Matrix ETERNITY NE System Manual 559
Digital Output Port (DOP)
What's this?
The ETERNITY NE provides a Digital Output Port (DOP) for connecting a Door Lock release relay to be used in 
conjunction with the Door Phone connected to the system.
The Door Lock connected to the DOP can be opened by dialing the related Feature Command from the System 
Administrator mode.
ETERNITY NE remembers the state of DOP the during power failure. If a power failure occurs while the 
Door Lock device is being operated, the system will remember the last state (in this case, ON) and switch 
ON the DOP when power is restored.
