NFS Supra

4.4.4 Auxiliary 24V Outputs

NFS Supra control panels have two 24 Vdc outputs, supplied from the control panel
power supply.
Max. Power from each output is 500mA at 24Vdc, protected by electronic resettable fuse.
24 V AUX fixed output provides 24V non-resettable from mains supply or batteries.
Resettable 24VAux.: Voltage goes down to 0V for approx. 5 seconds, each time the
control panel is reset. This output is used to supply external devices that need to cut
the power supply to be reset.
Before connecting any external current to the control panel, check the max. current allowed for
the devices that are going to be connected.
Please, consider the time that the system must remain in standby and in alarm.
Make sure that the control panel power supply and batteries have enough power.
Otherwise, auxiliary devices must not be supplied by the control panel but by suitable
external power supplies.
For calculations, check the technical specifications of this manual and the manual of each
devices you want to connect.
Please, refer to the diagram, on the previous page, to connect coils, relays or valves.
Otherwise, the control panel may become seriously damaged.
CAUTION! Battery backup period time reduction
The external consumption in Standby and Alarm means a direct reduction of the
capacity of the batteries to keep the system during an emergency.
Do not connect high consumption external equipments to Aux. 24 Vdc Outputs. Instead, use
the auxiliary power supplies.
