517TCSB Series Photoelectric Type Residential Smoke
Alarms with Strobe for the Hearing Impaired,
AC Powered, 120V 60 Hz, with 9V Battery Backup
INTRODUCTION
The 517TCSB smoke alarms are photoelectric type alarms for use as evacu-
ation devices. Each alarm has a solid state piezo that emits a temporal 3
signal and a strobe to warn and alert the household to the presence of threat-
ening smoke.
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.
HOW YOUR SMOKE ALARM WORKS
The 517TCSB Series Smoke Alarm operates on the photoelectric light scatter
principle. The unit’s sensing chamber houses a light source and a light sen-
sor.
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 sec-
onds. 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 sen-
sor. 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.

READ CAREFULLY AND SAVE
· If the battery is low, a chirp will be sounded when the red LED flashes. If the
alarm is malfunctioning, or if the battery is missing, the chirp is sounded
without the red LED flashing. If AC power fails, the green LED will turn off.
· The test knob of your alarm simulates actual smoke conditions.
NOTE: Tandem Interconnect Models.
· When testing one alarm, the alarm that is activated will flash the red indica-
tor light emitting diode and sound its alarm horn, all other units will sound the
alarm horn with red indicator light emitting diodes remaining off.
FIRE PROTECTION PLAN
This Smoke Alarm can quickly alert you to the presence of smoke—it can-
not 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 ulti-
mate 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 in-
stalled 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.
(c) Make sure your children know what to do in case of fire and teach
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 leak-
ing 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.
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 effec-
tive fire safety program:
a. Install smoke alarms properly following the instructions in this
manual. Keep your smoke alarms clean. Test your alarm weekly
and repair or replace 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.
HOW TO TELL IF YOUR SMOKE ALARM IS
WORKING PROPERLY
· Your alarm is provided with an alarm horn and pulsating Light Emitting (indi-
cator) Diode, which pulses every 15-30 seconds, and a green AC power on
LED.
· When turning the test knob on the alarm to test 1, the red light will flash
rapidly, the horn will sound and the strobe will flash. Strobe will not oper-
ate without AC power.
