Heat Alarm User’s Guide

AC Wire-in Single and/or Multiple Station (up to 24 Devices) Heat Alarm
with 9 Volt Battery Back Up, 135ºF fixed temperature.

Thank you for purchasing this heat alarm. It is an important part of your family’s
home safety plan. You can trust this product to provide the highest quality safe­ty protection. We know you expect nothing less when the lives of your family
are at stake. Kidde alarms and accessories CAN ONLY BE interconnected with
other Kidde alarms and accessories as well as specified brands and models of
interconnect compatible alarms. Connection of Kidde products to a non-speci­fied manufacturer’s interconnect system, or connection with non-specified
equipment from another manufacturer into an existing Kidde system could result
in nuisance alarming, failure to alarm, or damage to one or all of the devices in
the interconnect system. Refer to the User’s Guide supplied with each Kidde
product for interconnect compatible models, brands, and devices. Refer to the
wiring instructions in section 3 for NFPA initiating device limits

response time as sprinkler devices spaced at 10-Ft intervals (100 Sq/Ft) on a
smooth ceiling approximately 15 feet high. Higher ceilings may adversely affect
response time and earlier response time may be obtained by reducing the spac­ing between alarms.

Note B: Maximum distance is from any wall or ceiling projection extending
down more than 12 inches.

2. RECOMMENDED LOCATION OF ALARMS

• The most favorable mounting location
for a heat alarm is on the ceiling in the
center of the room. At this location the
alarm is closest to all areas of the room
(see figure 3).

EXCEPTION: When the mounting surface
might become considerably warmer or
cooler than the room, such as a poorly
insulated ceiling, below an unfinished attic,
or an exterior wall. In these cases the alarm
should be mounted on an inside wall.

• If the alarm cannot be located in the
center of the room, an off-center location
can be used on the ceiling. When off cen-

FIGURE 1

ter mounting an alarm on the ceiling,
locate it at a minimum of 4" (10 cm) from
the side wall (see figure 3).

• If a ceiling mounting location is not fea­sible the next logical location for mounting
heat alarms is on the side wall. When
mounting the alarm on the wall, use an
inside wall with the top edge of the alarm
at a minimum of 4" (10 cm) and a maxi­mum of 12" (30.5 cm) below the ceiling
(see figure 1).

• Install Heat Alarms on sloped, peaked or cathedral ceilings at or within 3 ft
(0.9m) of the highest point (measured horizontally). NFPA 72 states: “Smoke
alarms in rooms with ceiling slopes greater than 1 ft in 8 ft (.3m in 2.4m) hori-

FIGURE 2

zontally shall be located on the high side of the room.” NFPA 72 states: “A row

of alarms shall be spaced and located
within 3 ft (0.9m) of the peak of the
ceiling measured horizontally” (see
figure 3).

• In rooms with open joists or
beams, all ceiling mounted alarms
shall be located on the bottom of
such beams (see figure 2).

• 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 the solid joist (See
figure 2).

MOBILE HOME INSTALLATION

Modern mobile homes have been

FIGURE 3

designed and built to be energy effi­cient. Install heat alarms as recom­mended above (refer to RECOMMENDED LOCATIONS and FIGURE 1).

In older mobile homes that are not well insulated compared to present stan­dards, extreme heat or cold can be transferred from the outside to the inside
through poorly insulated walls and roof. This may create a thermal barrier
which can prevent the heat from reaching an alarm mounted on the ceiling. In
such units, install the heat alarm on an inside wall with the top edge of the
alarm at a minimum of 4” (10 cm) and a maximum of 12” (30.5 cm) below the
ceiling (see figure 1).

If you are not sure about the insulation in your mobile home, or if you notice
that the outer walls and ceiling are either hot or cold, install the alarm on an
inside wall.

WARNING: TEST YOUR HEAT ALARM OPERATION AFTER RV OR MOBILE
HOME VEHICLE HAS BEEN IN STORAGE, BEFORE EACH TRIP AND AT
LEAST ONCE A WEEK DURING USE.

3. LOCATIONS TO AVOID

• In front of forced air supply ducts used for heating and air conditioning, near

ceiling fans, or other high air flow areas.

• In an area where the temperature may fall below -20ºF or rise above 100ºF.

• Near fluorescent lights – electronic "noise" may cause nuisance alarms.

• Heat alarms are not to be used with detector guards unless the combination

(alarm and guard) have been evaluated and found suitable for that purpose.

4. INSTALLATION INSTRUCTIONS

WIRING REQUIREMENTS

• This smoke alarm should be installed on a U.L. listed or recognized junction

box. All connections should be made by a qualified electrician and all wiring
used shall be in accordance with articles 210 and 300.3(B) of the U.S. National
Electrical Code ANSI/NFPA 70, NFPA 72 and/or any other codes having jurisdic­tion in your area. The multiple station interconnect wiring to the alarms must
be run in the same raceway or cable as the AC power wiring. In addition, the
resistance of the interconnect wiring shall be a maximum of 10 ohms.

• The appropriate power source is 120 Volt AC Single Phase supplied from a

non-switchable circuit which is not protected by a ground fault interrupter.

• WARNING:This alarm cannot be operated from power derived from a square

wave or modified square wave inverter. These type of inverters are sometimes
used to supply power to the structure in off grid installations, such as solar or
wind derived power sources. These power sources produce high peak voltages
that will damage the alarm.

WIRING INSTRUCTIONS FOR AC QUICK CONNECT HARNESS

CAUTION! TURN OFF THE MAIN POWER TO THE CIRCUIT BEFORE WIRING
THE ALARM.

• For alarms that are used as single station, DO NOT CONNECT THE RED WIRE

TO ANYTHING. Leave the red wire insulating cap in place to make certain that
the red wire cannot contact any metal parts or the electrical box.

• When alarms are interconnected, all interconnected units must be powered

from a single circuit.

• A maximum of 24 Kidde/Lifesaver devices may be interconnected in a multiple

station arrangement. The interconnect system should not exceed the NFPA
interconnect limit of 12 smoke alarms and/or 18 alarms total (smoke, heat,
carbon monoxide, etc.). With 18 alarms interconnected, it is still possible to
interconnect up to a total of 6 remote signaling devices and/or relay modules.
