This point indicates whether any Silence Alarms keyswitches
are active. The status of this point is determined by output logic
in the system logic page. When the equation for ESA (External
Silence Alarms) is true, this point indicates both ActiveInput and
Fault. The default equation for ESA includes the local Silence
Alarms keyswitch on the MX1 front panel and the Silence
Alarms keyswitches on any connected RZDUs. NZS 4512
requires a defect be signalled when any Silence Alarms
keyswitch is active, which is why this point is assigned a status
of fault (as well as ActiveInput) when the equation for ESA is
true. The operation of Alarm Devices outputs are inhibited when
Silence Alarms is true, though this will not prevent Trial Evac
from operating the Alarm Devices.
This point indicates whether any Trial Evac keyswitches are
active. The status of this point is determined by output logic in
the system logic page. When the equation for TEV is true, this
point indicates a status of ActiveInput. The default equation for
TEV includes the local Trial Evac keyswitch on the MX1 front
panel and the Trial Evac keyswitches on any connected
RZDUs.
This point indicates whether any Services Restore keyswitches
are active. The status of this point is determined by output logic
in the system logic page. When the equation for BSR (Building
Services Restore) is true, this point indicates a status of
ActiveInput. The default equation for BSR includes the local
Services Restore keyswitch on the MX1 front panel and the
Services Restore keyswitches on any connected RZDUs.
This point will be set to Fault when there are zones
automatically disabled due to the zones being in alarm at the
time of a silence alarms keyswitch restoration to normal,
otherwise the state is Normal.
Provides the common status of the routing outputs. The status
will show Alarm when the Alarm routing output should be
activated, ActInput when the Fault or Disables routing outputs
should be activated. It will become disabled when all of the
Alarm, Fault and Disables routing points are disabled. It cannot
be enabled until at least one of those points becomes enabled.
Provides the alarm routing status. The status will show ActInput
when the alarm routing output should be activated, Fault if an
Alarm Routing Fault is present, Disable if the Alarm Routing is
disabled (in which case the Alarm Routing output is not
activated when this point has an ActInput status.)
Provides the fault routing status. The status will show Active
Input when the fault routing output should be activated, Fault if
a Fault Routing Fault is present, Disable if the Fault Routing is
disabled (in which case the Fault Routing output is not activated
when this point has an Active Input status.)
Provides the disables routing status. The status will show
ActInput when the disables routing output should be activated,
Fault if a Disables Routing Fault is present, Disable if the
Disables Routing is disabled (in which case the Disables
Routing output is not activated when this point has an ActInput
status.)
Ancillary
Disables,
Ancil Group 0
The disable status of this point may be used to control the
operation of site-specific ancillary functions.
Ancillary
Disables,
Ancil Group 1
The disable status of this point may be used to control the
