External Alarm Input Connections

Four user-defined alarm inputs are provided on connector J3. Each alarm input can be

individually programmed for alarm priority (MAJOR or MINOR) and input contact configuration

(Normally Open or Normally Closed). Each alarm input utilizes a two wire connection, with one

side of the contact attached to user input pin and the other side connected to one of the –BAT

pins. The input alarm contacts must be isolated (“dry”).

The factory default settings for these alarms are MAJOR alarm priority and a Normally Open

(NO) contact input, closed for alarm. Changing the contact input to Normally Closed or

programming an alarm condition for MINOR requires a change to dipswitch S1 mounted on the

system Controller Board. See application details in Section 5.

A cable (0W09051) is available to connect the input alarms. Refer to Figure 3.7-2 for rear

panel connections.
