In installations with potential radio frequency interference, the use of a twisted, screened
cable is recommended. Connect the cable screen to the cable adapter and ensure that
the installation is properly connected to earth.
2.2.1 Mains power connection
Figure 7: Location of bipolar magneto-thermal switch
1. Bipolar magneto-thermal switch
For safety, the sequence in which the connections are made must be:
1. Mains
2. Batteries.
The fire panel has two power supply systems: the main supply and the batteries.
Connecting to the mains supply
For optimum fixation of the mains cable, use pressure-sensitive clamps on the housing.
2.2.2 Mains fuse
The fire panel may be powered from either 230 VAC or 110 VAC. Place the mains fuse in
its proper position (see Figure 8 Mains power connection).
See section 6 Technical specifications for fuse characteristics.
Do not use the mains fuse for connecting and disconnecting the fire panel from the
mains; use the magneto-thermal switch.
FP400 Series Installation Manual
Do not make any connections with the power supply on. Disconnect the
external magneto-thermal switch.
The fire panel must be connected to the main supply through a bipolar
magneto-thermal switch. An adequate ground connection is required. It is
recommended that the ground cable is longer than the rest so that, in case of
sudden pulling, it is the last cable to be disconnected.
To power from 110 VAC place the fuse in the left fuse holder.
To power from 230 VAC place the fuse in the right fuse holder.
