Integration with DaisaTest system for maintenance management (EN-50172).
The DBR system can also be installed in ELC-type luminaires.


2 auxiliary inputs for remote actions.
Communication port for EV-BUS.
1 x 230 V output for installation of EV-ALIM bus power source.


5 dry contacts for faults, alarms and central battery status (EN-50171).

Internal operation diagram

Each CB unit output circuit is configured as "maintained / nonmaintained" and assign this operating mode to all luminaires without communication (non-ELC) connected to said circuits.

If the unit and luminaires are communicated (ELC), "maintained / nonmaintained" operation is individually configured in each luminaire and is independent of the circuit configuration.

The DaisaTest application can monitor and control an indefinite number of units. No communication accessory is required.

centralised systems for emergency lightingExecution of actions.

The monitoring unit controls the most critical aspects of safety (EN-50171) of the CB units such as the status of the battery-charging rectifier, the general condition of the central battery, the status of the inverter, status of the output circuits and runs functional, duration and battery capacity tests.

It controls the charge voltage and current of the batteries and their temperature.

A control panel with graphic LCD display enables data monitoring and performs the following configuration tasks:

Definition of the general duration of the central battery or output circuits.
Configuration of the output circuits as maintained / non-maintained and ELC luminaires.
Configuration of the frequency of the tests, day of the week, test schedule, automatic/manual mode.
Input configuration.
Output configuration.
Configuration of EV-DR and EV-PD detectors.
SD card with central battery configuration log, test results and status of the ELC-type luminaires.

Remote EV-DR network fault detector.
Network fault detector for CB series centralised unit.
Monitors the status of the network (3 phases and neutral) which it shows by flashing a front-mounted LED (off during network downtime).
In the event of a network failure it sends a signal via the EV bus to the CB unit which enables configuration of the command to activate one or more output circuits.
Sending signal to centralised unit via EV bus.

systems for emergency lighting

Level detector EV-PD.
Level detector for CB series centralised unit.
It has two monitoring inputs (1-2 and 2-3) that enable configuration of activation order of one or more central battery output circuits.
Sending signal to centralised unit via EV bus.

systems for emergency lighting

Bus power source EV-ALIM.
Power source for EV devices connected to centralised CB series unit.
It supplies the devices connected to the unit through the EV bus itself.
The number of devices supplied depends on their distance from the power source.
The capacity is a maximum of 10 devices at a distance of 400 m.
