- Boat Use 

Ionization Smoke Alarms are generally more effective at detecting flaming 

fires, which consume combustible materials rapidly and spread quickly. 

Sources of these fires may include paper burning or a grease fire.  

Photoelectric Smoke Alarms are generally more effective at detecting 

smoldering fires, which smolder for hours before bursting into flame. Sources 

of these fires may include cigarettes burning in couches or bedding. 

For Maximum protection, use both types of smoke alarms on each level 

of your home.

Smoke Alarm Features: 

• Listed to UL 10/1/99 smoke alarm standard for Residential and 

Recreational Vehicle. It meets NFPA 302 and U.S. Coast Guard 

Standards for use on Boats. 

•  Distinctive horn sound pattern. Loud 85-decibel alarm horn.  

•  Test button checks smoke alarm functions  

•  Alarm mute Models(S/SLL) feature Mute/Test button used to temporarily 

silence the alarm during ventilation. Alarm automatically resets.  

IMPORTANT SAFETY INFORMATION                                         

READ AND SAVE THESE INSTRUCTIONS 

•  Caution -This smoke alarm is not designed for buildings, which require 

complete fire alarm systems. Buildings of this type include but are not 

limited to hotels, motels, dormitories, hospitals, nursing homes and group 

homes. This applies to single-family homes that have been converted for 

any of these uses.  

   WARNINGS and CAUTIONS  

•  Smoke Alarms can only work if they are properly located, installed, 

and maintained, and if smoke reaches them. They are not 

foolproof. 

• 

This Alarm meets the 10/1/1999 UL standard for a new horn "alarm" 

pattern for smoke alarms. This sound is different than other Smoke 

Alarms you may have installed or may have heard in other locations. 

You must test this alarm and educate all members and guests of the 

residence or business of this different horn pattern. 

• 

Different Smoke Alarm Sounds. If this unit replaces another 9 volt 

smoke alarm or is being used for additional protection where other 

smoke alarms are present, than everyone who might hear this alarm 

must be made aware of the different smoke alarms horn sounds. 

•  Smoke Alarms cannot work without power. Battery operated units 

cannot work if the batteries are missing, disconnected or dead, if the 

wrong type of batteries are used, or if the batteries are not installed 

correctly AC units cannot work if the AC power is cut off by an electrical 

fire, an open fuse, a circuit breaker or any other reason. If you are 

concerned about the limitations of battery or AC power, install both types 

of units  

•  Smoke Alarms cannot detect fires if the smoke does not reach 

them. Anything preventing smoke from reaching the alarm may delay, or 

prevent an alarm. A smoke alarm cannot detect fire in the walls, 

chimney or roof unless and until a significant amount of smoke reaches 

the alarm. A closed door may prevent smoke from reaching an alarm on 

the other side of the door. Smoke alarms may not sense fire on another 

level or floor of a residence. That is why you should install alarms on all 

levels and in each sleeping area of a residence. When possible install 

interconnected alarms Interconnected units may provide earlier warning 

than stand-alone units since all units alarm when one detects smoke.  

• 

Smoke Alarms may not be heard. Though the alarm horn in this unit 

meets or exceeds current UL standards, it may not be heard for many 

reasons These include, but are not limited to: the unit is located outside 

a closed or partially closed door, residents recently consumed alcohol or 

drugs, the alarm is drowned out by other noise like the TV, stereo, 

traffic, weather, air conditioner or other appliances, residents are hearing 

impaired or sound sleepers. 

•  Smoke alarms have a limited life and are not foolproof. Smoke 

alarms will wear out over time like any appliance. Test your alarm at 

least once per week Always replace detectors immediately if they are 

not working properly, if they display any type of problem or prior to 10 

years of use. They are not a substitute for property or life insurance  

•  Smoke alarms may not have time to alarm before the fire causes 

damage, injury or even death. Examples of this include persons 

smoking in bed, children playing with matches or lighters, fires caused 

by violent explosions, natural causes like lighting, arson, escaping gas, 

overloaded electrical circuits, carelessness or by other safety hazards  

•  Never disconnect the battery to silence the alarm.  

•  This unit will not alert hearing-impaired residents. Special Alarms 

with flashing strobe lights are needed for the hearing impaired.  

• 

This is a single station alarm. Do not attempt to connect this to any 

other device 

• 

Do not install this alarm over an electrical box. Do not use this 

detector as a replacement for an AC or AC/DCsmoke alarm. Only use

as an additional alarm for greater protection or as a replacement for a       

battery operated smoke alarm.  

Series SA-668 Smoke Alarms are single station alarm devices and should 

not be connected to other detection units. This equipment should be installed 

in accordance with the National Fire Protection Association's Standard No 72 

and NFPA 302 if installed on a boat. 

•  Caution -Do not paint this unit. Paint may clog the openings to the 

sensing chamber and will prevent the unit from working properly.  

•  Caution -Do not stand too close to the unit when testing, silencing or 

during an alarm as the loud horn could damage your hearing. When 

testing move away when the horn starts sounding.  

•  Caution -This smoke alarm may not give adequate warning to those with 

physical limitations of any kind. Additional measures should be taken to 

insure their safe evacuation if a fire does occur. Install a professional fire 

alarm system that is connected to a call center. If possible, keep them on 

the ground level with more than one escape route available to them.  

