Optional Locking Features, Weekly Testing

OPTIONAL LOCKING FEATURES

The optional locking features are designed to discourage unauthorized removal of the batteries or Alarm. It is not necessary to activate the locks in single-family households where unauthorized battery or Alarm removal is not a concern.

This Smoke/CO Alarm has two separate locking features: one to lock the battery compartment, and the other to lock the Smoke/CO 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 pry the pin out of the lock.

TO LOCK THE BATTERY COMPARTMENT

Do not lock the battery compartment until you activate the battery and test the Smoke/CO Alarm.

1.Install the batteries before attaching the Alarm to the bracket. Insert the two (2) AA batteries (included) into the battery compartment. Match the terminals on the end of the battery with the terminals on the unit. Match “+” to “+” and “-” to “-.” If the batteries are not fully inserted, the unit cannot receive battery power.

2.Push and hold Test/Silence button until the alarm sounds.

If the unit does not alarm during testing, DO NOT lock the battery compartment! Install new batteries and test again. If the unit 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/CO Alarm.

TO UNLOCK THE BATTERY COMPARTMENT

1. Remove the Smoke/CO 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/CO Alarm to the mounting bracket.

When replacing the batteries, always test the Smoke/CO Alarm before relocking the battery compartment.

TO LOCK THE MOUNTING BRACKET

1.Using needle-nose pliers or a utility knife, detach one locking pin from the mounting bracket.

2.Insert the locking pin through the hole on the back of the Smoke/CO Alarm as shown in the diagram.

3.When you attach the Smoke/CO Alarm to the mounting bracket, the locking pin’s head will fit into a notch on the bracket.

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/CO Alarm away from the bracket by pushing up on the screwdriver and turning the Smoke/CO Alarm counterclockwise (left) at the same time.

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). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.

•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/CO Alarm.

You can test this Smoke/CO Alarm: Press and hold the Test/Silence button 3-5 seconds until unit starts to alarm.

During testing, you will see and hear the following sequence:

•The Horn will sound 3 beeps, pause, 3 beeps. The Power/Smoke LED flashes Red and the CO LED will be Off.

•Next the Horn will sound 4 beeps, pause, 4 beeps. The Power/Smoke LED will be Off and the CO LED flashes Red.

If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.
