This configuration is suitable only for
normally-closed (N/C) contacts. If
normally-open (N/O) contacts are used,
as is the case with most smoke
detectors, a short circuit on one zone
activates both zones connected in
parallel.

If you require N/O contacts when using
split EOL resistors, refer to Figure 12 and
Figure 13 on pages 57 and 58 for
information on how to connect N/O
