TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you activate the battery
and test the Smoke Alarm.
1. Install the battery so the terminals
on the battery match the terminals
on the Smoke Alarm. Match “+” to
“+” and “-” to “-.” Push the battery in
until it snaps in securely and cannot
be shaken loose. If the battery is
not snapped in completely, the unit
cannot receive battery power.
2. Push and hold test button until the
alarm sounds:
3 beeps, pause, 3 beeps, pause.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install a new battery
and test again. If the Smoke Alarm still
does not alarm, replace it immediately.
3. Using needle-nose pliers or a utility
knife, detach one locking pin from
the mounting bracket.
4. 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 wher
e 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: • Needle-nose pliers or utility knife • 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 or a utility knife.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the lock,
and pr
y 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 compart-
ment, close the battery door and
reinsert locking pin in lock.
4. Reattach the Smoke Alarm
to the mounting bracket.
When replacing the battery, always
test the Smoke Alarm before re-
locking 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.
• 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 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.
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”).
