Alarm Wiring
Alarms are asserted when the controller detects a system alarm or a program alarm.
Each MP Module supports the following redundant alarm contacts:
Set 1
• Normally closed (NC) contact
• Common (C)
Set 2
• Normally closed (NC) contact
• Common (C)
A control engineer should specify the actual use of these contacts. Typically, alarm
wiring is connected to a local or remote annunciator. These devices can be wired
in parallel with the alarm wiring so that the designated alarm goes off when either
contact signals an alarm condition. For more information on program alarms, see
the
TriStation 1131 Developer's Guide.
