I don't know about lot numbers, but I just wired my rehab project with brand K smoke and combo detectors. I have two CO/smoke detectors mixed in with about 6 smoke detectors. They communicate nicely. They're wired together like 3-way switches... with 12-3 wire. You've got two for power and one for signal. I don't know exactly how the detectors use that signal wire, but I would think it would be fairly generic. Over a certain voltage means a unit has detected a fire! Alarm!
Anyway, it's something you could easily try. If the unit you buy doesn't communicate with the others, return it... try again. I think if you hold down the test button long enough it will set off the others, right? If not, fog one of them with enough lysol to set it off
