Hello I'm looking to see if anyone can help I've recently bought a eurosec cpx control panel and I was wondering if I need to wire an additional power supply so I can connect the 7 pir's and 4 shocktec door contacts, Or is it possible to power them via the aux 12v. The pir's nominal current is 16mA and the door cont's 7.5mA, according to my calculations this will over-load the system. If so can anyone recommend a suitable add. power supply so I can split the load.
