INTRODUCTION

The 517T Series Smoke Alarm is a Photoelectric Type Alarm for use as an evacuation device. Each alarm has a solid state piezo that emits a temporal 3 signal to warn and alert the household to the presence of threatening smoke.

The 517TH Series Smoke Alarm is a combination photoelectric alarm and heat detector. The heat detector is an isolated 135ºF fixed temperature detector.

The 517TC Series Smoke Alarm also has a form A / form C relay contact.

Your Photoelectric alarm is designed to detect the smoke that results from an actual fire. Consequently, it is uncommon for household smoke such as cigarette smoke or normal cooking smoke to cause an alarm. NOTE: Loss of electrical input will cause the alarm not to function. For maximum safety you should install both battery operated and AC powered smoke alarms.

HOW YOUR SMOKE ALARM WORKS

The 517T Series Smoke Alarm operates on the photoelectric light scatter principle. The units sensing chamber houses a light source and a light sensor.

The darkened sensing chamber is exposed to the atmosphere and designed to permit optimum smoke entry from any direction while rejecting light from outside the alarm.

The light source is an infrared (invisible) LED which pulses every 8 seconds. The light sensor is a photodiode matched to the light frequency of the LED light source.

Under normal conditions, the light generated by the pulsing infrared LED is not seen by the light sensor, as it is positioned out of the direct path of the light beam. When smoke enters the sensing chamber, light from the pulsing LED light source is reflected by the smoke particles onto the photodiode light sensor. At the first sighting of smoke, the alarm is put into a pre-alarm mode. This is indicated by a rapidly flashing LED on the face of the alarm. Once the light sensor confirms smoke for 2 consecutive pulses inside the chamber, the light sensor produces the signal necessary to trigger the alarm.

This technique of verifying the smoke condition, combined with a 5-to-1 signal-to-noise ratio, substantially reduces the possibility of nuisance alarms.

· When turning the test knob on the alarm to test 1 the red light emitting diode should glow steady RED and horn should sound. On some units, the red LED will flash rapidly instead of glowing steady. If AC power fails, the green LED will turn off.

NOTE: Tandem Interconnect Models.

· When testing one alarm, the alarm that is activated will light the red indicator light emitting diode and sound its alarm horn, all other units will sound the alarm horn with red indicator light emitting diodes remaining off.

· The test knob of your alarm simulates actual smoke conditions.

FIRE PROTECTION PLAN

This Smoke Alarm can quickly alert you to the presence of smokeit cannot prevent fire. Please note that there are hazards against which smoke detection may not be effective, such as smoking in bed, explosions, when a closed door separates the alarm from the source of the smoke, etc. The ultimate responsibility for fire protection rests solely on you.

1. To minimize fire hazardsavoid improper storage of flammable liquids

and dont leave small children home alone.

2. Bedroom doors should be closed while sleeping if a smoke alarm is

installed in the bedroom. They act as a barrier against heat and smoke.

3. Establish an escape plan:

(a) Post a detailed floor plan depicting the chosen escape routes.

(b) Each bedroom should have at least two escape routes.

them to follow the escape plan you have posted. (d) Agree on an outside meeting place. (e) Conduct fire drills at least twice a year. (f) Be sure each member of the family is familiar with the smoke alarm

so they can react properly.

If the alarm should sound:

1. Never waste time dressing or gathering valuables. Follow the escape route and leave the house immediately.

2. Check bedroom doors before opening. If the door is hot or smoke is leaking in around the edgesDO NOT OPENuse the alternate escape route.

3. If there is smoke in the escape routekeep close to the floor and take short breaths. If possible, cover your nose and mouth with a wet cloth.

4. Do not use your own telephonecall the Fire Department from your neighbors house.

5. Once out, do not re-enter your house, but proceed to your prearranged meeting place.

HOW TO TELL IF YOUR SMOKE ALARM IS WORKING PROPERLY

· Your alarm is provided with an alarm horn and pulsating Light Emitting (indicator) Diode, which pulses every 15-30 seconds, and a green AC power on LED on some models.

WHAT ELSE YOU CAN DO TO MAKE YOUR FAMILY SAFE FROM FIRES

Putting up smoke alarms is just the first step in protecting your family from fires. You also must reduce the chances that fires will start in your home and increase your chances of safely escaping if one does start. To have an effective fire safety program:

a. Install smoke alarms properly following the instructions in this

manual. Keep your smoke alarms clean. Test your alarm weekly and have it repaired or replaced it when it no longer functions. As

with any electronic product, alarms have a limited life, and alarms that dont work cannot protect you.

b. Follow safety rules and prevent hazardous situations:

· Use smoking materials properly; never smoke in bed.

· Keep matches and cigarette lighters away from children.

· Store flammable materials in proper containers and never use them near

open flames or sparks.

· Keep electrical appliances and cords in good working order and do not overload electrical circuits.

· Keep stoves, fireplaces, chimneys, and barbecue grills grease-free and make sure they are properly installed away from combustible materials.

· Keep portable heaters and open flames such as candles away from combustible materials.

· Do not allow rubbish to accumulate.

c. Develop a family escape plan and practice it with your entire fam-

ily, especially small children.

· Draw a floor plan of your home and find two ways to exit from each room. There should be one way to get out of each bedroom without opening the door.

· Teach children what the smoke alarm signal means, and that they must be prepared to leave the residence by themselves if necessary. Show them how to check to see if doors are hot before opening them, how to stay close to the floor and crawl if necessary, and how to use the alternate exit if the door is hot and should not be opened.

