3Product description
The gas detection control panel is suitable for applications that place increased demands on the complexity of the system. Up
to 100/200 transmitters of toxic and explosive gases can be connected to the control panel using 8 independent digital buses
(BUS). If higher system reliability is required, these buses can be combined and connected in a ring topology (LOOP).
The control panel has 20 output programmable relays. Each of these relays can be freely selected to 4 levels of detection, PEL
and fault from each transmitter.
The control panel has an integrated DIN rail inside the box with the possibility of adding other components such as relays,
auxiliary sources, etc.
If analog transmitters are required, they can be connected via a 4-20mA analog input card with HART support and a card with
output relays.
The control panel has an optional LTE modem with connection to the DegaCloud service for remote management and
visualization via the internet.
The graphic display allows clear visualization of the detection status, viewing the alarm history, and also the complete settings
of the control panel without the need to use a PC.

4Construction
Prior to mounting, read the valid installation standards ČSN EN 60079-29-2 (Selection, installation, use and maintenance of
flammable gas and oxygen detectors) and ČSN EN 45544-4 (Instructions for selection, installation, use and maintenance of
toxic substance detectors).
In explosive areas, the electrical installation must be carried out in accordance with the ČSN EN 60079-14 standard (electrical
installation in hazardous areas).

Secure with a key
Drilling holes for bushings
There are 28 holes for the PG11 bushing and 4 holes for the PG21 bushing in the control panel box. Take extra care when drilling
holes to avoid damaging the internal electronics.
Drill the required number of holes with a drill
with the required diameter according to the
bushings used.
When drilling, pay attention to damage to the
electronics.

15
Install bushings
Note: The bushings must be carefully tightened after cable installation. This is the only way to ensure IP protection according to
these instructions.
Selection of supply voltage and maximum current load
4.3.1 Supply voltage 100-230V AC
The maximum current load of the control panel is 6300 mA (maximum source load). This current is used to power the
connected transmitters and the optical and sound signals, which are connected to the "LIGHT_SIG" and "SOUND_SIG"
terminals. The maximum load of these terminals is 5 A. The outputs are protected by a 5A-T tubular fuse.
Example: we have connected 20 transmitters with a consumption of 60 mA, for powering optical and sound signaling we have 5100 mA (I =
6300-20x60)
4.3.2 Supply voltage 24V DC
Consumption of control panel electronics is 300 mA. The maximum current at the "+24V DC" terminals is 6300 mA, which are
protected by a 6.3A-T tubular fuse. The maximum load of the control panel is calculated as in the previous case
Information on the consumption of individual transmitters and components of optical and sound signaling is provided in the
relevant manuals.
Warning: Never connect 24V and 230V power supply at the same time.
Uninterruptible power supply UPS
In this case, the control panel is powered by 24V from a backup source. Connect the control signals from the backup source
according to Figure 4 Connection of backup power supply and control panel. Dimension the wires according to the current
consumption of the control panel. See 7.3.2 Supply voltage 24V DC.

Figure 4 Connection of backup power supply and control panel

17
Connection of transmitters via RS485 bus
The transmitters can be connected to the control panel via a digital RS485 bus. The control panel has 8 independent RS485
lines. All transmitters can be connected to one line, but it is recommended to balance the transmitters on multiple lines due to
power loss on the wires.
It is possible to use two ways of connection:
1) Bus topology (BUS) - transmitters are connected to the bus, which is connected to one line on the control panel. Up to
8 independent buses can be created. The control panel can be connected anywhere on the bus. If the cable is
interrupted, communication with all transmitters located behind this interruption will be lost.
Figure 5 Bus topology
2) Circular topology (LOOP) - the beginning of the bus is on the control panel (BUS0 or BUS2) and the connected
transmitters follow. The bus termination is again on the control panel in BUS1 or BUS2). Therefore, 2 independent
circuits (BUS0-BUS1 and BUS2-BUS3) are used. The advantage of this solution is that in the event of a cable break in
one place, there will be no loss of communication with any transmitter.

18
Figure 6 Circular topology
Figure 7 Cable break between transmitter 2 and 3. Communication has broken down into 2 independent BUSes. No
communication was lost.
4.5.1 Cabling installation for RS485
The cabling must be suitably dimensioned to prevent excessive voltage drops on the bus. It is recommended that for 32
transmitters on the bus/ring, the maximum distance between the control panel and the last transmitter is 500 m. For 16
transmitters, this length is then doubled.
In the Czech Republic, the control panel is approved for use only with Prakab PraFlaGuard 2x2x0.8 cables. In other countries,
any cables of a similar type can be used.

Figure 9 Termination resistor
According to the RS485 specification, the last device on the bus must be
terminated with a 120R terminating resistor. If the control panel is the last
element of the bus, install a jumper on both pins. There is a separate
termination resistor for each bus, which is located below the terminal
block of the respective bus.
Connection of transmitters using 4-20 mA
If it is required to connect transmitters to the control panel using 4-20 mA, it is necessary to use DEGA UDA AI8 expansion
modules. Up to 8 transmitters can be connected to each module. The maximum number of modules is 25 pcs.

Note: The outputs are protected by a 5A-T tubular fuse.
Output relay
Each relay can be configured to activate the following arbitrary number and combination of events:
4 levels of gas leak alarm, PEL, STEL, transmitter failure, and control panel signal states.
After activation, the relay can have the following output functions configured: idle on, idle on, cycling on/off, automatic
deactivation of outputs after a certain time, or after pressing a button.
The specific configuration of the relay can be found in the configuration protocol supplied with the control panel.
RS485 Host connection
This interface is used to transfer process data using the MODBUS protocol. It must be enabled in the settings menu. See
chapter 9.11.1. The interface is galvanically separated from the rest of the control panel and should be connected to the
superior system in 3 wires using data signals A and B and a common GND wire.
If the control panel is the last element on the bus, it should be terminated with a termination resistor - shorted jumper JP6.
