Connection of Temperature Sensors
The wired temperature sensor is connected to the “Reader” terminal group. The black and red wires coming from
the sensor shall be twisted together and connected to the “GND” terminal, and the yellow wire to the “DATA”
terminal - as shown in the picture below. If it is necessary to connect several wired temperature sensors, then all
of them shall be connected in parallel to each other.
In order for the device to detect a wired temperature sensor, it is necessary to turn on the mode of constant polling
of the 1-Wire interface in the device settings. It is possible to do this on the “Miscellaneous” tab in the
section.

It is possible to connect a wired sensor to the wireless temperature sensor CN-Celsius.

Connection of Expander “EW-12”
“EW-12” is an expander of the wired zones for the “Nord GSM” control panels, with its help it is possible to
increase the number of zones up to 16 or the number of outputs of the “open collector” type.
