Restart
A restart
87
will delete or not delete the data in the control unit. Here
follow an explanation of the different data, abbreviations and a table
showing how the data respectively is affected.
FFD
= Fire alarms, faults and disablements.
SSW
= Week average sensor values, access codes, supervised output
calibration values and log buffers. (Alarm counter when applicable.)
SSD
= Site specific data, i.e. all the installation programming
downloaded from Win512.
SSI
= EBL512 settings downloaded from Win512.
S/W
= Software, i.e. the control unit system program.
Safe shut down of control unit
(menu H8/S8) will save the
SSW
data in a Flash ROM
before you power off
(de-energize)
88
the control
unit. Before the first "Safe shut down" this memory is empty. After
each "Safe shut down", the latest SSW data is saved. When the power
supply returns, the control unit RAM (working memory) will, after the
restart, read the SSW data saved in the Flash ROM.

NOTE!
During restart, the following will happen:
-- The Fault tx relay output will be "activated".
87
Restart affects the control unit where it is performed and that control unit's
data in a system.
88
A restart via jumper JP4 or an external disturbance might also delete the
SSW if the restart is in the middle of an un-controlled process.
89
If this memory is empty when the power supply returns, new week
average sensor values will be calculated within two minutes. During the two
minutes all fire alarms from analog smoke detectors will be suppressed.
90
See "Safe shut down of control unit" above.

If this happens often, call for service personnel / engineer.
