Questions & answers
Know before you buy
Quick answers about the PRA-LSPRA, and how it compares.
What is the Bosch PRA-LSPRA license used for in a PRAESENSA system?
The Bosch PRA-LSPRA is a subsystem software license that connects multiple PRAESENSA systems through a master–subsystem architecture. It enables coordinated announcements, system-wide status reporting and management of connected subsystems. One license is required on the master controller for each connected subsystem.
How many PRAESENSA subsystems can one Bosch PRA-LSPRA master controller support?
A PRAESENSA master controller can connect up to 20 subsystems using PRA-LSPRA licenses. Bosch specifies a maximum multi-system architecture of 3,000 devices and 10,000 zones. Actual system design must follow the manufacturer's controller capacity, configuration and networking requirements.
Do PRA-SCL and PRA-SCS system controllers support PRA-LSPRA licensing?
Bosch documents PRA-LSPRA licensing for compatible PRAESENSA system controllers, including PRA-SCL and PRA-SCS in the relevant configuration manual. Activating subsystem licenses allows an appropriately configured controller to operate as a master controller. Compatibility should be checked against the installed controller firmware and PRAESENSA software version.
How can I connect multiple Bosch PRAESENSA systems for centralized announcements?
PRA-LSPRA allows multiple PRAESENSA installations to be organized under a master controller with connected subsystem controllers. The master can initiate business announcements across selected remote zone groups, including groups containing zones from different subsystems. Audio for multi-system calls is synchronized according to Bosch's supported architecture.
Can Bosch PRA-LSPRA support centralized emergency announcements and fault monitoring?
Yes. In a properly configured PRAESENSA multi-system installation, PRA-LSPRA supports system-wide emergency announcements from a compatible EN 54-16 certified fireman's microphone, along with remote zone status, fault reporting and emergency acknowledgement or reset. These functions depend on the approved system configuration and connected equipment.
How many PRA-LSPRA licenses are required for primary and redundant master controllers?
Bosch requires one PRA-LSPRA license per connected subsystem on the primary master controller. A redundant master controller requires the same number of active licenses. For example, connecting six subsystems requires six licenses on the primary master, or twelve licenses in total when an equally licensed redundant master is included. Subsystem controllers do not need PRA-LSPRA licenses.
What is the Bosch PRA-LSPRA price in Pakistan, and where can I buy it?
