What Is a Fire-Rated Door Lock?
A fire-rated door lock is locking hardware that has been evaluated — as part of a complete, tested door assembly — for how it performs when the door is exposed to fire. It’s not a marketing label. It’s a specific engineering answer to a specific question: when this door is fitted with this lock, how long does the assembly hold back fire and heat?
That distinction matters more than most product pages let on. A digital lock doesn’t earn a fire rating on its own — it earns one as part of the door, frame, hinges, and seals it was tested with. Swap any one of those components for something untested, and the assembly’s fire performance is no longer guaranteed, even if the original door was rated.
For architects, builders, developers, and facility managers, that means the real question isn’t “is this a smart lock?” — it’s “has this lock been tested as part of a door assembly that matches what I’m installing?”
Onetouch has documented fire-resistance testing for select digital door lock models — Onetouch OT500, Onetouch OT630, and Onetouch OT630 PRO — as part of a tested door assembly, achieving 120 minutes of Integrity (E) and 20 minutes of Insulation (I) under BS 476-20:1987 and BS 476-22:1987.
Why Fire-Rated Door Lock Solutions Matter
Fire Safety
Evaluated as part of the complete door assembly’s fire performance, not as a standalone claim.
Advanced Security
Controlled, authenticated access built on modern digital locking technology.
Door Compatibility
Matched to the specific door type and construction it was tested with.
Commercial-Grade
Built for high-traffic, high-compliance environments — residential towers, commercial buildings, and mixed-use developments.
Access Control
Reliable, auditable entry for authorised occupants and staff.
Documented Performance
Test results and certification are available for review — not just claimed.

## Fire-Rated Lock vs. Fire Sensor Lock: Know the Difference
These two terms get used interchangeably in the market — they shouldn’t be. Confusing them is one of the most common (and costly) mistakes in fire-door specification.
FIRE RATED LOCK
A fire rated lock is locking hardware considered as part of a fire-rated door assembly where fire-performance testing and compatibility with the tested configuration are important.
✓ Fire-performance focused
✓ Tested door assembly
✓ Hardware compatibility matters
FIRE SENSOR LOCK
A fire sensor lock generally refers to a locking or access-control solution that incorporates a fire or smoke detection-related function, such as triggering an action when a fire-related signal is received.
✓ Detection / trigger focused
✓ Fire or smoke signal integration
✓ System functionality matters
A sensor tells you there’s a problem. A fire-rated lock is about how the assembly performs once there is one. A lock having a heat sensor doesn’t mean it has been tested for fire resistance — those are two different questions, and only one of them is relevant when a fire-rated door is being specified.
What Should You Verify Before Specifying a Digital Lock for a Fire-Rated Door?
Ask for the actual test report, not just a product claim.
The lock alone, or the lock as part of the specific door assembly you’re installing?
Lock, frame, hinges, and seals should match the tested configuration, in line with IS 3614 and NBC requirements.
This is set by code, project design, and the local fire authority — not by the product spec sheet alone.
Occupants need to get out safely even if there’s a power failure — ask how egress works when the electronics stop responding.
Test certificates and installation requirements should be ready to hand to your fire consultant or auditor, not just referenced.

FAQs
Fire Rated Digital Door Locks are digital locking solutions designed for use with fire-rated doors where the compatibility of the door, locking hardware and tested door configuration needs to be considered. Fire performance should be evaluated based on the applicable tested door assembly and project requirements.
Selected Onetouch Digital Door Locks have been included in a documented fire-resistance test assembly with a door. The tested Onetouch models include Onetouch OT500 RF, Onetouch OT500 BLE, Onetouch OT630 RF, Onetouch OT630 BLE, and OT630 PRO.
The tested door assembly achieved 120 minutes Integrity (E) and 20 minutes Insulation (I).
The result relates to the tested door assembly incorporating the Onetouch Digital Door Lock, not automatically to the standalone lock.
Yes, a digital door lock can be considered for a fire-rated door application, but the door type, hardware, installation and tested configuration must be checked for compatibility before specification.
A Fire Rated Lock refers to locking hardware used within a door configuration that has been evaluated for fire performance under a specified test configuration.
A Fire Sensor Lock generally refers to a locking or access-control solution that incorporates a fire/smoke detection or emergency-release function.
A fire sensor function does not by itself mean that the lock is fire rated.
Fire Rated Digital Door Locks are considered for applications where the door assembly has specific fire-performance requirements and the locking hardware needs to be compatible with the tested configuration.
A standard digital door lock should not automatically be assumed to be suitable for a fire-rated door.
The supplied test documentation identifies:
- BS 476-20:1987
- BS 476-22:1987
The test was conducted on a Door + Onetouch Digital Door Lock assembly.
BS 476-20:1987 provides general principles for determining the fire resistance of elements of construction.
BS 476-22:1987 provides methods for determining the fire resistance of non-loadbearing elements of construction, including relevant door and shutter assemblies.
IS 3614 is an Indian Standard associated with the specification of fire doors and doorsets. For a project, the applicable edition and requirements should be checked against the current project specification and applicable Indian regulations.
The National Building Code of India (NBC) provides requirements and guidance related to fire and life safety in buildings. The exact requirements applicable to a fire-rated door and its hardware depend on the building type, occupancy, fire strategy and applicable authority requirements.
Fire performance is evaluated for a specific configuration of components. The door, frame, hardware and other relevant components need to be considered together rather than assuming that one component alone provides the complete fire performance.
Share your door type, door dimensions, project requirements, access-control requirements and required fire performance with the Onetouch technical team so the appropriate configuration can be evaluated.
Contact Onetouch with your project requirements. The team can assist with evaluating the appropriate digital door lock solution and technical requirements.
