Warning devices connected directly to a relay output of the control unit

4.3.1

Warning LED displays

The control unit of the Teta Gas system can handle the following warning number of warning LED displays:

18 units for the power voltage of 24 V,
9 units for the power voltage of 48 V,
30 units for the power voltage of 230 V.

When the system includes more warning LED displays than the foregoing limits, an additional relay with
elevated immunity to voltage surges (appearing at the moment of a warning board activation) must be

applied. Current carrying capacity of the relay contacts must be properly selected to match consumption of
electric current by all warning LED displays altogether with sufficient safety overhead. The connection

diagram with the use of an additional relay is shown in Figure 8.
The manufacturer recommends the RPI-1ZI-U24A relay from Relpol with the output current sufficient to
connect:

50 warning LED displays for the power voltage of 24 V,
100 warning LED displays for the power voltage of 48 V,
100 warning LED displays for the power voltage of 230 V.

4.3.2

Alpa SZOAmini Warning Beacons

Up to 16 warning beacons of the Alpa SZOAmini type with the power voltage of 24 V can be connected

directly to the control unit of the Teta Gas System.

4.4

Connection of warning devices via the Teta Bus interface 

Up to 12 warning devices with the Teta interface can be connected to a single control unit of the Teta Gaz
system.

4.5

Solenoid valve

The valve can be connected in two manners:

directly to the Control Unit Module Teta MOD Control 1 – see Figure 6 – which enables connection

of a single valve with the power supply voltage of 230 V or 12 V, 
by means of the Control V Valve Controller – extends the system capacity to connect up to 8 valves

with the power supply voltage of 12 V. 

Incorporation of the Control V controller also enhances the system automatic troubleshooting since the
controller monitors continuity (resistance) of the valve control line, status of the battery charging and

fluctuations of the power supply voltage with indication of the need to check the valve and to run a manual
test. 

4.6

Teta MOD F

For facilities where the level of interferences exceeds thresholds specified in the Directive 2014/30/EU (on

the harmonisation of the laws of the Member States relating to electromagnetic compatibility) application
of the Teta MOD F Control Unit Module is strictly recommended. 
The connection between Teta MOD F module and the control unit is shown in the schematic diagram below.
