Release notes
Bosch Security Systems B.V.
– A bug fix has been implemented to solve an issue that appeared when Background music
was muted. When automatic volume control was configured in combination with BGM
there was a possibility that when BGM was muted, amplifiers started to disconnect/
connect to the system.
– A bug was fixed that in rare cases a high priority call stopped all running calls that were
playing a message in the start chime phase.
3.8 Release 1.40
– Support for the new PRA-ANS Ambient noise sensor. The unit monitors changing ambient
noise levels for automatic adjustment of announcement or background music levels (AVC
- Automatic Volume Control). This insures the public address audio is set at a
configurable level above the ambient noise in order to guarantee intelligibility of
announcements, yet at a comfortable level. Upon failure or disconnection of the device,
the announcement volume of the subscribing amplifier channels is automatically set to its
maximum within the applicable control range.
– Support for the PRA-CSBK Call station kit, basic, which will be available by November
2021. The Call station kit, basic is an open frame call station to create dedicated, fully
customized control panels with a CAN bus interface.
– Make announcement with zone selection is now available as an additional function for
extension buttons. This function can be assigned to buttons and is similar to the Make
announcement function, but without the pre-configured zone / zone groups selection.
Using the Make announcement with zone selection function, a pre-recorded message,
based on a call definition, can be started aborted/stopped in one or more manual
selected zones / zone groups.
– Zones and zone groups can now be configured to the call station’s Push‑To‑Talk button to
make live announcements without connecting to a call station extension. It simplifies the
handling of basic calls that are always going to the same zone or zone group. Zone
selection from a Call station extension can be done in parallel.
– Traditional Chinese is available and added to the language selection for the Graphic user
interface of the PRA-CSLx.
– Functionality is added in preparation for certification to the North American standard for
mass notification systems:
– English (UL2572) is available for language selection. This language selection is used
for mass notification systems and will set Configuration software and Graphic user
interface of the PRA-CSLx to a specific English, that complies to UL terminology.
– For each device a check box is added to General setting, which is set to Emergency
relevant on default. Troubles (faults) that occur on devices that have assigned
Emergency relevant will reported as Mass notification system faults.
– Class Mass notification is a new option in General settings of PRA-CSLx. Class Mass
notification let the Call station act as a First responder panel for Mass Notification
Systems (MNS). Emergency group is a new set of functionality, that allows multiple
first responders (fire fighters) to control the evacuation of a building from multiple
locations in which each has, one or more, First responder panel(s) (FRP’s) in use.
– Transfer of control is a new function, that is only available when Class: Mass
notification and Emergency group are set. In order to avoid confusion among the first
responders (fire fighters), actions are only possible on one First responder panel at
the time. That First responder panel is then 'in control'. It is possible to force the 'in
control' state and to grant or deny a request.
