7.0 SYSTEM AND CONTROL OPTIONS
The System and Control menu allows you to configure the AC8—setting up inputs and outputs and an
input/output matrix to trigger actions, the modem and pagers, and system features such as date and
time. This menu also provides a vehicle for manually changing the state of an output to ON or OFF,
clearing active alarms and deleting records from the AC8’s alarm log, event log and trend logs.
The arrows
↑↓ are used to scroll through the menu. The Enter ↵ key is used to select the menu item
and enter new information. Table 14 shows characters that may be entered in labels and values.
The System and Control options require a password to prevent unauthorized users from making
changes to the system.
This section presents step-by-step instructions for each of the following:
• Login - enter the password
• Setup System - configure inputs, outputs, modem, pagers, system features
• Override Output - manually override automatic control of outputs; release the override
• Clear Alarms & Logs - clear active alarms; delete records from the alarm, event and trend logs
