ESSENTIAL FAULT CONDITION KEYS
The essential keys for fault conditions are <FAULT 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 Advanced Functions Section 6). Use of these
keys require advanced user skills.
3.4.1 Fault Acknowledge Key
The <FAULT ACK> key is used to scroll through the various displays on the alphanumeric
display. It also controls the Fault LEDs and the tone-alert. The <FAULT ACK> key is
located directly under the fault LED. Pressing the <FAULT ACK> key (twice for Individual
Acknowledge or once for Global Acknowledge) will cause the LED to change from flashing
to on steady and silence the tone-alert. When the <FAULT ACK> key is pressed, it will:
• Select the next unacknowledged fault point and display it on the alphanumeric display
(Individual Acknowledge).
• Acknowledge the displayed point or acknowledge all points on the list (Global
Acknowledge).
• Silence signals programmed to follow the Fault Acknowledge key.
• Scroll the points chronologically after all points have been acknowledged.
There are two types of acknowledges for the 4120 FIP: Global Acknowledge and
Individual Acknowledge. Each acknowledge type operates with the Fault Condition
in the following manner.
• When Global Acknowledge is used on the 4120 system, a single key press will
acknowledge all fault changes in the system. If status change information is required,
the user may review this data (after a delay) by pressing the <ACK> key and reading the
total number of fault changes on the alphanumeric display.
