Guest Oxo Posted July 24, 2010 Posted July 24, 2010 the start late finsh early skill set rides again...... Hmmm you obviously mean the others there
arfur mo Posted July 25, 2010 Posted July 25, 2010 used to get pos & neg tamper ccts for t & w/ foil etc (check out 9100 cct board) due to panel designs not catching up, especially on companies who made ther own 'in house' there was an 'in between' period where only the neg 'leg' was 24 hour, with the pos leg passed through door contacts etc. so only active when the alrm was armed On the last co i worked for, the panel had a single e.o.l resistor circuit just for wiring and foil purposes, meant freeking miles of foil and frames on one zone , if you had a fault you first played 'find the eol resistor' for an hour or two . you'd scoff at doing so now, but this as common practice, you were simply used to finding eol batteries, so searching for the ressistor was just another accepted practice. Brocks (iirc) used a panel with where diodes were placed across the contacts, during the day the loop was montired as current passed through the diodes on open doors, when the panel armed zone voltage/s were reversed so an open door would prevent setting, its the only panel i know of that did reverse the zone voltages, not sure how they copped with BS.4737 for D/P and tamper needs, as i never actually worked on one. as for 9100' simple DP zones, 9800's its a shared common + pole for each 2 zones, so if the alarm loop did change polarity when set as 24 hour or PAB zone, it would not comply with BS.4737 in that state having also a negative anti tanper loop, you would also 'loose' 2 D/P zones to achieve one 24 hour zone.

arfur mo Posted July 25, 2010 Posted July 25, 2010 I wasn`t speaking to you, I have you ignore, I dont care what you would do in any given circumstance but as in this case usually a "friend" sends a message saying have you seen what old coots said now, they mean well but to be fair I just wish you would do one. seeing as i'm now off ignore with you as you have answered me direct in other threads, for the benifit of all can you please tell me how you wire an O/C PAB into a DEOL zone to give Panic Signal via the panel on a deliberate action? keep it simple, we both know the G595 pretty well, so lets say referring to that panel Arfur bet i'm back on ignore again If you think education is difficult, try being stupid!!!!

IAS Posted July 26, 2010 Author Posted July 26, 2010 single resistor and a short between 2 zones of different polarities you`ll need a panel that changes polarity to get it to work 24hr .......... seriously.
james.wilson Posted July 26, 2010 Posted July 26, 2010 no you wouldnt. You can take ref from the 0v or 12v rails. Some inputs might need a 5v rail if so use a pos zone. We do this now on galaxys which are 0v referenced circuits. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

arfur mo Posted July 26, 2010 Posted July 26, 2010 what a pointless question no Paul, the point is you crowed on about 'never noticed the extra hole' in a PAB, well it won't work on EOL systems in OC -WILL IT! and you think your better than me - dream on! Arfur single resistor and a short between 2 zones of different polarities which will NOT result in PA signal being given from panel, at best a 'Can Not Set' from the client. Arfur If you think education is difficult, try being stupid!!!!
james.wilson Posted July 26, 2010 Posted July 26, 2010 sense of humour failure? no sorry mate, was just a reply. which will NOT result in PA signal being given from panel, at best a 'Can Not Set' from the client. Arfur im afraid not arf. If the circuit is programmed as PA it would indeed send a PA if that was required. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
