Should one of the above-mentioned substances set off the alarm, venti-
late the area involved, and restore the sensor to normal conditions by
airing the grill on the front. Such substances might effect the short and
long term performance of the detector.
LIMITATIONS TO THE USE OF THE DETECTOR
- The detector cannot operate without supply which can fail, for exam-
ple, in a power cut, fire, if a fuse blows or if an automatic switch trips,
or in the case of a wrong connection.
- The detector's alarm will not be activated if the gas cannot reach the
sensor. Any kind of hindrance of obstruction of the path of the gas to
the sensor may prevent the alarm from being triggered or delay its acti-
vation
- A gas detector cannot detect gas inside walls, floor or in the ceiling
unless a significant amount of gas reaches the detector.
- A detector located on the ground floor cannot detect methane gas leaks
on the floors above it
- A gas detector installed on the first floor cannot detect gas leaks from
the ground or second floor unless a sufficient amount of gas reaches
the detector.
- A closed door stops gas from reaching a detector on the other side of
the door.
For these reasons the detector should be placed near the gas appliance.
Other suggestions:
- Make sure that all members of the household can hear the sound
alarms.
- It is essential that the detector chosen corresponds to the type of gas
used in the house (methane or LPG) and it is installed in a suitable
place. Otherwise it is possible that the presence of gas will not be reco-
gnised until after the lowest explosive limit has been reached. If both
methane and LPG gas are used in your house, one detector for each
