3Cautions when using gas sensors
1. Exposure to silicone vapours
If silicone vapours adsorb onto the sensor’s surface, the internal sensing element maybe be
coated, irreversibly inhibiting sensitivity. Avoid exposure where silicone adhesives, hair grooming
materials or silicone rubber/putty may be present.
2. Highly corrosive environment
Exposure to corrosive materials such as H2S, SOx, Cl2, HCl, etc. for extended periods may
cause irreversible damage to the sensor.
3. Water
Sensor performance maybe adversely affected due to soaking, splashing or water condensing on
the sensor surface. Exposure to salt water spray will adversely affected sensor performance.
Light condensation under conditions of indoor usage should not pose a problem for sensor
performance.
4. Freezing
If freezing occurs on the sensor’s surface irreversible damage may occur to the internal sensing
element.
5. Usage in high density of gas
Sensor performance maybe adversely affected if exposed to a high density of gas for a long
period of time.
6. Explosive Limits
Different combustible gasses have their own Lower Explosive Limits (LEL). Our gas sensors are
calibrated against 20% LEL LPG in Air.
7. False positive alarms
False positive alarms can be caused by differing concentrations of various aerosols, perfumes,
resins, epoxies, paints, solvents, alcohol, hydrogen, gases and fuels.

4Features
The FD-2 gas detector offers the following features –
§Self testing capability
§Microprocessor control
§Single Sensor
§Audible and visual alarms
5Specification
Voltage: 10V-30V DC
Current: Total 350mA Max
Alarm: 20% LEL (Lower Explosive Limit)
6Introduction
The Contour model LPG, Petrol and CNG detector is the product of continuing research and
development, which BEP Marine Ltd devotes to their product range. The 600 series detectors use the
latest in solid state technology available, with a microprocessor control head connected to the latest in
sensor technology. The FD-2 detector uses a single sensor with both visual and audible alarms.
There is a test switch to check the operation of the sensor with indicators for fault detection.
Read these installation and operation instructions carefully before installing, as any damage caused
by faulty installation will result in the warranty being null and void.
There is no power on/off switch provided. It is intended that for maximum protection the unit should be
on all the time while you are on your boat or in your vehicle.
7Fault Detection
The nominal alarm point of the FD-2 is 20% of the LEL (Lower Explosive Limit) of LPG/CNG in Air. In
the event of a gas leak and the alarm activating, close the manual valve on your gas bottles and open
hatches to ventilate the area. All fans and blowers used to ventilate must be ignition-protected types.
In the event of a sensor being contaminated, damaged, cable shorting or a faulty connection, the
amber light will come on for the sensor. If the sensor fault persists then the sensor could be damaged
and will need to be replaced.
In detecting LPG the sensor can also detect hydrocarbons in other products such as cleaners and
strong adhesives, this can cause nuisance alarms. See section 3 - ‘Cautions when using gas sensors’
for more details.

10 Control Head Installation
For ease of operation, the control head should be mounted in a convenient position close to your gas
appliances and in a position where the control head can be seen and heard easily. The unit can be
either surface mounted or recessed into a 2.5mm panel.
11 Sensor Installation
§The sensor is supplied with a 5-meter cable.
§For LPG and Petrol fumes, which are heavier than air, mount the sensor in a low dry position
where the gas is likely to collect. The sensor must be mounted clear of bilge water.
NOTE: If the sensor gets wet then the sensor becomes inoperable and must be replaced.
§For CNG, which is lighter than air, mount the sensor just below ceiling height but not above
cooking or heating appliances.
§Fasten the sensor with the supplied screws.
§Route the sensor cable through to the control head and connect as per the wiring diagram.
12 Operation
On applying power to the unit, the control head goes through a test cycle. This will take approximately
45 seconds. During this period the sensor heads are being cleaned and tested, at this time there will
be a slow beep from the audible alarm and all the lights will flash amber. Towards the end of this
period the pulse of the beeper and lights will increase, if the unit senses that the environment is clear
then the control head will go into safe mode. The beeper will turn off and the sensor lights will change
to green.
13 Test Button
When operated in normal operation it will -
§Sounds the keyboard beeper
§Turn light red
Pressing the switch again cancels the above.
14 Indicator Display
SENSOR
Green: Sensor on safe, no fumes, no beeping
Amber: Sensor fault, slow beeping
Red: Alarm. Gas present, fast beeping
AUDIBLE ALARM SOUNDS
Warming up: Medium slow, all lights flash amber
Alarm: Fast, sensor lights red
Fault: Slow, sensor lights amber
