What options do I have for Networking my emergency lighting panels?

There are multiple options for networking your Lux Intelligent emergency lighting test panels, and then linking those panels to the Lux Intelligent cloud monitoring service.

The options for connection are:

  1. Direct serial connection between the Monitoring PC and the Lux Intelligent Panel
    1. Additional panels can be networked to the first main panel
  2. Connection to the Lux Intelligent Panel via a LAN Device, enabling the Monitoring PC to connect to the panel over the LAN
    1. Additional panels can be networked to the first main panel
  3. A mixture of the 2 methods above

The diagrams below give examples of these networking configurations:

Lux Intelligent Cloud Networked Example 1

Figure 1: A panel connected to a Monitoring PC using the Direct Serial Connection, and a Panel connected to the LAN using the LAN Device.  

In this configuration the Panel and PC connected using the Direct Serial Connection should be within 20 meters of each other.  The Monitoring PC will also need a connection to the LAN in order to upload the data to the Lux Intelligent cloud.

The second panel, connected via the LAN Device can be connected to by any of the PCs on the LAN.  This means that any of these PCs can be used as the monitoring PC.

Lux Intelligent Cloud Networked Example 2

Figure 2: Here 2 seperate panels are individually connected to their own Monitoring PC.   Again each Panel and Monitoring PC should be within 20 meters of each other.  And if using the Cloud Monitoring service each PC must also have a connection to the internet via a LAN.

Lux Intelligent Cloud Networked Example 3

Figure 3: In this configuration a single panel is connected to the LAN via a LAN Device, and then the additional panels are networked to the main panel.  As the main panel is connected to the LAN, any PC on the network can be the monitoring PC by installing the Logger Tool and Sync Tool software.

Lux Intelligent Cloud Networked Example 4

Figure 4: In this configuration each panel is connected to the LAN via it's own LAN Device.  This solution is the most economical for networking panels which are geographically spread, assuming that their is existing LAN cabling in the vacinity of the Panel.  The only additional costs for networking is the cost of the LAN Device, and the potential cost of installing a LAN connection point near the panel.  This is far more cost effective than running a cable between the panels in order to network the panels together as in Figure 3.

Can I access/manage a Lux Intelligent panel remotely?

Yes, there are a number methods of accessing and monitoring remote panels, if a direct connection to a PC is not available (PC more than 20 meters away).

The simplest option is to use the serial to Ethernet converter from the Lux Intelligent product range.  This allows the panel to be connected to the installations infrastructure.  This will allow access to the panel, via the Lux Intelligent logger software, from any PC on the local network.  However, through IT support, access could be provided via a portal to PCs from outside the network.  Aside from the converter, all that is required is a low cost data connection to the sites network.

A second option is to use other products from the Lux Intelligent range to provide remote access.  A standard modem card can be installed in the panel to connect to an external PSTN line, or simply an internal extension line.  The Lux Intelligent logger tool can be programmed to 'dial up' the panel in questions at specific times, and facilitate the downloading of results and panel data.

A similar result can be achieved using a GSM modem, where conventional fixed line connections may be difficult.   Again, this is another product in the Lux Intelligent range.

What cable do I need for loop/network wiring?

Lux Intelligent requires data cabling to be suitable for the nature and size of the installation.  The lower quantity of lights and shorter loops, results in a narrower (and less expensive) gauge of cable being required.  Cable types are defined by their Belden equivalents (universally referenced).

Cable (Belden spec.)  Cable Size  Voltage Rating (V)  Maximum cable run in metres (per installed PLU)      
AWG mm2 100 125 150 175 200 225 249
8762/8205 20  0.5  300        1500  1300  1100  1000 
8760/8461  18  0.8  300              1500 
8719/8471  16  1.3  600/300              1500 
                     

Similarly, a list with the choice of cables suitable for networking panels is shown below:

Manufaturer Model Cable Type
Belden 8205 Unscreened twisted pair 20 AWG (0.5mm2)
Belden 8461 Unscreened twisted pair 18 AWG (0.8mm2)
Belden 8760 Unscreened twisted pair 18 AWG (0.79mm2)
Belden 8762 Unscreened twisted pair 20 AWG (0.56mm2)
Alpha & BICC Alpha 2421 Screened twisted pair 18 AWG Type 2
BICC H8093  
Alpha & BICC Alpha 2411 Screened twisted pair 18 AWG Type 2
BICC H8091  
Belden   Screened twisted pair 20 AWG Type E buried distribution wire

 

 

How much cable can I run between networked panels?

Depending on the type of network, for a simple radial, the limit is a total length of 1.5km for the network.  With a loop type arrangement, the distance permitted between panels is 1.5km with a total network length of 20km.  Please remember that the type of network installed requires the correct networks cards in each panel.

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.
