Abstract
An emergency operating arrangement for at least one building technical device is provided, comprising a power supply unit, and an emergency supply unit, the power supply unit and the emergency supply unit being adapted to be supplied by an electrical supply and being configured to output a DC voltage, wherein the emergency supply unit is configured to detect an emergency situation and being configured to output a DC voltage higher than the DC voltage output by the power supply unit when the emergency situation is detected.
Claims16
Emergency operating arrangement (EOA) for at least one building technical device (L), comprising:
- a power supply unit (PSU) that is configured to output DC power at a first fixed voltage level;
- an emergency supply unit (ESU) that is configured to output DC power at a second fixed voltage level that is higher than the first fixed voltage level;
- and
- a switch that is able to receive DC power from the power supply unit and from the emergency supply unit and that can be controlled to output one of DC power from the power supply unit at the first fixed voltage level or DC power from the emergency supply unit at the second fixed voltage level;
- the power supply unit (PSU) and the emergency supply unit (ESU) being adapted to be supplied by an electrical supply (ES), wherein the emergency supply unit (ESU) is configured to detect an emergency situation and control the switch to output the DC power from the emergency supply unit at the second fixed voltage level when the emergency situation is detected, thereby signaling to the building technical device (L) that the emergency situation has been detected.
Building technical device (L), comprising:
- an LED lighting module;
- at least one input terminal, and
- a DC/DC converter configured to output DC power to the LED lighting module at an appropriate voltage level for the LED lighting module, wherein the DC/DC converter is also an emergency converter that detects DC voltage supplied at the at least one input terminal, and operates the building technical device (L) in an emergency operating mode, in particular to dim the LED lighting module, when the detected DC voltage increases above a threshold value.
Method for operating at least one building technical device (L), the method comprising the steps of:
- supplying power from an electrical supply (ES) to a power supply unit (PSU) and to an emergency supply unit (ESU);
- configuring the power supply unit (PSU) to output DC power at a first fixed voltage level;
- configuring the emergency supply unit (ESU) to output DC power at a second fixed voltage level that is higher than the first voltage level and higher than a threshold level;
- using the emergency supply unit (ESU) to detect whether an emergency situation exists;
- supplying DC power from the power supply unit to the building technical device (L) at the first fixed voltage level when no emergency situation is detected;
- supplying DC power from the emergency supply unit to the building technical device (L) at the second fixed voltage level when an emergency situation is detected;
- using the building technical device to detect whether the voltage level of the DC power supplied to the building technical device is above the threshold level, and if so operating the building technical device in an emergency mode.
