6. ATLAS 890 FRONT PANEL

The front panel contains the Alarm Cut-off (ACO) switch, the CRAFT port, and the controller and option

modules, and system (fans and alarm) status

LEDS. The LEDs provide visual information about the

ATLAS 890 base unit and any option module that may be installed. Figure 3 identifies these features.

ACO Switch

The ACO switch deactivates (clears) the Alarm Relay, located on the rear panel, after an alarm condition

has occurred. If an alarm condition is corrected and then reoccurs, the Alarm Relay activates again.
