Not too familiar with this particular type but there will be permanent power ( 12volts from / to + - ) and a connection to make the autodialler start usually a switched - . This can be either connected to bell output on panel or to digi ch3 / intruder output if you have one . Depending on the autodialler you can use other channels for fire , PA , medical etc if you have appropriate outputs on panel . There may also be a tamper connection on auto dialler that connect in usual method to your panel
Hope that helps
