5. 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-off-to-Unlock safety type(
Normally closed mode
);
set to 2-3 position for Power-on-to -Unlock type(
Normally open mode
).
• If different unlocking time is needed to be configured, change the
Unlock Timing
on
door station.(In debug state, press [1 #] --> [1] Installer Setup--> [2]Unlock Timing)
