Hi there, have an SV8100 question.
I have a customer that we just installed 3 NEC Door phones for. We have 2 PGD adapters on site.

The customer has a regular digital MLT in the lobby. They want the receptionist to be able to dial an access code to activate a relay to unlock the door.

Reading through the hardware and features+specs manual, I can access a General Purpose Relay off of the CP00 or the PGD using a 51 key in 15-07. But the manuals are confusing, as it says General Purpose Relay will not allow the door-unlock feature of the PGD to work.

I'm sure people have done this before -- any tips? Worst case I'll install a door phone up in the LAN Room and just have the reception dial an access code to call the door phone and press recall to activate the relay.
