9.  If the smoke detector cover does not align, rotate 

the base and retighten the screws. 

10. Activate the battery. With the cover open, remove 

and reinstall the battery, so the terminals on the 

battery match the terminals on the smoke detector. 

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 detector 

may beep briefly when user installs the battery – this 

is normal. Once the battery is installed, the red 

power indicator light (behind the test button) will 

flash once per minute to show the smoke detector is 

working.

11.  Close the cover completely.

12. Test the smoke detector. Press and hold the test 

button on the cover of the unit until the smoke 

detector sounds (the smoke detector may continue 

to sound for a few seconds after button is released). 

(See Figure 3) During testing, user will hear a loud, 

repeating horn pattern: three beeps, pause, three 

beeps, pause. If the smoke detector does not sound 

during testing, call Uline Customer Service at  

1-800-295-5510.
