Customer Alarm Interface/Remote Source Select
The Customer Alarm Interface Definitions Screen is used to program the customer alarm names
and actions. Each customer alarm can be programmed to latch (requiring manual reset), to be
included in the summary alarms, to freeze the history status buffer, and/or to activate the auto-
dial. Each customer alarm can also be programmed with a delay on activation of 0 to 999.9 sec-
onds.
To limit access to authorized personnel, security access is required to make changes. The cus-
tomer alarm inputs are dry contacts connected to the optional customer alarm interface board.
Refer to 1.2.4 - Control Wiring Connections.
Customer Alarms #1 and #2 can be used for remote preferred source selection. The customer
alarm interface and remote preferred source options are activated using the system options selec-
tion on the system configuration screen. With the remote preferred source option activated, clos-
ing the customer Alarm #1 Input selects Source 2 as preferred. Closing customer Alarm #2 Input
selects source 1 as preferred. With neither or both Alarm #1 and Alarm #2 inputs closed, the
remote preferred source selection is ignored, and the current STS preferred source is retained.
The remote preferred source selection is also ignored while the unit source transfer screen is acti-
vated to allow local override of the remote source selection.
