How to Install Smartbus 4 Zone Dry Input Moudle

Introduction:
The S-BUS G4 4Z Module is the bridge device between the S-BUS network and the Dry
contact environment. Where it reads the information from any Dry-Contact device and by
configuration and programming can act upon the readings.
The 4Z module is installed to the S-BUS network like any other device.

Various of sensors for may of purposes in the market with the dry contact Nature. They can be connected to the 4Z DRY INPUT ports as shown in the picture on the right.
Z1, Z2, Z3, Z4 are the zone ports where the sensors first wire should be connected, and the second wire should be connected to the COM port which common to all zones.

 

Connecting multiple sensors to one Zone:
The diagram on the right shows multiple
Sensors connected in series to only one zone.
Depending on the application required, by connecting the
Sensors in series means that all the sensors have to be CLOSED
In order for the 4Z to read it as CLOSED, and only one OPEN
Would cause the reading to be OPEN.
 

Connecting in parallel means that if any of the sensors
Went CLOSED the reading will be CLOSED while all Sensors have
To OPEN in order for the reading to be OPEN.
 

Like the famous logic relations AND, OR where the In Series represent AND and in Parallel represent OR.
