Delhi (NCT) fire-safety compliance.
NBC 2016 baseline plus Delhi Fire Service (DFS) — design-stage triggers for sprinkler, addressable fire alarm, voice-evacuation PA, wet-riser and Fire NOC. Voice-evacuation PA is mandatory from 17.5 m in Delhi — 6.5 metres below the NBC baseline. DFS independently inspects every renewal and the occupancy certificate is refused without a documented test report. The procedural depth is the operational reality.

Consultant note
New Delhi and NCT: DFS renewal-cycle inspections are non-negotiable. Build the test-report cadence and the cause-and-effect matrix archival discipline into the operations scope from day one.

2 systems not triggered at this profile →
- Smoke control + horizontal evacuation zones — Healthcare occupancies require horizontal evacuation between fire-rated compartments and active smoke management.
- Foam / gas suppression for special-hazard zones — Industrial occupancies with combustible-liquid or special-hazard storage need foam, CO₂ or clean-agent suppression in addition to sprinklers.
Local authority verification
Output is a design-stage scoping aid only — it does not replace a licensed fire-engineer's stamp or a Fire NOC submission. Verify every triggered system against the latest gazette of the Delhi Fire Service (DFS) and the local Fire Authority interpretation before drawings carry a fire-system stamp. Send the project drawings and we will mark up the fire-safety scope with citations within two working days.
How the tool resolves a profile
Three inputs · two layers · one indicative scope.
· Why local-rule resolution matters
A residential developer planning an 18-metre block in Delhi (NCT) would, on the NBC 2016 baseline alone, scope sprinklers, addressable fire alarm and wet-riser. Layer on the Delhi Fire Service (DFS) rule and at least 1 additional system trigger appear at this height. Getting that list right at design stage is what stops a tendered building from needing a second-round retrofit at OC stage.
