will pulse the relay output for approximately ½ second. The relay output will
return to its normal state when all critical alarms have returned to normal.
Non-Critical Reflash Grouped output driven by any alarm selected as non-
critical. Upon a non-critical alarm, the relay output changes state. Every new
non-critical alarm will pulse the relay output for approximately ½ second. The
relay output will return to its normal state when all critical alarms have returned
to normal.
Critical Fault
is in the alarm state. The relay output will only return to its normal state when all
critical alarms have returned to normal. The relay output is not affected by the
silence or acknowledge pushbutton.
Non-Critical Fault
input is in the alarm state. The relay output will only return to its normal state
when all non-critical alarms have returned to normal. The relay output is not
affected by the silence or acknowledge pushbutton.
Power Fail This relay output will change state when the Power is lost. The relay
coil is energized upon start-up and the contacts will transfer upon a loss of
power.
Ground Fault
condition is detected. (Note: Must have Ground Fault Detector Option GF)
The ground fault can be either a positive ground (+FCV wire to ground) or a
negative ground (FCV return wire to ground).
Watchdog System healthy output. It will activate when the system is not
processing alarms, like during the configuration process or when there is a
system failure. The Watchdog will detect when there is a remote communication
failure, if Modbus or DNP are used. The communication failure would activate
after a period of inactivity, including a disconnected or broken cable.
The Configuration Screen will show a summary of the Common Relay functions
to the right. To select a relay to edit use the up or down arrows beside the relay
number or click on the entry in the summary.
Note: In addition to these configurations, the repeat relay contact may be
selected as a Form A or (Normally Open) or Form B (Normally Closed) using the
I/O jumpers described in the previous section.
Common Functions
A number of system-wide functions are available through the Common Service
Module. To select a function click on the white box to the right of the name so as
a tick mark appears. To turn the function off click on the box again so as the tick
is removed. The available functions are:-
Enable Internal Horn (Option HN)
When selected, this will activate the internal audible device upon any non-critical

This relay output will change state when any critical input
This relay output will change state when any non-critical
This relay output will change state when a ground fault
