Sd1 Speech Dialler

[sb0512]

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

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

Many thanks for advice. My basic electronics knowledge (potential divider) rings a bell!!

Lets hope it dials out as well.
