Clas Ohlson 18-2447 Quick Start Manual

LP Gas alarm
Art.no 18-2447, 32-8624
The gas alarm requires 2–3 minutes to warm up whenever it is powered up. During this period
the gas alarm may not respond (no alarm) to gas or a push-button test.
Placement
For maximum protection the alarm should be installed on a flat wall in the room where the gas
appliance is situated and a gas leak is most likely to occur. In most installations this will be close
to the cooker in the kitchen or caravan etc. This gas alarm is design to detect primarily LP-gas
(liquefied petroleum gas); however it also detects the presence of natural gas and should be
mounted differently depending on the type of explosive gas you intend to detect.
Natural gas is lighter than air so the alarm should be installed higher than the top of the highest
outside window or door within a room. This will usually be no more than 30 centimetres from
the ceiling. It should also be between 1 metre and 5 metres from the gas appliance. LPG is heavier
than air so the alarm should be installed close to the lowest point, not more than 30 centimetres
from the floor and not more than 4 metres from the appliance.

Installation
This gas alarm is design for easy installation and comes complete with screws, mounting bracket
and adaptor. Attach the mounting bracket to wall with the screws provided then twist and lock
the alarm into place (clockwise). Now choose to either plug alarm into a standard 230 V AC outlet
using provided adaptor or directly to a 12 V DC source. When the alarm is properly installed,
green LED indicates the alarm is receiving sufficient power. Wait for 2–3 minutes, then push and hold
the test button for 5–10 seconds. If the alarm is activated the unit is now ready to detect and protect.
Input rating: 100–240 V AC ~ 50–60Hz

Testing and maintenance
Test alarm by using the test button at least once a week and always after long absences. Check
that the green light diode is active, indicating sufficient current supply. Then press and hold the test
button until the alarm sounds. Also check that the red light diode flashes during alarm test.
A simple confidence check can be conducted by using a small disposable cigarette lighter and
pressing the lever normally used to maintain the flame without
lighting it. If this is then held close to the alarm, the red LED
light will come on and the alarm will sound. Make sure to air
out the room after testing. Vacuum unit regularly and use
a cloth to wipe the outside of the alarm. When used in for
example boats, caravans, mobile homes etc. we recommend
that you store the gas alarm in normal room temperature
during the winter season, this prolongs its life expectancy.
A gas alarm should be replaced after around 5 years, because
the gas sensor thereafter gradually changes sensitivity.
Gas safety
If alarm sounds, open all windows and doors to allow the gas to disperse. Don't switch on/off
lighting, exhausting fan or any kind of electrical appliance to avoid explosion. Check all the gas
appliances, extinguish any open flames including cigarettes and turn off the gas supply and check
hose connectors and pipes for leakages. It's crucial that the source(s) of the leak is determined
and appropriate repairs are made. Contact the supplier of the gas equipment or the fire brigade if
the problem is not located. In case of immediate danger, always call the fire brigade from outside
the building.
• When leaving the room where the gas is used, always turn off any equipment and the gas supply.
• Do not make any changes in the gas installation without proper knowledge.
• Let a specialist inspect your gas installations regularly.
• Avoid sleeping in direct proximity to the gas installations.
