Rik Posted August 9, 2006 Posted August 9, 2006 Hi guys, have managed to get hold of another PSU. my question is this : once i've changed the PSU's over, would i be ok to take all 3 keypads' power from the "aux" supply ? the reason i ask is that I've noticed on the main PCB that there are two sets of pins labelled A, B, +12, -12. They aren't terminal block, but are more like the sort of connector that is used to link the main PCB with the PSU. (hope your following so far!!) does it matter how the keypads are connected i.e. to aux supply or to these connector sets? donat want another PCB going to heaven!!Thanks Craig Yes you will be ok powering 3 rkp's from the aux supply, the 2 molex sockets on the main board are for direct connection of a telecoms module/232 module/ or engineer rkp.
james.wilson Posted August 9, 2006 Posted August 9, 2006 Rik is correct but it looks like you have a 'smart' psu if you have 4 pin connectors on the psu board. Youu wll need to use the transformer that came with it not the old 1A one. re your 3 keypads as long as your day mode current isnt above 500-600 mA you will be fine on a 1A psu although thes ecurrent ratings have changed due to en securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
