datadiffusion Posted August 22, 2019 Posted August 22, 2019 https://www.ebay.co.uk/itm/ABACUS-REM-UNIT-BRAND-NEW/193054640248?hash=item2cf2f40878:g:2MQAAOSwPUVdWTbJ So are these actually 'digital' or just a very elaborate setup of resistor values? As I notice it connects to a zone, not a databus according to the instructions?? Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands
james.wilson Posted August 22, 2019 Posted August 22, 2019 I'd assume data. The hkc connects some addressable devices via zone inputs Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
MrHappy Posted August 22, 2019 Posted August 22, 2019 w/o digging a book out.... IIRC the rkp & expander where on the same data bus & need a 5th wire for rkp sounds ? Abacus used to use funny resistor values & could have spilt zones (a&b) via resistor vaules or "peardrops" There was an 6/14 with a knacked rkp + expander kicking around my unit floor the other month Quote Mr Veritas God
datadiffusion Posted August 22, 2019 Author Posted August 22, 2019 Instructions are very odd though, which is why I wondered; Connect to Zone 8 'A' terminal for a 16, or any Zone 'A' terminal for a 64, the A+B zone splitter thing I do remember although now don't even have any of these on the books and never any with zems or splits. So presumably replaces the zone in each case? Wasn't the zone splitting sort of 'secret', in that they wouldn't tell you the resistor values but rather tryed to either sell you a box or their own brand PIR which had the 2nd alarm terminals built in?

datadiffusion Posted August 22, 2019 Author Posted August 22, 2019 Odd, data via the Zone then! And also 'clean' power on B and C, and presumably dirty power for the detectors! Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands
