We are integrating a doorking 1812 new unit to a control4 system. The gate company did not even connect it to the phone system, so we have to do that also. We have never done it. It looks simple - connect the incoming phone line from the street to one side, the house line to the other side, and the doorking unit it the middle. They have an analog panasonic t824 phone system.

- does any programing have to be done on the panasonic side, or is it all doorking?
- is there a way to tap into the doorking phone unit to connect to control4, or do we have to have a wire from the doorking relay to the HC800 relay input?

Thanks.

I have a little experience with these. Yes, connect phone as you described. Programming is via doorking for codes and options. The manual is pretty detailed. As for integrating with C4, yep, you have to use a relay. There are a couple of places you can connect it. One of them allows latching. Hold relay closed and the gate stays open indefinitely or until someone closes it via the phone or 1812 keypad. Open relay and the gate closes after its normal programmed delay. Close the relay momentarily and the gate opens and then closes after normal delay.

I believe we used a pair on the same cat5 that was already run for phone. Has been working fine for almost a year.

I would recommend putting the 1812 into intercom mode and using an unused CO on the 824. Set it for a different ring chime.

Takes the phone line out of the equation. Especially if they are still using the analog phone line!

Agree, just plug the 1812 phone output into unused CO input on the phone system and change 1812 programming to Intercom mode.

Why take the phone line out of the equation? What is the benefit?

Turn your question around.  What is the benefit of tying up a CO just for the Doorking if you don't need to?

Doorking has the intercom mode so you don't have to tie up or dedicate a CO (phone line) to the 1812.  The phone system still sees it as an incoming line.  Read the manual to learn the codes for operating the 1812 from a system phone.  Program system phone DSS buttons for hold open, timed open, close, etc.  Much easier to do this with the 1812 in intercom mode.

If you didn't have the phone system then you'd need to loop a CO through the 1812 as you mention in your first post.  But since you have the Pany 824, intercom mode is the way to go.

Ok so we don't need the bypass module. We just wire to line 3 on the T824. The doorking provides the dc current for voice.

Yes. Putting the 1812 into intercom mode will cause it to generate the 48vdc and act as a phone line into the CO input on the 824.

2.3.3 Phone / Intercom Mode
The 1812 is normally connected in series with a residents incoming phone line, which supplies a constant source of DC voltage. When the 1812 is connected in this manner, program the unit for PHONE mode. If the 1812 is to be connected to an open C.O. (Central Office) port on a key type telephone system, or if the 1812 is connected directly to another telephone without a C.O. line, program the unit for INTERCOM mode. When programmed in intercom mode, the 1812 will supply the constant DC voltage necessary for operation and will disconnect the PHIN terminals from the circuit since these are not used in intercom mode.

I would still wire thru the "bypass" module.
If something goes haywire in the 1812, they can easily stop the phones from phantom ringing.

Can't they also just pull line 3 from the t824?

How would you use the bypass module when in intercom mode?

When connecting 2 1812 access plus units together, do you need to connect to both lan ports, or just the first one?

programmed the 1812 today and all went well.

- Is there a way to tap into the button press on the unit so we can integrate it into a control4 system so that upon button press we can program events?

Done. Yellow and white wires from 1812 button connected to hc800 contact input.

Two years later....

The client wants to add a panasonic cordless to the phone system. The cordless has lines 1 and 2 only. The client has line 1 as the main line and line 2 as the fax line. The gate is on co3 in intercom mode on the panasonic system. Am I correct that the cordless will not be able to answer the gate because it only has two lines and the system is in intercom mode and the gate line is in effect "line 3"?

Thanks!

Presuming this is a "non" system cordless?
Program that extension to ring from all three lines

Only line one connects to the system. Yet all 3 can be accessed.
