10 - CONNECTION
This chapter explains how to connect the detection loop, the sirens and the Master Bus.
N.B.
All detectors and modules connectable on the loop are equipped with a dual loop isolator (inbound and outbound),
in compliance with the standard EN 54-2 which provides for an isolator at least every 32 devices.

Fire control panel
On the detection loop of the control panel it is possible to connect up to 199 detectors and up to 99 modules.
The detection loop can be connected in open or closed loop mode. In open loop mode, pursuant to the standard EN 54, it is
possible to connect a total of 32 devices (detectors or modules) on each branch of the detection loop.
For loop connection, we recommend to use a shielded 2-poles twisted-pair cable with
fl
exible conductors, whose minimum section
required is 0.5mm².
For reasons of electrical safety, the shieldings of the cables must be connected in order not to stop their path and must be
grounded inside the casing of the control panel.
The maximum length allowed for the laying of the detection loop is 3000 meters, as de
fi
ned by the low voltage directive
LVD 2006/95/EU.
