TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the batteries
and test the Smoke Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Smoke Alarm still
does not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then push
the locking pin through the hole near
the battery door latch on the back of
the Smoke Alarm.
OPTIONAL LOCKING FEATURES
TO LOCK THE MOUNTING BRACKET
1. Using needle-nose pliers,
detach one locking pin from
the mounting bracket.
2. Insert the locking pin through
the hole on the back of the
Smoke Alarm as shown in the
diagram.
3. When you attach the Smoke
Alarm to the mounting bracket,
the locking pin’s head will fit
into a notch on the bracket.
The optional locking features are designed to prevent unauthorized removal of the battery or alarm. It is not necessary to activate the locks in
single-family households where unauthorized battery or alarm removal is not a concern.
These Smoke Alarms have two separate locking features: one to lock the battery compartment, and the other to lock
the Smoke Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: U Needle-nose pliers U Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the lock,
and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
1. Remove the Smoke Alarm from
the mounting bracket. If the unit
is locked to the bracket, see the
section “To Unlock the Mounting
Bracket.”
2. Insert a flathead screwdriver under
the head of the locking pin, and
gently pry it out of the battery
compartment lock. (If you plan to
relock the battery compartment,
save the locking pin.)
3. To relock the battery compartment,
close the battery door and reinsert
locking pin in lock.
4. Reattach the Smoke Alarm to the
mounting bracket.
When replacing the batteries,
always test the Smoke Alarm before
relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET
1. Insert a flathead screwdriver into
the rectangular cut-out on the
mounting bracket nearest to the
locking pin.
2. Pry the Smoke Alarm away from
the bracket by pushing up on
the screwdriver and turning the
Smoke Alarm counterclockwise
(left) at the same time.
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.
U Test it at least once a week.
U 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.
U 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.
U Relocate the unit if it sounds frequent unwanted alarms. See
“Locations to Avoid For Smoke Alarms” for details.
U 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 2 “AA” Energizer E91 batteries. 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”).
To replace the batteries (without removing Alarm from the ceiling
or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
U 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).
U 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.
U 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.
