Been asked to look into a fire detection system for a small factory unit, upstairs is all office space but down stairs is a metal workshop, lots of welding drilling & all manner of smoke producing work going on. (I've passed the job over but curiosity has the better of me).
Anyway my question is; due to the high possibility of smoke/fumes produced in a working day downstairs, could the smoke detection heads be done away with & manual call points be used at exits & base of stairs instead?
