The Ontario Building Code | Vacuum Cleaning System Shutdown
3.2.4.14. Vacuum Cleaning System Shutdown
(1) A central vacuum cleaning system serving more than one suite or storey in a building equipped with a fire alarm system shall be designed to shut down upon actuation of the fire alarm system.
In Plain Language
This clause sets requirements for how a fire alarm system must be powered, generally requiring both a primary electrical supply and a standby power source (such as a battery), so the system keeps working during a power outage.
