Configuring the terminal | 74
Configuring the external alarms
Each terminal has two external alarm inputs and four external alarm outputs, terminated on the
ALARM RJ-45 connector on the terminal front panel.
Each external alarm input can activate the Major / Minor terminal alarm or be mapped to a remote
terminal external alarm output.
The ‘Alarm On When’ (active alarm state) for both inputs can be configured for 'External Source On' or
'External Source Off' (default is External Source On).
Each external alarm output can be triggered by a local terminal Major / Minor alarm or a remote
terminal Major / Minor alarm or either of the remote external alarm inputs.
The ‘Relay Closed When’ for the four outputs can be configured for 'Alarm On' or 'Alarm Off' (default is
Alarm Off).
Configuring the external alarm inputs
To configure the External Alarm Inputs:
Select Link or Local or Remote > Alarms > Ext Alarm Inputs
Note: When the terminal MHSB mode is enabled, the external alarm input 2 is used by the protection
switch system so is not available for user alarms.
The state of the local terminal external alarm input is always sent to the remote terminal and the
external alarm input can be mapped to a remote terminal external alarm output.
Alarms present on a local terminal external alarm input will only be displayed in the remote terminal
Alarm Table / Alarm History if it has been mapped to one of the remote terminal external alarm
outputs.
