6.1 'POWER' connector strip
The 'POWER' connector is only needed if the supply is not possible via the MoNetBus
or PoE. This is generally only the case if the Ethernet switch (modular) is installed
remotely in another device. The power supply must be a DC 24 V power supply
featuring regulated and power-limited output that has been approved for fire alarm
signal applications.
