Alarm Interface & Mode Indicator Connections
Dry contact alarm connections, located on
PCB 1, are available regardless of any
additional monitoring method used. The
available dry contact alarm outputs are
listed in Table 1-4 and shown in Figure
1-4. Each contact may be wired as
normally open or normally closed. The
contacts are labeled to indicate their state
with the system powered on without an
alarm present.
Mode indicator contacts are available on
P4 terminals 10 – 12. When powered on,
an open contact between COM and NO
indicates the system is operating in Night
mode and a closed contact indicates the
system is operating in Day mode.
An
open contact between COM and NC
indicates the system is operating in Day
mode and a closed contact indicates the
system is operating in Night mode. The
mode
indicator contacts do not
differentiate between manual and
automatic operation as determined by the
Manual Mode Switch.
