Below is the connection diagram for the four bus wires to the devices:
1.1.3 INPUT AND OUTPUT ARRANGEMENT
The individual system detectors are physically connected to
inputs
. One or several detectors may be properly
connected to each input (if several detectors - to be connected in series - are available, you will not be able to
identify the device that triggered the alarm). Yet, one single detector cannot be connected to several inputs.
The inputs may also be associated to predefined
sectors
, numbered 1 through 8. Each input may be associated to
one or several sectors: one input associated to several sectors will signal an alarm even though only one of the
associated sectors is ON. The sector is used to group all the inputs that perform the same task, in order to allow
such inputs to be controlled (the sectors - not the inputs - are switched ON and OFF). Let us consider a company,
by way of example: all the raw material warehouse inputs may be associated to a sector; the finished product
warehouse inputs may be associated to another sector; the manufacturing department inputs may be associated to
one further sector; and the office inputs may be associated to one additional fourth sector. By extending a similar
example to a residential building, the apartments may be associated to a sector, and the garage may be associated
to another sector.
Finally, another possible macro-group is available: the
area
, which makes it possible to group one or several
sectors and further facilitate system control. Three predefined areas (A, B and C) are available, which cannot be
renamed. In the company example above, the two warehouses and the manufacturing department may be grouped
within one single area, in order to be able to actuate the antitheft feature by means of one single command at the
end of the working day.
To sum it up:
•
the
inputs
shall be associated to the sectors; they cannot be associated directly to the areas;
•
one input may be freely associated to one or several sectors;
•
8 predefined sectors are available (numbered 1 through 8);
•
a number of inputs ranging from 0 to the total of the inputs available in the system may be associated to every
single sector;
•
the sectors may be associated to the areas (each sector may belong to several areas);
•
3 predefined areas are available (A, B and C).
The actuating devices (sirens, blinkers, solenoid valves, presence lights etc.) are connected to the outputs. The
outputs may be associated to the inputs, sectors and areas.
