Lockey digital door locks ref 2430, 2435, 2435K, 2430DS, 2835 & 7055 have been tested/assessed in conjunction with Lockey intumescent kits to BS EN 1634-1: 2014 or BS 476: part 22 and BS EN 1363-1: 2012 for installation on 30 & 60 minute fire rated timber door sets.
The tests were carried out by Exova Warrington Fire which concluded that 
when installed with the intumescent kit provided by Lockey and should the recommendations given in assessment report 375139 be followed, it can be concluded that Lockey Digital Door Locks as detailed within the report may be fitted to previously tested or assessed single or double leaf fire rated timber door sets, without detracting from the overall performance of the door set.
Lockey intumescent kits have been customised from 1mm self adhesive graphite for ease of installation, and include templates & fitting instructions to ensure installation is carried out as per the test/assessment requirements.

About the Exova Warrington Fire Assessment
Exova Warrington Fire, now operating as Element Materials Technology, is one of the UK’s longest-established fire testing laboratories and a UKAS-accredited body for fire resistance assessment under BS EN 1634-1:2014. Their assessment report 375139 represents the formal technical evidence underpinning the fire performance claims for the Lockey certified range, making it directly referenceable in specification documents, compliance submissions, and fire risk assessments prepared by Responsible Persons under the Regulatory Reform (Fire Safety) Order 2005. For UK specifiers working within the tightened regulatory framework introduced by the Building Safety Act 2022, having named laboratory evidence tied to specific hardware models simplifies the process of demonstrating that the chosen lock forms part of a compliant door assembly rather than creating an untested substitution.
Where Fire-Rated Hardware Matters Most
Our full range of fire door locks is specified across a wide variety of building types including hospitals, care homes, schools, HMOs, hotels, offices, and high-rise residential blocks. In each of these environments, fire doors perform a dual function: providing routine access control and security under normal conditions while serving as passive fire protection during emergencies. The lock selected must satisfy both functions simultaneously, which is precisely why the intumescent kit matters. Without it, the mechanical performance may be sound, but the fire-rated integrity of the assembly is compromised.
For a complete overview of the regulatory framework, performance classifications, installation principles, and maintenance requirements governing fire-rated door locks in commercial and institutional buildings, our dedicated guide covers the full specification journey from risk assessment through to certified installation. Whether you’re a facilities manager tasked with remediating an existing building’s fire door provisions or a specifier working on new-build projects, understanding how the certified hardware, the intumescent kit, and the tested door set interact is essential to delivering genuinely compliant installations.
