Important Information

This alarm is designed for installation by a qualified electrician, in accordance with the latest I.E.E. Regulations and in regard to relevant Building Regulations/BS Codes of Practice.

Hard wired smoke or heat alarms require a constant 230V AC supply. Battery Back-up models additionally require a healthy battery too.
A healthy mains supply is indicated by a constant green L.E.D. (mains) indicator.
Test the alarm weekly by pressing (and holding) the test button. The alarm and all those interconnected to it will sound.
Vacuum your alarms regularly to reduce the likelihood of nuisance alarms, caused by dust contamination.
Never paint or expose alarm to water – this is a 230V alarm.(If painting or building work is being carried out close to alarm, temporarily cover with a plastic bag, or the dust cover supplied.)
Smoke alarm operating temp & humidity range: 0° C to 40° C, 93% RH, non-condensing.
Storage and Transport Conditions: -20° C to +60° C, 5-95%Rh (non-condensing)
If the alarm chirps every 30-40 seconds at the same time as the red LED, it indicates the battery needs replacing. (If you are in rented property, advise your Landlord.)
If the alarm chirps every 30-40 seconds in between red LED flashes this indicates the alarm is in error. Press and hold the Test button to reset the unit but replace it if the alarm does re-enter error mode.
If there is any question to the cause of an alarm, it should be assumed that the alarm was due to an actual fire and the dwelling should be evacuated immediately.

Smoke and heat alarms will only function if properly selected, located, installed and maintained as per Kidde instruction user guides.

Types of Alarm

DC alarms 9V battery powered units, but will only function if battery is in good condition –check regularly. (BS5839 Pt6: Grade F).
AC/DC alarms 230V mains – for professional installation. Minimum required to comply with relevant local Building Regulations. Interconnectable to other Kidde AC Alarms, so all will sound when one is triggered. If mains power is lost, will operate via battery power if batteries are fresh/properly installed.
Some models use replaceable 9V (PP3 type) batteries, others sealed-in rechargeable batteries. (BS5839 Pt6: Grade D). This type is the minimum
grade acceptable on new or materially altered dwellings.

WARNING
This alarm cannot be operated from power derived from a square wave or modified sine wave inverter. These types of inverters are sometimes used to supply power to the structure in off grid installations, such as solar or wind derived power sources. These power sources produce high peak voltages that will damage the alarm.

Alarm Types

Ionisation (Ion) alarms are the most common type and provide early detection against fast flaming fires and other fires. Most suitable for dining and living room areas. Ion alarms contain 0.9 microcurie of Americium 241, a radioactive material. BS5839 Pt6 recommend however, that optical alarms are also used especially in locations where steam or cooking fumes, from a nearby room could cause nuisance alarms.
No one type of alarm is considered suitable for all locations.

Optical (Photo-Electric) alarms are increasingly used and are less prone to nuisance alarms from cooking fumes. They are therefore the recommended type in BS5839 Pt6, for fitting near kitchen areas and on escape routes/circulation spaces.

KIDDE-1SFW-Smoke-and-Heat-Alarm-02

Heat alarms are for use in areas where Ion or Optical smoke alarms would be unsuitable e.g. kitchens, boiler rooms, garages. However, they must always be used interconnected to smoke alarms – do not use in isolation. (They will typically go into alarm when the temperature reaches approximately 57°C.) Suitable for new Building Regulations applicable 1/7/2000 regarding use in kitchens.

