Screw terminals 1 + 2 (“12V DC”): Connection for the power supply
These two terminals are to be connected to the operating voltage 12 V/DC. Pay attention to
the correct polarity; screw terminal 1 = plus/+, screw terminal 2 = minus/-/GND. Depending on
the devices connected to the code lock (e.g. door opener), ensure correspondingly sufficient
power supply.
Screw terminals 3 + 4 (“DOOR LOCK”): Output #1 for door opener
A door opener can be connected directly to this output; the code lock
delivers 12 V/DC and up to 3 A.
Pay attention to the correct polarity depending on the door opener;
screw terminal 3 = plus/+, screw terminal 4 = minus/-/GND.
The protective diode must be connected near to the door
opener with correct polarity.
The output can either operate in toggle mode (each code entry toggles
the output) or be activated for a specific time (1 - 99999 seconds).
The output is pre-configured for a “fail-securee” door opener, as is
usual for a front door. If necessary, this can be changed via the jumper
“
DOOR LOCK
” (
J
).
•
“Fail-Secure” door openers:
Releases the locking latch only when its operating voltage is applied
(common design for front doors).
•
“Fail-Safe” door openers:
Releases the locking latch only when the operating voltage is absent
(rare type, used, for example, for escape route doors, as the door
can be opened in the event of a power failure).
Screw terminal 5 (“DATA I/O”):
This terminal serves as communication port. It is only needed if several devices (code locks,
RFID readers, alarm systems) are to be operated together. In this case, it is used for data
exchange between the devices. Terminal “
DATA I/O
” must then be connected to all devices.
