How many panels do I need?

This is very much dependent on the installation.  The cost of an addressable emergency lighting installation is dominated by the cost of luminaires and the panels are a much lesser peripheral cost.

Decisions on quantities of panels should be made in line with ease of installation and the choice of how to monitor those panels.

Each panel can monitor up to 996 lights, where the lights are wired 249 per loop.  Sometimes loop wiring can be costly and it may be beneficial to install a single loop panel per floor in a large building, rather than one panel in a central location.

It is always beneficial to not exceed 80% capacity on loops and panels, as this will allow for possible minor alterations and additions in the future without large scale changes.

Monitoring can be achieved by the use of serial to Ethernet converters and simply adding the panels to the sites local area network.

Do I need to install isolators?

No isolators are required.  On detection of a short circuit, the loop will shut itself down to protect it.  In the event of an open circuit, the loop driver will continue to communicate from both sides, so as to loose communications with a minimal number of lights.

How many lights can I connect to each loop and panel?

The Lux Intelligent panel can support up to 4 loops and 200 panels can be networked together into a system covering huge areas, with 800 loops and thousands of lights and luminaires.

Each loop is capable of communicating with 249 addresses on a single loop.  This can be actual lights, or input/out devices.

The number of devices on a loop is limited by the choice of data cable used and the length of the data loop.  As the loop driver has a limited maximum current, it is possible to define the number of devices and length of loop once the choice of cable is made.  A typical data cable with an cross sectional area of1.3mm2 (AWG 16), can extend for 1500 meters.

Can I add new devices to an existing network?

Yes, you can add additional lights to your emergency lighting system at any time, provided you have enough capacity on the Lux Intelligent emergency light testing system.  See "How many lights can I network on each loop and panel?"

Adding additional lights to the network is a two step process.  Any additional lights added to a live system will require the new lights to be connected to the data loop.  This is initially achieved by isolating the data loop and breaking in to it at an appropriate point (normally a light close to the one(s) to be added.  The integrity of the loop should be maintained by running a new connection to the new light and then in turn, running a data connection from the new light to the next light in the existing loop.

At the panel, the 'search' feature should be used to find the new light, allocate a new address (the next free address, bearing in mind addresses do not need to be allocating sequentially as the lights as wired).  A prompt for an autolearn will be made and after completion, text, zone information and test group numbers can be added.  The new light is then on the system.  The panel aspects of the configuration can also be achieved using the PC based configuration tool software.

Are Lux Intelligent PLU Modules required to be fitted to our lights?

Yes, the Lux Intelligent panels can only communicate through the PLUs and without them, the monitoring and testing features cannot be achieved.
