CONNECTION TERMINAL BOARD AND INPUT/OUTPUT DESCRIPTION
Find here below the terminal numbers and their description:
Description of Inputs/outputs
The
IN1
and
IN2
inputs may operate in two different modes selectable through JP2.
1) JP2 inserted in the right position (as shown in the wiring diagrams):
in this case the inputs
are balanced, they operate on a resistance-change basis. The balancing resistance provided,
to be connected to the inputs, must be 47 Kohm. Diagram 1 shows the connection to devices
having output NC contacts, which are necessary for the dialler operation. When the contact is
closed, the dialler is at rest, when it is open the dialler starts the calling cycle.
2) JP2 inserted in the left position:
in this case the inputs are not provided with positive. This
means that the dialler is at rest when positive is present (+12). Without positive, the alarm cycle
will start.
IN1
and
IN2
are the inputs of channel 1 and channel 2 respectively. When they are unbalanced,
they start their calling cycle.
IN/BL
is the block control input; if it has not started yet, it excludes the calling cycle related to
channel 2 whereas, if it is still in process, it will stop it. It can be connected directly to the control
panel TC terminal, in this case the dialler channel 2 which is normally dedicated to burglar
systems, will be stopped as soon as the control panel is disconnected and will be on as soon as
the control panel is connected.
Open collector-type
C/BAT output,
gives the signal of low backup battery and/or GSM battery. It
remains with potential 0 during all the time the battery in the low condition.
