Dual locking
MiniTech can manage up to 2 locks, each with its own lock ID: 1, 2.

Dynamic codes
Dynamic Codes, also known as one-time codes or single use codes require additional equipment and PC software. Please contact us for more information.
Manager doesn’t open
The manager may have been prevented from being able to open the lock system, limited to managing the parameters of the lock system.
Manager management is disabled
The Master may have been prevented from managing the manager code, in which case MANAGER MANAGEMENT will be unavailable in the Master menu.
Motorbolt closure
Where a standard motorbolt is installed, the bolt will drive to close after automatically after 8 seconds as standard, or a time previously specified (Up to 500 seconds).

to close the bolt. See Lock reclosure mode
In some cases, the lock’s bolt may close automatically when the safe door is shut.

MiniTech Troubleshooting
LOCK PENALTY
An incorrect code has been entered 4 times. Wait for the penalty period of 4 minutes to elapse before entering a valid code.
If valid codes do not appear to be working, the keypad can be tested see Test the keypad
BATTERY LOW
The batteries must be replaced immediately. MiniTech is usually powered with a battery box mounted inside the safe or vault. Please consult the safe or vault supplier for more information on changing batteries. MiniTech can also be powered in an emergency using a 9v alkaline battery from the slot at the bottom of the keypad. Unscrew the security screw if fitted, pull the handle of the battery cover and connect the battery to the battery connector located inside the slot.
NO ANSWER
There is a connection fault between the keypad and the lock. Contact a safe engineer.
The display is not functioning
See BATTERY LOW, the batteries should be replaced.
A key does not beep when pressed
Undertake a keypad test (Special function 5) if any keys are faulty, contact a safe engineer.
The safe or vault door does not open
If the lock system is otherwise operating normally, there is a mechanical fault. Contact a safe engineer.
