I have been experiencing a number of problems with the DM02 modules (I have two installed).
The latest issue is that the Gate response does notwork. In the miscellaneous events I have added a response to pulse the gate (K1 on the second DM02 module). The response is very simple: Open Door 2 1 10
However, when a doorstation rings the phones, you never are given the option to open the gate??? (i.e., 4 to open gate). Further, when I execute the response from within Configurator, it causes the system to hang (or sometimes reset).
This is quite bizarre behavioi since it should simply close the relay, which would trigger the gate opening. I can figure out why I am not being given the option to open the gate in the first place, and if I execute the Pulse response it causes the system to hang.
My problem with DM02/DS01 is that when the button was pressed,the system became hung, all the three KP04 sound non-stop beep and LCD say 'Communication Failure Keypad #', and the phone keep ringing. When I pick up the phone I hear a buzzing sound, hang it up the phone keep ringing again. What is the possible cause?
OK, after several reset and *1 on the keypad to download text, the problem was gone. Now when the button was pressed, the phone ring and I can hear 'Door Station 1' but I cant talk to nor hear anything from the DS01.
This is 2 years old system, everything work properly except for this.
Check the Voice and MIC connections from DM02 to door station and correct and Voice/MIC to Comfort are correct and not mixed up
Also open a default file and write selective to select only the Configuration > Tuning Parameters so the correct tuning parameters are written to Comfort
See procedure in http://www.comfortforums.com/forum68/2679.html
Make sure you use the latest Comfigurator 3.4.0 or later so that the tuning paameters are the latest
