Fire extinguishing: Innovation from Bosch: conservatism of reliability and flexibility in the design of modern fire alarm systems.

Such a difficult and, at first glance, contradictory task is solved by the BOSCH company, offering new solutions on the market of fire alarms and fire automatic systems in general.

The rapid development of engineering and information technologies forces us to look for new ways to implement systems, the core of which remains the fire alarm system. Bosch Security Systems offers to combine the traditionalism of fire alarms with the latest detection and communication technologies. The innovative system developed by the company is based on three main principles: early detection of an alarm, reliable means of delivering a signal to the operator and its clear visual display. And all this is achieved with the help of the FPA-5000 modular station. When creating it, the experience and improved technology of working with LSNi detectors, intermodule and interpanel communication based on CAN and, finally, an Ethernet connection to the automated operator workstation using OPC technology as a means of a standard interface with graphic control and management programs were used.
The OPC standard, widely used by developers of engineering systems, allows for easy integration of fire alarm systems based on FPA 5000 panels into a single set of building life support systems without having to delve into the intricacies of protocols and without involving additional resources. Thus, the operation service receives all the information in a single, familiar form, and those responsible for fire safety can use the wide-format liquid crystal display of both the station itself and the remote control for local operational control of the entire fire situation.
For clarity, the following interaction diagram can be provided:

 Integration of the entire security system into the building management system
 Interaction with the voice alarm system
 Reliable CAN network technology from Bosch
The panel network is created using CAN technology developed by Bosch and widely used in the automotive industry for decades. This solution ensures high stability of operation and complete network safety in case of cable damage.

Distinctive features of CAN technology:
 High immunity to interference;
 Arbitration of network access without loss of bandwidth;
 Reliable control of transmission and reception errors;
 Packet data transmission and a wide range of speeds.

The modules that make up the fire control panel are housed in extremely robust housings to protect all components from mechanical damage and static discharge. Hot swapping of modules allows changing the panel configuration without disconnecting the power supply. The control panel modules and peripheral devices are automatically recognized by the system's central controller, which significantly speeds up installation and simplifies setup. The system is programmed using Russified software with an intuitive interface, which is included in the delivery set, and the Fire System Designer (FSD) specification creation and verification program allows you to quickly and accurately create a system configuration.

Technical characteristics of the 5000 series fire control panel:
 from 1 to 32 loops
 up to 4096 addresses
 loop length up to 3000 m
 current in the loop up to 1500 mA

The Local Security Network (LSNi) addressable technology used by Bosch in the development of fire alarm systems provides the highest level of reliability, response speed and information content. A double short-circuit isolator is built into each addressable device to maintain the operability of all elements of the loop in the event of a fault.
The following main components are connected to the LSNi addressable loop and centrally configured via the control panel:
 Automatic addressable fire detectors (optical, thermal, combined, including with a CO channel);
 Addressable manual fire alarms;
 Addressable sound and light alarms;
 Addressable interface modules;
 Addressable indicator panels;
 Addressable aspiration systems for early fire detection;
 Redundant power supplies connected to an addressable loop.
The modularity and versatility of the Bosch solution allows you to build fire protection systems of various configurations for facilities of any level and meet the most stringent requirements and standards. This approach means that any panels and components can be combined with each other for expansion, providing flexibility in designing a system for any application. The fully modular FPA-5000 fire alarm system is another innovation from Bosch in the development of equipment for the end user. Bosch Security Systems offers you solutions made for the future, characterized by operational flexibility and versatility today.
