External Alarm Relay Monitor Connection
This connection alerts the user when a selected external alarm condition exists. This connection could be
used to monitor a UPS with dry contacts or another ATLAS 550. The 2-pin, removable terminal block
connects with external wiring. Refer to DLP-14,
Connecting the Alarm Contacts
, for detailed instructions.
Clear the alarm condition by pressing the
ACO
switch located on the front panel of the ATLAS 550.
Table 6 shows the pinout for the External Alarm Relay connector.
