This article takes you through the general wiring principles of a door lock with TID-600R. 

Configuring and Connecting Door Locks

To configure and connect the door locks:

1. Select the lock type between N.O. (Normally Open / Fail Secure) and N.C. (Normally Closed / Fail Safe) for the Alarm output 2, and set the duration under the Alarm output setting.
   
   
   
   

   NOTE: If 12VDC power is directly connected to the intercom, it is recommended 
   to use at least 2A power supply to provide 550mA out of the intercom.
   

   The diagram below is for a Normally Open setup.
   
   
   
   The diagram below is for a Normally Closed door lock.
   
   
   
   
2. If you are dealing with an N.O. lock that requires more than 550mA, connect a power supply with a higher amperage to the intercom as below.
   
   
   
   This is the Normally Closed diagram.