•  Caution -Smoke alarms sound their horns when they detect smoke. They 

do not detect heat, flame or gas. They will not operate if smoke does not 

reach them.  

Practice Fire Safety  

Putting up smoke alarms is just one part of protection against fires. You must 

also reduce the chances of a fire starting and have a plan that you have 

practiced for everyone escaping if a fire does occur. 

Escape Planning  

•  Make a floor plan indicating all doors and windows and plan at least two 

escape routes from each room. Upper story rooms may require a rope or 

chain ladder for safe escape.  

•  Have a meeting and discuss your escape plan, showing everyone what to 

do in case of fire.  

•  Determine a meeting location outside the building/RV/Boat where you can 

safely meet if a fire does occur.  

• Familiarize everyone with the sound of this smoke alarm and all other 

smoke alarms in the building/RV/Boat. Train everyone to safely leave the 

building/RV/Boat when they hear the smoke alarm(s).  

•  Update and practice your escape plan at least every six months. Inform 

guests and others of your plan and meeting place.  

•  Teach everyone how to check doors and not to open them if they are hot. 

Also to stay low and not to breath smoke, fumes or gases.  

What to do when the alarm sounds.  

Warning 

-Never ignore any alarm. If the alarm sounds and you are not 

absolutely certain of the source of the smoke, get everyone out of the 

house/RV/Boat immediately.  

•  Leave immediately by your plan of escape. Every second counts, do not 

waste time getting dressed (except life vests if needed) or picking up 

valuables. 

•  Feel doors before opening them to see if they are hot. If a door is cool, 

open it slowly and check for fire and heat before you proceed. Do not 

open a hot door - use an alternate escape route.  

•  Stay close to the floor if air is smoky, Take short shallow breaths through a 

wet cloth if possible.  

•  Once outside, go to your selected meeting place and make sure everyone 

is there.  

• Call the Fire Department from outside of the building with the activated 

alarm, at a safe location-  

• 

Do not return to your home until fire officials say that it is safe.  

SMOKE ALARM PLACEMENT 

For your information the National Fire Protections Association's 

Standard reads as follows: 

"2-2 111 Smoke detectors shall be installed outside of each 

separate sleeping area in the immediate vicinity of the bedrooms 

and on each additional story of the family living unit including 

basements and excluding crawl spaces and unfinished attics. In 

new construction a smoke detector shall be installed in each 

sleeping room"  

"2-22 1 In new construction, where more than one smoke detector is 

required by 2-2 1, they shall be so arranged that operation of any 

smoke detector shall cause the alarm in all smoke detectors within 

the dwelling to sound"  

IMPORTANT SAFETY INFORMATION 

READ AND SAVE THESE INSTRUCTIONS 

"A-2521 Smoke Detection - Are more Smoke Detectors Desirable? 

The required number of smoke detectors might not provide reliable 

early warning protection for those areas separated by a door from 

the areas protected by the required smoke detectors For this 

reason it is recommended that the householder consider the use of 

additional smoke detectors 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 detectors. The installation of smoke detectors in 

kitchens, attics (finished or unfinished) or garages is not normally 

recommended as these locations occasionally experience 

conditions that can result in improper operation".  

Additionally, the California State Fire Marshal states that the 

minimum number of required smoke alarms in not enough to give: 

the earliest warning under all conditions. The California Sate Fire 

Marshal states: "Early warning detection is best achieved by the 

installation of fire detection equipment in all rooms and areas of the 

household as follows: smoke alarm installed in each separate 

sleeping area (in the vicinity, by outside bedrooms), and heat or 

smoke alarms in the living rooms, dinning rooms, bedrooms, 

kitchens, hallways, finished attics, furnace rooms closets, utility and 

storage rooms, basements, and attached garages" 

IMPORTANT!

Additional local building and regulatory codes may apply in your 

area Specific requirements for smoke alarm installation vary from 

state to state and from area to area. Check with you local Fire 

Department for current requirements where you live If you install 

AC or AC/DC units, it is recommended that they be interconnected 

for added protection

.  

Smoke Alarm Placement in Single Family Dwellings 

Minimum coverage, as recommended by the National Fire 

Protection Association (NFPA), is one smoke alarm on every floor, 

in every sleeping area, and in every bedroom. In new construction, 

the smoke alarms must be AC powered and interconnected. See 

above for details  

For added coverage, it is recommended that you install a smoke 

alarm in all rooms, halls, storage areas, finished attics and 

basements where temperatures normally remain between 40 F and 

100 F (4.4 C and 37.8 C). Make sure no door or other obstacle 

could keep smoke from reaching the alarm  

See home drawing for further information. 

Install Smoke Alarms:  

•  On every level of your home, including finished attics and 

basements. 

•  Inside every bedroom, especially if occupants sleep with the door 

partly or completely closed. 

CONSUMER: PLEASE READ 

AND SAVE THIS MANUAL 

INSTALLER: Please leave this manual 

with the smoke alarm 

•  In basements, install a smoke alarm on the ceiling at the     

bottom of the stairwell.  

•  Install smoke alarms on peaked, cathedral, or gabled ceilings 3 

feet from the highest point (measured horizontally). Install a smoke 

alarm in each room that is divided by a partial wall (either coming 

down from the ceiling at least 8 inches or coming up from the floor).
