Box contents
The control panel is contained in a box. See the
contents below:
•A sheet metal cabinet and plastic door with an
assembled motherboard and power supply switching.
•The Quick-Start Setup Guide.
•A transparent plastic bag containing a USB consisting
of installation manuals, user manuals, and the FireClass
software console to manage the panel, the KST thermal
probe, two 3.9 kOhm resistors, a 320 mm red and a
black cable with a faston terminal to connect batteries
with main board, and a 320 mm black cable with two
faston terminals to connect batteries.
Proceed carefully to unpack the contents and dispose
of recyclable materials in accordance with local laws.
Cable requirements
All cables should be specified and installed to meet the
requirements of local laws. See Figure: 1 for a typical
system layout.
Cable types
For specific details on the cable types, and how they
should be run, refer to local practices and regulation.
Earthing
The addressable loop conductors must be isolated
from the earth. Any current leakage to the earth is
indicated as a fault.
Screening
If a cable with a conductive screen or a metal sheath is
used, do not connect it to the addressable loop
conductors. Join the screens from each section of the
cable within each loop device to form a continuous
cable screen.
Cable routing
Ensure cables are routed to minimize coupling effects.
Avoid grouping power and signal cables together in the
same conduit or trunking. Feed the mains supply into
the cabinet through its own dedicated knockout.
RS485 networking
Use copper cabling for the network. The maximum
distance between nodes is 1000 m using a shielded
twisted pair cable. Use shielded cables only, with one
end of the shield connected to the control panel
negative terminal and one end of the shield left free.
The continuity between several segments of
connection must be secured.
Mains supply
Do not allow the power cable to cross over other
wiring. The power cable must be routed and held firmly
in place by a two cable tie. The mains supply final
circuits to all parts of the fire alarm system should be
dedicated solely to the fire alarm system, and should
serve no other systems or equipment.
To facilitate local isolation during maintenance,
suitable means should be provided for double pole
isolation of the low voltage supply circuit that serves
the power supply and control equipment.
The power circuits of this control panel comply with the
EN54-4 standard.
CAUTION
In order to comply with the safety
regulations in force, the mains must be
equipped with a bipolar isolating device
for protection against over voltage and
short-circuit to earth.
The control panel is powered from the mains (230 V~
60/50 Hz -15/+10%) and provides housing for a 5.5 A
switching power supply (BAQ140T24).
