Installation and Operation manual
Compliance
All Plena Voice Alarm System programs
(executable code and data) are stored in
Flash EEPROM.
Firmware (i.e. the program) can be
replaced using the File Transfer
Application. Using the File Transfer
Application requires access level 4.
The version of the firmware of the units is
visible on the units It is noted on the rear
of the unit (access level 3).
Alteration of configuration can only be
done via the configuration program or
access to the units from the rear. This
includes the File Transfer Application
(message sets). Getting access to the
configuration of the controller requires
access level 3. Using the File Transfer
Application requires access level 4.
Configuration of the Plena Voice Alarm
System is implemented to be data-driven
and is not part of the program
executable. Also transferring message
sets to the Plena Voice Alarm System is
data-driven and is not part of the
program executable. Therefore alteration
of the site specific data does not affect
the structure of the program.
Site specific data is stored in a Flash
EEPROM based file system. Writing of
data is only possible via the password
protected PC program.
Site specific data can be viewed and
maintained from the configuration (PC)
program. Using the configuration (PC)
program requires access level 3.
