Emergency and evacuation lighting luminaries connected to the Central Battery System are located in end circuits. Communication with luminaries takes place by means of the power supply line.

A controller with a touch display has a simple and intuitive interface and it allows for fast system configuration. Automatic performance of tests in accordance with EN 50172:2005 from the controller level. Both test results and reports on errors and failures are saved and kept on the internal SD card. It is also possible to save test results and reports on errors and failures on the external USB memory. Such a solution facilitates reporting and keeping the incident Log (in accordance with EN 50172:2005).

HVCBS uses hermetic and maintenace-free batteries paired in terms of internal resistance and voltage what aloows for long-term correct operation. The selection of batteries depends on loading and system operation time during emergency operation.

A temperature probe monitors temperature in the battery. The system has the signalisation of batteries discharging in accordance with EN 50171:2007. The use of dedicated safety devices for circuits, automatics and batteries affects the increase in the safety level. HVCBS System is dedicated to supply the emergency and evacuation lighting circuits in the IT network in the batery mode.

Battery housing types:

• cabinet
• rack
• fireproof cabinet

Central Unit housing types:

• one-section housing
• two-section housing
• fireproof housing
• housing with increased tightness to IP65
• mounting plate

During normal operation, the output voltage is obtained directly from the power supply, powered from the power grid, which additionally charges the batteries. During a power failure, the system goes into emergency mode and the 24V DC output voltage is obtained from batteries.

SYSTEM CONSTRUCTION

The system structure is made in 19-inch standard, which includes the following modules:

H-505 module is the main control unit in the HVCBS system, its main function include:

• monitoring and control of all internal system components
• communication with substantions
• communication with BMS (building management system)
• local interface based on the colour TFT LCD touch screen
• automatic testing in acc. with the EN 50172:2005
• saving tests results on SD card
• saving tests results and settings on USB stick

UKN module - allowing the measurement of parameters such as battery voltage, battery charging and discharging, load current and insulation state monitoring.

USI module - with potential-free contact inputs and relay outputs. Potential-free contact inputs may be paired with any lines and control them.

USO module - checking the condition of the luminaries in the final circuit. A single module allows to connect two final circuits.

Rectifier - used for battery charging, designed according to the EN IEC 62485--2:2018-9 standard. Owing to solutions adopted in the module, current surge after connecting to the network is ensured. Output specification of the rectifier with impulse output current limitation of the constant voltage-constant current type. It has over-voltage protection at the level 110-120% of nominal volatge (infinitely variable adjustment). Output valtage adjusted to temperature changes according to the requirements of batteries manufacturers.

External modules allows to extend the system capabilities:

USE module - external module allowing for extending the system with 8 additional inputs of potential-free contacts. Potential-free contact inputs may be coupled with any circuits and controlled. It is possible to select the mode of inserting potential-free contact inputs (short-circuiting, opening controled input, impulse controlled input). HVCBS may be extended max to 56 inputs of potential-free contacts.

USO ext - it is an external module allowing for extending the Central Battery system with additional 4 end circuits. This module as USO module allows for controling end circuits. Owing to a small size and ergonomic shape, it may be installed in places where the use of a sub-station is not possible. An additional asset of this appliance is economy resulting from fewer lines.

USE voltage module - external module allowing for extending the system with 8 additional inputs of potential-free contacts. Potential-free contact inputs may be coupled with any circuits and controlled. The module detects a power failure/power outage. The total number of additional USI+USE modules cannot exceed 7.

PW-01 module - allows for remote control of HVCBS confition. Basic parameters, such as voltage, current, operation mode, information on errors, tests and operation state is displayed on a transparent modern LCD.

Bus connected phase control module MCXF-1 is a device that allows remote monitoring of the presence of three-phase voltage. The connection of the modules is serial. Each module has its own individual address, set using the RS rotary switch and two switches S1 and S2. It is possible to address 61 sensors. The module is an alternative to many phase control relays, connected by multiple wires with additional USI modules. It allows to reduce the amount of necessary wires.

ECU (External Communication Unit) - is a module used to isolate and separate the internal communication of the system. It allows you to connect up to three additional communication modules (UART or DALI) that allow you to connect up to 64 external lines and up to 61 MCZF-1 modules.

DALI is a module that allows you to connect MCZF-1 phase control sensors. It can be in a free port of the H-505 unit or ECU module.

COMMUNICATION

Communication between the main station, sub-stations and external modules takes place by means of EIA/TIA-485 bus. The communication line uses 2 wire shielded twisted pair, e.g.. HTKSHekw 1x2x0,8. In HVCBS the working order of luminaries may be checked through line control (end circuit current measurement) or through the individual control of luminaries with the use of address modules. Communication with luminaires takes place along the power supply line, the system does not require a separate communication line.

The communication of the main station controller with H-312 Control Unit or computer set takes place through the Ethernet connector and allows for extending HVCBS with remote monitoring and convenient management. HVCBS controller (e.g.. H-505) cooperates with BMS (building management system) by means of MODBUS TCP/IP or RTU protocol and with back-up power supply systems. System configuration allows for monitoring the presence of voltage from basic lighting switching stations in accordance with EN 50172:2005.
