6 Introduction
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.
7 Fault 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.
