Qolsys IQ Power Barrel Connector Spec

Thanks for that information, I have measured the O.D. of the Qolsys 90 degree barrel connector and it is 4.02mm, the inside diameter of the connector is harder to measure so will try to experiment a bit. My wall positions for the control panels are about 20 meters away from the mechanical room and the wiring is four conductor JKT (22 gauge) formerly used for DSC control wiring and 2 conductor stranded power wire which appears to be slightly larger than 22 gauge. Anyway, am planning on 3 conductors for each side of the 2 wire power for the Qolsys 9104-840 Remote units which require 7 VDC at about 1 Amp, so hopefully 3 22 gauge conductors will carry that for 20 meters. I'll measure voltages under load and determine what's happening next week, also planning on relocating the TELUS IQ Panel 4 equipment to the 2nd floor of our house as its present mounting location is inconvenient to say the least. As for the power barrel connectors, once the correct size is determined, will be getting pigtailed versions if possible, not really interested in trying to solder and insulate these tiny power connections on the plugs myself. Will post results here as things progress, I really believe that this repair could have been handled without replacing my DSC system, but TELUS bought out the alarm company that originally installed the DSC equipment so my options were limited. Thanks for your suggestions...
