Detection, notification and signal transmission. Classed by wiring and supervision level; addressable panels dominate new work. Required in care occupancies at any size, in most assembly uses once the occupant load passes 300, in residential buildings above three storeys or ten sleeping rooms, and in most buildings over three storeys.
The requirement basis is NBC 2020 Div. B, 3.2.4 (determination of requirement, 3.2.4.1). Provincial editions adopt or amend the model code, so the clause numbering in force is the one published by the province — the edition named on this page is the one Securlor reads.
Costs are modelled as a national baseline per building (typical 10,000–50,000 sf retrofit) — $65,000 to $190,000, with a mid-band of $110,000 — then scaled by the regional labour index. Annual inspection and monitoring runs $1,200 to $3,600.
Maintenance is the other half of ownership: annual test and inspection, under NFC 2020 Div. B, 6.3, tested to CAN/ULC-S536. A system that is installed but not inspected is a compliance failure waiting for an inspector to find it.
This page is a planning reference, not a code compliance opinion. The authority having jurisdiction decides what binds a specific building; confirm the requirement and the edition with a qualified professional.
