Multiple Smoke Control Station
See NCA-2 Manual for instructions on programming the following example.
ZL498 = OR(SCSDIS(A25),N2ZL498)
ZL499 = OR(AUTO(A25))
ZL500 = AND(NOT(SCSDIS(A25)),NOT(N2ZL500))
ZL501 = AND(ZL499,N2ZL499)

Indicators
Primary SCS ZL498 will be active when the primary's
Disabled enable/disable switch is disabled and the secondary
NCA-2 SCS is enabled/disabled.
-- Required for Multiple Smoke Control Systems
applications; monitors the Auto status of the SCS-
8L (designated as A25 in this example).
Logic zone address must be lower than that of the
MSCS Control Zone.
Primary SCS ZL500 identifies the MSCS Control Zone of the
Active primary NCA-2. This logic zone will be active when
the primary's enable/disable switch (SCSDIS) is
enabled and the secondary NCA-2 is disabled.
-- Required to track when the SCS-8L is in Auto. SCS-
8L must use the next consecutive logic zone
address after the MSCS Control Zone of the primary
NCA-2.
Secondary SCS N2ZL500 identifies the MSCS Control Zone of the
Active secondary NCA-2.
