This unit is designed to be mounted on the ceiling, or on the wall if necessary.

Drill with 3/16” (5 mm) drill bit

•

Standard/Flathead screwdriver

•

Hammer

1. Hold base firmly and pull up on cover tab marked 

“OPEN HERE.” This will open the hinged cover. The cover 
may unsnap from the base if it's opened too far. This will not 
damage the unit—the cover hinge snaps back into place 
easily.

2. Hold the smoke alarm base against the ceiling (or wall) and 

make a mark at the center of each of the mounting slots with 
a pencil.

3. Put the unit where it won’t get covered with dust when you 

drill the mounting holes.

4. Using a 3/16” (5 mm) drill bit, drill a hole through each pencil 

mark.

5. Insert the plastic screw anchors (in the plastic bag with 

screws) into the holes. Tap the screw anchors gently with a 
hammer, if necessary, until they are flush with the ceiling or 
wall.

6. Tighten the screws (provided) into the screw anchors, then 

loosen them two turns. 

7. Fit the smoke alarm over the screw heads as shown. Close 

cover.

8. If the smoke alarm cover does not line up the way you want it, 

rotate the base and re-tighten the screws.

9. Activate the battery. With the cover open, remove and reinstall 

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. The smoke alarm may 
beep briefly when you install the battery—this is normal.

 

10. Close the cover all the way.

11. Test the smoke alarm. See “Weekly Testing.” 

 

If it does not alarm 

during testing, make sure the unit is receiving power. Make sure the battery is fresh, and installed correctly, then test it 
again. If it still does not alarm, replace it immediately.

 

Press and hold the test button on the cover of the unit for 5-20 seconds, or until the alarm sounds (the unit may continue 
to alarm for a few seconds after you release the button). 

 

The Remote Flashlight Test method works best on ceilings up to 15 feet high. Wave a flashlight with a 
strong beam rapidly back and forth in a straight line across the test button—at least 3 feet in each 
direction—until the alarm sounds. If this method does not work, use the test button to make sure the 
alarm is working. If it alarms, try the Remote Flashlight Test method again, making sure to wave the 
flashlight very rapidly across the test button.

The Escape Light

 

®

 

 should always shine during testing. If the horn sounds, but the light does not shine, install a fresh 

alkaline battery in the “Alkaline Only” battery slot, make sure the bulb is not burned out, and re-test. If the light still does 
not shine, the unit should be replaced.

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.

•

Test it at least once a week.

•

Test units used in RVs after the vehicle has been in storage, before every trip, and once a week while in use. 
Failure to test units used in RVs as described may remove your protection.

•

Clean the smoke alarm at least once a month; gently vacuum off any dust using your household 
vacuum’s soft brush attachment. 1. Open the cover and disconnect the battery. 2. GENTLY vacuum the 
inside of the cover and the sensor chamber. 3. Reconnect the battery. 4. Close the smoke alarm, and vac-
uum the outside of the cover. 5. Test the smoke alarm. 

 

•

Relocate the unit if it sounds frequent unwanted alarms. See “Where Not To Install Smoke Alarms.” 

•

When the battery becomes weak, the smoke alarm unit will “chirp” about once a minute (the low battery warn-
ing). This low battery warning should last for 30 days, but you should replace the battery immediately to con-
tinue your protection.

 

Your smoke alarm requires one standard 9V battery. The following batteries are 

acceptable as replacements: Eveready #216, (Energizer) #522, #1222; Duracell #MN1604; Gold Peak #1604P, #1604S; 
Rayovac 1604, D1604. 

 

Your smoke alarm requires two 9V batteries—one to power the alarm, and an 

alkaline battery to power the Escape Light

. The following batteries are acceptable as replacements to power the alarm: 

Eveready Energizer #522, #1222; Duracell #MN1604; Rayovac 1604, D1604. The following batteries are acceptable as 
replacements to power the Escape Light

: Eveready Energizer #522; Duracell #MN1604.

 

You may also use a Lithium battery like the Ultralife U9VL-J for longer service life between battery changes. 

All batteries listed here are available at many local retail stores.

 

Most carbon zinc batteries have an average service life of 1 year; most alkaline batteries have an average service life 
of 1-2 years; most Lithium batteries have an average service life of 6-10 years. 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”).
