Placing of the sensor for city and
natural gas (methane CH4):
Mount the external sensor at a height of 15-30 cm
below the ceiling but no further than 4 m from the
gas appliance. Note that the sensor must be moun
-
ted above the highest door or window opening in the
room.
City and natural gas (methane) are lighter than air
and will therefore always rise.
Placing of the sensor for liquefied
gas (propane C3H8 / butane C4H10):
Mount the external sensor at a height of max. 15 cm
above the floor but no further than 4 m from the gas
appliance. Escaping liquefied gas is heavier than
air and sinks to the floor. It spreads across the floor
rather like water - but as a gas - and always seeks
the lowest point.
The sensor may not be mounted in the following positions:
•
places where the sensor is shielded from escaping gas (e.g. behind curtains or in
cupboards)
•
directly above hearths or points of combustion or over a wash basin or sink
•
next to a door, windows, ventilator, fan, air conditioning unit etc
•
in areas where dust or dirt can prevent the sensor from working
•
in areas at risk of explosion
It is essential to observe the prescribed sensor mounting height! For your
own safety and reassurance, please obtain information from your supplier
regarding their gas type and its properties!
INSTALLATION INSTRUCTIONS
The sensor may be installed
only in dry, interior rooms and must be correctly placed accor-
ding to the type of gas to ensure faultless operation of the alarm system.
For the connection of the sensor to the alarm unit, please consult the instructions for use of
the sensor!
The standard length of the sensor lines is 2.50 m. If you want to increase the length of the
sensor lines, you have to use a 3-pole cable. Based on the line length, the following minimum
cross sections apply:
cable cross section 3 x 0.75 mm²: maximum length 10 m
cable cross section 3 x 1.5 mm²: maximum length 20 m
Important! The sensor cable must be installed as a fixed,
surface-mounted line.
