Lock Output Jumper Settings
There are two jumpers, one for each lock output, LK1 and LK2.
Each output provides 750mA at 12VDC
Default setting:
The lock output will be at 0Vdc in
normal state and toggles to
12Vdc during the unlock time.
(De-energize lock output)
The lock output will be at 12Vdc in
normal state and toggles to 0Vdc during
the unlock time. This is the typical
setting for electromagnetic door lock.
(Energize lock output)

The output is at 12 VDC to keep
the door locked and toggles to 0V
during the unlock time.
Each lock output provides 750mA at 12VDC. When a dierent voltage or more current is required,
refer to the diagram below on how to connect an external power supply.
Use the A22K on-board dry contact relay, one per
door, for external power supply connection. By
default the on-board relay follow the unlock time.
