We are pleased to announce Lockey Digital door locks have been fire tested in accordance with BS EN 1634-1: 2014 & BS EN 1363-1: 2012
Lockey Digital has long supplied mechanical push-button fire door locks to UK specifiers, and independent testing under BS EN 1634-1:2014 formally certifies the performance characteristics that customers have relied on for years. The tests, conducted by UKAS-accredited laboratories, verify that the certified lock models maintain operational integrity under the standardised time-temperature curve replicating typical compartment fire development, preserving the rated fire resistance of the complete door assembly.
When used in conjunction with our customised intumescent kit, these locks can be installed on previously tested single or double leaf fire rated timber door sets to provide 30 or 60 minute integrity performance, without detracting from the overall performance of the digital door set.
Locks tested: 2430, 2435, 2435K, 2430DS, 2835 & 7055 (latch models)
What BS EN 1634-1:2014 Testing Involves
BS EN 1634-1:2014 is the European standard governing fire resistance testing for door and shutter assemblies. The test exposes the complete door assembly, including the locking hardware, to a controlled furnace environment that replicates the temperature progression of a developing compartment fire. Hot-face temperatures reach approximately 842°C at 30 minutes and 945°C at 60 minutes, matching the standard time-temperature curve defined in BS EN 1363-1:2012.
Assessment criteria measure integrity failure, which occurs when flames or hot gases penetrate the assembly, and insulation performance where applicable. Pass criteria require the door assembly to maintain its designated rating throughout the full test duration without excessive deflection, sustained flaming on the unexposed face, or gap formation that would allow flame propagation. Lockey’s certified latch models passed the 30-minute and 60-minute performance categories, making them suitable for FD30 and FD60 door set applications across commercial, residential, educational, and healthcare environments.
Why the Intumescent Kit Is Not Optional
The intumescent kit is not a supplementary accessory, it is a mandatory component of the certified installation. Intumescent graphite expands dramatically when heated, sealing the gaps that necessarily exist around the lock body, strike plate, and through-bolt mounting points. Without this expansion seal, hot gases and flames can bypass the lock assembly through the installation cutouts, invalidating the door’s fire rating regardless of the certified hardware used.
The Lockey intumescent kit ships with all necessary components cut to the correct profile for each certified lock model, along with installation templates and fitting instructions that preserve the tested configuration. For specifiers, building managers, and installers, following these instructions exactly is what converts a fire-rated door set from certified-on-paper to genuinely compliant when the fire test that matters actually occurs.
