Please read the entire instruction manual before use and save it for future 
reference. We reserve the right for any errors in text or images and for making any 
necessary technical changes to this document. If you should have any questions 
concerning technical problems please contact our Customer Services. 

Placement of the smoke alarm

1.  The smoke alarm should be placed in the ceiling near bedrooms.
2.  If the bedrooms are in dierent parts of the dwelling, a smoke alarm should  

be placed in each room.

3.  In a building with several oors there should be at least  

one smoke alarm on every floor.

4.  Make sure the sound from the smoke alarm is distinctly heard.
5.  The earlier your family is warned the greater the chance of saving family 

members and salvaging property.

Interconnection

Pull cable (e.g. oval wire SKF 2 x 0.75 mm) between the smoke alarms  
that are to be connected. The smoke alarms should be connected in parallel.  
Follow the colour coding. Connect e.g. black to black and white to white.

Do not put a smoke alarm in the following places

1.  Do not place a smoke alarm in a kitchen with poor ventilation. Smoke and 

fumes from the preparation of food and baking can trigger the alarm.

2.  Do not place smoke alarm near fans or ventilation conduits. Smoke could 

drift in their direction instead of toward the smoke alarm.

3.  Do not place a smoke alarm in a garage. A car’s exhaust may trigger an alarm.

it slightly.

(see further instructions).

a few seconds to test the alarm sound.

5.  Next check that the red light diode is blinking a 

few times per minute.

6.  Attach the bottom plate to the ceiling with the 

enclosed screws. Then screw the smoke alarm 
tightly to the bottom plate.

Alarm Pause

Silence your smoke alarm for approx. 10 min by momentarily pressing the test 
button. Ideal when non-emergency smoke (e.g. steam) causes nuisance alarms. 
Two signals are heard when the smoke alarm  
automatically resets after 10 minutes.

Test and care

1.  Test the smoke alarm at least once every month, and preferably once per 

week, e.g., when you house clean.

2.  Always test the smoke alarm after returning from holidays or after being away 

for a prolonged period. The smoke alarm can be tested with the test button.

3.  The smoke alarm sounds as long as the test button is pressed down or as 

long as there is smoke in it.

4.  Make sure the battery is correctly positioned Replace battery if the smoke 

alarm makes no noise.

5.  Below the test button is a red diode that blinks 1-2 times per minute.  

It shows that the smoke alarm is working.

6.  Wipe the surface of the smoke alarm with 

a slightly moist cloth when needed. When 
cleaning house,  the smoke alarm may be 
vacuumed slightly as you do house cleaning.

Changing batteries

A normal battery lasts for about one year. About one month before the battery is 
completely discharged, the smoke alarm will start to emit short signals at about 
one-half minute intervals. It is then time to replace the battery. Once this is done 
the detector will start working again. 
Battery: 9V standard or alkaline battery, e.g., Duracell MN 1604,  
Eveready no. 22, 1222 or 216, Gold Peak 1604 P or Ultralife U9VL-J.
Always test the smoke detector after replacing the battery.
