External Alarms

The external alarms are used to monitor the status of one or more external devices
via the Node G. A UPS or entry alarm is among the items that might be connected to
the contact relay and monitored via the Node G. The cage clamp connectors are
located on the EAC-card.
Observe that the cross-sectional area of the wires to be connected must be in the
range from 0.5 - 1.0 mm

All external alarms are defaulted to high (5 VDC) without connection. This setting
may be changed on the external alarm page to active high or active low. The severity
levels of the external alarms may be set via the web page. More information about
the external alarm settings is available in the web page and online-help.
Make sure that external alarms which are not required are set to active low or disable
them; otherwise the status will always show an alarm.
The names for each external alarm are user-definable on the external alarm page;
renaming them to indicate the use of these alarms is recommendable.
