REVIEWING THE FRONT PANEL DESIGN

The front panel contains the Alarm Cut-off switch (
system controller, the network modules, and the option modules. Figure 1 identifies the
port, and the LEDs.

ACO Switch

Pressing the switch deactivates (clears) the Alarm Relay, located on the back panel of the
ACO
ATLAS 550, after an alarm condition has occurred. If an alarm condition is corrected and then reoccurs,
the Alarm Relay re-energizes.

CRAFT Port (DB-9, female)

Use the port to configure the system via an EIA-232 connection. Table 1 on page 28 gives the
CRAFT
port pinout.
