5.3.11 Compact flash card
Praesideo stores digital audio messages on a type 1
compact flash card. Although flash cards up to 4 GB are
supported, only the first 128 MB are supervised and
suitable for emergency messages. This is equivalent to
the first 25 minutes of the message set. A 4 GB flash
card can store more than 13 hours of audio messages.
A specially selected compact flash card is supplied
together with the network controller. This card does
automatic refreshing of the data, permitting very
frequent reading of the content for the purpose of
supervision. Do not replace this card with just any
compact flash card, but contact the spare parts logistic
channel or your local Bosch contact person for a
selected new compact flash card.
5.4 Installation
The network controller is suitable for either table-top or
19-inch rack installation. Four feet (for table-top use)
and two brackets (for rack installation) are supplied.
Note
The electronics inside the network controller are
susceptible to electrostatic discharges. Wear an
anti-ESD bracelet during the installation of the
compact flash card.
Warning
To prevent the hazard of electric shocks, discon-
nect the mains cord from the network controller
before starting installing the compact flash card.
To reduce the risk of electric shock do not
perform any servicing other than that contained
in the operating instructions unless you are
qualified to do so. See section 1.2 Intended
audience.
Note
The center bracket positions can be used to
secure the unit on a table or shelf. They can also
be used to install the unit vertically to a wall.
