Nope.  I don't consider any security panel as a fire alarm system.  A
fire alarm *system* is dedicated to one thing...  A burg panel/security
system can report on a variety of events and doesn't require
specifically "listed" devices to do so.

Nope.  It's a security system.  A fire alarm system is a whole different
"animal".  The OP would have a hard time installing a *LISTED* fire
alarm panel...  for this you would need the proper certifications,
permits, etc.

We're not talking a "fire alarm device" here are we??

No.  It isn't.  It's a burg/security system.

I don't doubt that it is.  Did the OP need to preserve the UL fire
listing or did he simply want to monitor his 110VAC smoke alarms?  I
work with LISTED fire alarm systems all day.  They're manufactured by
companies like Edwards, Simplex, Notifier, FireLite, and Mircom.  Like I
said...  you can hook *any* switch up to a burg panel.  It doesn't have
to be "listed" for the specific purpose.  I can monitor any number of
"points" in my Elk M-1 Gold and none of them have to be "listed" for the
particular purpose.
