Front Panel Controls
The SCC card has two buttons:
• CLR—clears the alarm history
The ALMC and ALMH indicators display the current and historical alarm severity, respectively.
Pressing this button clears the historical alarms. For example, if ALMC is yellow and ALMH is
red, the CLR button changes the ALMH indication from red to yellow.
• ACO—alarm cutoff
You can configure the MGX 8260 to report alarm conditions through contact closures that activate
audible or visual alarms. The ACO button stops these alarm indication by releasing the alarm
relays.
