    Has anyone used these sounders ? Bought one to try out. Doesn't seem to like hkc panels . Have used the delta bell plus with no probs on hkc but this one is stressful

    I think it needs resistors on the triggers.

    Finally got it. Had to put a 4k7 resistor between 12v + and the bell trigger to create a small voltage for the bell to see at the bell trigger input.
