5.3 Construction
The detector housing is a flameproof enclosure, inside which all detector devices are
located, including sensitive elements that convert the electromagnetic radiation of the flame
into an electrical signal, electronic amplifiers and filters, digital-to-analog converters, a
microprocessor, display elements, optical elements for checking the operability of channels.
5.4 Principle of operation
The UV and IR sensors, when a flame is detected, convert electromagnetic radiation into
an electrical signal. Signals in digital form are processed in the microcontroller according to a
given algorithm to increase the reliability of the alarm output. The program highlights the
useful signal from the background, checks the correlation degree between UV and IR
channels. As a result of signal processing, a decision is made on the formation of output
signals: analog current output 4.20 mA, digital output in RS-485 standard with Modbus RTU
interface, “FIRE” relay contacts, “FAILURE” relay contacts.
FD 329/330-3-1 «VEGA» detector is equipped with a special self-testing function, that
performs correct operation check automatically every 30 minutes. It does not require the use
of an external control source of radiation (test lamp). Successful completion of the automatic
check does not cause the detector to switch to the ‘‘Fire” mode.

4) presence and integrity of the connecting wires (coming out of FD 329/330-3-1
«VEGA» insulation;
5) presence and integrity of the seal on the housing of FD 329/330-3-1 «VEGA».
6) It is recommended to connect FD 329/330-3-1 «VEGA» analogue outputs located
in the hazardous area with an external device located in the non-explosive area using a
control armored cable of the КВБбШв4х1,5 brand according to GOST 1508-78. The
КВБбШв cable can be used in hazardous areas of any class, including indoors, outdoors, in
channels, tunnels, ground (trench) in an aggressive environment, in places exposed to stray
currents.
7) While FD 329/330-3-1 «VEGA» mounting it is necessary to check the condition of
the ex-proof parts subjected to disassembly for compliance with the requirements of the EX
protection drawing (appendix B).
8) Check the availability of cable gland seals and plugs.
9) The external grounding conductor must be carefully stripped, and its connection
to the grounding clamp must be protected from corrosion by applying grease.
10) Upon mounting completion, the grounding device resistance must be checked
and must not exceed 4 Ohm.
7.3 Cable requirements. Cable gland
It is recommended to connect FD 329/330-3-1 «VEGA» analogue outputs located in
the hazardous area with an external device located in the non-explosive area using a
control armored cable of the КВБбШв4х1,5 brand according to GOST 1508-78. The
КВБбШв cable can be used in hazardous areas of any class, including indoors, outdoors,
in channels, tunnels, ground (trench) in an aggressive environment, in places exposed to
stray currents.
Use certified cable glands M20 while mounting.
The cable sealing on the cable gland must be carried out in every manner, since the
explosion-resistance of the entry compartment depends of this.
Notice: If it is necessary to connect piping to a cable gland with a ¾’ NPT thread, the
connection is made using a transitional threaded sleeve:

8. Detector connection
8.1 Power source requirements
Before connection it is necessary to:
- Calculate the total power consumption rate of the gas detection system in watts,
taking into account cold start.
- Select a power source with the appropriate power for the calculated load.
- Make sure the selected power source provides a regulated 24 VDC output voltage
for the entire system, taking into account allowable ripples. It is recommended to use
of a battery backup power supply to improve system reliability.
Notice: If it is required to be able to turn off the power supply, then a separate method
of turning it off must be provided.
8.2 Detector connection
To connect the detector:
-fix the mounting bracket at the FD 329/330-3-1 «VEGA» workplace, install a base on
it and fix it with a screw and a lock nut. The detector with a mounting bracket and its overall
dimensions are shown in figure 2;
-separate the base with cable gland from the detector housing;
-install the connecting cable in the cable gland исоединить проводники с
соответствующими клеммами,and connect the conductors to the corresponding terminals
located on the backplane:
Figures 4 and 5 show examples of connecting the detector to fire alarm control panels;
Figures 6 and 7 show diagrams of connecting the detector to fire alarm control panels
in the analogue signal using and digital output using mode;
Figures 8 and 9 show diagrams of connecting two detectors to fire alarm control system
via RS-485 interface with and w/o terminal box;
-install the FD 329/330-3-1 «VEGA» housing on the base and tighten the 3 screws;
-turn the detector for correct targeting;
-after applying power to the detector, it is necessary to control the internal IR and UV
radiation test sources, powered by a pulsed voltage. This radiation falls on the optical
sensitive elements of the IR channels (IR channel test lamp blinking at a frequency of 4-5
hertz for 1.5-2 seconds) and the UV channel (UV channel test lamp lighting once for 0.5
seconds), which allows the FD 329/330-3-1 «VEGA» to carry out a self-test every 30 minutes.
After successful passing of the test, at the FD 329/330-3-1 «VEGA» output a «slow»
alternate red LEDs blinking appears in the window of the FD 329/330-3-1 FD 329/330-3-1
«VEGA» IR channel, which corresponds to the detector entering «Standard»mode.
Detector connection to RS-485 digital channel
1. It is recommended to connect the detectors to the bus via a terminal box. Detectors
connection to a terminal box is carried out by a cable with a recommended length of
not more than 0,5m. Cable must meet the cable gland requirements on the FD
329/330-3-1 «VEGA» housing and terminal box. For the connection from terminal box
to the bus an armored cable with pairs of shielded twisted pairs can be used.
2. For the correct power supply network organization note that the supply voltage at the
terminals of the devices must be not less than 18 V and not more than 32 V, taking
into account the FD 329/330-3-1 «VEGA» consumption.

MRBP.425241.001 UM version 1.1 01.05.2022 FD 329/330-3-1 «Vega»
14
3. The information network organization must be carried out in a way that the voltage drop
on the –24 V wire between the central processor and the detector does not exceed 8
V.
4. It is recommended to connect the detectors in a branch line from the main interface line.
Branches should be formed by installing repeater-splitters with galvanic isolation of the
type at the nodal points of the line. Each branch must serve a separate tank. Extension
of the main line beyond 1200 m must be carried out by inserting an interface repeater into
the line.
5. It is advisable to power the FD 329/330-3-1 «VEGA» according to the beam scheme -
each tank has its own cable.
Allowable line length is determined by the formula:
L(km) = 25 ΔU(V) S (mm2) / Imax(mA),
where ΔU(V) –allowable line voltage drop;
Imax(mA) –max current consumption;
(Imax(mA)FD 329/330-3-1 «VEGA» = 150 mA N(pcs.)
