6.0 Wiring
General Requirement:
Moflash recommends that all cables and cores should be fully identified
(suggest using cable from 2.0 to 2.5 mm²). Ensure that all nuts, bolts and screws are secured. Ensure that
only the right and certified cable glands are used and earthed correctly. Ensure that only the right and
certified stopping plugs are used to blank off unused gland entry points. In order to maintain the IP
rating of the product, we recommend SS316 for this application.
Cable Connection:
The cable connection is connected with the terminal blocks on the electronic
PCB/
Terminal Blocks
assembly located in the flameproof enclosure of the
Beacon Component
(see picture
2). Cable connection should be carried out in accordance with relevant technical requirement.
Remove Top Cover (Beacon Component)
Unscrew the six (6) M5 retained hex socket head screws of the
Beacon Component
(see picture two).
This will release the cover from the base and allow the cover to hang on the
retaining wire strap. Before replacing the cover, check that the
flameproof joints are clean and not damaged, the gasket is
still retained in its groove.
CAUTION:
Before removing the cover, ensure the power
to beacon is isolated. Remove the four pieces of M5 socket
screws to open the cover. Twist the cover gently clockwise
and anti-clockwise, whilst pulling away from the base, until it comes off.
Replace the cover in a similar way, but operate in reverse manner as above.

7.0 Status Chosen and Flashing Frequency Adjustment
LED Beacon:
The LED beacon provides flashing and rotary status to be selected. Use
DIP Switch
with
3 binary codes on the
LED Beacon PCB
to select flashing or rotary status (including steady status),
the 3rd binary code is for high
and low frequency chosen.
LED Status Selection Switch:
1st & 2nd DIP Switch: ON=1, OFF=0;
3rd DIP Switch: HIGH=1, LOW=0,
S1/S2: ON=Connect with O/COM,
OFF=Disconnect with O/COM
1.0 Introduction:
The SB150-1 Explosion Proof sounder/beacon is certified for use and installation in Zone
1 and Zone 2 areas with gases groups of IIA, IIB, IIC and temperature classification of T4~T6. It specially
applies to Oil & Gas, Offshore Platform, Chemical, Petrochemical, Refinery and Marine Industries etc.
Enclosure material is Stainless Steel. The sounder has 4 stage alarm tones which can be sent out. 64 tones are
selectable. Users can record sounds or customize sounds into the sounder by using 5 spare tones. Tone can be
present during installation. At the same time 4 stages of alarm light can also be sent out.
2.0 Explosion Proof Labelling:
All products have a rating label with the following important information:
Product order no: eg SB1501RX05DCNNNAR (Refer to the datasheet for product order selection)

3.0 Type Approval Standard:
The SB150-1 series products have an EC Type Examination Certificate
issued by
Nemko
and have been approved to the following standards:
EN 60079-0:2012 (IEC 60079-0:2011),
EN-60079-1:2007 (IEC 60079-1:2007) and EN 60079-31:2009 (IEC 60079-31:2008)
4.0 Zones, Gas Group, Category and Temperature Classification
The SB150-1 series products have been certified Ex d IIC T4~T6. This means that the units can be installed in
locations with the following conditions:
Area Classification:
Zone 1:
Explosive gas air mixture likely to occur in normal operation.
Zone 2:
Explosive gas air mixture not likely to occur, and if it does, it
will only exist for a short time.
Gas Groupings:
Group IIA Propane Group, IIB Ethylene Group and IIC Hydrogen and Acetylene

5.0 Installation
General Requirement
: The product must be installed in accordance with the
latest issued relevant requirements in the EN60079-0 and EN60079-1 specification
or the equivalent IEC specification- Selection, Installation and Maintenance of
electrical apparatus for use in potentially explosive atmosphere. Product installation
must be carried out in accordance with any local codes that may apply and
should only be carried out by a competent electrical engineer.
Location
: The location of the unit should be made with due regard to the
area over which the beacon warning signal must be visible. The unit should
only be fixed to services that can carry the weight of the unit.
Mounting (Single Unit)
: The single unit only comes with one beacon and can be
mounted via a ‘U’ shaped stainless steel bracket. It can be done using one 12mm
diameter and two 8.5mm diameter bolt holes in the center of the bracket (see picture 1). The alignment and
positions can be adjusted by loosening the two M8 screws, which fastened the stainless steel bracket to the
sounder. The sounder should be positioned such that dust, debris or water cannot enter into the horn opening.
