Operation
The terms used in the displays described
above are defined as follows:
• ACK appears if the event has been
acknowledged; otherwise, the field is
blank.

restored.
• [time/date] shows the time and date the
event occurred.
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
