First Alert SMOKE AND FIRE ALARM - Manual (Page 4)

• NEVER use an open flame of any kind to test this unit. You might
accidentally damage or set fire to the unit or to your home. The
built-in test switch accurately tests the unit’s operation as
required by Underwriters Laboratories, Inc. (UL). If you choose
to use an aerosol smoke product to test the Smoke Alarm, be
certain to use one that has been Listed to Underwriters
Laboratories, Inc. Safety Standards, and use it only as directed.
Use of non-UL Listed products or improper use of UL Listed
products may affect the Smoke Alarm’s sensitivity.
• If the Alarm ever fails to test properly, replace it immediately.
Products under warranty may be returned to the manufacturer
for replacement. See “Limited Warranty” for details.
• DO NOT stand close to the alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing. When
testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke Alarm. Press and hold the test button on the cover of the unit
until the alarm sounds (the unit may continue to alarm for a few seconds
after you release the button). If it does not alarm, make sure the unit is
receiving power (LED will flash approximately once a minute indicating it
has power); and test it again. If it still does not alarm, replace it
immediately. During testing you will hear a loud, repeating horn pattern:
3 beeps, pause, 3 beeps, pause.
WEEKLY TESTING
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but
there are a few simple things you must do to keep it working properly.
Use only the replacement batteries listed below. The unit may not
operate properly with other batteries. Never use rechargeable
batteries since they may not provide a constant charge.
• Test it at least once a week.
• Clean the Smoke Alarm at least once a month; gently vacuum off
any dust using your household vacuum’s soft brush attachment, and
test the Smoke Alarm after cleaning. Never use water, cleaners or
solvents since they may damage the unit.
• If the Smoke Alarm becomes contaminated by excessive dirt, dust
and/or grime, and cannot be cleaned to avoid unwanted alarms,
replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See
“Locations to Avoid For Smoke Alarms” for details.
• When the battery becomes weak, the Smoke Alarm unit will “chirp”
approximately once a minute (the low battery warning). This low
battery warning should last for up to 30 days, but you should replace
the battery immediately to continue your protection.
Choosing a replacement battery:
Your Smoke Alarm requires one standard 9V battery. The following
batteries are acceptable as replacements: Duracell #MN1604, (Ultra)
#MX1604; Eveready (Energizer) #522. You may also use a Lithium
battery like the Ultralife U9VL-J for longer service life between battery
changes. These batteries are available at many local retail stores.
Actual service life depends on the Smoke Alarm and the environment in
which it is installed. All the batteries specified above are acceptable
replacement batteries for this unit. Regardless of the manufacturer’s
suggested battery life, you MUST replace the battery immediately once
the unit starts “chirping” (the “low battery warning”).
