detector functions, as required by Underwriters' Labora- 
tories. This is the only correct way to test the unit. 
NOTE: If the alarm horn produces a loud continuous sound and 
the red LED flashes when you are not testing the unit, this means 
the detector has sensed smoke or combustion particles in the air. 
Verify that the alarm is a result of a possible serious situation, 
which requires your immediate attention.  
• The alarm could be caused by a false situation. Cooking 
smoke or a dusty furnace, sometimes called "friendly fires" can 
cause the alarm to sound. If this happens, open a window or 
fan the air away to remove the smoke or dust. The alarm will 
turn off as soon as the air is completely clear. 
  CAUTION: Do not disconnect the battery from the detector. 
This will remove your protection from fires. 
•  If there is any question as to the cause of an alarm, it 
should be assumed that the alarm is due to an actual fire 
and the residence should be evacuated immediately. 
•  If the alarm horn begins to beep once every 30 sec, this signal 
means that the detector's battery is weak. Install a new battery 
immediately. Keep fresh batteries on hand for this purpose. 
6.2 Tips to Enhance Your Protection 
From Fires 
Putting up smoke detectors is only one step in protecting your family 
from fires. You must also reduce the chances of fires starting in your 
home. You must also increase your chances of escaping safely if one 
does start. To have a good fire safety program you must apply the 
following tips to enhance your family's protection from fires: 
A. Install smoke detectors properly. Carefully follow all the 
instructions in this manual. Keep your smoke detectors 
clean and test them every week. 
B. Remember that detectors that do not work will not alert 
you. Replace your smoke detectors immediately if they are 
not working properly.7 
C. Follow fire safety rules, and prevent hazardous situations:  
• Use smoking materials properly. Never smoke in bed. 
• Keep matches and cigarette lighters away from children. 
• Store flammable materials in proper containers. Never use them 
near open flame or sparks. 
• Keep electrical appliances in good condition. Do not overload 
electrical circuits. 
• Keep stoves, fireplaces, chimneys, and barbecue grills grease 
free. Make sure they are properly installed and away from any 
combustible materials. 
• Keep portable heaters and open flames such as candles away 
from combustible materials. 
• Do not allow rubbish to accumulate. 
• Keep a supply of extra batteries on hand for your battery 
powered smoke detectors. 
D.  Develop a family escape plan and practice it with your entire 
family. Be sure to include small children in your practice. 
• Draw a floor plan of your home, and find two ways to exit from 
each room. There should be one way to get out of each 
bedroom without opening the door. 
• Explain to children what the smoke detector alarm signal means. 
Teach them that they must be prepared to leave the home by 
themselves if necessary. Show them how to check to see if doors 
are hot before opening them. Show them how to stay close to the 
floor and crawl if necessary. Show them how to use the alternate 
exit if the door is hot and should not be opened. 
• Decide on a meeting place which has a safe distance from your 
house. Make sure that all your children understand that they 
should go and wait for you there if there is a fire. 
• Hold fire drills at least every 6 months, making sure that everyone, 
even small children, knows what to do to escape safely. 
• Know where to go to call the Fire Department outside your home.  
• Provide emergency equipment, such as fire extinguishers, and 
teach your family to use this equipment properly. 
6.3 More Tips on How to Face a Fire at
