The terms used in the displays described

Internal Audible Alarm

The internal audible alarm (not visible)
sounds steadily when there is an unac-
knowledged fire alarm. It pulses if all
alarms are acknowledged, but there is at
least one supervisory, security condition or
trouble.
A 2-line display of 40 characters each that
shows the state of the System. A back light
turns on when any key is pressed or an
event is reported.
