WHAT YOU SHOULD KNOW ABOUT HEAT ALARMS
Heat alarms are not life safety devices and are not designed to detect
smoke or fire. They are intended to detect temperatures of 135oF to
provide an additional source of information that is supplemental to
smoke alarms to increase the probability that an early warning will
be provided to increase chances of life and property safety.
FEATURES
•
This heat alarm is powered by 120 VAC and a 9 Volt battery backup source. AC/
DC heat alarms offer added protection in the event of a power failure or a drained
battery.
•
This heat alarm can be interconnected with as many as 12 other USI alarms
(Models USI-1103, USI-1203, USI-1204, USI-1208, USI-1209, USI-1213, USI-3204,
USI-5204 and 6 other units which may be a combination of Carbon Monoxide
Alarms such as USI-7385, USI-7390, USI-7485, USI-7490 and USI-7795, USI-
2430 Heat Alarms or USI-960 Relay Modules, for a total of not more than 18
interconnected devices.
•
•
•
This heat alarm will not attach to the mounting ring if a battery is not in the battery
chamber.
This heat alarm will sound a short beep about once a minute if the battery is weak
or improperly connected.
The green LED indicates that the heat alarm is receiving AC power and is working
under normal operation.
•
•
A loud 85 decibels at 10 feet alarm horn will sound to alert you of an emergency.

• This heat alarm can only sound its alarm when it detects temperatures of 135o F or
greater. Heat alarms do not sense smoke, fire or gas. In some fires, hazardous
levels of toxic chemicals and smoke can build up before a heat alarm will operate.
Temperatures may not reach 135o F to activate the heat alarm quickly enough to
ensure safe escape.
• Heat alarms have limitations. This heat alarm is not foolproof and is not warranted
to protect lives or property. Heat alarms are not a substitute for insurance.
Homeowners and renters should insure their lives and property. In addition, it is
possible for the heat alarm to fail at any time.
HEAT ALARM PLACEMENT
Heat alarms give an audible warning when the temperature at the alarm reaches 135o
F. Heat alarms are ideal for kitchens, garages, basements, boiler rooms, attics and
other areas where there are normally high levels of fumes, smoke or dust which are
also areas where smoke alarms should not be installed due to risk of false nuisance
alarms.

NATIONAL FIRE PROTECTION ASSOCIATION REQUIRED PROTECTION
For your information, the National Fire Protection Association's Standard 72, reads as follows:
“11.5.1 One- and Two-Family Dwelling Units. 11.5.1.1 Smoke Detection. Where required
by applicable laws, codes, or standards for the specified occupancy, approved single-
and multiple-station smoke alarms shall be installed as follows: (1) In all sleeping
rooms. Exception: Smoke alarms shall not be required in sleeping rooms in existing
one- and two-family dwelling units. (2) Outside of each separate sleeping area, in
immediate vicinity of the sleeping rooms. (3) On each level of the dwelling unit,
including basements. Exception: In existing one- and two-family dwelling units, approved
smoke alarms powered by batteries are permitted.
“A.11.8.3Are 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.”
The equipment should be installed using wiring methods in accordance with the National Fire
ProtectionAssociation’s Standard 72, Chapter 11. (National Fire ProtectionAssociation, Batterymarch
Park, Quincy, MA 02269).

HEAT ALARM LOCATIONS
Install a heat alarm as close to the center of the ceiling as possible. If the center is not
practical, mount the heat alarm no closer than 4 inches from a wall or corner.
If the ceiling is not practical or the mounting surface becomes considerably warmer
or cooler than the room, such as a poorly insulated ceiling, below an unfinished attic
or an exterior wall (if local codes allow), install the heat alarm on inside walls with the
top of the alarm between 4 and 12 inches from the ceiling/wall intersections.
Install heat alarms on peaked cathedral or gabled ceilings 3 feet from the highest point
(measured horizontally).
In rooms with open joists or beams, all ceiling mounted heat alarms should be located
on the bottom of such joists or beams and not up in joist channels.
Heat alarms installed on an open-joisted ceiling shall have their smooth ceiling spacing
reduced to no more than half of the listed spacing when measured at right angles to
a solid joist.
DO NOT INSTALL HEATALARMS
•
In areas with high humidity, like bathrooms/shower rooms or areas near
dishwashers or washing machines. Install at least 10 feet (3m) away from these
areas if possible.
•
Near air returns or heating and cooling supply vents, fans, decorative objects,
window molding, etc. that may prevent heat from entering the unit thus interrupting
its alarms.
•
•
In an area where temperature may fall below -10oF (-23oC) or rise above 100oF
(38oC).
Near fluorescent lights. Electrical "noise" and flickering may affect the alarm's
operation.
MOBILE HOME INSTALLATION
For mobile homes built after 1978, install heat alarms as directed above. For mobile
homes built before 1978, install heat alarms on inside wall between 4 and 12 inches
from the ceiling. Older mobile homes have little or no insulation in the ceiling which
may affect the heat alarm's ability to detect heat properly. This is especially important
if the ceiling is unusually hot or cold.

