CHAPTER 3 – Installing
Connecting Sensor Alarm to Zones
Connecting N.C. / N.O. (Simple contact)
Direct connection of the alarm sensor to a zone of the plant, allowing the discrimination of
two distinct states by zone:
• rest
• alarm
In this case, if the sensor were equipped with them, we recommend the use of the area
"24h" to detect the status of the outputs tamper or darkening.
Resistors used for balancing:
The official resistors provided directly by the parent company are of 3 types: 10k, 3K9,
6k8;
You can recognize them by the color code from diagrams:
However, the system allows manual configuration of real values of line resistance in three
basic states: alarm, tamper and anti-blinding; doing so for example you can replace
existing plants with its own balancing configurations simply by measuring
with a multimeter the resistance of the line in the states listed above and
report values in the appropriate fields through software or keyboard.
Single Balancing:
Connecting the alarm output of the sensor to a zone of Control Unit aided
by a resistance 3k9
Ω
that allows the discrimination of three states:
• rest
• alarm
• sabotage (only short)
