Depending on the enviroment, will depend on what type of smoke detection should be used. Ionisation smokes are good at detecting smoldering fires like bedding and furniture. Optical are ideal for detection of visable smoke, and reduce false alarms. If you can give us more information on type of system, building etc we can try and advise.

How do you get around 10 - 12 on a drawing? surely they are either there or they aint?

Would be an idea to contact the manufacturer of whichever system you are planning to use as I think some are limited to 10 heads max interlinked.

So you are using mains linked detectors, Optical will be the best to used in circulation areas such as landings. If the house has more than 2 floors, then a full fire alarm is required.
Aico can interlink upto 20 firdex can use upto 12 in one link
