and back down the same multicore - END OFF hmm so how does it work if it isnt in itself sending signals " up and back down ? " 8 years hundreds of units and NOT ONE failure, so much for your END OF
Alarm Protection Posted March 7, 2008 Posted March 7, 2008 This does work in star or daisy as i have done both. !
Guest anguscanplay Posted March 7, 2008 Posted March 7, 2008 This does work in star or daisy as i have done both. can you confirm the "un resistered.." keypad tampers though, I can see how it would on the cpx etc but not on this as theres no keypad address and no loss of data - its a bit like the 816 will work even if you dont address the keypads but all tampers are kp1 - because each kp has a resister anyone got time to rig one up on the bench?

arfur mo Posted March 8, 2008 Posted March 8, 2008 hmm so how does it work if it isnt in itself sending signals " up and back down ? " 8 years hundreds of units and NOT ONE failure, so much for your END OF hmmm!, who is that has said of me because i don't know regs but claim i install to high standards which i can't do according to you??? i'm surprised you don't seem to grasp this point, in networking it will cause glitches, such glitch 's are vary fro wearisome from slow downs and bottle necks to data corruptions. surely you must understand there could be far worse consequence's on alarms. your claim of 8 years and how many? to justify your blatent wrong doing which is a disappointingly cavalier attitude at best, being way below par for any standards you so often tub thump as inart 'P'. a signal is sent to and and received back from the keypad, but if you then double this situation the NEXT or FEXT via induction can cause a 'ghosting' of the data signals sent/received and can result in a doubling of signals in either direction - that's why it such a bad practice . and is not the advice the manufacturer giveson wiring multiple keypads. you may 'get away with it' but it makes it non the less a very bad practice - enjoy your sleeps. regs alan If you think education is difficult, try being stupid!!!!

arfur mo Posted March 8, 2008 Posted March 8, 2008 YUP! but i'm in very good company at least regs alan If you think education is difficult, try being stupid!!!!
