You want a whole building system or just one room?
Here's the first thing I found:

1 room with pullstation and strobe alarm.
that link isint so good

You just want "an alarm" then, not a fire-specific one.
All you need is to get the parts and assemble them, do you know where to get pull stations, wire and strobe alarms?

no 1 alarm and pullstation but a fire alrm type
That's a short comment. I'll take "no" to mean that you don't know where to get things? I had a quick look: http://www.cooperfire.com/jsb-products/ul-range/addressable-pull-stations/addressable-pull-stations

Those are going to be REALLY expensive!!!
Go look on eBay. I bought a FireLite BG12 pull station for $15 BRAND NEW
and a wheelock horn strobe + strobe for $15 all together too!
Then I bought a 12V AC adapter and I was GOOD TO GO :D
I built a PVC stand for the pull station and Horn + Strobe, ran the wiring inside.
It cost me less than $40!!!!
