Regarding heats on the same loop, the 5601 will place a dead short on the powered 2 wire loop. While it may still trip the panel, none of the sounders on the loop will function. Not a good idea.

Yes it will trip the system, however the bigger issue is whatever is powering the loop in reversed state, if it's the M1, you'll pop a PTC. If it's a supply, you'll either pop a PTC or fuse, or if unlucky and using a non-tolerant unit, let out the magic smoke.
This failure is what I observed in testing the system. "yes it will" is your opinion and you are entitled to it.
OK, now everything goes off at once...BUT for some reason when I went into the Reset Smoke Detectors section of the Elk menu, pressing the right arrow didnt start the reset. Actually had to power down the panel to get it to stop. Im guessing this is not normal
Yeah, the resistors were 800-something. 2WMOD2 definitely connected to SAUX, and the smoke detector reset function seems to work correctly if the RRSMOD portion isnt tripped (i.e. isnt in alarm). The green LED on the 2WMOD2 goes blank for a second, then comes back on solid for a bit (normal, per the manual). Meanwhile the panel gives Fire Trouble, I assume because the 2W is still "booting up". Once the 2W is "booted up" the fire trouble on the panel goes away. I figure this is how it SHOULD work even during alarm, but it doesnt look like it is.

Once acknowledged I attempt to reset the smoke detector thru the keypad menu but pressing the right arrow on the keypad doesnt seem to do anything. Same goes for any other menu choice. Meanwhile the fire sirens are still blaring.

Something else I just tried: the rule I have for output 3 says Whenever Any Fire then Turn On Output 3. Instead I added "for 30 seconds" to the rule, so it *should* have turned off output 3 after 30 seconds, which I thought would turn off the RRSMOD and silence the alarms. Output 3 DID NOT turn off after 30 seconds, the alarms were still blaring and when I went to the panel the RRSMOD was still clicking in the temp 3 pulse.
I find it strange that the databus is getting so saturated with messages during the fire alarm that you can't even enter any commands on the keypad.
Upon fire alarm, does pressing the star key " * " on any keypad do anything, namely silence the alarm?
It's interesting that in the Elk Installation Manual (p. 32) it says
"NOTE: Slow loop response shall NOT be used on Fire zones."
Don't know whether that's a UL or Elk requirement... and whether modifying the loop time will affect how zone definition 11 (Fire 24 hr 'Verified') will operate.
Maybe what's happening is that because you're unable to reset the offending smoke detector during the very brief moment when the RRS-MOD cycle is passing normal polarity power through the circuit, the Elk thinks it sees a NEW fire alarm (from the same detector) because the detector remains latched.
I don't have any experience with 2-wire smokes, but 4-wire smokes do work fine with the RRS-MOD for me.
Another thing to try: initiate the fire alarm from the keypad function button. This would rule out a latched detector.
