1.0 INTRODUCTION
BHB-125 / 150 series Explosion-proof sounder/horn & beacon are designed according to EN/IEC 60079-0,
EN/IEC 60079-1 and EN/IEC 60079-31 standards. Enclosure material is Stainless Steel (BHB 125) or GRP
(BPB 150). This product 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. Users can choose from single or combination
types. The design of 3 in 1 sounder, loudspeaker and beacon is unique. According to user control system, 4
stages of alarm tones can be sent out, from less critical stage (stage 1) to the most critical stage (stage
4). 64 tones are selectable. Tone can be preset during installation. At the same time, four stages of alarm
light can also be sent out.

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 fig 1). The alignment and positions can be adjusted by loosening the two M8 screws, whi ch 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.
COMBINED UNIT
As for the combines unit it come with either one or two or three beacons and can be mounted on a vertical
surface via a stainless steel mounting plate (see fig. 2 A/B/C/D). The fixing holes on the mounting plate are
designed to fit M8 allen screw only. The diameter is 9mm. Use of stainless steel fastener is recommended by
BARTEC TECHNOR.

6.0 WIRING
General requirement
BARTEC TECHNOR recommends that all cables and cores should be fully identified (suggest using cable
from 2.0 to 2,5mm2)
Ensure that all nuts, bolts and screws are secured. Ensure that only the right and certified cable glands are
used and earthen 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 SS316L for this application
Cable Connection
The cable connection is connected with the terminal blocks in the electronic PCB assembly located in the
flameproof enclosure of the Beacon Component (for single unit, see fig. 3A), or assemble located in the
bottom unit which can be Beacon Component (for combined unit, see fig. 3B) or Push Button or Junction Box.
Cable connection should be carried out in accordance with relevant technical requirement.

Remove End Cover (Beacon Component)
Unscrew the 4 (BHB 125) or 6 (BHB 150) M5 retained hex socket head screws of the Beacon Component
(See fig. 3A/B). 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 the product 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 similar way, but operate in reverse manner as above.

8.0 SOUNDER VOLUME CONTROL
The BHB has a volume control to adjust the output volume of the sounder component. To set the required
output volume, adjust the potentiometer-VR1 on the PCB (See Fig 6). The potentiometer should be set to
fully clockwise position if maximum output volume is needed.
9.0 STATUS CHOSEN AND FLASHING FREQUENCY ADJUSTMENT
LED Beacon
The LED Beacon provides flashing and rotary status to be selected.
Use DIP Switch with 2 binary codes on the LED Beacon PCB to select flashing or rotary status (including
steady status). Adjust the Potentiometer on the LED Beacon PCB (see fig. 4) for frequency adjustment. For
fastest stage frequency, the potentiometer should be set to fully clockwise position.

10.0 CABLE GLAND
The BHB series product has cable gland entries. Only cable glands approved for Ex ‘d’ applications can be
used, which must be suitable for the type of cable being used and also meet the requirements of the Ex
‘d’ flameproof installation standard EN 60079-14.
SAFETY WARNING: If the BHB is used at high ambient temperatures, i.e. over +40ºC, then the cable entry
temperature may exceed +70ºC and therefore suitable heat resisting cable glands must be used, with a rated
service temperature of at least 95ºC.
If a high IP (Ingress Protection) rating is required, a suitable sealing washer must be fitted under the cable
gland.
When only one cable entry is used, the other one must be closed with an Ex ‘d’ flameproof blanking plug,
which must be suitably approved for the installation requirements.
