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