· Decide on a meeting place a safe distance from your house and make sure that all your children understand that they should go and wait for you if there is a fire.

· Hold fire drills at least every 6 months to make sure that everyone, even small children, know what to do to escape safely.

· Know where to go to call the fire department from outside your residence.

· Provide emergency equipment such as fire extinguishers and teach your family to use this equipment properly.

WHAT TO DO IF THERE IS A FIRE IN YOUR HOME

If you have prepared family escape plans and practiced them with your family, you have increased their chances of escaping safely. Review the following rules with your children when you have fire drills so everyone will remember them in a real fire emergency: a. Dont panic; stay calm. Your safe escape may depend on thinking

clearly and remembering what you have practiced.

b. Get out of the house following a planned escape route as quickly as

possible. Do not stop to collect anything or to get dressed.

c. Open doors carefully only after feeling to see if they are hot. Do not

open a door if it is hot; use an alternate escape route. d. Stay close to the floor; smoke and hot gases rise. e. Cover your nose and mouth with a cloth, wet if possible, and take short,

shallow breaths. f. Keep doors and windows closed unless you open them to escape. g. Meet at your prearranged meeting place after leaving the house. h. Call the Fire Department as soon as possible from outside your house.

Give the address and your name. i. Never re-enter a burning building. Contact your local Fire Department for more information on making your home safer from fires and about preparing your familys escape plans.

WHAT THIS SMOKE ALARM CAN DO

This alarm is designed to sense smoke entering its sensing chamber. It

does not sense gas, heat (except 517TH), or flames.

When properly located, installed, and maintained, this smoke alarm is designed to provide early warning of developing fires at a reasonable cost. This alarm monitors the air and, when it senses smoke, activates its builtin alarm horn. It can provide precious time for you and your family to escape from your residence before a fire spreads. Such an early warning, however, is possible only if the alarm is located, installed, and maintained as specified in this Users Manual.

NOTE: This smoke alarm is designed for use within single residential living units only; that is, it should be used inside a single-family home or one apartment of a multi-family building. In a multi-family building, the alarm may not provide early warning for residents if it is placed outside of the residential units, such as on outside porches, in corridors, lobbies, basements, or in other apartments. In multi-family buildings, each residential unit should have alarms to alert the residents of that unit. Alarms designed to be interconnected should be interconnected within one family residence only; otherwise, nuisance alarms will occur when an alarm in another living unit is tested.

IMPORTANT NOTE: WHAT SMOKE ALARMS CANNOT DO

Smoke alarms will not work without power. Battery-operated alarms will not work without batteries, with dead batteries, or if the batteries are not installed properly. AC powered alarms will not work if their AC power supply is cut off by an electrical fire, an open fuse or circuit breaker, or for any other reason. If you are concerned about the reliability of either the batteries or your AC power supply for any of the above reasons, you should install both battery and AC powered alarms for maximum safety.

Smoke alarms may not sense fire that starts where smoke cannot reach the alarms such as in chimneys, in walls, on roofs, or on

the other side of closed doors. If bedroom doors are usually closed at night, alarms should be placed in each bedroom as well as in the common hallway between them.

Smoke alarms also may not sense a fire on another level of a residence or building. For example, a second-floor alarm may not sense a first-floor or basement fire. Therefore, alarms should be placed on every level of a residence or building.

The horn in your alarm meets or exceeds current audibility requirements of Underwriters Laboratories. However, if the alarm is located outside a bedroom, it may not wake up a sound sleeper, especially if the bedroom door is closed or only partly open. If the alarm is located on a different level of the residence than the bedroom, it is even less likely to wake up people sleeping in the bedroom. In such cases, the National Fire Protection Association recommends that the alarms be interconnected so that an alarm on any level of the residence will sound an alarm loud enough to awaken sleepers in closed bedrooms. This can be done by installing a fire-detection system, by connecting alarms together, or by using radio frequency transmitters and receivers.

All types of smoke alarm sensors have limitations. No type of smoke alarm can sense every kind of fire every time. In general, alarms may not always warn you about fires caused by carelessness and safety hazards like smoking in bed, violent explosions, over-loaded electrical circuits, children playing with matches, escaping gas, improper storage of flammable materials, or arson.

NOTE: This alarm is not designed to replace special-purpose fire detection and alarm systems necessary to protect persons and property in non-residential buildings such as warehouses, or other large industrial or commercial buildings. It alone is not a suitable substitute for complete fire-detection systems designed to protect individuals in hotels and motels, dormitories, hospitals, or other health and supervisory care and retirement homes. Please refer to NFPA 101,The Life Safety Code, and NFPA 72 for smoke alarm requirements for fire protection in buildings not defined as households.

Installing smoke alarms may make you eligible for lower insurance rates, but smoke alarms are not a substitute for insurance. Home owners and renters should continue to insure their lives and property.

PLACEMENT OF SMOKE ALARMS

THIS EQUIPMENT SHOULD BE INSTALLED IN ACCORDANCE WITH THE NATIONAL FIRE PROTECTION ASSOCIATIONS STANDARD 72 (National Fire Protection Association, Batterymarch Park, Quincy, MA

02269).

For your information, the National Fire Protection Associations Standard 72, reads as follows:

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.

Where to Locate the Required Smoke Detectors in Existing Construction. The major threat from fire in a family living unit is at night when everyone is asleep. The principal threat to persons in sleeping areas comes from fires in the remainder of the unit; therefore, a smoke alarm(s) is best located between the bedroom areas and the rest of the unit. In units with only one bedroom area on one floor, the smoke alarms should be located as shown in Figure 1.
