1. Smoke Alarm: What To Do When The Alarm Sounds

The smoke alarm pattern is three long beeps, a 1.5 second pause, and three long beeps repeating. The red LED blinks in time with the alarm pattern only on the alarm(s) that detected the hazard (initiating alarm).

NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

2. Carbon Monoxide Alarm: What To Do When The Alarm Sounds

NOTE: THIS IS NOT A CARBON MONOXIDE (CO) ALARM, BUT WILL RECEIVE AND TRANSMIT A CO ALARM SIGNAL FROM AN INTERCONNECTED CO OR COMBINATION SMOKE / CO ALARM.

The carbon monoxide (CO) alarm pattern is four quick beeps repeating every 5 seconds.

[Warning] ACTUATION OF YOUR CO ALARM INDICATES THE PRESENCE OF CARBON MONOXIDE (CO) WHICH CAN KILL YOU. IF ALARM SIGNAL SOUNDS:

  1. Operate the Test/Hush button. NOTE: Pressing the button on the initiating CO or combination smoke/CO unit in your system will silence the alarm notification, including all interconnected units. If the CO or combination smoke/CO unit goes into alarm mode again within six minutes, it is sensing high levels of CO which can quickly become a dangerous situation.
  2. Call your emergency services (Fire Department or 911). EMERGENCY PHONE #: _______________________
  3. Immediately move to fresh air--outdoors or by an open door/window. Do a head count to check that all persons are accounted for. Alert small children in the home as well as anyone else that might have difficulty recognizing the importance of the alarm sounding or that might have difficulty leaving the area without help. Do not reenter the premises or move away from the open door/window until the emergency services responders have arrived, the premises have been aired out, and your alarm remains in its normal condition.
  4. After following steps 1-3, if the alarm reactivates within a 24 hour period, repeat steps 1-3 and call a qualified appliance technician to investigate sources of CO from fuel burning equipment and appliances, and to inspect for proper operation of equipment.

If problems are identified during this inspection, have the equipment serviced immediately. Note any combustion equipment not inspected by the technician and consult the manufacturer's instructions, or contact the manufacturer directly for more information about CO safety and the equipment. Make sure that motor vehicles are not, or have not been, operating in a garage attached or adjacent to the residence. Never restart the source of a CO problem until it has been corrected. Never ignore the sound of the alarm! NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

10. Operation And Testing

This model meets the latest residential smoke alarm standards, which includes enhanced resistance to nuisance alarms from cooking.

Operation

The alarm is operating once it is activated and testing is complete (see "TESTING" below). When products of combustion (smoke) are sensed, the unit sounds a loud alarm. See Section 1 for alarm signal descriptions.

Testing

[Warning] Do not attempt to test this unit with retail "canned smoke" products. Those products are intended for use by trained professionals and produce inconsistent results when misused. Over-application of canned smoke can permanently damage the alarm.

SELF-TESTING

This model is equipped with internal, self-testing components that are always checking to ensure the device is operating as expected. (Weekly manual testing is still required. See below.)

MANUAL TESTING

NOTE: When pushing the Test button, use only your finger or thumb. Using any other instrument(s) (such as a broom handle) is strictly prohibited, as it may damage the alarm.

Test your alarm weekly by pressing and releasing the button quickly. A quick beep will confirm the button has been pushed followed by the test sequence. See Other Alarm Visual and Audible Indicators table. The alarm (and any interconnected units) will sound if the electronic circuitry, horn, and batteries are working. If the alarm does not sound, or gives erratic or low volume sound, the unit must be replaced.

[Warning] DUE TO THE LOUDNESS OF THE ALARM, ALWAYS STAND ABOUT 2.5 FEET AWAY FROM THE UNIT OR USE EAR PROTECTION WHEN TESTING.

[Warning] DO NOT USE AN OPEN FLAME TO TEST YOUR ALARM, YOU COULD DAMAGE THE ALARM OR IGNITE COMBUSTIBLE MATERIALS AND START A STRUCTURE FIRE.

Chirping

When End of Unit Life or Low Battery chirping begins, you can temporarily silence these chirps by pressing the button. Other fault/error chirps cannot be silenced. Take appropriate action as described in the Troubleshooting Guide.

[Warning] REPLACE UNIT AS SOON AS POSSIBLE WHEN IN END OF UNIT LIFE. SEVEN (7) DAYS AFTER END OF UNIT LIFE BEGINS, THE NOTIFICATIONS CANNOT BE SILENCED, AND SMOKE DETECTION CANNOT BE GUARANTEED. REPLACE IMMEDIATELY!

11. Recognizing Nuisance Alarms

Smoke Nuisance

This model meets the latest residential smoke alarm standards, which includes enhanced resistance to nuisance alarms from cooking.

HUSHTM: If you know why the alarm is sounding, and you can verify that it is not a life threatening situation, you can push the button on the initiating unit to silence the alarm for 8-10 minutes. If the smoke is not too dense, that unit, and all interconnected units will silence. After the HushTM period, the smoke alarm will automatically reset and sound the alarm if particles of combustion are still present. You can use HushTM repeatedly until the air has been cleared of the condition causing the alarm.

NOTE: Dense smoke will override HushTM and sound a continuous alarm. If no fire is present, check to see if one of the reasons listed in "Locations to avoid" may have caused the alarm. If a fire is discovered, get out and call the fire department or 911.

Cigarette smoke will not normally cause the unit to alarm, unless the smoke is blown directly into the alarm. Combustion particles from cooking may set off the alarm if it is located too close to a cooking appliance. Large quantities of combustible particles are generated from spills or when broiling. Using the fan on a range hood which vents to the outside (non-recirculating type) will also help prevent nuisance alarms from occurring by removing these combustible products from the kitchen.

