5.12.4.1 Connection of the detectors to the expansion module of the 1067/092
For the connection of the inputs of the various typologies (NC
– NO – to single/double balancing) see paragraph
5.12.5 .
IMPORTANT! Do not join the earths of the BUS IN section with those of the BUS OUT section in order to
guarantee a better immunity to RF disturbances.
If a sensor must be powered by the local power supply, because the power from the control panel is insufficient, it is
necessary to use relay devices to maintain galvanic isolation.
The diagram below illustrates how the connection must be made.
Otherwise, an 1067/008A expansion module connected to the BUS OUT can be used.
