Question about soldering inside the room

Pretty much what the tittle say Im wondering if soldering in the room with the window open and a small fan pushing the fumes to the window would it start the smoke detector alarm.
I have the novak silver solder it say is lead free with 3% silver and environment friendly

I solder inside my hobby room all the time, and have never set off a fire alarm. I just keep a fan running to disperse the fumes (not even a window open). You should be fine.

If you do soldering 'more frequently', then consider investing in a proper extractor. For my workshop I use a 24V 120mm fan about 100mm from the job, it pulls away the flux fumes and takes them outside. The smoke is burning flux (plant resin) so while it's annoying it's not explicitly fatal, that said, always best to keep all forms of smoke well clear of you.

I set off my smoke detector (which is right over my work bench...on purpose) about 20% of the time. It's annoying, but sure will come in handy if any of my LiPo's catch fire.

It's the epoxy fumes I worry about in my 14'X12' hobby room. I've got no windows (basement) and those fumes seem to hang around for a day or so...

Sign of the times, I guess. I have been soldering stuff since I bought my first iron 50 years ago, including a full radio kit, and re-plumbing my house using a torch. All the yowling about "lead poisoning" etc is just hype; ask any old-time TV tech. You are in far more danger doing a fiberglassing job.

My buddy and I used to build in his 8x12 room, doping and all; we are still just fine after 55 years.

A little common sense goes a long way in decisions like this!

don't worry much about the smoke alarm... but do ventilate, its defintely not good for you, and is very annoying (to me anyways) Target sells some nice tiny fans that would help (4" dia) good for the desk. Provided the alarm is REALLY close, i think you will not be able to tolerate it before the alarm trips.

Keep in mind that there is also lead fumes in the smoke. Not a lot but enough that if you solder enough you should at least have a fan.

FYI that solder will eat your tips!

I've gone through 3 different tips with that solder

I've been told that lead doesn't turn to a gas until 1000 deg F. No soldering irons get this hot.

Found interesting article. Evidently there is a negligible amount of lead in the smoke.

Even negligible, I's still have a fan or ventilation as the smoke is bad.

If you live in an apartment you can solder at the bathroom cabinet with the fart fan on and it should take care of the fumes. Crack a window while you do it.

Solder smoke and Butyrate thinner are two of my favorite highs! Hahahaha. I been doing that kind of hobby work for decades and feel it has no ill effects. However, with thinnner, you do need some fresh air along with it. Wouldn't recommend smoking around it either. LBJ

so even that it say lead free it still have some lead when you solder?
thanks for letting me know about that solder eating the tip that way I just do it all on the same day, dont have access right now to other brands
then it seems that the answer is soldering wont make the alarm go off

I usually use the old standard 60/40 tin/lead solder. The lead-free solders require a really high temperature and just don't work as well for home soldering jobs. I simply try not to breath the fumes (if you see the fumes too much you're probably using too high a temperature). I have never set off my smoke detector. Whether you're using lead solder or lead-free, invest in a good soldering station with an adjustable temperature. I bought a really nice digital one from circuit specialists for about $50.
