TESTING YOUR ALARM
A green power light indicates power is supplied. The alarm should be tested weekly by pushing
and holding the test button on the front of the unit. The alarm signal should sound. If relay
models are in use or units are interconnected please be aware that the relay function will be
activated upon test.
CARE AND MAINTENANCE OF ALARM
The outside casing of the alarm should be wiped occasionally with a cloth. Ensure that the
holes on the front are not blocked with dirt and dust. DO NOT USE CLEANING AGENTS,
BLEACH OR POLISH.
IMPORTANT
·
Ideally it is recommended that a carbon monoxide alarm should be
installed in or near to every room which contains a fuel burning appliance
such as gas fires, central heating boilers, room heaters, water heaters,
cookers, grills etc
·
Ensure that the alarm buzzer can be heard by all those who are
intended to hear it.
·
Seek medical help if it is suspected that a member of the household is
suffering from carbon monoxide poisoning.
IF FURTHER DETAILS ARE REQUIRED THAT DO NOT APPEAR

INTRODUCTION
Thank you for purchasing this alarm which is designed to detect the presence of carbon
monoxide (CO) gas. This manual contains information on the installation and the operation
of the SF340 modular carbon monoxide alarm.
THIS ALARM SHOULD ONLY BE
INSTALLED BY A COMPETENT PERSON
ALL ELECTRICAL WIRING SHOULD BE
INSTALLED IN ACCORDANCE WITH THE
CURRENT WIRING REGULATIONS OF THE
INSTITUTE OF ELECTRICAL ENGINEERS
2. WHAT ARE THE SYMPTOMS OF CARBON MONOXIDE POISONING?
The following symptoms are related to carbon monoxide poisoning and should be discussed
with ALL members of the household:
Mild exposure:
Slight headache, nausea, vomiting, fatigue (often
described as “flu-like” symptoms)
Medium exposure:
Severe throbbing headache, drowsiness,
confusion, fast heart rate.
Extreme exposure:
Unconsciousness, convulsions, cardiorespiratory
failure, death.
Many reported cases of carbon monoxide poisoning indicate that while victims are aware
they are not well, they become so disorientated that they are unable to save themselves by
either exiting the building or calling for assistance. It is also important to note that young
children and pets may be the first to be affected.
3. IN WHICH ROOM SHOULD I PUT THE ALARM?
Ideally you should have an alarm in or near every room which contains a fuel-burning appliance.
However, if you have more than one appliance but only one alarm, you should take the
following into consideration when deciding where best to put the alarm:
·
If there is a fuel burning appliance in a room where people sleep, you
should put the alarm in that room.
·
If there is a fuel burning appliance in a room you use a lot such as a
sitting room, you should put the alarm in that room.
·
If you live in a bed-sit put the alarm as far away from the cooking
appliance as possible, but near to the room where you sleep.
·
If the fuel burning appliance is in a room not normally used (e.g. a boiler
room) put the alarm just outside the room so you will be able to hear it.
4. WHERE SHOULD I PUT THE ALARM?
Carbon monoxide has a similar density to warm air. To ensure the most effective use is made
of the alarm it should be fitted at least 1.5m(5’) above floor level and at least 1.85m (6’) from
the fuel burning appliance.

5. WHERE NOT TO PUT THE ALARM
Do not place the alarm in the following areas:
·
Outside the building.
·
In or below a cupboard.
·
In a damp or humid area.
·
Directly above a sink or cooker.
·
Next to a door or window or anywhere it could be affected by drafts.
·
Where the airflow to the alarm could be obstructed by curtains or furniture.
·
Where dust or dirt could collect and block the sensor.
·
Where the temperature could drop below -5ºC or rise above 40º C.
·
Where it could be easily knocked or damaged.
·
Within 1.5m (5 feet) of any cooking appliance.
1. WHAT IS CARBON MONOXIDE?
Carbon monoxide is a highly poisonous gas which is released when fuels are burnt. It is
invisible, has no smell and no taste, therefore it is very difficult to detect with the human
senses.

Potential danger areas in your hom e
Under normal operating conditions, in a room where fuel burning appliances are well maintained
and correctly ventilated, the amount of carbon monoxide released by the appliances is not
dangerous.
A dangerous quantity of carbon monoxide can occur if one or more of the following
conditions exists:
1.
An appliance is faulty or badly maintained.
2.
A flue is partially or totally blocked.
3.
A room is not adequately ventilated.
The following conditions can result in transient carbon monoxide situations:
1.
Excessive spillage or reverse venting of fuel burning appliances caused by
outdoor ambient conditions such as:
i.
Wind direction and/or air velocity; including high gusts of wind. Heavy
air in the vent pipes(cold humid air with extended periods between cycles)
ii.
Negative pressure differential resulting from use of exhaust fans.
iii.
Simultaneous operation of several fuel burning appliances competing
for limited internal air.
iv.
Flue connections breaking loose from clothes dryers, water heaters or
boilers.
v.
Obstructions in or unconventional flue designs which can amplify the
above situations.
2.
Extended use of unvented fuel burning devices.
3.
Temperature inversions which can trap exhaust gases near the ground.
4.
A car running in an open or attached garage near a home.

WARNING
Actuation of your carbon monoxide(CO) alarm indicates the presence of
carbon monoxide(CO) which can KILL YOU.
THIS CARBON MONOXIDE ALARM MAY NOT PROTECT PEOPLE WHO
ARE AT SPECIAL RISK BY REASON OF AGE, PREGNANCY OR MEDICAL
CONDITION. THESE INDIVIDUALS MAY CONSIDER USING WARNING
DEVICES WHICH PROVIDE AUDIBLE AND VISUAL SIGNALS FOR CARBON
MONOXIDE CONCENTRATION UNDER 30PPM. IF IN DOUBT PLEASE
CONTACT YOUR MEDICAL PRACTITIONER.
A CARBON MONOXIDE ALARM IS NOT A SUBSTITUTE FOR A SMOKE
ALARM OR A COMBUSTIBLE GAS DETECTOR.
This carbon monoxide alarm is designed to detect carbon monoxide gas
from
any
source of combustion including wood, coal, coke, oil, petrol and gas.
THIS CARBON MONOXIDE ALARM IS NOT:
·
Designed to detect smoke fire or any other gas.
·
To be seen as a substitute for the proper servicing of fuel-burning appliances
or the sweeping of chimneys.
·
To be used on an intermittent basis, or as a portable alarm for the spillage of
combustion products from fuel burning appliances or chimneys.
CAUTION
This carbon monoxide alarm is designed for indoor use only. Do not expose to
rain or moisture. Do not knock or drop the alarm. Do not tamper with the
alarm as this could cause electric shock or alarm malfunction. The alarm will
not protect against the risk of carbon monoxide poisoning when the battery
back up is no longer functioning. This alarm will only indicate the presence of
carbon monoxide gas at the sensor. Carbon monoxide gas may be present in
other areas. Do not paint.
