Yes.  I would suggest a *supervised* auxiliary power supply and use
power supervision relays (if you're going to monitor smoke status in the
room).  GE makes a DC powered four wire smoke alarm with integral PSR.
The AHJ will often want a system heat detector in each room the GE 448
series smoke alarm will meet this requirement.
