19 Restart
A restart may delete some data in FT128. Below follows an explanation of the different
data, abbreviations and a table describing the different restart alternatives and how the
data respectively is affected (cold or warm restart).
FF = Fire alarms and Faults.
D = Disablements
FFD = Fire alarms, Faults and Disablements.
SSW = Sensor min. / max. values and performance factor, password, supervised
output calibration values and event log.
WASV = Week Average Sensor Values
SSD = Site Specific Data, i.e. all the installation programming created and
downloaded via EBLWin.
S/W = Software, i.e. the EBL128 system program.
The date & time and alarm counter value is stored in the memory of the real time clock,
i.e. the value will be retained also after the FT128 powered down.
Note: After any restart, a new week average sensor value will be calculated within 2
minutes, for all the Analogue smoke detectors
57
. Thereafter a new average sensor value
will be calculated each week.
19.1 Safe Shut Down
Safe shut down of control unit via menu H8/S7 will save the SSW data in a Flash ROM in
FT128. Before the first "Safe shut down" of the control unit, this memory is empty. After
each "Safe shut down" the latest SSW data is saved. (Safe shut down will not save the
week average sensor values)
When FT128 is powered up, a restart takes place and the RAM (working memory) will read
the SSW data saved in the Flash ROM.
19.2 Restart Table
