Connection Cables - Tecnoalarm Tecnofire TFA1-298 Installation Manual

The casing of the control panel must be fi xed in a position that guarantees adequate protection from accidental shocks and at
a height that grants full access to the operator. Consider the space necessary for fully opening the casing door (approx. 60cm).
Fix the casing horizontally on a solid surface using 4 dowels with 8mm diameter.
General warnings
For the safety of the operators protect the control panel, as any electronic device, against splashes and avoid placing recipients
containing liquids next to it. The control panel must be installed so as to ensure adequate ventilation. Do not cover the device with
things that may hinder correct heat dissipation.
Install the control panel at an adequate distance from heat sources (e.g. radiators) and any device that may cause electromagnetic
disturbances (e.g. radio antennas).

The cables to be used for the connections are defi ned by standards and installation regulations.
These are fl ame retardant, low smoke emission and halogen free cables.
The European standards specify the cables to be used for the construction of fi re detection systems.
Among these standards we mention (non-exhaustive list):
EN 50200, EN 60228, EN 50363, EN 60332, EN 50267, IEC 60332, IEC 61034, IEC 6754.
The installer shall ascertain the current legislative requirements for his country.
For all the connections on the loop, it is recommended to use shielded multipolar twisted-pair cables with fl exible conductors.
For selecting the loop and 24V power supply cables to be used, refer to the below table that indicates, based on the extension of
the loop, the minimum section that must be observed.
Loop extension
750 meters
1000 meters
For reasons of electrical safety, the shieldings of the cables must be connected in order not to stop their path and must be
grounded inside the casing of the control panel.
The maximum length allowed for the laying of the detection loop is 3000 meters, as defi ned by the low voltage directive
LVD 2006/95/EU.
The maximum length allowed for the RS485 bus (Master Bus) is 1000 meters. For greater distances use a fi ber optic connection
by connecting a TFSFC01 RS485-fi ber optic converter.
The relays and the electrical outputs of the control panel and its expansion devices form a SELV voltages network (EN 60950-1).
These outputs can only be connected to circuits that comply with SELV voltages.
