ATLAS 550 System Manual Section 2 Engineering Guidelines
1. EQUIPMENT DIMENSIONS
The ATLAS 550 base unit dimensions are 17.08” W x 11.67” D x 3.47” H. The option modules fit inside
the base unit.
2. POWER REQUIREMENTS
The ATLAS 550 has a maximum power consumption of 60 W and a maximum current draw of 2 A
(AC System) or 5 A (DC System) regardless of the configuration of option modules installed in the base
unit.
3. REVIEWING THE FRONT PANEL DESIGN
The front panel contains the Alarm Cut-off switch (ACO), the CRAFT port, and the status LEDs for the
system controller, the network modules, and the option modules. Figure 1 identifies the ACO switch, the
CRAFT port, and the LEDs.

Figure 1. ATLAS 550 Front Panel Layout
Pressing the ACO switch deactivates (clears) the Alarm Relay, located on the back panel of the
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 CRAFT port to configure the system via an EIA-232 connection. Table 1 on page 28 gives the
CRAFT port pinout.
