9.10.19.3. Location of Smoke Alarms
This Article indicates where smoke alarms are required in dwelling units. Since the prime purpose of a smoke alarm is to wake the sleeping #occupants in the #suite in which the fire originated, smoke alarms are installed in each #bedroom and in the #hallway that serves them. To avoid any delay in warning due to the time it takes for #smoke to travel from #storey to storey, and to allow for the fact that other habitable rooms can be used for #sleeping, additional smoke detectors must be installed on other storeys, including #basements.
A smoke alarm installed in the living area and wired to sound another smoke alarm located near bedrooms is the ideal solution (Figure 9.10.-40).
