Description
This interface gives the possibility of connecting the alarm system to a sensor line (that
can be balanced with resistance, and/or which intervention can be delayed) requiring
12 V power supply.
Produced in the basic modular version, the device can be used when centralizing all the
interfaces in junction boxes. A LED on the device confirms the appropriate operation
of the same during the system test procedure, and the tripping of the burglar-alarm
system, when the system is armed.
Power supply from SCS BUS: 27 Vdc
Max. absorption: 5 mA to which the absorption of the sensor
connected must be added
Operating temperature: 5 – 40 °C
Output: 12 V Max 50 mA
Technical data
Size: 2 Basic modules
Dimensional data
The interface requires the allocation of the zone Z it belongs to, of the N progressive
number of the sensors within the same zone, and the setting of the MOD contact line
protection mode.
Z1
This congurator assigns the number of the assigned zone of the NC magnetic contact
connected to line 1.
N1
This congurator assigns the progressive number of the NC magnetic contact within the
zone determined in position Z1.
MOD
In this position a congurator is inserted for selecting the operating mode of the
interface according to the type of contact or detector connected to the line. It is possible
to create a balanced and unbalanced protection line, with the possibility of generating
the alarm with a delay, as for zone 1. For the details of the various operating modes, refer
to the table below.
