Shielded cable
When using a shielded cable, you have to pay attention to the following important notes:
The shield must be connected to the fire detection control panel
only at one end
of the loop.
The shield has to be securely connected through in each detector base or module. The shield must
not be interrupted in any way.
If no shield terminal is available, the secure through-connection of the shield must be ensured by
means of an auxiliary terminal.
When shielded cables are installed, the use of the detector base FI700/BD is recommended. The shield
must not, under any circumstances, get in contact with any other wire or metal part.
Note the different connection of the loop to the detector base FI700/BD in comparison with the stand-
ard base FI700/B.
The terminal „R+“ of the detector base FI700/BD is used for connecting the shield.
