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 Detector 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.
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
IN THIS MANUAL PLEASE CONTACT HONEYWELL ANALYTICS.

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
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 home
Gas, coal Boiler or
or wood Heater
fire
Clogged Car fumes
chimney from
or flue garage
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.
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. Warm air naturally rises; it is better to install the
unit higher rather than lower. The SF340 Series can be fitted on the
wall or on the ceiling.

7. SF340 SERIES FEATURES
All units are powered by a primary power source (e.g. 230V o
12/24Vdc) and contain a replaceable Module which houses t
battery backup and gas sensing systems.
POWER LIGHT (all SF340 models)
The green power light will illuminate when the primary power
source is connected and working (230V or 12/24Vdc accordi
model). This light will illuminate even when the Module is not

BATTERY BACKUP (all SF340 models)
All models in the SF340 series have a battery backup feature
powers the alarm in the event of a primary power failure (230
12/24Vdc according to model).
TEST BUTTON (all SF340 models)
All models in the SF340 series have a test button. This is
positioned on the front of the unit and when pushed will caus
the audible and visual alarm signals to be given. If the relay a
interconnect options are used, these will also operate when t
test button is pressed. Note that for models SF340F and SF3
the buzzer will sound and the relay will operate for 90 second
RELAY OUTPUT (Models SF340F & SF340J)
The relay provides a single pole changeover (SPCO) volt free
contact which can be used to signal to a control panel or sw
an external siren or gas valve. The relay contacts are rated a
/ 230Vac and will change state when the unit goes into the a
condition or when the test button is pressed. When the unit c
out of the alarm condition the relay will automatically revert t
original state after a delay of 90 seconds.
INTERCONNECT (Models SF340F & SF340J)
The interconnect facility enables up to 20 SF340F or SF340J
alarms to be connected together. If one unit goes into the ala
condition the audible alarm on all interconnected units will so
This alarm signal is a continuous tone. The unit that caused t

After a delay of 90 seconds the buzzers of all interconnected
will stop sounding and the relays will reset.
