Fire to bell? Are you sure about that?
Would it not be more sensible to connect the bell to the bell connections (not pictured) and whatever fire alarm/button they have to the fire connection?
And I. The second pic the battery red appears to be connected to a non connected terminal (N/C)
correct in as the 1st pic does not show the right connections for bell. think the battery lead is in a "park" position. move to + when ready to power up.
if you look at the pic the terminals are Line Fault, 13v, 0v, Fire, Personal attack, intruder, Alarm set, alarm abort, alarm confirm....standard communicator outputs...not much used for a bell box...lol
