To prevent false alarms on unused alarm inputs, configure or connect (jumper) unused alarm inputs using one of the following options:
•Configure the alarm input as unsupervised and normally open on the Endura workstation. You do not have to connect the alarm input. This is the default.
•Configure the alarm input as unsupervised and normally closed on the Endura workstation. Then connect the alarm input directly to its ground. For example, connect pin 1 (Alarm 1) to pin 2 (Ground) if not using Alarm 1.
•Configure the alarm input as supervised and either normally open or normally closed. Then connect the alarm input directly to its ground through a
Figure 23 shows how to wire an alarm device to the Alarm 5 input (refer to Table D on page 23 for the specific connector pin assignments).
