In this small how-to we want to document how to implement a VoIP/SIP doorkeeper using the Snom PA1.


Audio Connections

  1. Connect Line OUT to the Door Phone Speaker
  2. Connect MIC IN to the Door Phone Receiver


Keyboard Connections

  1. Key 6 and 7 control Dial Pad Key 1, see also PA-1 Keyboard Matrix
  2. Connect Key 6 and 7 to the Door Phone Call Button
  3. From the PA-1 Web User Interface, configure a Speed Dial to an internal Extension and assign it to Dial Pad Key 1
  4. Alternatively, you can use any combination of keys or single Dial Pad Key:

 


 Dial Pad Key   PIN  PIN
0 2 3
1 6
2
3
4

6 1
7 6
8 5
9 7 0


Electronic Door Strike Relay


Use I/O Connector 1 or 2 to supply voltage to an Electronic Door Strike.


I/O Connector 1

 



I/O Connector 2


Pins 1, 2, 3 and 4 are Normally Open contacts. They can be closed, supplying 3.3vdc, by using remote DTMF or the Web Interface. 


PIN 1: On 1#, Off 1*

PIN 2: On 2#, Off 2*

PIN 3: On 3#, Off 3*

PIN 4: On 4#, Off 4*


With the wiring harness connected to the I/O 2 port of the PA 1;


Black = Ground

Brown = 12v

Yellow = Pin 3

Purple = Pin 4