INSTALLATION
Installation of this unit must conform to the electrical codes in your area;
Article 760 of the National Electrical Code, NFPA 72, 101; SBC (SBCCI);
UBC (ICBO); NBC (BOCA): OTFDC (CABO), and any other local or building
codes that may apply. Wiring and installation must be performed by a
licensed electrician. Failure to follow these guidelines may result in injury
or property damage.
This unit must be powered by a 24-hour, 120V AC 60Hz circuit. Be sure the
circuit cannot be turned off by a switch, dimmer or ground fault circuit interrupter.
Failure to connect this unit to a 24-hour circuit may prevent it from providing
constant protection.
iMPORTANT: Do not subject this alarm to megger, high voltage or high-
pot tests. Remove the heat alarm(s) before high-potting tests occur on the
circuit or system. (Ref. Section 550-17 National Electric Code, 2002 Edition).
ELECTRICAL SHOCK HAZARD
Turn off power to the area where you will install this unit at the circuit breaker or
fuse box before beginning installation. Failure to turn off the power before
installation may result in serious electrical shock, injury or death.
TAMPER LOCKING PIN: To make your heat alarm somewhat tamper resistant, a
locking pin has been provided. Using this pin will deter children and others from
removing the alarm from the mounting ring. To use the pin, insert it into the hole in the
side of the alarm after it has been installed on the mounting ring. Note that the tamper
pin will have to be removed in order to change the battery, which can be done easily
with a pair of long nose pliers. Using the long nose pliers, pull the pin out of the hole.
It is now possible to remove the heat alarm from the mounting ring.
1. Turn the heat alarm counterclockwise to remove it from the mounting ring. NOTE:
The heat alarm is sealed and the cover is not removable. Your heat alarm is also
equipped with a safety device which prevents mounting unless a battery is installed.
If your heat alarm will not lock onto the mounting ring, check to make sure a
battery is installed.
2. Wiring Instructions:
a. The appropriate power supply is 120 Volt single phase power supplied from a
non-switchable circuit NOT protected by a ground fault circuit interrupter.
b. Turn off main power to the circuit before wiring the heat alarm.
c. There are three pigtail leads (black, white and yellow) coming from the AC
QUICK CONNECTOR. The proper wire connection is as follows:
WIRES FROM QUICK CONNECTOR
CONNECT TO
"HOT" side of AC line
"NEUTRAL" side of AC line
Interconnect wires of other units
BLACK
WHITE
YELLOW
For units that are used as single heat alarms, do not connect the yellow wire to
anything. Insulate this wire (tape it) in place to make certain the yellow wire
cannot contact any metal parts.
Interconnected units can provide earlier warning of fire than stand-alone units,
especially if a fire starts in a remote area of the dwelling. This heat alarm may be
interconnected with as many as 12 other USI model smoke alarms such as USI-1103,
USI-1203, USI-1204, USI-1208, USI-1209, USI-1213, USI-3204, USI-5204 and 6 other
units which may be a combination of Carbon Monoxide Alarms such as USI-7385,
USI-7390, USI-7485, USI-7490, USI-7795, Heat Alarms/USI-2430 or Relay Modules/
USI-960 for a total of not more than 18 interconnected devices.
- 6 -
Interconnected CO alarms will only respond if a CO alarm / event initiates the
alarm. All other alarms remain silent.
Interconnected smoke alarms, heat alarms and relay modules will only respond if
a smoke alarm / event or heat alarm / event initiates the alarm. All CO alarms
remain silent.
NOTE: Relay Modules/USI-960 will not respond if a CO alarm / event initiates the
alarm.
NOTE: Units without battery backup will not respond during an AC power failure.
The yellow wire is used only for multiple station operation with USI Models only.
Connecting this yellow wire to any other circuits may result in damage. When heat
alarms are interconnected, all units must be powered from a single AC branch
circuit. If local codes do not permit be sure the neutral wire is common to both
phases. The maximum wire run distance between the first and last heat alarm in an
interconnected system is 1,000 feet. NOTE: Use standard household wire (18 gauge
or larger, rated at least 300V, as required by local codes) available at all electrical
supply/hardware stores.
The wiring to be used shall be in accordance with the provisions of Articles 210
and 300.3(B) of the National Electrical Code, ANSI/NFPA 70. In addition, the
resistance of the interconnecting wiring shall be a maximum of 10 Ohms.
Early warning fire detection is best achieved by the installation of fire detection
equipment in all rooms and areas of the household as follows: A smoke alarm
installed in each separate sleeping area (in the vicinity of, but outside of, the
bedrooms) and heat or smoke alarms in living rooms, dining rooms, kitchens,
hallways, attics, furnace rooms, closets, utility storage rooms, basements and
attached garages. Test the heat or smoke alarm weekly to assure proper operation.
3. Attach the mounting ring to the electrical junction box.

