House has an older Concord 4 hardwired system. There are 6 zones wired, and I believe a few glass break detectors and smoke detectors. There are resistors (I believe 2k) wired in at the panel on the sensor zones. There are 2 alarm panels, which are hardwired into a central closet that contains the existing panel.
My plan is to replace everything with a primary IQ 4 Panel, and a secondary panel upstairs (where the 2nd panel currently is). My shopping cart is pictured below… just making sure this all looks right. I don’t really understand the difference between the 319.5 and 345Mhz panels, but the 319.5 seems to have more accessories so I went with that. Any other insights appreciated - as far as I know there are no wireless zones in the house (since the current panel doesn’t support them) and I don’t anticipate needing to add any, although you never know.
I want to locate the IQ4 power supplies in the central closet and wire them into the existing cables that go out to the panels to provide power without having to plug them in at the panel somewhere for a cleaner look (I’ll join the 4 wires into two pairs to simulate a higher gauge). It’s not a terribly far run for power.
I’ll also have to replace the power supply for the Concord 4 with the one for the hardwire-16 as the former is AC and the latter is DC; but there’s an outlet right in the closet so no big deal.
If you are looking for support for smoke detectors, it may make more sense, but again, I would recommend determining whether those smoke detectors should even be used. Often older systems will have expired smoke detectors.
The Hardwire PowerG has better inherent range, due to PowerG, a little more power available for a wired siren should one be added, but only supports 8 zones, and it specifically calls for a 7AH battery, which is not commonly found on existing panels, usually they are 4 or 5.
