Figure 71. Battery Setup - Digital Output (BDS-256)
The BDS has eight optional relay contact control outputs you can define to trigger on an
alarm event. After defining an Output Name and Trigger Name, the associated digital output
can change state on an alarm to control a user-selected device. If you select Latch, the output
latches. The relay is a Form C contact that de-energizes upon alarm condition reset.
Output Name - Type a name that describes the external device being controlled.
Trigger Name - From the drop-down list, select a parameter that energizes the
Control Output relay contact.
String # - The BDS Controller can have up to eight strings. In the String # box, select All or
the number that corresponds to the string number on System Setup|String.
Enable - Select Enable to energize a rear panel Control Output contact on a trigger event.
Latch - When selected, the Control Output contact energizes until manually reset. If not
selected, the Control Output de-energizes when the trigger event clears.
Note: For BDS setup, the system shows information based on string one only. If you have
more than one, they are defaulted from string one.
