25.2 LCD Operational Changes
With Revision N, if an alarm, trouble, or supervisory condition exists, the LCD scrolls the words ALARM,
TROUBLE, or SUPERVISORY. You can then press STAT to display the zone number and location of
trouble and supervisory conditions. Press MEM to display the zone number and location of alarms.
25.3 Memory Reporting During Auto Test
When an Auto Test occurs, the Model 4720 also sends a report of all unrestored events. It is not possible to
distinguish between old and new events during an Auto Test. Treat all alarms, troubles, and supervisories as
if they were new events. Note that memory reporting is not yet available with the Models 4724 and 4734.
