You can use a normally-closed or normally-open contact. If the state of the
contact changes from the state you specify as normal, a signal is issued. You can
connect this contact to equipment at your facility (such as a light or an alarm bell)
to let you know when an alarm is active on the UPS. This feature is useful if the
UPS is located in a remote area where the UPS horn may not be heard
immediately.
NOTE: Do not operate the contacts in excess of 30 VAC (RMS) and 30 VDC at 5
A maximum.
