USER OPERATION
Up to 60 cards can be added to the lock. These cards can be assigned to the lock as either user cards,
Janitor Cards or Master Cards.

In Private Mode the lock is set to work with the same user cards(s). These cards needs to be previously
registered to this specific lock. In Private Mode up to 5 Master Cards and 55 User Cards can be added.
1: To open the lock, simply present your registered User Card and open the door. If the handle isn’t turned,
the lock will automatically re-lock after 4 seconds.
2: To close, simply turn the handle into locked position and the lock will automatically lock.
B. PUBLIC MODE
In Public Mode the lock is set to work with any Compatible Card that is presented to the lock. This will tem-
porarily register this card to the lock. Upon opening the lock with this card, the lock will remove this as the
Registered Card, and any other Compatible Card can now operate the lock. In Public Mode up to 5 Master
Cards and 50 Janitor Cards can be added.
1: To close, turn the handle into locked position and present a Compatible Card. This will lock the lock.
Other cards cannot now operate the lock.
2: To open, present your Registered Card to the lock. Any other card can now operate the lock.
MASTER CARD OPERATION
The Master Cards can open the lock in both modes. In Public Mode, opening with the Master Card, will also
erase any Registered Card from the lock and leave the lock in open position.
JANITOR CARD OPERATION
The Janitor Cards can open the lock in Public Mode. Different to the Master Card, the Janitor Card will not
erase the registered User Card. When opening with the Janitor Card the lock will automatically re-lock.
FACTORY RESET

Factory Mode, see lock setup for different options on how to reprogram the lock into desired configuration.
In Factory Modes the quick setup options are also available.

BASIC SETUP
When the lock is in Factory Mode (on delivery and after factory reset) and the battery is entered the
following options on how to deploy the lock is available.
A: QUICK SETUP OF MASTERCARD AND USER CARDS FOR USE IN PRIVATE MODE
First present a Compatible Card which will become a new Master Card. Then within 5 seconds present a
second card which will be registered as the first User Card. Continue to present cards within 5 seconds after
the previous registration to add additional User Cards. Then wait 5 seconds and the lock will go into Private
Mode. Further programming is then done by using the Programming Cards.
The sequence below describes an example of how to add one Master Card (1) and two User Cards (2 and 3). Up to
50 User Cards can be registered to each lock.

to be registred individually to the locks.
NOTE 2: The card needs to be cleared before beginning this procedure, see special commando 34.
On delivery, the card is cleared.
STEP 2A: Programming locks with the Copying Card into Public Mode
A lock in factory mode will read the setup on the Copying Card. This can be repeated for as many lock as
required.
The sequence below describes an example on how to use the Copying Card to set up lock in Public Mode.

lock, cannot close another lock before it has opened the first lock. As default double locking is allowed. The function of disal-
low cards to lock more than one lock is NOT available with Mifare DESfire-cards.
