IMPORTANT
Do not use the following wiring methods. They will cause the system
to malfunction:
Do not parallel sub station wires
between TC-M master stations.
Wiring from TB-SE must be
homerun to EACH master station.
Door adaptor TB-AD1(10) can only
be wired to one master. Doors
cannot call both master stations.
