I am in the process of a renovation requiring the installation of wired smoke detectors, and I have an existing IQ Panel 2 system. I have bought the PowerG hardwire translator. I am interested in being able to know exactly which smoke detectors is going off, so my plan is to home run each 4-wire smoke detector (System Sensor) to the hardwire translator and connect each to its own zone. I am aware that this will require each smoke detector to also have its own power supervision relay. Each would receive power from Aux+ and be connected to PGM2 in parallel to allow resetting.
My question is this: if one smoke detector goes off and is then cleared from the panel, that will result in a power reset on PGM2. Will each other smoke detector that is not then triggered recognize a trouble condition since their power would have briefly gone out and their supervisory relay would have communicated an issue? I imagine this would be even worse if I connected the System Sensor polarity reversal module to allow all of the smoke alarms to sound together in a temporal 3 pattern.
The wiring for this can be found in the link below. The wiring would follow the wiring guide but each smoke would be wired into its own zone, correct? Based off the wiring, it looks like the resistor will be seen by the panel regardless of power which means the zones for the smoke detectors will not go into trouble when resetting them.
Another option which would also cost more would be to use an IQ Pro with addressable smoke detectors.
I was planning for all the power and alarm wires to go back to the main panel rather than daisy chaining. I don’t think the diagram you provided would necessarily help me. What it would look like is 1 detector rather than 2 per the wiring diagram. There would still be a supervisory relay and EOL resistor, but there would need to be for each smoke detector. I don’t think there’s a way to daisy chaining power but have the zones separated, since each zone needs its own EOL resistor, and each resistor needs its own supervisory relay.
So that gets me back to the same question: if zone 1 is alarmed and it power resets, it would power reset zone 1 and zone 2. But zone 2 wasn’t alarming so would that trigger malfunction alerts because zone 2’s supervisory relay briefly cycles its power when zone 1 resets?
I was thinking you were using a 4WTA-B which would be Figure 7. By using the RRSMOD you can have all the smokes trigger a sound when one of the smoke detectors activates. This is why I was saying to daisy chain the power as this is what activated the other smokes but have a home run to the panel from each smoke detector each with its own resistor so you can know which smoke triggered the alarm.
If you use multiple RRSMOD’s you will still need to use a reset power programmed PGM and when resetting power, this would cause all of these reset power PGM’s to activate resulting in all RRSMOD’s loosing power briefly.
Oh I see. Correct that is the type of smoke detector I would use. With that set up, I would have independent zoning. But if power went out the end of line supervisory relay would indicate trouble only on the last detector in the power daisy chain right? If so that’s not really a problem since I’d still know there’s a problem somewhere.