OPERATION, TESTING & MAINTENANCE
OPERATION: The heat alarm is operating once the power is connected and turned
on (the battery must also be installed). When air temperature above 135oF is sensed,
the unit sounds a loud alarm which continues until the air is cleared.
This alarm incorporates the internationally recognized horn signal for evacuation. During
alarm mode, the horn produces three short beeps followed by a two second pause
and then repeats. This pattern is somewhat different than the previous alarm sound,
which continually beeped.
STANDBY CONDITION: The red LED flashes once every 40-60 seconds to indicate
the unit is properly functioning.
LOCAL ALARM CONDITION: The red LED flashes rapidly and the unit emits a loud,
pulsating alarm sound.
REMOTE ALARM CONDITION: The red LED is off and the unit emits a loud, pulsating
alarm.
GREEN LED: The green LED is on whenever AC power is turned on.
TESTING: Test by pushing the test button on the heat alarm cover until the alarm
sounds, then release. The alarm sounds if all electronic circuitry, horn and battery are
working. If no alarm sounds, the unit may have a defective battery or other failure.
NEVER use an open flame of any kind to test this unit. You might accidentally
damage or set fire to the unit or to your home. The built-in test switch accurately
tests the unit's operation as required by Underwriters Laboratories Inc. (UL).
BACKUP BATTERY REPLACEMENT
Disconnect AC power before changing battery. Shock hazard exists if AC power
is miswired.
The heat alarm uses a 9 Volt battery. The battery should last for at least one year
under normal operating conditions. The heat alarm has a low battery indicator, an
audible "beep." It will operate at 30-40 second intervals for a minimum of 7 days.
When this indication occurs, replace the battery with an Alkaline type (Eveready
Energizer #522, Duracell #MN1604), Carbon-Zinc type (Gold Peak #1604P, Eveready
#216), or Lithium type (ULTRALIFE U9VL-J).
Push and lift the battery door latch and remove the battery from the battery door.
While observing polarity, push the replacement battery into the battery door until it is
held securely in place. Carefully close and latch the battery door.
REPAIRS AND SERVICES
If the heat alarm is defective in any way, do not tamper with the unit. Return the unit
for servicing. (See warranty for instructions or in-warranty returns.) There will be a
service charge for repairing out of warranty units.

DEVELOP AND PRACTICE A PLAN OF ESCAPE
BASICS OF ESCAPE PLAN
o Make a floor plan indicating all doors and windows and at least two escape routes
from each room. Second story windows may need a rope or chain ladder.
o Have a family meeting and discuss your escape plan, showing everyone what to
do in case of fire.
o Determine a place outside your home where all of you can meet if a fire occurs.
o Familiarize everyone with the sound of the heat alarm and train them to leave your home
when they hear the sound.
o Identify children's bedrooms with red stickers placed in the upper left corner of the
windows. They are available from your local fire department.
o Practice a fire drill at least every six months. Practice allows you to test your plan
before an emergency. You may not be able to reach your children. It is important
they know what to do!
WHAT TO DO WHEN THEALARM SOUNDS
o Leave immediately by your plan of escape. Every second counts, so don't waste
time getting dressed or picking up valuables.
o In leaving, don't open any inside door without first feeling its surface. If hot, or if
you see smoke seeping through cracks, don't open that door! Instead, use
your alternate exit. If inside door is cool, place your shoulder against it, open it
slightly and be ready to slam it shut if heat and smoke rush in.
o Stay close to the floor if air is smoky. Breathe shallowly through a cloth, wet if
possible.
o Once outside, go to your selected meeting place and make sure everyone is there.
o Call the fire department from your neighbor's home – not from yours!
o Don't return to your home until fire officials say that it is all right to do so.
