3.2 Wired Input: INKA and IOR
Sensors without radio interface can be supervised by connecting them to the wired inputs on INKA or
IOR. Inputs 1-3 are digital only, while inputs 4-5 can be configured as either digital or analog. Section
1.8 describes how the inputs are connected.
When a sensor connected to a wired input fulfils some predefined criteria for that input, the input is
trigged
. When an input is trigged, the actions associated to that input are performed. The configuration
in the unit determines the criteria for each input to be trigged and what actions to perform.
Suppose, for example, that a magnetic contact is mounted on a door and connected to input 1 of an
INKA. The INKA can then be configured so that input 1 is trigged each time the door is opened. The
action associated to input 1 in this case can be to send a radio alarm.
3.2.1 Digital Input
The equipment connected to a digital input works as a switch between the input and ground, see
image below. If the input is configured as
normally open
, the input is trigged each time that the switch
is closed. If the input is configured as
normally closed
, the input is trigged each time that the switch is
opened.
Now we return to the example with an INKA and a magnetic contact. Assume that the magnetic
contact is connected so that the switch closes when the door is opened. Then the input in INKA must
be configured as
normally open
for the input to trig each time that the door is opened.
The input mode of each wired input is configured by choosing a value from the list boxes
