I noticed that part of the door strike plate is broken on one side and the
strike assembly is no longer properly attached to the metal plate screwed in
now, how exactly do I replace it?
there are 2 floors in the house, with 2 intercom units at the main door and
one unit on every floor. the intercoms for the 2 floors are separate. both
intercoms have a door release which operates the same door strike. there's
only 1 wire going into the strike.
the intercoms are model Aiphone C-ML.
in the garage all the wires from the intercoms go into this junction box and
they're all tied together in various configurations (it's a huge mess).
there are the 2 transformers for the Aiphone intercoms plus a third very
large unit from ATC-Frost. ATC-frost is a transformer company, but this is
not a standard transformer, I assume it also has a relay inside because the
door release wires are combined before going into the transformer, so one
release wire (pair) goes in the transformer and one wire (pair) goes to the
if I change the strike do I have to change the transformer too?
what should I look out for before buying a new strike? are the intercom's
"door release" signals standard?
