TOOLS YOU WILL NEED:

This unit is designed to be mounted

on the ceiling, or on the wall if necessary.

•Pencil

•Drill with 3/16” (5 mm) drill bit

•Standard flathead screwdriver

•Hammer

•Pliers to activate optional “tamper-resistant” locking features

FOLLOW THESE SIMPLE STEPS!

If you want to lock the battery drawer, or lock the Smoke Alarm to the mounting bracket, please read the “Optional Locking Features” section before you begin installation.

1.Hold base firmly and twist the mounting bracket counterclockwise to separate it from the base.

2.Hold the mounting bracket against the ceiling (or wall) so the vertical mounting slot is aligned in the 12 o’clock position and trace around the inside of the mounting slots (vertical and horizontal mounting).

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 the center of the oval outlines you traced.

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.Attach the mounting bracket to the ceiling or wall.

7. Install the battery (included). Open the battery drawer. Match the terminals on the end of the battery with the terminals on the unit. 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.

NOTE: After you install the battery, the power indicator light may flash. (If the unit alarms, the light will blink rapidly, and the horn will repeatedly sound 3 beeps, pause, 3 beeps.)

8.Attach the Smoke Alarm to the mounting bracket. Line up the guides on the alarm’s base with the guides on the mounting bracket. When guides are lined up, turn the base clockwise (right) until it snaps into place.

NOTE: Once the Smoke Alarm is snapped onto the mounting bracket, you can rotate the Smoke Alarm to adjust the align- ment.

9.Test the Smoke Alarm. See “Weekly Testing.”

WEEKLY TESTING

•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/Silence button is the recommended way to test this Smoke Alarm. Press and hold the Test/Silence button on the cover of the unit until the alarm sounds and the Escape Light® turns on (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 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. The Escape Light® will turn on. LED flashes once every second.

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”).
