Alarm Configuration
7.6.1. Monitor Input Level Settings
When the Monitor/Alarm Input feature is properly configured, the AFS-16 can trigger an
alarm and/or perform A/B switching operations when the signal at Pin 4 (Monitor Input)
on the Control Module AUX connector goes high or low. In set up this feature, you must
first use the Control Card Jumper to select the non-active (non-alarm) state, and then
use the Monitor/Alarm Input configuration menu to select the active/alarm state (the
signal level that will trigger an alarm) as described in the Sections that follow.
