The number of canisters required is somewhere between 4 and 200.

Are these detectors all on the same floor? Are these even in the same building?

Ceiling heights? Dispensing and clearing kit used?

Is this a moderately clever spam for Solo?

Well, okay...

Maybe figure about 5 minutes per room to smoke the detector, verify the correct signal and response, and clear the detector. Add some time to travel to the next room on the floor. Continue this trend until all the rooms on a floor have been tested, as well as the ones in corridors, elevator shafts, mechanical closets...

Add some time to ready yourself for the next floor, and start it all over again.

This will give you some idea about how long the canisters will have to last. Divide this time into the manufacturers stated generation time per canister and you will have an educated guess at the number of canisters required. If the supplier is far away and extra cans are an extended delivery, I would add about 25% as a safety. If the supplier is in town and it isn't a big deal to get more, maybe only one extra can would be good.

The suggested 5 minutes is an arbitrary number on my part. Perhaps practice a few, and see what sort of time you actually experience.

This all assumes that all units test and report correctly. Retesting will, obviously, duplicate this scenario.

I'm going to leave the 2 meter ceiling height alone... but pretty sure that isn't correct.

If you are performing a commissioning for someone else, and being paid to do so, find the application specification and follow it.

Or, to be sure the installation is acceptable, AND SAFE, hire a contractor who knows how to do this.

Doing it wrong could kill people, after you have collected your money and left the scene of the crime.

Hire someone!!!!!
