If you choose to use an aerosol smoke product to test the smoke alarm, be certain to use 

one that has been Listed to Underwriters Laboratories, Inc. Safety Standards and use it 

only as directed. Use of non-UL Listed products or improper use of UL Listed products may 

affect the smoke alarm's sensitivity.

NUISANCE ALARM SILENCE FEATURE: 

This feature is to be used only when a known alarm 

condition, such as smoke from cooking, activates the smoke alarm. The smoke alarm Silence Feature 

is activated by pushing and releasing the Silence button on the smoke alarm cover while in alarm 

condition. The smoke alarm will automatically reduce sensitivity and the red LED will blink on approx. 

every 10 seconds to indicate the alarm is in the Silence mode. The smoke alarm will gradually 

regain normal sensitivity and sound the alarm if particles of combustion are still present. The 8-12 

minute Silence feature may be used repeatedly until the air has cleared, by pushing and releasing 

the Silence button again. Resetting the smoke alarm after a nuisance alarm is recommended.

NOTE:  If the Test button is pressed and held during the Silence mode, the smoke alarm will be 

tested normally. Upon the release of the Test button, the Silence mode will be restarted.

Before using the alarm Silence Feature, identify the source of smoke and be certain that 

safe conditions exist.

Clean the smoke alarm at least once a month

 to remove dust, dirt, insects or debris. Always 

turn off power to smoke alarm before cleaning. Using a soft brush or wand attachment to a vacuum 

cleaner, vacuum all sides and cover of smoke alarm. Be sure all the vents are free of debris.

BATTERY REPLACEMENT

The smoke alarm uses a 9 Volt battery. The battery should last for at least one year under normal 

operating conditions. The smoke alarm has a low battery indicator, an audible beep or chirp. It 

will operate at approx. 40 second intervals for a minimum of 7 days. When this indication occurs, 

replace the battery with an Alkaline type (Duracell MN1604, Energizer #522) or Lithium type (Ultralife 

U9VL-J) from your local retailer.

LITHIUM Battery Models only

 - The LITHIUM battery is warranted to last for 10 years under normal 

operating conditions. Replace the battery with only LITHIUM type: (ULTRALIFE: U9VL-J).
OPTIONAL BATTERY DRAWER TAMPER LOCKING PIN: To make your battery drawer tamper 

resistant, a locking pin has been provided (breakaway part on mounting bracket).
NOTE: If this feature has been activated, you will need to deactivate it by removing the battery 

drawer tamper pin located at side of battery drawer. Refer to Page 5.

Pull the QUICK DRAW

® 

battery drawer open and remove the battery. While observing polarity, push 

the replacement battery into the battery drawer until it is held securely in place. Carefully close  the 

battery drawer and reinstall the tamper pin.

Test the smoke alarm by pushing the TEST button on the smoke alarm cover until the alarm 

sounds, then release.

IMPORTANT: 

Under normal conditions, the test button should sound the alarm immediately after it 

is pressed. There are special conditions that, when you press the Test button, you will experience 

a delay of approx. 10-15 seconds before the alarm sounds. This delay occurs if the test button is 

pressed during a self-diagnostic period. This occurs: (1) Upon initial power up; (2) After battery 

replacement. Retest after 10-15 seconds.
