The electric outputs U2 and U3 can be individually configured as “positive reference” or “negative reference” via the JP2,
and JP3 jumpers. The default configuration of the outputs is
“Negative Reference”.
The electric outputs can be transformed into relay outputs
– See Paragraph
5.12.6.1 .
For details on connections (power supplies, inputs, outputs, bus, etc. …) see paragraph 5.12.2
Connecting the data Bus
and paragraphs 5.12.5 Connecting inputs and 5.12.6 Connecting outputs .
The expansion is always powered by the control panel via the bus connected to the M1 terminals. The power supply for
the detectors and the signalling devices connected to the M2 / M3 / M4 terminal boards always arrives from the control
panel.
The expansion section also controls the functioning of the secondary bus. If an attempted tampering should be detected
or merely a malfunction should be detected, disconnect the secondary bus to prevent compromising the functioning of
the entire system.
The 1067/032A or 1067/052A control panels receive information on the functioning of the supplementary power supply
from the expansion: black out, battery low, and power supply breakdown.
5.11.3.2 The Repeater
The Repeater circuit regenerates the data and provide power for the extension of the new length of Bus for the control panel
(drawn from the power supply and the local battery). By referring to the
Figure 54 - 1067/092 Board , the functions of the
terminals and LEDs dedicated to the Repeater are the following:

The BUS OUT terminal board is used to connect the various devices to the new length of the Bus. The signals coming from
the Bus of the control panel are repeated to be transported a long distance, with the 1067/032A and 1067/052A control
panels having complete control.
The Repeater section is irreversibly linked to the power supply section
“P”,
which also provides it with power. Therefore,
in case of a blackout or absence of the back-up battery, it will not be possible to reproduce the data on the Bus
(essentially the extension of the bus is lost together with all the devices that are connected to it).
