When using two D192C or D192G modules for audible silence the system will not trigger relay B when a fire alarm is activated.
The point index for point 3 and relay B in Relay Parameters has not been programmed correctly.
Ensure the D136 is plugged in the ALT. Bell Socket 3 pins up, 2 pins down.
You will need to edit the point index that is assigned to point 3 for relay “A” and relay parameters for relay “B”.
