At around 4 AM on 18 March 2026, a family in Indore’s Brijeshwari Annexe could not open their own
doors. An EV charging point had exploded outside their home, the fire had reached more than a
dozen stored LPG cylinders, and when the power failed, their electronic lock jammed. Eight people
from one family died — including a pregnant woman and a child.
The fire started the tragedy. An electronic lock that was never certified to open in one finished it.
This is the part of fire safety India keeps skipping. We specify fire-rated doors, install alarms, mount
extinguishers — and then hang an uncertified lock on the one door that is supposed to save a life.
Under India’s National Building Code (NBC) and Bureau of Indian Standards (BIS) provisions, a fire
door is only compliant as a complete rated assembly. The moment you fit an untested lock, the rating
on the door beside it is meaningless. The assembly is broken, the compliance is gone, and the escape
route is only as strong as its weakest component — which is almost always the lock.
The numbers say this is a home problem, not a rare one
Fire is not an edge case in India. According to the National Crime Records Bureau’s 2024 data, 5,888 people died in fire accidents that year — about sixteen every single day. Two figures matter most:
the majority of those accidents, 3,585, happened in residential buildings, and electrical short
circuits alone caused 17.2% of fire-accident deaths. Madhya Pradesh, where Indore sits, has for
years been among the country’s top states for fire accidents. This is a predictable, local, home-
centered risk — and the door is the last thing standing between it and the people inside.
Certification is the whole story — here is what it actually means
“Fire-rated” is a claim. Certification is the proof, and in India it is built on a specific, documented
stack. A lock worth putting on a fire door should sit inside all of it:
•NBC (National Building Code of India) — sets the requirement that fire doors and their
hardware performs as a rated assembly for a defined period. This is the code fire officers check
against.
•BS:476-20:1987 — the fire-integrity test standard. A serious fire-rated lock is independently
tested to hold for a rated 2-hour period, not merely “built to resist fire.”
•BIS / IS 3614 — the Indian standard governing fire-check door assemblies and their fire and
smoke performance. Certification here is what turns a marketing line into a code-backed one.
•CBRI (Central Building Research Institute) — independent fire testing and evaluation that gives the certificate its credibility.
•STQC — government quality certification that backs the product’s testing claims.
This is not paperwork for its own sake. Fire departments in several Indian cities have begun rejecting
occupancy approvals over non-compliant fire doors and fake or unverifiable fire-test certificates, and
CFOs at development firms increasingly refuse to carry that liability. When something goes wrong, an
uncertified lock is not a defense anyone wants to make — to an inspector, or to a family. Certification
is simply the difference between a lock that has already faced fire in a lab and one facing it for the
first time in someone’s home.
What a genuinely fire-rated digital lock has to do
Certification proves the lock survives the fire. Design decides whether people survive with it. A fire-
rated digital door lock worth specifying must:
heats past 800°C.
2.Keep working when power fails — reliable battery backup and a defined fail-safe, so a mains
cut (the first thing a fire causes) never decides whether the door opens. This is exactly what
failed in Indore.
3.Open from the inside in one motion — no code, no app, no thought, in smoke and darkness.
4.Have a mechanical override — a physical release for when all electronics are gone.
A lock that cannot answer all four is a convenience product sitting on a fire door. Digital locks — also
called electronic locks — are the future of access in India, but only the certified, fail-safe ones belong
on an escape route.
Where Onetouch stands
We build digital door locks because they are genuinely safer and smarter than the mechanical locks
they replace. We also build them knowing what Indore made unavoidable: a lock on a fire door
carries a life-safety responsibility, not just a security one.
That is why our Onetouch fire-rated digital locks are engineered and independently tested to the BS:476 fire-
integrity standard for a rated 2-hour period, backed by the certification framework — STQC, BIS,
and independent fire testing — that a compliant project demands. Our OT-630 and OT-500 locks are
built so the door that is meant to protect a family behaves like it, from the first alarm to the last
person out.
A fire door is only ever as trustworthy as the lock holding it. That lock should be one that has already
passed through fire — on record, and by the code.
Frequently asked questions
Are digital door locks safe in a fire?
A properly fire-certified digital lock is safe — but only if it is independently tested to BS:476, keeps
working on backup power, opens from the inside in one motion, and has a mechanical override.
Uncertified locks without these can jam and trap people, as in the March 2026 Indore fire where a
jammed electronic lock reportedly prevented a family from escaping.
Do digital door locks open during a power cut?
A well-designed one does, through battery backup, a defined fail-safe, and a mechanical override.
Not all digital locks include this — always confirm it before buying, because a fire cuts power first.
What certifications should a fire-rated door lock have in India?
Look for compliance with the National Building Code (NBC) and BIS fire provisions (IS 3614),
independent fire-integrity testing to BS:476 (typically a 2-hour rating), and credible backing such as
CBRI evaluation and STQC certification.
What is a fire-rated digital door lock?
A digital lock independently tested to keep functioning and hold its integrity in fire for a rated period
— usually certified to BS:476-20:1987 — and installed as part of a code-compliant fire-door assembly
under India’s NBCS and BIS standards.