How to Operate/Test the Alarm

Operation and L.E.D. Status

When your alarm is correctly installed to the mains supply, the green L.E.D. light will be on. The red L.E.D. will blink every 30-40 seconds to indicate the sensor is operating correctly. If the alarm senses products of combustion, its 85dB horn will be activated.
The red L.E.D. will flash rapidly on the alarm sensing smoke/heat. (Other interconnected alarms will also sound to warn those in other parts of the property.) This will continue until the sensor chamber is clear.
If the red L.E.D. blinks every 30-40 seconds and the alarm chirps in between, it indicates failure of the sensing chamber. Press and hold the test button to perform a test but if the unit re-enters error mode replace the alarm.
In the case of a heat alarm, it is a class A2 device and will alarm between 54°C and 70°C. and will return to its standby mode when the temperature drops to normal levels. Regularly check and ensure that the green L.E.D. is lit – if not, check the consumer unit/circuit breaker connection. As with previous point above, if in doubt, consult an electrician or your Landlord.

Testing

Utilise the test button to test the alarm. Do not use naked flames as this does not replicate smoke and may cause physical damage to the alarm or ignite combustible materials and start a structure fire.
Test all your alarms weekly – remember they are life saving devices, protecting the family and home.
Press and hold the test button until the alarm sounds. All interconnected alarms will also sound. (Do not stand too close to the alarm during testing – hearing may be damaged.) Immediately after completing the test cycle, the 2SFW AND 2SFWR models will enter into Hush mode and the red LED will flash approximately every 10 seconds.

Hush Button

This feature temporarily desensitises the alarm circuit for approximately 7 minutes. This feature is to be used only when a known alarm condition, such as fumes from cooking, activates the alarm. The alarm is desensitised by pushing and releasing the “HUSH” button on the alarm cover. If the smoke is not too dense, the alarm will silence immediately and the red LED will flash every 10-11 seconds for approximately 7 minutes. This indicates that the alarm is in a temporarily desensitised condition. The alarm will automatically reset after approximately 7 minutes and sound the alarm if particles of combustion are still present and releasing. The “HUSH” feature can be used repeatedly until the air has been cleared of the condition causing the alarm. The triggering alarm is signified by a rapidly flashing red LED. For safety reasons, the triggering alarm signal can only be silenced by activating the Hush button on that unit.
Note: Dense smoke will override the hush control feature and sound a continuous alarm. Caution: Before using the alarm hush feature, identify the source of the smoke and be certain a safe condition exists. (On heat alarms with hush, the alarms sensor has detected a high temperature – e.g. 57°C. Check for possible causes carefully.)

Nuisance Alarms

Warning: Persistent nuisance alarms indicates incorrect type and/or siting of alarm. Review with your installer or Landlord after cleaning as described in Section 7 (Maintenance).

Battery Checking/Changing*

Loose Battery Models

Low Battery Indicator (AC models with loose battery only)
If you hear the alarm chirp continuously every 30-40 seconds at the same time as the led flashes (and have not just pressed the hush button) it indicates the battery voltage is at an unacceptably low level. Replace the battery at the next possible opportunity. WARNING! Removal of battery(s) and disconnection or loss of AC power will render this alarm inoperative

Battery Change

Firstly isolate the mains supply at the consumer unit by identifying the appropriate circuit. This may be a dedicated fuse marked “Fire/Smoke Alarms” or with a symbol such as .
(If you rent your property, your Landlord may arrange this service for you .)
The green L.E.D. should now be out. If not, recheck before proceeding.
Slide screwdriver blade in recess to unlock from base, as indicated by arrow to release locking tab
With screwdriver still inserted push alarm hard with palm of hand in direction of arrow, to slide off it’s base.
Note correct position of battery and install replacement type as listed below. The alarm cannot be replaced without a battery installed.
Reverse procedure to re-install alarm. We recommend the use of alkaline for a longer service life.
NOTE: TEST ALARM USING TEST BUTTON AFTER BATTERIES ARE REPLACED.
When you have fitted a fresh battery, check test button; if horn sounds then reverse the process above, reconnect to the mains and switch circuit back on at Consumer Unit

