CLEANING 

Clean the smoke alarm at least once a month to remove dust, dirt, or
debris. Always turn off power to smoke alarm before cleaning.

Using the soft brush or wand attachment to a vacuum cleaner, vacuum all

sides and cover of smoke alarm. Be sure all the vents are free of debris.

If necessary, turn off power and use a damp cloth to clean smoke alarm

cover.

IMPORTANT: Do not attempt to remove the cover or clean inside the smoke

alarm. THIS WILL VOID YOUR GUARANTEE.

REPAIR 

CAUTION: Do not attempt to repair this smoke alarm.

Doing so will void your guarantee.

If smoke alarm is not operating properly, see “Troubleshooting”. If neces-
sary and if still under guarantee, return smoke alarm to Sensotec. Pack it
in a well-padded carton and send, postage prepaid to Sensotec address at
the end of this manual.

If the smoke alarm is no longer under guarantee, have a licensed
electrician replace the smoke alarm immediately with a comparable
Firex brand smoke alarm.

PRACTICE FIRE SAFETY

If the smoke alarm sounds its alarm horn, and you have not pushed
the test button, it is warning of a dangerous situation. 
Your immediate response is necessary. To prepare for such occur-
rences, develop family escape plans, discuss them with 
ALL household members, and practice them regularly. 

Expose everyone to the sound of a smoke alarm and explain what
the sound means. 

Determine TWO exits from each room and an escape route to the
outside from each exit. 

Teach all household members to touch the door and use an alter-
nate exit if the door is hot. INSTRUCT THEM NOT TO OPEN THE
DOOR IF THE DOOR IS HOT.

Teach household members to crawl along the floor to stay below
dangerous smoke, fumes, and gases.

Determine a safe meeting place for all members outside the building.

WHAT TO DO IN CASE OF A FIRE 

1. Don’t panic; stay calm.

2. Leave the building as quickly as possible. Touch doors to feel if

they are hot before opening them. Use an alternate exit if neces-
sary. Crawl along the floor, and DO NOT stop to collect anything. 

3. Meet at a pre-arranged meeting place outside the building. 

4. Call the fire brigade from OUTSIDE the building.

5. DO NOT GO BACK INSIDE A BURNING BUILDING. Wait for the

fire brigade to arrive. 

These guidelines will assist you in the event of a fire. However, to
reduce the chance that fires will start, practice fire safety rules and
prevent hazardous situations.
