INTRODUCTION HD135

The HD135 Series heat alarm 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 heat alarm is designed to detect heat that results from an actual fire.  Heat

alarms 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 alarm to provide

warning of a fire.

HOW TO TELL IF YOUR HEAT ALARM IS WORKING PROPERLY

w

Your heat alarm is provided with an alarm horn and pulsating Light Emitting 

(indicator) Diode, which pulses every 30 seconds and a green  AC power on LED.

w

If the battery is low or missing, a chirp will be emitted when the red LED flashes.  

If the heat alarm is malfunctioning, the chirp is sounded without the red LED 

flashing.  If AC power fails, the green LED will turn off.

w

To test your heat alarm, direct a hair dryer at the sensor element (silver disk) at a 

4-6" distance.  Alternatively, a cordless soldering iron may be applied to the sensor 

element.  The unit will return to normal standby mode once the disk cools down.  A 

cold damp rag or sponge may be used to quickly cool the sensor.

NOTE:  TANDEM INTERCONNECT MODELS.

w

When testing one heat alarm, the heat 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 models equipped with the relay option.

FIRE PROTECTION PLAN: WHAT YOU CAN DO TO MAKE YOUR 

FAMILY SAFE FROM FIRES

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 heat

alarm from the source of the fire, etc.  The ultimate responsibility for fire protection

rests solely on you.  

Installing heat 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 and heat alarms properly following the instructions in this 

manual.  Keep your units clean.  Test your alarm weekly and have unit 

repaired or replace alarm when it when it no longer functions.

As with any 

electronic product, smoke and heat alarms have a limited life, and devices that 

don't work cannot protect you.

b. Follow safety rules and prevent hazardous situations:

w

Use smoking materials properly; never smoke in bed.

w

Keep matches and cigarette lighters away from children. 

w

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

flames or sparks.

w

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

electrical circuits.

w

Keep stoves, fireplaces, chimneys, and barbecue grills grease-free and make 

sure they are properly installed away from combustible materials.

w

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

materials.

w

Do not allow rubbish to accumulate.

w

Do not leave small children home alone.

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

especially small children. 

w

Draw and post 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.

w

Teach children what the smoke and heat 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.

w

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.

w

Hold fire drills at least every 6 months to make sure that everyone, even small 

children, know what to do to escape safely.

w

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

w

Provide emergency equipment such as fire extinguishers and teach your family 

to use this equipment properly.

d. Bedroom doors should be closed while sleeping if a smoke or heat 

alarm is installed in the bedroom.

They act as a barrier against heat and 

smoke.

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.
