Technical standard names updated for residential smoke detectors, heat detectors, and fire alarm components

Plain-language summary · AI-assisted · not legal advice

The regulations that set mandatory safety standards for residential smoke detectors, heat-actuated fire detectors, smoke alarms, audible signal devices, and control units have been updated to reference revised ULC standard titles and numbering. The changes are purely to the names and identifiers of the referenced standards — for example, "CAN/ULC-S529" becomes "CAN/ULC-529" and the standard title for heat detectors is updated to reflect the current ULC document name. Manufacturers, importers, and distributors of these products must ensure their goods comply with the newly cited standard editions. No new product requirements are introduced beyond aligning references to the current ULC standard names.
