Dimensional drawing

 

Function

        1) The switching time between the main centralized power supply and the secondary centralized power supply is less than 3 seconds.

        2) Low location lighting centralized power supply output voltage is DC24V.

        3) Emergency time 90 minutes (including lead-acid battery).

        4) The low location lighting centralized power supply has a total of 6 outputs, and the maximum working current of each circuit does not exceed 3A, and the total output power is less than 300W.

        5) The low location lighting central power supply simultaneously supplies power to the LED light belt and emergency signs.

Typical layout

 

        The Low Location Lighting (3L) system is a completely self-contained system that remains in standby mode until activated. The system can be activated in the following ways:

1) Manually flipping a switch on the low location lighting centralized power surface;

2) An input signal from the low location lighting controller;

3) An input signal from the fire detection system;

4) Failure of the mains or emergency power supply;

5) Pressing the test button on the centralized power supply unit.

       Once activated, the low location lighting system is capable of independent continuous operation, and in the event of an emergency power failure, the built-in battery pack (battery life of 5 years) guarantees the system to operate for at least 90 minutes.

       The low location lighting (3L) system features dual redundant centralized power supply. In case the main centralized power box fails to work, the system will automatically switch to the secondary centralized power box to ensure its continuous and stable operation.

       The low location lighting (3L) system has dual redundant communication functions. The centralized power box can communicate via optical fiber as well as through the 485 master/slave handshake. If any communication line fails, the system will automatically switch to another one to maintain its stable and continuous operation.

        The low location lighting (3L) system comes with digital management functions. Through the main interface of the centralized controller software, users can start the whole system with one click, shut down the whole system with one click, configure the partition, IP address and name of the centralized power supply, and precisely control the on/off state of the centralized power supply and the circuit switching state. It enables digital management of the centralized power supply, loop status, battery parameters and battery temperature via the centralized controller.

        The low location lighting (3L) system has a 3D digital twin function. Equipped with 3D visualization software for the ship's dynamic digital twin, users can intuitively view and control the layout and working status of the ship's low location lighting system and other digital twin functions in the centralized controller.

        The low location lighting (3L) system has the functions of importing fire evacuation plans and providing auxiliary decision-making. Based on the pre-imported escape path plans, combined with the input signals from fire alarms or drills and the regional personnel density signals from AI monitoring cameras, the built-in control software of the centralized controller makes comprehensive judgments and analyses and activates the three-dimensional digital ship escape and evacuation plan to achieve intelligent security for the safe evacuation of personnel on board.

The strobing and POE camera shown, as well as the LED-Strips and LED-Signs, can be selected and customized according to the user's needs，non-regulatory mandatory configuration.
