Frequently Asked Questions
What is the DDA lever and what makes it different from a standard lever?
The BL5401 uses a flat bar lever compliant with BCA AS1428.1-2009 (Design for Access and Mobility). This lever requires significantly less grip force and torque than a round bar lever, making it suitable for users with limited hand strength or dexterity. It is the correct lever type for disability access doors, accessible toilet facilities, and any application where BCA accessibility compliance is required for the locking hardware. Lever compliance relates to the handle design only and does not imply full building access compliance for the installation.
How do I change the PIN code?
The code must be changed with the lock removed from the door. Remove the 4 red screws, carefully lift the cover plate (springs are attached), hold the C tumbler depressed at all times, then use the supplied tweezers to reposition the red (coded) and blue (uncoded) tumblers. All square cut-outs must face outward and coloured marks must face upward. Replace the cover plate and test the new code before reinstalling. Codes are non-sequential — 1234 can be entered in any order.
How does the free passage function work?
Enter the correct code, rotate the lever, then press F while the lever is still rotating. The lever becomes free-turning. To exit free passage: rotate the lever and press C until an audible click is heard. The free passage function can be permanently deactivated by inserting the supplied plug behind the F button slot on the back of the keypad before installation.
Can I reverse the handing on site?
Yes. All BL5401 units are factory set for right-hand doors. To change: remove the rubber grommet at the base of the keypad handle, use the included hex wrench to remove the grub screw, rotate the handle 180° and refit. Repeat for the inside handle. Handing is determined from the outside of the door: right hand = hinges on the right; left hand = hinges on the left, regardless of swing direction.
Is the BL5401 compatible with third-party lock cases?
Yes. The BL5401 uses an 8mm square drive spindle which is compatible with most leading brands of tubular latch and mortice lock case. Always confirm spindle compatibility with the lock case manufacturer before specifying in a multi-brand installation.
All Borg locks are warranted against mechanical defects in materials and workmanship under normal use and service for a minimum of 12 months from date of sale. The warranty does not cover damage arising from misuse, vandalism, or improper installation. The lock must not be dismantled — doing so will invalidate the warranty.
