4.2.2
Inputs connection and configuration
To inputs can be connected magnetic contacts, presence detectors, rolling shutters detectors,
technological detectors and emergency detectors, with the following exceptions
:
•
To input 1 can not be connected rolling shutters or technological detectors
.
•
The burglar input 1 is the only delayed, all the other burglar inputs are immediate (for further details,
see paragraph
5.4.2
Main programming menu
).
•
The tamper input (SAB) is always active (H24); it is an immediate input.
Inputs and tamper line can be configured as normally closed (NC) or balanced (single balancing). For
balanced lines are used 2.7 kohm resistors, tolerance 1% (provided).
Figure 23 –
Inputs connection diagrams
The balanced connection allows to detect short circuits attempts on the detectors lines, causing an alarm.
The selection of connection mode is made with the jumper JP1 on the motherboard.
Closed JP1
Lines and SAB input balanced
Open JP1
Lines and SAB input normally closed (NC)
(Factory setting)
WARNING
: The configuration is valid for all the lines; it is not possible to have some inputs or the
tamper line configured as balanced and other ones normally closed.
