I've been meaning to get around to this for years but have been putting it off. My current house smoke detectors are 18 years old. They are 110v ac and tied together.
Questions:
1) Can I reuse the 3 wire romex for 2-wire smokes? They are not tied in series but rather more like a tree (shortest runs to get them all hooked up), so several of them terminate at the end of a run. Can I use a terminating resister on several leaves?
2) If I want them to all go off together like they currently do, I assume I have to use a PRM-2W?
3) In alarm current is 480 ma (for all 8) and since I already need to add a few other things, I've decided I need to add more power from a 5204 or a 5200.
4) Would the PRM be powered off the 5204 AUX? Where does the ground wire of the PRM go? The BLK terminal of the 5204??
5) On the PRM (http://cms.dsc.com/download.php?t=1&id=13050) it says C and NO go to Panel Fire Zone. Where? PGM2 and Zone Common? Would it make sense to use O2 on the 5204 instead?
6) Triggering polarity reversal. The PRM install sheet is confusing. What do I do with T1 and T2? If I select option B, it says T1 is not used and T2 is hooked up to the Bell. Does that mean that the alarm bell has to sound in order for the smoke detector sirens sound? If I don't want that, then do I need option A? Does this mean I need a relay? What does it mean "To Panel Fire Alarm Trigger"?
7) Can I use the same tranformer for both 5010 and 5204 since the power requirements of both those boards are way lower than the capability of the Elk 30 VAC transformer I have?
8) Would it make more sense to add another cabinet or should I just get a larger cabinet that would hold it all? If so, what would your recommend?
9) At the top of the second page of the PRM install guide, it says the PRM must be installed "beyond the last detector". What does the mean? The end of a serial run? But the diagram shows it at the beginning, not the end and it shows a terminating resistor at the end.
