Tamper input
The keypad is provided with an auxiliary input and a tamper input. Both the inputs are locally managed by
the keypad; an alarm, if present, is sent to the control panel via bus.
4.3.1 Auxiliary
input
The auxiliary input is unbalanced (terminal pins In and –RV). The input is configured by default as
“contact”, for example for a magnetic contact on a door, but it can also be configured to connect a rolling
shutter detector.
WARNING
:
•
Auxiliary inputs are always associated to the zone A.
•
The auxiliary input generates only a generic burglar alarm, that can not be punctually located with
dedicated Led.
4.3.2 Tamper
input
The keypad tamper input (terminal pins SAB and –RV) is designed for connection of the front tamper
installed on the support (for details, see paragraph
3.3
MANAGEMENT KEYPAD
).
The figure 27 shows the
connection diagram
.
Note
:
If the input IN is unused, it must be connected to ground (-RV).
