Detects and distinguishes the opening of two normally closed
contacts, alarm and jamming of the motion sensor, disposed in
series with a balanced line (on 1.8K) connected between an
input terminal and the respective negative (-V). Its ability to
distinguish derives from the adoption of a second balancing
resistor (1.8K) disposed in parallel to the first of the contacts to
be monitored and a third balancing resistor (3.3K). This
configuration makes it possible to distinguish between a state
of alarm and jamming of the motion sensor and a line sabotage
state, both in the event of cutting and short-circuit.
Detects and distinguishes the opening of two normally closed
contacts, usually relating to two different sensors, disposed in
series with a line with comparable behaviour to that of an NC
line, connected between an input terminal and the respective
negative (-V). Its ability to distinguish between the two sensors
derives from the adoption of a balancing resistor (1.8K)
disposed in parallel to the contact of the first sensor to be
monitored and a second balancing resistor (3.3K) disposed in
parallel with the contact of the second sensor to be monitored.
It is not capable of detecting a line sabotage state: in the event
of cutting it can generate an error or sabotage; in the event of a
line short-circuit it does nothing. The sabotage can only be
generically attributed to the wired line for the input to which it is
connected.
Detects and distinguishes the opening of two normally closed
contacts, usually relating to two different sensors, disposed in
series with a line with a balanced line (1K8) connected between
an input terminal and the respective negative (-V). Its ability to
distinguish between the two sensors derives from the adoption
of a balancing resistor (1.8K) disposed in parallel to the contact
of the first sensor to be monitored and a second balancing
resistor (3.3K) disposed in parallel to the contact of the second
sensor to be monitored. This configuration makes it possible to
distinguish between an alarm/electrical fault state and a line
sabotage state, both in the event of cutting and short-circuit.
The alarms are correctly recognised and assigned to the sensor
from which they originate. The sabotage, however, can only be
generically attributed to the wired line for the input to which it is
connected.

The 24-hour input must be configured as single balance with a
resistance of 1.8 KΩ. Refer to the relevant paragraph for
information about correct connection of the tamper lines (see
page 10).
To connect the telephone dialler to the telephone network
correctly, you must first locate the point at which the line enters
the house. The dialler must be connected as the first device, as
viewed from the incoming telephone line.
