LST700 SERIES FIRE ALARM PANEL
Planning the cable layout in the panel
The detector and sounder circuit cabling is classed as extra low voltage and should be segregated
away from mains voltages. Careful planning is needed to ensure this, refer to Figure 2 (below) for
guidance and important information on how to remove the panel’s knockouts. Always ensure that
if a knock-out is removed, the hole is filled with a good quality cable gland. Any unused knockouts
must be securely blanked off.
Figure 2 : Location of knockouts for cable entry and knockout removal details
Knock-outs should be removed
with a sharp tap in the rim of the
knock-out using a flat 6mm
broad-bladed screwdriver. Use of
excessive force will damage the
enclosure around the knock-out.
Do not drill any additional holes
for cable entry in this shaded area
as this is where the PCBs and
backup batteries will be located
These four
knockouts are
reserved for
incoming mains
cable only
All System wiring should be installed to meet AS1670.1 - 2004. Other national standards
of installation should be used where applicabl
e.
Cable types and limitations
Consult AS1670.1 - 2004 for detailed information on cables, wiring and other interconnections.
Note that all signal cabling
forming part of a fire alarm system must be red sheathed to avoid
confusion with other services.
Mains wiring
The requirement for the mains supply to the fire alarm panel is fixed wiring, dedicated circuit. This
should be secure from unauthorised operation and be marked
‘FIRE ALARM: DO NOT SWITCH OFF’ . The
mains supply must be exclusive to the fire panel.
