MrHappy Posted July 22, 2010 Posted July 22, 2010 pretty sure but we are trying to remember something from 1986 (last time I read a manual) seem to remember it been when proggramable zones became the norm. I only recall alarm & tamper circuits being pos & neg? I assumed defined un 4737 ? Mr Veritas God
hpotter Posted July 22, 2010 Posted July 22, 2010 I only recall alarm & tamper circuits being pos & neg? I assumed defined un 4737 ? used to get pos & neg tamper ccts for t & w/ foil etc (check out 9100 cct board)
IAS Posted July 22, 2010 Author Posted July 22, 2010 used to get pos & neg tamper ccts for t & w/ foil etc (check out 9100 cct board) the original "double pole" .......... problem was when we started selecting zone type you could have two positives side by side, you should alternate pos/neg in joint boxes too lifes too short.
hpotter Posted July 22, 2010 Posted July 22, 2010 lifes too short. too right, buy a box of resistors..
james.wilson Posted July 22, 2010 Posted July 22, 2010 lol I stand corrected then. Im amazed that a panel would change its polarity. I know the gal dont do it, not the castle. But thats the limit of my proper knowledge. Thanks for checking hpotter, and sorry paul.

IAS Posted July 23, 2010 Author Posted July 23, 2010 You could have got away with it as the 9651 doesn't do it we were talking about the CU`s from before you were born, quite literally.
arfur mo Posted July 23, 2010 Posted July 23, 2010 can use invert attrubute to allow connection of those oc pa's arf mentioned. Though why you would beats me. (how do you do fsl on oc pa/pm? - feel a thread split coming on ) 85en that is. you have no need to worry, the OC PAB was killed off a long time ago , Arfur but if you ever need to, use a simply 'unerversal relay' to interface it, this likely only affects me - due ti the age of some of my systems lol! Arfur we were talking about the CU`s from before you were born, quite literally. i wonder how many on here would still recognise the terms 'lock block and coffin' and 'monoptic ray'? Arfur no, its not a secret masonic password If you think education is difficult, try being stupid!!!!
IAS Posted July 23, 2010 Author Posted July 23, 2010 you have no need to worry, the OC PAB was killed off a long time ago , this likely only affects me - due ti the age of some of my systems coughs - OC panic button panels (on service) second one has the "new fangled charging circuit" technology.
