PRE-ALARM STATE

The Pre-Alarm State occurs when a SmartOne automatic initiating device (such
as a smoke detector) senses a fire signature that is below its configured alarm-
threshold value but above a lower-threshold value called the "pre-alarm"
threshold. The ARIES can also enter the Pre-Alarm State if it receives a Pre-Alarm
Level-1 or -2 signal reported by a high-sensitivity smoke detector (HSSD)
communicating through the Intelligent Interface Module (IIM).
The upper line of the LCD display shows the pre-alarm event by the device
address, the change of state, and the device type. The lower line indicates the up-
to-40-character message assigned to the alarm device using the ARIES
configuration program.

and ATM-Ls, if applicable
