• The "EG IN" (7) screw terminal can be used to connect a door opener, which can be placed
inside the room next to the door. You can also connect additional buttons for other door
openers in parallel. Pressing the button activates the relay for the same duration as when
you enter a user code. If you do not require this function, do not connect anything to the "EG
IN" screw terminal (7).

• Always connect the earth, as this prevents ESD (electrostatic discharge) that may cause the
code lock to malfunction.
• The diode should be connected as close as possible to the N.O. contacts. This prevents a
current from being generated in the N.O contact coil due to mutual induction, which may
damage the code lock.
• Check that the "DAP" jumper is in the "OFF" position.
• After making the necessary connections, attach the front plate to the plastic housing. Ensure
that the cables are not squashed, and check that they do not become detached from the
screw terminals.
• If necessary, use cable ties to fasten and organize the cables.
• Use the two mounting screws (1) to attach the front plate to the housing.
• Turn on the power supply. The coloured keypad backlight should turn on and the yellow LED
will flash slowly to indicate that the code lock is in standby mode.
