sb0512 Posted December 12, 2007 Share Posted December 12, 2007 can you please confirm how to connect (Menvier SD1 speech dialler) trigger to Veritas 8 control panel When Trigger C (SD1) is connected to output B(Veritas 8) the SAB makes a repetitive low level noise. The installation suggests using a 1k resistor to tie Trigger c to prevnt the sounder attempting to activate. Is this correct? and should the 1k connect Trigger c to Ov (sounder connection terminals). Hope I have made the problem clear Link to comment Share on other sites More sharing options...
miaren Posted December 12, 2007 Share Posted December 12, 2007 Yes, link Output B on the Veritas (Bell -ve trigger) to Trigger C (-ve polarity trigger) on the SD1, so that when the bell operates the dialler starts. No, The 1K goes between 12v and Trigger C on the SD1. The idea is to hold the input C "high" until the panel sets the bell off (goes to Low) Good Luck Link to comment Share on other sites More sharing options...