Carbon Monoxide (CO) Nuisance

[Warning] This unit does not detect CO, but it will transmit a CO alarm signal from an interconnected CO or Smoke/CO combination alarm. It is impossible to determine the source of a CO alarm using sight or smell. Always consider a CO alarm event as dangerous.

12. Battery Backup

This alarm is powered with AC power, but also contains two replaceable AA backup batteries. Under normal conditions, fresh batteries will last at least one year.

In order to access the battery compartment, the wiring harness needs to be removed. To release the wiring harness, press down on the tab as shown in Figure 12-A.

Diagram Description (Figure 12-A): Shows how to release the wire harness by pressing down on a tab.

NOTE: Constant exposure to high or low humidity or temperatures may reduce battery life.

[Warning] THE ALARM IS SEALED AND THE COVER IS NOT REMOVABLE!

Low Battery

This alarm is equipped with a low battery monitor circuit. If the battery capacity is nearing the point where it can no longer provide adequate power for all alarm functions, the low battery condition will occur. See Troubleshooting Guide. The batteries must be replaced within 7 days of the first occurrence of the "Low Battery Warning" to provide continuous alarm detection.

Replace batteries with one of the following approved brands: Energizer E91, Gold Peak 15A or Golden Power GLR6A. These batteries can be purchased at your local retailer.

Diagram Description (Figure 12-B): Shows two AA batteries correctly inserted into the battery compartment.

[Warning] Use only the batteries specified. Use of different batteries may have a detrimental effect on the alarm. Do not mix old and new batteries. Do not mix alkaline, standard, or rechargeable batteries.

NOTE: Do not use lithium batteries in this unit. A good safety measure is to replace the batteries at least once a year, or at the same time you change your clocks for daylight saving time. Loss of AC power and a missing or improperly installed battery will render the unit inoperable.

[Warning] FAILURE TO PROPERLY CONNECT AC POWER AND INSTALL BATTERIES IN THE CORRECT ORIENTATION WILL PREVENT PROPER OPERATION OF THIS ALARM AND WILL PREVENT ITS RESPONSE TO FIRE HAZARDS.

13. Cleaning Your Alarm

Your Alarm Should be Cleaned at Least Once a Year

You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum cleaner hose and blowing or vacuuming through the openings around the perimeter of the alarm. The outside of the alarm can be wiped with a clean, dry cloth. Do not use water, detergents or cleaners as they may damage the alarm.

NOTE: Do not insert fingers or cleaning items under the shield during cleaning.

Diagram Description (Figure 13-A): Shows three images related to cleaning. The first shows wiping the exterior with a cloth. The second shows vacuuming through the openings. The third shows an 'X' indicating not to insert items under the shield.

If the alarm is in Fault mode, the alarm may be in need of cleaning. After cleaning, press the button. If the fault does not clear, the alarm needs to be replaced.

[Warning] REINSTALL THE ALARM AS SOON AS POSSIBLE TO ENSURE CONTINUOUS DETECTION.

14. Good Safety Habits

Develop and Practice a Plan of Escape

Prepare and practice a home escape plan twice a year, including drills at night. Know two ways out of every room (door & window) and identify a meeting place outside the home where everyone will gather once they have exited the residence. When two people have reached the meeting place, one should leave to call 911 while the second person stays to account for additional family members. Establish a rule that once you're out, you never re-enter under any circumstance!

15. Fire Prevention

Never smoke in bed or leave cooking food unattended. Teach children never to play with matches or lighters! Train everyone in the home to recognize the smoke alarm pattern and to leave the home using their escape plan when it's heard. Know how to do "Stop, Drop and Roll" if clothes catch on fire, and how to crawl low under smoke. Install and maintain fire extinguishers on every level of the home and in the kitchen, basement and garage.

NFPA (National Fire Protection Association)

Fire Safety in the Home:

NFPA 72 is intended to provide reasonable safety for persons in family living units. Reasonable fire safety can be produced through the following three-point program: (1) Minimizing fire hazards (2) Providing fire-warning equipment (3) Having and practicing an escape plan.

Smoke Detection – Are More Alarms Desirable?

The required number of smoke alarms might not provide reliable early warning protection for those areas separated by a door from the areas protected by the required smoke alarms. For this reason, it is recommended that the resident consider the use of additional smoke alarms for those areas for increased protection. The additional areas include the basement, bedrooms, dining room, furnace room, utility room, and hallways not protected by the required smoke alarms. The installation of smoke alarms in attics (finished or unfinished), garages, or within 6' of a heating or cooking appliance is not normally recommended, as these locations occasionally experience conditions that can result in improper operation. *

* Reference National Fire Protection Association (NFPA) standard 72

NFPA Standard 72 Recommendations:

For your information, the National Fire Protection Association's Standard 72 reads: Where required by other governing laws, codes, or standards for a specific type of occupancy, approved single and multiple-station smoke alarms shall be installed as follows:

  1. In all sleeping rooms and guest rooms
  2. Outside of each separate dwelling unit sleeping area, within 21 ft (6.4 m) of any door to a sleeping room, with the distance measured along a path of travel
  3. On every level of a dwelling unit, including basements
  4. On every level of a residential board and care occupancy (small facility), including basements and excluding crawl spaces and unfinished attics
  5. In the living area(s) of a guest suite
  6. In the living area(s) of a residential board and care occupancy (small facility)

California State Fire Marshal

Early warning fire detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows: A smoke alarm installed in each separate sleeping area (in the vicinity, but outside the bedrooms), heat or smoke detectors in the living rooms, dining rooms, bedrooms, kitchens, hallways, attics, furnace rooms, closets, utility and storage rooms, basements and attached garages.
