4. Door Lock Connections
1. Internal Power Supply Mode
Use the power of the system to supply for the electronic lock, so that the lock can be
connected to the door station directly, without an additional power supply for the electronic lock.
Note that the door station can only output 12Vdc power, therefore the kind of lock is limited.
• The rated power of the lock must be less than 12Vdc 300mA when using internal power
supply mode
• The GND must connect to the negative of the lock, and the COM connect to the positive .
• Jumper set to 1-2 position for Power-to-Unlock safety type(
Normally open mode
); set
to 2-3 position for Power-off-to -Unlock type(
Normally closed mode
).Note that the
unlock relay mode is set on the
Parameter
tab of DT CONFIG software.
• If different unlocking time is needed to be configured, the DT CONFIG software can be
used to change the
Unlock Timing
on the
Parameter
tab(see the program section).
