5.8. External Alarm Inputs (Input Relays)

The controller can monitor any external device that uses a switch or relay to output status information. Connecting the external device to the input relay connections is the first step. The four external alarm inputs (also referred to as “Input Relay Alarms”) can be assigned a priority and routed or “mapped” to alarm output relays. Available assignments are “Ignore”, “Major”, “Minor”, and “Relay 1” ··· “Relay 6” (do not map relay to itself or the alarm will never clear). Screens for making the assignments are located at [SYSTEM/IN-RLY/RLY-MAP]. A user defined name or “alias” may also be assigned to each of these input alarms. Screens for making these assignments are located at [SYSTEM/IN-RLY/ALIAS]. For information on wiring connections to these inputs refer to Section 3.10.
