Digital Door Locks

3000 Series Combination Lock

Designed as an add-on for the Adams-Rite narrow-stile mortice latches for aluminium-framed glazed doors this unit has opened up a number of opportunities for combination locks denied to the other units because of their size. One disadvantage of the 3000 series lock is that for outward-opening doors there is nothing to hold onto to pull the door open meaning two hands are needed. Access is gained by entering the correct combination, which allows the outside thumbturn to open the door. From the inside, the thumbturn/handle will always retract the bolt allowing constant easy exit from the protected area. The cylinder key can be used to activate a holdback facility allowing the door to be left unlocked for ease of use (i.e. when carrying a large number of items through the door). The cylinder key can also be used to disable the combination altogether, allowing a manager to prevent access out of normal working hours.

Installation:
For narrow-stile aluminium-framed glazed doors the Adams-Rite latch and associated hardware are installed in the normal way. The 3000 assembly simply fits on the outside face of the door over the cylinder location. Timber doors require careful morticing and the correct set of accessories to suit the door thickness. Clean and lubricate the lock with WD40 or similar as ordinary oil attracts dirt and will eventually damage the lock.

Changing the combination
If a wrong combination is entered while operating the lock, turn the outside thumbturn to the left (anticlockwise) and release. This will clear any incorrectly pressed buttons then proceed to enter in the correct combination.

If your lock is opening on every turn of the knob or lever, but won’t open when entering a code, your lock may be in what we call a ZERO CODE. If this is the case, follow the procedure below for setting a new combination but miss out instruction 3.

Important: Perform this procedure with the DOOR OPEN. You should be able to enter the factory set code (or your old code if the factory set code has previously been changed) and retract the latch.

To change the combination, you will need the DF59 Control Key supplied with the lock & a small flat blade screwdriver.

Please read the following instructions at least once to ensure you understand the method before trying to change the combination.

When first purchased, most Simplex/Unican locks will be on a factory pre-set combination of 2 and 4 pressed at the same time, then 3 on it’s own.

1. It is necessary to use the DF59 Control Key provided with the lock to remove the lock assembly and trim plate. Insert the key into the keyway on the back of the lock and turn the key continuously to the left (anticlockwise) until the lock assembly can be removed and you can see the combination change slot.

2. Turn the outside thumbturn to the left (anticlockwise) as far as it will go and then release it. This is to ensure the lock has any previously used buttons cleared from its ‘memory’.

3. Enter your existing combination. Make sure you press each button firmly and release when you hear or feel it ‘click’.

4. Insert a screwdriver into combination change slot & turn screwdriver to the right (clockwise) to the stop position. You should feel a slight click. Turn the screwdriver back to the left (anticlockwise) to stop, and remove.

5. Turn the thumb piece to the left (anticlockwise) to the stop position and release. This is to clear out clear your old combination.

6. Choose a new combination, write it down. This combination can be as easy or as difficult as you wish. You can use just a single button as your code, however, this is not recommended as it would be easy for someone else to work out the combination and gain entry without your permission. Ideally, choose a code that uses both double button and single button presses. For instance, press 1 & 3 at the same time and release, then press 4 on its own. This code would be difficult for someone else to work out on their own but is easy for you to open as it takes only 2 actions to effect entry. With the door open, enter this new combination. Press each button fully and release it. You should feel a click each time you press a button telling you that the button was fully depressed.

7. Turn the external thumbturn to the right (clockwise) as far as it will go and this will set your new combination & retract the latch bolt. Release the thumbturn.

8. Replace the lock assembly and trim plate by inserting threaded rod portion into the combination change sleeve and turning to the right (clockwise) until trim plate is snug up against stile of door. The DF59 Control Key can be removed from the control lock assembly in a vertical or horizontal position only. With the door still open, try the lock again to make sure the code is working correctly.