Good Safety Habits

Install and maintain Fire extinguishers on every level of the home and in the kitchen, basement and garage. Know how to use a fire extinguisher prior to an emergency.
Current studies have shown smoke alarms may not awaken all sleeping individuals, and that it is the responsibility of individuals in the household that are capable of assisting others to provide assistance to those who may not be awakened by the alarm sound, or to those who may be incapable of safely evacuating the area unassisted.
Make a floor plan indicating all doors and windows and at least two escape routes from each room. Second storey windows may need a rope or chain ladder.
Have a family meeting and discuss your escape plan, showing everyone what to do in case of a fire.
Determine a place outside your home where you can meet if a fire occurs.
Practice a fire drill at least every six months, including fire drills at night. Ensure that small children hear the alarm and wake when it sounds. They must wake up in order to execute the escape plan. Practice allows all occupants to test your plan before an emergency.
You may not be able to reach your children. It is important they know what to do.

What to do when the Alarm Sounds

Alert small children in the home.
Leave immediately by your escape plan. Every second counts, so don’t waste time getting dressed or picking up valuables.
In leaving, don’t open any inside door without first feeling its surface. If hot, or you see smoke seeping through cracks, don’t open that door!Instead use your alternative exit.
If the inside of the door is cool, place your shoulder against it, open it slightly and be ready to slam it shut if heat and smoke rush in.
Stay close to the floor if the air is smoky.Breathe shallowly through a cloth, wet if possible.
Once outside, go to your selected meeting place and make sure everyone is there.
Call the fire brigade on 999 from your neighbour’s home or a call box – not from yours.
Don’t return to your home until the fire officials say that it is all right to do so.
There are situations where a smoke alarm may not be effective to protect against fire. For instance:
- smoking in bed
- leaving children unsupervised.
- cleaning with flammable liquids, such as gasoline
- fires where the victim is intimate with a flaming initiated fire; for example, when a person’s clothes catch fire while cooking.
- incendiary fires where the fire grows so rapidly that an occupant’s egress is blocked even with properly located detectors.

Checking Battery Back-up on Rechargeable Long Life Models

There is no user replaceable battery on rechargeable models. This will be indicated on the product; additionally there is no battery compartment. To check charge on these models, switch off the alarms AC supply at the Consumer Unit/Fuse Box. The green
L. E.D. will go out. Push the test button to check battery only mode works. If the rechargeable battery is depleted, the low battery beep will be heard once every 40 seconds. If the alarm has received AC mains power for a minimum of 3 days prior to this, you will need to have the unit changed by your installer or Landlord.
WARNING! Loss of AC power and depleted battery(s) will render this alarm inoperative

Maintenance

Your alarm is a life saving device. Spending a few minutes each month in vacuuming off any excess dust will enhance its performance and reduce the likelihood of nuisance alarms.
Vacuum up to the grill and through the slots where dust/talc etc. can enter. Wipe off with a very mildly damp cloth. Never use cleaning agents/polishes etc..

Never attempt to open the inside of the alarm this will invalidate its guarantee.

What to do in an Emergency

If an alarm sounds without anyone pressing the test button you have a potential emergency.
Donʼt panic – you will need to think clearly to ensure all family members escape as soon as possible.
Never stop to collect belongings etc. – they are replaceable.
Check the temperature of door handles or doors to check if hot –
if hot do not open them – a fire will be raging the other side of the door.
Find an alternative escape route.
Keep doors/windows closed to contain the fire after you have passed through them.
Call 999 from a neighbourʼs phone or call box.
This is preferable to using a mobile.
Do not re-enter the property until advised it is safe to do so by a Fire Brigade Officer.

Troubleshooting

Always turn off the mains supply to AC alarms before checking connections etc..

Symptom	Possible cause/solutions
1. Green L.E.D. not lit	a. _Loss of mains power – check at Consumer Unit

for Blown Fuse or tripped Circuit Breaker._

b. Check cables at back of alarm, are correctly seated

/ wired in and the alarm is pushed fully home (see “Battery Changing” section).

