The mains cable tail ends must be insulated to prevent dangerous conditions
arising in the event of accidental switching on of the mains supply .
Networking
Up to 126 panels, or passive repeaters can be networked together to operate as a
single networked system . To achieve this each panel must be fitted with a network
card (supplied at additional cost .)
When operating as a networked system all fire and fault event information is
displayed at every panel, silencing and resetting of alarms can also be carried
out from any panel on a networked system if panels are suitably configured .
Networked panels are connected using a loop topology as illustrated, or radial if
using a network booster .
Networked panels can be used as active repeaters, alternatively a low cost passive
repeater is available .
This can either be connected to a loop of an individual panel or it can be connected
to the network, via a network card .
The recommended network cable for the network connection between panels is
an enhanced Firetuf cable Manufactured by Draka cables (part number 910234 .)
Screen continuity must be maintained throughout the entire network circuit including
at each junction point . The cable should be grounded at least once per segment,
and preferably at each device . Grounding the shield at every device assists in
suppressing 50/60 Hz standing waves . The screen or drain wire of the network cable
should not be considered as a safety earth and therefore should not be connected
to terminals marked with the earth symbol, except at the panel, and should not be
insulated with green and yellow sleeving Where the network cable passes between
buildings, screen continuity should not be maintained from building to building . A
booster device must however be used irrespective of cable length and should be
fitted at a suitable point in the link between buildings . The cable screen should be
connected to the earth of one panel in each building .
