The TwinPad electronic furniture lock offers you the option of
using the lock with code entry as well as with an RFID transpon-
der solution (card, chip, wristband).
Due to the versatile application possibilities, the locking system
is used in hotels, fitness studios, educational institutions, offices
and workshops, among others. Thanks to the flexible installation
options, the lock can be installed in both wooden and metal
cabinets.
Important: Please observe all warnings and read through
the entire operating instructions before you begin with
the configuration.

1 The lock is approved for VARTA brand batteries. The use of other
batteries may result in a reduced number of possible locking cycles.

Mode: Multi User Authorization (Multi User Mode)
This mode is suitable for constantly changing users who only
use the compartment temporarily or once, e.g. in a sports
facility. Codes or transponder media are valid for a single locking
process and are deleted by the lock when the compartment is
reopened so that a new code or transponder medium can be
used. The locking bolt remains open until a new code or trans-
ponder medium locks the lock again.
User code: Before locking, the door must be closed (slightly
pressed). The user enters a user code of choice (4 to 8 digits) to
lock and confirms the entry with the hook key. The green LED
starts flashing. The lock is opened by entering the same code.
Transponder: Before locking, the door must be closed (slightly
pressed). To lock the lock, the user holds the transponder me-
dium centrally in front of the lock. The green LED starts flashing.
The lock can then be only opened with the same transponder
medium.
Master Code
The Master Code can unlock the lock independently of the set
mode (emergency opening). In Multi User Mode, the user code
used for locking is deleted after the Master Code is entered.
In Private Mode, the user code is reset to the default setting
(1234).
Note: We recommend programming a private Master Code
before putting the lock into operation.
Master Card
The Master Card can open the lock independently of the set
mode (emergency opening). In Multi User Mode, the transpon-
der medium used for locking is deleted from the lock.
Automatic locking (Private Mode)
The lock locks automatically after five seconds after unlocking.
The door does not have to be closed for this. The latch function
allows the door to be closed by pressing slightly even with the
lock locked.
LED locking indication
If the lock is locked, the green LED flashes briefly at regular
intervals.
Block mode
After four consecutive failed opening attempts, the lock locks
for 60 seconds. During this period, no action is possible on the
lock. The lock can be opened with an RFID transponder. For use
with codes, the block mode remains active until the end of the
60 seconds.
Signal tones
Signal tones sound during the opening and closing process as
well as during configuration steps. The volume of these signal
tones can be set with the LOUD, SILENT or OFF function cards.
Battery Warning
If the battery voltage falls below a certain level, a short sig-
nal tone sounds during operation. If the voltage falls into the
critical range, three beeps sound and the lock can no longer be
operated.

Mode: Fixed Assigned Authorization (Private Mode)
In this mode, a user code or a transponder medium is pre-set
with which the lock can be operated. This mode is suitable for
user groups where user rights do not have to change perman-
ently, e.g. in an office cabinet.
User code: To lock the lock, the user enters a previously stored
user code and confirms the entry with the hook key. The lock is
unlocked by entering a stored user code. The locking bolt locks
automatically after 5 seconds. A code that has not been stored
is rejected by the lock.
Transponder: To unlock the lock, the user holds a stored trans-
ponder medium centrally in front of the lock. The locking bolt
locks automatically after 5 seconds. Non-stored transponder
media are rejected by the lock.

Assembly Instructions
1Drill all holes required for installation according to the
dimensioned product drawing.
2Carefully place the front unit on the front of the cabinet
and carefully pass the connecting cable through the
appropriate hole (optimal diameter 18mm).
3If batteries are already installed, open the battery compart-
ment and remove the 4 AA batteries from the back unit.
4Take the back unit and connect the connecting cable:
Carefully slide the cable into the socket on the back
of the back unit. Make sure that the two small guide
rails are visible.
5Make sure that the ribbon cable is not pinched during
installation.This can cause permanent damage to the
cable, which prevents error-free operation. An incorrect
installation will void the manufacturer‘s warranty.
6Important note: The M4x29.5 screws included in the scope
of delivery have been developed for the use of doors and
drawers with a material thickness of minimum 17 mm and
maximum 30 mm . Mounting on fronts that are thinner
requires shorter M4-screws (formula: material thickness +
13mm). If you then use the existing screws, the touchpad
can be permanently damaged.
Insert the 2 threaded screws (M4x29.5) through the
corresponding holes and screw the back unit to the
touchpad. For mounting on fronts thinner than 2.8mm,
e.g. steel doors, the use of a wooden / HPL adapter plate
or corresponding washers might be useful to compensate
for the distance between touchpad and back unit. These
washers (not included) should have an inside diameter of
at least 6.8mm. After the touchpad has been plugged
in, the washers are plugged from the inside onto the two
lugs (with the M4 internal thread) before the back unit is
screwed on. Failure to follow this instruction will void the
manufacturer‘s warranty.
7Place the spring-loaded strike plate on the inside of the
cabinet and fix it with the 3 wood screws (3.4x20).
8Insert the four AA batteries and close the battery case.
Fix the housing cover with the appropriate screw (3x8).
9At the beginning, make sure the battery cover is closed.
Never close the cabinet door with the battery cover on the
lock open. Closing the cabinet door may cause batteries to
come loose. Test whether the door can be closed without
problems and whether the lock closes smoothly. If not,
please adjust the lock and striking plate so that the lock
can close without pressure or friction. Start setting up the
locking system according to the instructions (programming
code and RFID).

Disposal and Battery NoteEmergency Power Supply
If the batteries do not have enough voltage, an external power
supply can be connected via the micro USB port.
For this, the touchpad has to be connected to a power supply,
notebook or power bank via micro USB cable. The lock can then
be operated again.
Note: We recommend to replace the batteries immediately.
Image rights: cover, wood texture, Maksym Chornii / 123rf
If the lock indicates a low battery level, the battery should be
changed immediately.
Note: The lock is approved for VARTA brand batteries. The use
of other batteries may result in a reduced number of possible
locking cycles.
1. Loosen the screw of the battery compartment cover
and remove the cover.
2. Remove empty batteries and insert new batteries
according to the symbols (+ / -).
3. Close the battery compartment with the cover
and fix it with the screw.
EU Directive 2012/19/EU regulates the proper take-back, treat-
ment and recycling of used electronic equipment.
Every consumer is required by law to dispose of batteries,
accumulators or electrical and electronic equipment („waste
equipment“) powered by batteries or accumulators separatly
from household waste, as they contain harmful substances
and valuable resources. Disposal can be done at a collection or
take-back point approved for this purpose, e.g. a local recycling
center. Waste equipment, batteries or rechargeable batteries are
accepted there free of charge and recycled in an environmentally
friendly and resource-saving manner.
Waste equipment, used batteries or rechargeable batteries can
also be returned to us. The return must be sufficiently stamped to
the address below.
The following symbol on the waste electrical equipment, batte-
ries or accumulators indicates that they must not be disposed of
with household waste:
Caution when using batteries!
The battery may explode or release flammable gases if it is mis-
handled, destroyed, or the wrong type of battery is used. Do not
recharge the battery, disassemble it, expose it to extremely high
temperatures or throw it into a fire.
On batteries containing harmful substances, you will find indica-
tions in the form of abbreviations for the ingredients cadmium
(Cd), mercury (Hg) and lead (Pb) in each case.
