517FH Series 135

°

F Fixed Temperature Heat Detector

AC Powered, 120V 60 Hz with Battery Backup

INTRODUCTION

The 517FH Heat Detector is for use as an evacuation device in

residential applications.  Each alarm has a solid state piezo that
emits a temporal 3 signal to warn and alert the household to the
presence of threatening heat.

Your alarm is designed to detect heat that results from an ac-

tual fire.  Heat detectors are intended for use as supplements to
smoke alarms.  This unit cannot detect smoke or other toxic gases,
therefore, do not rely solely on this heat detector to provide a warn-
ing of a fire.

NOTE:

  In the event AC Power fails, a 9v battery will provide proper

alarm operation for a minimum of a 24-hour period.

HOW TO TELL IF YOUR HEAT DETEC-
TOR IS WORKING PROPERLY

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

If the battery is low, a chirp will be emitted when the red LED
flashes.  If the alarm is malfunctioning, or if the battery is miss-
ing, the chirp is sounded without the red LED flashing.  If AC
power fails, the green LED will turn off.

To test your heat detector, direct a hair dryer at the sensor ele-
ment (silver disk) at a 4-6” distance.  Alternatively, a cordless
soldering iron may be applied to sensor element.  The unit will
return to normal standby mode once the disk cools down.  A
cold damp rag or sponge may used to quickly cool the sensor.

NOTE

:  Tandem Interconnect Models.

When testing one alarm, the alarm that is activated will flash the
red indicator light and sound its alarm horn.  All other units will
sound the alarm horn with their red indicator lights remaining
off.  The relays will also activate on all units in tandem on mod-
els equipped with the relay option.

FIRE PROTECTION PLAN

Please note that there are hazards against which heat detection

may not be effective, such as smoking in bed, explosions, when a
closed door separates the alarm from the source of the fire, 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.
(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.

READ CAREFULLY AND SAVE

(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.

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

Putting up heat detectors and 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 and heat detectors properly follow-

ing the instructions in the product’s manual.  Keep your
alarms clean.  Test your alarm monthly and repair or re-
place 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 com-
bustible 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 family, 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 bed-
room without opening the door.

•••••

Teach children what the smoke alarm or heat detection 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.
