5.2 Overall dimensions
Figure 2 - Overall dimensions of the detector with a mounting bracket
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 IR sensor, when a flame is detected, converts 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. 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 330-4-1 «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.
FD 330-4-1 «VEGA»is resistant to false alarm. It doesn’t respond to visual disturbance
sources other than flame, such as electric welding, artificial lighting, sunlight, lightning, high
voltage arc, X-rays and gamma rays, etc.

7. Mounting
7.1 Mounting location
For the correct mounting of the detector, the following factors must be taken into
account:
The location of the detectors must ensure unobstructed control of the entire
protected area;
While detector’s positioning and targeting take into account the distance of
action and the viewing angle of the device;
Notice: Recognized that FD 330-4-1 «VEGA»has the highest sensitivity along
the central axis, which should be oriented to the place of a possible fire (Figure
1);
Wrong orientation of the detector
Correct orientation of the detector
Figure 3 –Installation relative to the horizon.
It is necessary to visually estimate the area (viewing angle) controlled by the
detector. To do this, you can use the viewing angle indicator, which simplifies
the process of orienting the sensors while mounting in the field.
While mounting the detector should be oriented in such a way as to avoid direct
illumination from radiation powerful sources (sun, projector, etc.)
If there is a danger of mechanical damage to the detector, a protective structure
must be provided that does not intervene its performance and fire detection
efficiency;

Availability of a sufficient number of detectors to protect the controlled area;
The detector must be mounted on a rigid surface that is not subject to vibrations;
The detector must be easily accessible for periodic maintenance service;
While mounting take measures to prevent moisture from getting into the
electrical connections or components of the detector. Ensuring moisture
protection is necessary to keep the device in operation.
7.2 Preparation
Before FD 330-4-1 «VEGA»mounting a visual inspection is carried out. It needs to pay
attention to:
1) FD 330-4-1 «VEGA»ex-marking and a warning label;
2) zero damages;
3) presence of all the fasteners (bolts, nuts, washers) in accordance with FD 330-4-
1 «VEGA»site placement project;
4) presence and integrity of the connecting wires (coming out of FD 330-4-1 «VEGA»
insulation;
5) presence and integrity of the seal on the housing of FD 330-4-1 «VEGA».
6) It is recommended to connect FD 330-4-1 «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 330-4-1 «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) Removable parts should fit as closely to the housing as possible.
9) The cable sealing on the cable gland must be carried out in every manner, since
the explosion-resistance of the input converter depends of this.
10) The external grounding conductor must be carefully stripped, and its connection
to the grounding clamp must be protected from corrosion by applying grease.
11) 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 330-4-1 «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 330-4-1 «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 330-4-1 «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 check whether the LED
indicator on the FD 330-4-1 «VEGA» front is illuminated with constant yellow light for 3
seconds. After 3 seconds, the LED indicator lights up with a flashing yellow light for 7-8
seconds, after which the detector self-test begins (three test lamps flash three times), then at
the end of the initial test –a continuous glow of green.
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 330-4-
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 330-4-1 «VEGA» consumption.
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.

MRBP.425241.001-01 UM version 1.1 01.05.2022 FD 330-4-1 «Vega»

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 330-4-1 «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 330-4-1 «VEGA» = 150 mA N(pcs.)
