What fault notification features does Lux Intelligent offer?

The Lux Intelligent system offers 3 levels of fault notification in respect of the emergency lighting installation.

As the emergency light testing panel regularly 'talks' to each light, it can report real time faults such as no light due to a failed tube, or a low battery due to a blown battery or battery disconnection.

Secondly the panel will report if a light fails a test, and will provide details of that failure reason.

And finally the panel also reports other faults that may occur on an installation which is not directly down to the lights themselves.  This could include the event of a local distribution board going down depriving a number of lights of normal mains supply, or alternatively a fault arises with the monitoring system such as an open circuit on the data loop.   As with the faults with lights, the panel provides additional information to help resolve the fault i.e. which zone has the power outage, or driving the data loop from one end to determine where the break maybe.

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.

How do I program the panel/network?

Once the luminaires are installed and powered up, the system can be commissioned.  With simple small installations, a panel can be up and running very quickly by using the key pad to allocate the emergency lights descriptive text and auto learn them on to the system.  The process is accelerated thanks to the fact that the panels come ready configured with a default testing schedule that meets all requirements of BS EN 5266 code of practice.

There is also a Config Tool software package which can be used to configure the system, and is useful on larger installations.  The Config Tool also has the added benefit of enabling you to save a backup of your system configuration, should you need to reset the system at some point in the future.

Can I network Lux Intelligent panels?

Yes, Lux Intelligent panels can be quite easily networked by two core cables and the addition of easily installed networking cards to each panel.  The network can be a simple radial connection, or as a loop to introduce additional security of performance of the network.  The choice of network is governed by which network cards are installed.

The panels can also be connected to a LAN via the Serial to Ethernet LAN device.  For more information see What are the advantages of using a LAN device to network my panels?
