They're wrong.

That's actually a good idea, however, I'd go with 2 wire units (they're
easier to install).  Make sure they're cross-listed to your alarm
control.  You may have to install a reversal module to get all the smoke
alarms to "beep" when one goes into alarm.  If you use 4 wire DC smokes,
you'll need a power supervision relay.
