The simple solution for your fire compartment


A low power supply system (LPS system) is a decentralised emergency lighting system with limited power, typically for supplying the emergency luminaires in a fire compartment in accordance with DIN EN 50171.

Technology & practical benefits

Cost effective installation:
Elimination of functional maintenance cables reduces installation costs per fire compartment.

Flexible end circuits:
Up to four end circuits with a maximum of 80 luminaires can be supplied within a fire compartment; two end circuits are possible in mixed operation.

Maximum extension:
Up to eight end circuits in maximum extension

Central monitoring:
Remote monitoring via TCP-IP network; status messages can be viewed via web server

Visualisation and operation:
Central visualisation and operation interface via web browser

Bridging time:
Options for 1 h, 3 h and 8 h bridging time

Battery technology:
Lithium battery technology systems

The benefits of lithium battery technology

Lithium battery technology offers many advantages over traditional battery technologies. One outstanding advantage is that they are gas-free, which means no special ventilation systems are required, significantly reducing installation costs. Lithium batteries also have an impressive lifespan of over 15 years, reducing maintenance costs and minimising the need for frequent replacement.

Gas free:
No special ventilation systems required, significantly reducing installation costs.

Longer life:
Over 15 years, reducing maintenance costs and minimising the need for frequent replacement.

Less weight and space:
Lithium batteries are up to two-thirds lighter and more compact than conventional batteries.

Intelligent safety monitoring:
An advanced Battery Management System (BMS) continuously monitors key parameters such as temperature and voltage and protects against deep discharge and overcharging.

High efficiency:
Up to 90% of stored energy can be recovered, regardless of the duration of discharge (1hr, 3hr or 8hr).

Temperature resistant:
Lithium batteries work reliably at temperatures from -30 to +60 degrees Celsius and their life is hardly affected at temperatures up to +40 degrees Celsius.

Environmentally friendly:
No acid resistant paint required, less hazardous waste due to longer life and less frequent replacement.

Applications for our low power systems

Our LPS systems are ideal for:

  • Fire compartments: Distributed supply for efficient and cost-effective installation
  • Commercial and industrial buildings: Provide emergency and security lighting without complex cabling
  • Public institutions: Reliable lighting for schools, hospitals and government agencies
    LPS systems provide a simple, flexible and cost-effective solution for emergency lighting in different fire compartments. They provide centralised monitoring and safety in the event of a power failure.
