The Ontario Building Code | Emergency Power for Hospitals
3.2.7.6. Emergency Power for Hospitals
(1) Except as required by Article 3.2.7.7., an emergency electrical power system for emergency equipment required by this Part for health care facilities shall be installed in conformance with CSA Z32, "Electrical Safety and Essential Electrical Systems in Health Care Facilities".
In Plain Language
This clause sets emergency power requirements for fire pumps supplying the sprinkler or standpipe system, since a fire pump losing power partway through a fire would defeat the purpose of the suppression system.
