NS700 and user wants to trigger external bell

[brucetech]

how could the NS700 be used to trigger a relay ? We have a ring group that gets called when door button is pressed on the Panasonic door phone ( thru the DPH2 card ) , but they also want a existing 12v buzzer to ring .

You can get a unit to covert a slt ring voltage to dry contacts

I would change the 12 v ringer to a bedlam bell and put it on an slt port

solved got a old klaxon horn relay set , that accepts ringing voltage .
