When putting the wires into a zone on the 16-F, does it matter which of the two ports the wire with the resistor goes into?
No, it doesn’t matter which terminal it goes into of the two, the resistance is the same either way, though I would do it the same way on all zones to avoid confusion later.
Is it possible do something similar with the IQ Panel 4 where I connect or splice it to something in the 16-F panel? Assuming no but figured I’d ask to save myself having to figure out another way to get the panel powered since there’s no power easily nearby.
Depending on the length of the cable you could potentially reuse the wires, but you must not connect the panel to a power source other than the included plug in power supply. Do not connect the panel to the output of the Hardwire 16F.
The included plug-in power supply for the alarm panel can be spliced onto existing wiring if you want to wall mount the panel and reuse that wire.
As long as the run is less than about 50-60 feet, doubled 22AWG cable should be fine. Use two conductors for positive, two for negative.
The way the Concord panel was powered was over a 22 AWG cable that went into my garage. Each pair of wires were twisted together and wired into the old adapter. Can I reuse this cable and safely splice it to the adapter that comes with the 16-F?
This would also depend on the length of that cable run. How long is that cable?
