This manual containsinformation on the installation and the operation of the SF340modular Carbon Monoxide alarm.THIS ALARM SHOULD ONLY BE INSTALLEDBY A COMPETENT PERSONALL ELECTRICAL WIRING SHOULD BE INSTALLEDIN ACCORDANCE WITH THE CURRENT WIRING REGULATIONS OFTHE INSTITUTE OF ELECTRICAL ENGINEERS1. WHAT IS CARBON MONOXIDE?Carbon Monoxide is a highly poisonous gas which is releasedwhen 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 homeGas, coalor woodfireBoiler orHeaterWaterHeaterPortable gasor paraffinheaterCloggedchimneyor flueCar fumesfromgaragePortablecookingequipmentused inenclosed areasKitchencookerUnder normal operating conditions, in a room where fuelburning appliances are well maintained and correctly ventilated,the amount of Carbon Monoxide released by the appliances isnot dangerous.A dangerous quantity of Carbon Monoxide can occur if one ormore 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 Monoxidesituations:1. Excessive spillage or reverse venting of fuel burning appliancescaused by outdoor ambient conditions such as:i. Wind direction and/or air velocity; including high gusts ofwind. Heavy air in the vent pipes(cold humid air withextended periods between cycles)ii. Negative pressure differential resulting from use of exhaust fans.iii. Simultaneous operation of several fuel burning appliancescompeting for limited internal air.iv. Flue connections breaking loose from clothes dryers, waterheaters or boilers.v. Obstructions in or unconventional flue designs which canamplify the above situations.2. Extended use of unvented fuel burning devices.3. Temperature inversions which can trap exhaust gases near theground.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 Monoxidepoisoning and should be discussed with ALL members of thehousehold: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 thatwhile victims are aware they are not well, they become sodisorientated that they are unable to save themselves by eitherexiting the building or calling for assistance. It is also important tonote 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 whichcontains a fuel-burning appliance.However, if you have more than one appliance but only one alarm,you should take the following into consideration when decidingwhere best to put the alarm:• If there is a fuel burning appliance in a room where peoplesleep, you should put the alarm in that room.• If there is a fuel burning appliance in a room you use a lotsuch 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 thecooking appliance as possible, but near to the room whereyou 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 youwill be able to hear it.4. WHERE SHOULD I PUT THE ALARM?Carbon Monoxide has a similar density to warm air. To ensure themost effective use is made of the alarm it should be fitted at least1.5m (5’) above floor level and at least 1.85m (6’) from the fuelburning appliance. Warm air naturally rises; it is better to install theunit higher rather than lower. The SF340 Series can be fitted on thewall or on the ceiling.ALARM1.85m(6’)(min)1.5m(5’)(min)5. WHERE NOT TO PUT THE ALARMDo 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 affectedby drafts.• Where the airflow to the alarm could be obstructed by curtainsor furniture.• Where dust or dirt could collect and block the sensor.• Where the temperature could drop below -5ºC or rise above 40ºC.• Where it could be easily knocked or damaged.• Within 1.5m (5 feet) of any cooking appliance.6. OPERATING OF THE ALARMThe detector is not fitted with an on/off switch, it is automaticallyswitched on when the power source is activated. This is to ensurethe detector can not be inadvertently switched off and thereforefail to detect a build up of Carbon Monoxide.Normal operationWhen the unit is powered from the primary power source (e.g.230Vac, 12/24Vdc), the green light will be illuminated. (The greenlight will not be illuminated when the battery backup is in use.)When no Carbon Monoxide is present the red alarm light will flashapproximately once every 60 seconds. This indicates the alarm isworking correctly.Alarm conditionsWhen the unit detects Carbon Monoxide, the alarm signal is givencontinuously. The red light will flash and the buzzer will sound.When the unit has been in alarm for a period of 40 minutes, thealarm signal will be given once every 60 seconds.Return to normal operationWhen the Carbon Monoxide disperses, the alarm will automaticallystop. The red light will flash approximately once every 60 seconds(normal operation.)Battery replacement warningWhen the backup battery in the SF340M module needs replacing theaudible alarm will sound a single short beep once every 60 seconds.The battery must then be replaced. The red light will flash once every60 seconds as normal. See Section 10 on batteries.Module replacement warningWhen the module (SF340M) needs replacing, the audible alarm willsound two short beeps every 60 seconds. At this time the modulemust be replaced. The red light will flash once every 60 seconds asnormal.7. SF340 SERIES FEATURESAll units are powered by a primary power source (e.g. 230V or12/24Vdc) and contain a replaceable Module which houses thebattery backup and gas sensing systems.POWER LIGHT (all SF340 models)The green power light will illuminate when the primary powersource is connected and working (230V or 12/24Vdc according tomodel). This light will illuminate even when the Module is not fitted.ALARM/CONFIDENCE LIGHT (all SF340 models)In normal operation the red light will flash once per minute toindicate that the unit is operating correctly. This light will flashwhether the Module is powered from the primary power source orthe battery backup. In the alarm condition it will flash five timesper second.AUDIBLE ALARM (all SF340 models)In the alarm condition the buzzer will sound. Models SF340E,SF340G and SF340H will sound the Morse Code signal for ‘CO’(– • – • – – –). Models SF340F and SF340J will give a continu-ous buzzer sound and this will continue for 90 seconds after thealarm light has stopped. Where models SF340F and SF340J areinterconnected, all units connected will sound the continuousalarm signal. Only units in alarm will have a continuously flashingalarm light.BATTERY BACKUP (all SF340 models)All models in the SF340 series have a battery backup feature. Thispowers the alarm in the event of a primary power failure (230V or12/24Vdc according to model).TEST BUTTON (all SF340 models)All models in the SF340 series have a test button. This ispositioned on the front of the unit and when pushed will causethe audible and visual alarm signals to be given. If the relay andinterconnect options are used, these will also operate when thetest button is pressed. Note that for models SF340F and SF340Jthe buzzer will sound and the relay will operate for 90 seconds.RELAY OUTPUT (Models SF340F & SF340J)The relay provides a single pole changeover (SPCO) volt freecontact which can be used to signal to a control panel or switchan external siren or gas valve. The relay contacts are rated at 3A/ 230Vac and will change state when the unit goes into the alarmcondition or when the test button is pressed. When the unit comesout of the alarm condition the relay will automatically revert to itsoriginal state after a delay of 90 seconds.INTERCONNECT (Models SF340F & SF340J)The interconnect facility enables up to 20 SF340F or SF340Jalarms to be connected together. If one unit goes into the alarmcondition the audible alarm on all interconnected units will sound.This alarm signal is a continuous tone. The unit that caused thealarm can be identified as it will be the only one with acontinuously flashing alarm light. When the unit comes out of thealarm condition the alarm light will stop giving the alarm signal.After a delay of 90 seconds the buzzers of all interconnected unitswill stop sounding and the relays will reset.8.
