Bosch Security Systems B.V.
multi-controller system, it is possible to make calls from the master system to the
subsystems. For emergency purposes, the multi-controller system operates as a single
large system: The emergency state and the fault state are propagated from subsystem to
master and from master to subsystem. This feature complies with emergency standards,
but it is not compliant with DNV-GL Type Approval.
Support of the licensing mechanism to enable multi-controller systems, as well as other
future functionalities.
OMNEO platform upgrade to enable multi-VLAN support for PRAESENSA. PRAESENSA can
now be installed in networks that are divided by a router in multiple sub networks.
Support of OMN-ARNIE and OMN-ARNIS supervision. In case of redundant deployment,
both the primary and the secondary devices are supervised. Multi-VLAN installations
require the use of OMN-ARNIE devices to enable device discovery and audio clock
synchronization.
Switch supervision based on secure SNMP V3: The Cisco IE-5000-12S12P-10G router/
switch and the PRA-ES8P2S (software version 1.01.06 or higher) are part of the network
supervision to be able to detect defective or redundant network connections The
switches are supervised for presence and power supply.
Support of the single press push-to-talk button (PTT) for a business call station: A call
station in sleep mode is activated with the first press of the PTT button. The call starts
immediately. This feature is especially convenient when no extension keypad is connected
and a handheld microphone is in use.
The bug fix that a battery leakage fault could not be reset after disconnecting the battery
was resolved.
High audio level on amplifiers no longer leads to audio interruptions due to false positives
in the 100 V line supervision.
A potential weak point in the audio path supervision has been fixed. In rare cases, it could
happen that an Amplifier channel fault (caused by a broken H‑bridge MOSFET) was not
detected.
A bug fix has been implemented to resolve the issue that in some cases a System
controller watchdog reset occurred while making a call on a Zone where volume was
controlled by an Ambient Noise Sensor.
In accordance with the North American standard for Mass Notification Systems, the
software language set of English (UL 2572) has been revised and expanded in UL 2572
terminology.
The Call station indicator test has been extended to the LCD display, in cadence with the
microphone LED ring, the display will show the identical colors.
A bug fix has been implemented to resolve the issue that under certain conditions an
"Amplifier channel fault" with "Severity: High" got the status "resolved" when on the
same amplifier channel a fault occurred with "Severity: low" priority.
For compliance to the Chinese GB16806 standard the translation of "EOL fault" into
Simplified Chinese language was changed to a translation in standard-compliant
terminology.
