Develop and Practise a Plan of Escape:

    Make a floor plan indicating all doors and windows and at least two escape 

routes from each room. Second storey house 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 fire.

    Determine a place outside your home where all of you can meet, if a fire 

occurs.

     Familiarise everyone with the sound of the smoke alarm and practice 

leaving your home when they hear it.

     Practice a fire drill at least every six months, including drills at night. 

Practice allows you to test your plan before an emergency. You may not be 

able to reach your children. It is important that they know what to do!

What to do when the Alarm Sounds:

  Leave immediately by your plan of escape. 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 if you see smoke seeping through cracks, don’t open that door! Instead, 

use your alternative exit. If inside 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 air is smoky. Breathe shallowly through a wet cloth 

if possible.

  Once outside, go to your selected meeting place and make sure everyone 

is there.

  Call the Fire Brigade from your neighbour’s home - not from yours!

   Don’t return to your home until officials say that it is safe to do so. For 

additional information on fire safety, contact your local Fire Brigade.

Avoid These Locations:

Do not place alarm in the following locations:

   The garage. Gas released when you start your automobile may cause 

false alarms.

   In front of forced air supply ducts used for heating and air-conditioning and 

other high airflow areas.

   In the peak of an “A” frame type of ceiling.

   In areas where temperatures may fall below +0ºC or rise above +40ºC.

    In dusty areas, dust particles may cause smoke alarm to false alarm or fail 

to alarm.

   We do not recommend installation in or directly adjacent to areas of 

high condensation such as bathrooms & laundries due to potential for 

false alarms.

    Kitchen/cooking  areas.

Battery:

  This smoke alarm uses a 3V non replaceable lithium battery to 

automatically provide back-up power to the alarm if the AC power fails. The 

battery will operate the alarm for approximately one to three months with 

AC power off.

  The 3V non replaceable battery has an estimated 10 year life under normal 

working condition.

The Limitations of Smoke Alarms:

   Smoke alarms cannot provide an alarm if smoke does not reach the alarm. 

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 bedrooms, or on a different floor, it may 

not wake up sound sleepers. A smoke alarm in the bedroom, is therefore 

recommended as additional protection.

   Smoke alarms have been significant in saving lives in many parts of the 

world. However, U.S. Government research indicates that they may not give 

early enough warning in up to 35% of fires. Hence, the use of this product 

does not act as a substitute for basic prevention.

  Although smoke alarms can help save lives by providing early warnings of 

a fire, they are not a substitute for an insurance policy.

  This smoke alarm alone will not alert the hearing impaired. Use special 

purpose smoke alarm with lights or vibrating devices, for those hard 

of hearing.

False Alarms:

   Dust generated on building construction sites can cause false alarms. 

The red plastic bag is intended to protect the smoke alarm during the 

building construction phase.

  This smoke alarm is designed to minimise false alarms. Smoking will not 

normally set off the alarm unless smoke is blown directly into the alarm.

  Combustion particles from cooking may set off the alarm if the alarm is 

located close to the cooking surface.

  Because large quantities of combustion particles are generated from spills 

or grilling an alarm with a Hush Control device is preferable near a kitchen 

environment.

  If the alarm does sound, check for a fire before silencing the alarm. If a fire 

is discovered, escape quickly and call the Fire Brigade.
