10-4 - Potentiation of the secondary power supply
Normative references
The European standards indicate the conditions and parameters necessary to dimension the secondary power supply on the basis
of the current requirements.
The secondary power supply shall be dimensioned to ensure, in the event of main power failure, the autonomous operation of the
system. The autonomy must be equal to the sum of the times required for notifying, servicing and system recovery and in any case
must not be less than 24h. Moreover, the alarms should be transmitted with devices certi
fi
ed to EN 54-21 to one or more recipients.
On expiry of the minimum autonomy, the secondary power supply shall ensure in any case the operation of the system for at least
another 30 minutes starting from the issue of the
fi
rst alarm.
Additional power supply source
In the case where the consumption of the system exceeds the available current of the battery, it becomes necessary to connect an
additional power supply. For this purpose, the control panel is equipped with dedicated terminals for the connection of one or more
power supplies TFPS-5, compliant to EN 54-4. The operation of the TFPS-5 connected on the loop is supervised by the system
and therefore it is suf
fi
cient to connect the output of the power supply directly to the ALM AUX input of the control panel.
Connection of one additional power supply
The outputs OUT A, OUT B and OUT C of the TFPS-5 power supply must be connected in parallel and must then be connected to
the terminals 29 and 30 of the control panel.
10-5 - TFA2-596 additional power supply connection
Connection of two or more additional power supplies
The outputs of each TFPS-5 power supply must be connected in parallel. The negative voltages of the power supplies must be
connected in common, the positive voltages must be uncoupled with a Schottky diode SB1240 (12A-40V) and downstream must be
connected in common. The resulting pair of wires must be connected to the terminals 29 and 30 of the control panel.
