CLS 24 - The emergency lighting (r)evolution
Get to know everything about the success story.
Talking about an emergency lighting revolution with the CLS 24, comes close to the influence, which the system has on the German emergency lighting market. INOTEC introduced the first decentralised CLS 24 system with 24V output voltage in 2006 and by now the decentralised concept within the fire compartments has established itself at the markets. Now INOTEC takes a step forward with the CLS 24.1 7Ah.
An even smaller system with two circuits and 7Ah-battery can be used, where single-battery systems with their disadvantages have been used before. The advantages became already clear regarding the big brother with 4 circuits in different capacities.
You can find additional information in the brochure or in the video below.
The DIN VDE 0100-718 from 10/2005 claims that the safety lighting is blocked during shutdown times to prevent the unwanted discharge of batteries. For self-contained luminaires this is only possible, when a controller is used centrally! Therefore a separate BUS-line, which increases the wiring costs additionally, is normally required.
With the CLS 24 system the luminaires can be blocked at any time at the device or via status panel in central position! An additional BUS-line is not required!
Safety can be beautiful too
Especially nowadays the safety lighting needs to be as discreet as possible. The self-contained luminaire is restricting the design of the luminaires, because of the required battery and electronics tho.
For our CLS 24 luminaires the design can be very small and visually appealing due to the 24V technology (protection class lll, SELV) and the unnecessary battery in the luminaire!
Safety depends on the wiring
Via tapping at a power outlet circuit or the separate securing of the self-contained luminaires the protection goal is not reached. The emergency lighting does not turn on during a failure of a general lighting! Therefore the connection of the charge phase has to take place behind the fused outgoing circuit and in front of the light switch. Especially in existing constructions this is not possible anymore. This leads to complicated wiring, which can be defective, in practice.
When using the INOTEC CLS 24 system the wiring can be done easily from the device. No cable routing is required in functional integrity, because the system is designed for a fire compartment. Because the monitoring of the general lighting works at the device, the turning on of the standby lighting is secured even in case of a local failure in the general lighting.
Reducing the number of luminaires
An important point of the planning is the luminous flux reduction of the safety luminaires with single-batteries in emergency mode. Especially at projects with a rated duration time of several hours more luminaires need be planned in and installed on the center line of the escape route to achieve the required 1lx acc. to DIN EN 1838.
The CLS system has no luminous flux reduction in emergency mode! Via optimised power and lighting engineering the identical area is illuminated with less luminaires.
No problem for outside areas
According to DIN EN 1838 from 10/2013 safety lighting is required outside of each emergency exit up to a secure area. Not only low temperatures in winter, but especially high temperatures during summer affect the batteries of the self-contained luminaires negatively. An early exchange of the batteries, which is combined with high costs, is the result. The heating, which is used for batteries in self-contained luminaires, is uneconomic and offers no solution for the high temperatures during summer.
There are no problems using the luminaires of the CLS 24 system in outside areas , because the luminaires are supplied centrally from the device.
For the sake of the environment
Especially the efficiency for self-contained luminaires is often concealed. Not only for the changing of the batteries costs arise, but also the much higher workload. Often even working platforms are required to be able to maintain poorly accessible luminaires. For the CLS 24 there are only 2 central battery blocks in the device, which can be exchanged easily. This is not only more economic, but also considerate for the environment.