2. Frequent nuisance alarms| See sections 2,3,4 and 7. If sited incorrectly/not regularly cleaned as section 11, nuisance alarms can occur.
3. Alarm chirps every 30-40 seconds| Verify green LED is lit continuously then see section 5 to replace battery if applicable. If unit has rechargeable battery or problem persists after installing a new battery, contact customer service.
4. Alarm does not sound when test button pressed and held.| See parts 1a and 1b above. Have installer re check wiring if Green LED is illuminated, but alarm does not appear to function. If no Green LED check consumer unit. Alarm with still function on battery power, if battery is in serviceable state. <Red LED will blink about once a minute to confirm>. Check via Test Button.
5. Interconnected alarms do not sound when test button is pressed and held.| See part 1b above – consult a qualified electrician or your Landlord to remedy as soon as possible.

10. Useful Hints

Smoke/heat alarms can only operate correctly if smoke particles/heat reach the unit. Correct selection/siting and installation are covered in the installers manual, who fitted your alarm/s.
Building Regulations require new homes to have 1 hard wired smoke alarm per floor and to be interlinked. From 2000 they will additionally require an interlinked heat alarm to be fitted in most kitchens too. i.e. 3 alarms per property.
With the exception of garages/kitchens/bathrooms it is recommended that smoke alarms are fitted in every room and outside all sleeping areas too.
A professional electrician should be employed for all mains powered (hard wired) alarms.
If you are redecorating your home, paint fumes can contaminate the alarm –
temporarily cover the unit with a plastic bag (during this time the alarm will not function). Never paint the alarm.
Only remove the bag when the paint is thoroughly dry.
If you extend your property, review your alarm requirements.
Smoke/heat alarms should be replaced every 10 years or sooner.
These products are designed for domestically scaled premises.
At the end-of-life for recycling purposes, contact Kidde for instructions on removing the rechargeable batteries from models so equipped as these batteries are not designed for user removal.

Limitations of Smoke/Heat Alarms

Warning!

Smoke alarms are devices that can provide early warning of possible fires at a reasonable cost; however, alarms have sensing limitations. Leading authorities recommend that both ionisation and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fires that can occur within the home. Ionisation sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than ionisation alarms.
Heat alarms are useful in areas with condensation/dust/high humidity, such as kitchens and lofts. Heat alarms MUST ALWAYS be interconnected to smoke alarms.
The heat alarm it is a class A2 device and will alarm between 54°C and 70°C. – they are not suitable for use as a fire safety device independently, they must always be used in conjunction and interconnected to smoke alarms.
Loose batteries, where fitted must be of the specified type, in good condition and installed properly.
AC only powered alarms will not operate if AC power has been cut off such as by an electrical fire, an open fuse or loss of mains supply.
All alarms must be tested regularly to make sure the batteries and the alarm circuits are in good operating condition.
Life safety from fire in residential occupancies is based primarily on early notification to occupants of the need to escape, followed by the appropriate egress actions by those occupants.
Fire warning systems for dwelling units are capable of protecting about half of the occupants in potentially fatal fires. Victims can be involved with the fire, too old or young, or physically or mentally impaired such that they cannot escape even when warned early enough that escape should be possible. For these people, other strategies such as protection-in-place or assisted escape or rescue are necessary.
Smoke alarms cannot provide an alarm if smoke does not reach the unit. Therefore, smoke alarms may not sense fires starting in chimneys, walls, on roofs, on the other side of a closed door or on a different floor. If the alarm is located outside the bedroom or on a different floor, it may not wake up a sound sleeper. Equally heat alarms will only be triggered if they are correctly sited to detect heat. The use of alcohol or drugs may also impair ones ability to hear the alarm. For maximum protection a smoke alarm should be installed in each sleeping area on every level of a home. Hearing impaired occupiers should consider fitting additional strobe accessories to give a visual alarm.
Although smoke/heat alarms can help save lives by providing an early warning of a fire, they are not a substitute for an insurance policy. Home owners and renters should have adequate insurance to protect their property.
