This setup allows for a common style of interlock, where 3 or 4 doors require interlocking as separate interlocks
with a common door. This would normally involve cross wiring between interlocks, but simply changing both
jumpers to position B allows an easy to connect 3 and 2 door combination interlock.
In the example, doors 1, 2 and 3 are interlocked, also door 3 is interlocked with door 4. However, doors 1 and 2
are not interlocked with door 4. All functions and indications are the same as the standard IG432. If the interlock
is breached, all 4 doors are considered as part of the problem. If there are only 3 doors in total, it is probably best
just to ignore door 1 and link D1 permanently to +ve to give the impression that the door is always closed. The
standard features; fire alarm, privacy and de-fog are all allowed in this mode. From a reliability point of view,
mode 1 operation is not permitted in this setup.
