ESSENTIAL SUPERVISORY SERVICE CONDITION KEYS
The essential keys for supervisory service conditions are <SUPV ACK> and the <SYSTEM RESET> keys. The
remaining keys are concealed by the access door and are associated with advanced functions of the system. (See
Section 10, Advanced Functions.)
SUPERVISORY ACKNOWLEDGE KEY
The <SUPV ACK> key is used to scroll through the various data fields on the alphanumeric display. It also controls
the SUPERVISORY SERVICE LED and the tone-alert. The <SUPV ACK> key is located directly under the
SUPERVISORY SERVICE LED. Pressing the <SUPV ACK> key (twice for Individual Acknowledge or once for Global
Acknowledge) causes the LED to change from flashing ON to steady ON, and silences the tone-alert. The <SUPV
ACK> key press does the following:
• Selects the next unacknowledged supervisory point and shows it on the display (Individual Acknowledge)
• Acknowledges the displayed point or acknowledges all points on the list (Global Acknowledge)
• Scrolls the points chronologically after all points have been acknowledged.
NOTE: The <SUPV ACK> key may be passcode protected. If you do not have the required access level, you will
not be able to acknowledge supervisory conditions. See Operator Access Levels (Section 9) and the Log
In Procedure (Section 1) for details.
