zone 1 (see photo in post #30) is wired. however, the system currently has honeywell 5808W3s. i assume these aren’t related? what could the wiring in zone 1 be for? i’m not aware of any other smoke detectors in the current system…
Is that a zone currently learned into a Surety account or is this a separate system?
I wouldn’t be able to say for sure what a wire would be connected to locally. You’ll need to check for labeling/sensor zone list written on documentation, or test zones.
I can tell you the resistor is not wired properly for a smoke detector, so it is likely not a smoke circuit.
No, wireless detectors would be unrelated to a wired zone.
would i be able to use the 5808W3s with the 345mhz IQ2+?
Yes, that model is compatible. You can view a compatible sensors list here (see the 345 section.)
does the First Alert 148 comprise both panels in the photo in post #4, or just the larger of the two? if the latter, what is the model of the smaller of the two panels which appears to be the receiver for the wireless sensors?
The main panel is the lower, larger board.
The upper smaller one is a 5881 wireless receiver.
