GENERAL
BS-695 and BS-694 detectors are used to give
us a quick warning in case there is a natural gas
or LPG gas leak.
The installation must be done by a qualified
personnel. The instructions must be read first
before the installation.
Emergency actions
It is recommended that the following advice
should be given in the event of an alarm
sounding or the smell of gas even without an
alarm:
Keep calm, and carry out the following actions,
not necessarily in the order given:
- extinguish all naked flames, including
smoking material.
- turn off all gas appliances.
- do not switch on or off any electrical
equipment, including the gas detection
apparatus.
- turn off the gas supply at the gas main control
and/or ( with a LPG supply) the storage tank.
- open doors and windows to increase
ventilation;
- do not use a telephone in the building where
the presence of a gas is suspected.
If the alarm continues to operate, even after an
alarm resetting action where appropriate, and
the cause of the leak in not apparent and/or
cannot be corrected, vacate the premises and
IMMEDIATELY NOTIFY the gas supplier in
order that the installation may be tested and
made safe, and any necessary repair carried
out.
Placement
Depending on the monitored gas, the unit must
be placed 30cm from the ceiling (for methane,
natural gas) or 30cm from the floor (for propane,
butane, LPG). The horizontal distance should
not be more than 4 meters from the probable
gas leak point and the detectors must not be
placed in humid or drafty areas.
It is suggested that the detector is tested for
good operation every 6 months or if it is
changed position.
The unit must should not be sited:
- directly above cooking appliances.
- directly above sink.
- adjacent to extractor fans.
- in any outside location.
- where the environmental conditions are
outside the manufacturers operational
specification.
Installation
For the installation of the device first you must
remove the red plastic with a screwdriver as
shown in figure 1 and unscrew the screw in the
middle. Then with the help of figure 2 you can
connect the external devices.

content of gas (propane or butane), in the
monitored area, exceeds 5 - 15% of the lower
explosive level (L.E.L).
The BS-695 detectors are activated when the
content of gas (methane), in the monitored
area, exceeds 5 - 15% of the lower explosive
level (L.E.L). The same detectors can also be
used as an alcohol vapor detector.
They are connected and operate with the mains
power supply voltage of 230V AC, as shown in
figure 2.
When the detector is activated, an internal
sounder(buzzer) is sounded and the internal
relay is activated. The activation stops when
you push the test button or the gas content
drops below 5-15% of the L.E.L.
The electro-valve resets manually.
Indication LEDs and operation
The green LED shows the presence of the
mains power supply. When first installed, the
green LED blinks for 20 seconds until the
sensor compensates to its surroundings.
When the red LED is lit then the unit is in alarm
mode.
When the yellow LED is lit the unit has an fault.
A blinking red LED means that there was an
alarm condition but it has now passed. The
same applies for a blinking yellow LED and the
fault condition.
When the test button is pressed, the system is
tested and restarted. During the test the internal
circuits are checked, the relay is activated, and
the internal buzzer sounds. Also, during the test
all alarm and fault indications are reset.
After the test and if an electro-valve was
connected to the unit, a manual reset of the
electro-valve must be done.
Electro valve connections
The gas supply is automatically turn OFF in the
event of an alarm or fault condition. The electro-
valve can only be reset manually by the user, by
pressing on point “Α” as show in figure 1.
Depending on the type of electro-valve used,
the corresponding connection diagram is
shown in figure 5. Care must be taken to
position the link of JMP1 in the correct position.
It is suggested that this unit is used in
cooperation with Οlympia Electronics Electro-
valves type BS-684 (12V N.O.) Or BS-682 (
230V AC N.O.). The connection cable, when
you use BS-684, must be at least 2x2.5mm
diameter and no more than 4m length.
Figure 4 shows the connection of multiple
detectors in a network connection, for covering
a larger area and using one 12V DC NO
electro-valve.
Attention!! The position link of JMP1 set the
relay status.
If a link is set on A ( figure 4 ) the relay is
energized (NO) in normal condition and on
alarm or fault condition the relay is not
energized.
The opposite occurs if a link is set on B.
ATTENTION!! The devices must not be tested
using gas filled lighters because the sensor will
be destroyed.
