THE BASIC PROGRAMME:
Up to 32 Bosch Praesideo Controllers can be accessed over a TCP/IP network with
audio being routed via Cobranet or other means from the main Praesideo
controller to the remote Praesideo controllers.
Up to 128 zones can be configured with zones spread across several Praesideo
controllers if needed. Zones can be grouped either in the front end software or
in the Controllers with up to 64 Groups in the software. Each Group can contain
up to 128 zones each. The same Zone could be in several Groups depending on the
requirements.
Zones could also be grouped in to Buildings with up to 32 Buildings displayed on
the screen. Buildings are basically the same as Groups and it gives a further 32
'groups' to display.
Pre-recorded messages can be stored in the PC or Praesideo Controller to be
broadcast to selected Zones.
If the messages are short and only broadcast to Zones within a single Praesideo
Controller then they can be stored in the Controller and selected via the
software. If messages are lengthy or there are a lot of them which are
constantly changing then they are best stored on the hard disc of the PC. This
also has a major advantage where there are several Praesideo Controllers linked
via a TCP/IP network. A message stored within the Praesideo Controller cannot be
sent to other controllers over the network but a message stored within the
PC can, as a call can be started to all the relevant Praesideo Controllers and
the message from the PC routed to all of them via the main Praesideo
Controller over the Cobranet network.
The Basic programme can only handle 10 messages but the more sophisicated Call
Station can handle 100 messages with the output zones preselected or selected
before the message is played.
Also the if the messages are stored in the Bosch Praesideo Controllers then the
same message must be stored in every Controller which means a lot of work if a
message has to be altered or added.
The Message panel can show messages stored in the PC and those stored in
the Praesideo Controllers.
The messages panel is normally moved off to the right and displayed when
the Show Messages button pressed. It can be passworded so that unauthorized
users cannot send pre-recorded messages over the network
The status of the the current call within the Bosch Praesideo Network Controller
is shown on the right of the screen. It shows whether the Start Chime, Messages,
Microphone, or End Chime is active. Also there is a progress bar which shows the
amount of Talk Time is left. The Talk Time can be configured so that if, by
accident, the Microphone is left open and the PTT is latched, the programme will
automatically end the current call.
The status of any faults etc within the whole Bosch Praesideo Network is on the
left.
The programme can also handle a Redundant Controller setup where there are two
main Praesideo Controllers with one remaining inactive. Should the active one
fail the system will automatically switch to the redundant Controller. The
Programme will detect the switch and automatically connect to the standby
Controller. The status of which Controller is in use is also displayed. When the
Main Controller is repaired and the system switched back the programme will also
switch back. Any calls in progress will be aborted by the switchover and will
have to be restarted by the user.
there is the possibility to restart any call that had been started when the
switchover has finished.
Additional Features
There can be full control of background music playing across the network or
locally within a single Bosch Praesideo Controller.
Contacts in or out can be detected by the programme to perform any task such as
start a call, display on a panel or send an evac or alert message. In fact any
action can be started by the Programme.
The programme can also detect when a Call Station on a remote Praesideo
Controller is activated (requires some setting up to achieve) and can route the
Call Station microphone to the rest of the Controllers, or a selection of
Controllers, via the main Controller and Cobranet Network. The Praesideo Network
is incapable of achieving this without a programme to control it.
The basic Call Station software just deals with normal voice calls and message
transmission but the programme can be written to provide any facility required
by utilising Contacts in or out on any Bosch Praesideo Unit in the network or
monitoring calls started locally on a remote Bosch Praesideo Controller using a
Bosch Praesideo Call Station.
If the system is connected to a fire panel it can provide automatic transmission
of safety messages via the PC Interface.
There is really no limit on the number of Praesideo Controllers, Zones, Groups
etc which can be accessed and can be increased to whatever is required.
Also any layout is possible even using multiple screens to display different
areas - especially useful if a large number of Zones is required.
