120V AC
Heat Alarm
9V
with
Battery
Back-up
WARNING! Heat alarms are not life safety devices and are not designed to
detect smoke or fire. Heat alarms detect temperatures of 135°
and are intended to be used as supplements to smoke alarms by providing
early warning. See the IMPORTANT SAFETY INFORMATION section of this
manual.
Printed information describing proper installation, operation, testing,
maintenance, evacuation planning, and repair service is provided with
this equipment in this manual.
• This heat alarm is powered by 120V AC and a 9-volt battery
back-up source. AC/DC heat alarms offer added protection in the
event of a power failure or a drained battery.
• Unique power connector prevents interconnection with
incompatible heat alarms, smoke alarms, or security systems.
• This heat alarm is interconnectable to a maximum of 12 Firex
devices. It is compatible with Firex smoke alarm models AD,
ADC, and FADC. It can be interconnected with Firex heat alarm
model ADH (6 maximum).
• Optional tamper-resist feature.
• Unique "battery missing" lockout – heat alarm will not attach to
the mounting bracket if a battery is not in the battery pocket.
• Improperly connected or weak battery signal – heat alarm will
sound a short beep once a minute if the battery is weak or
improperly connected.
• Green LED indicates that the heat alarm is receiving AC power,
working under normal operation, or in alarm.
• Loud alarm horn—85 decibels at 10 feet—sounds to alert you
to an emergency.
• Test button checks heat alarm operation.

NOTE A: Maximum alarm coverage has been determined by UL to provide detection
time equal to sprinkler devices spaced at 10-ft intervals (100 square foot area) on a
smooth ceiling 15 ft 9 in. high. Higher ceilings can adversely affect detection time. In
some instances, earlier detection may be obtained by reducing the distance between
detectors. See the latest edition of the NFPA 72E, Automatic Fire Detectors.
NOTE B: Maximum distance is measured from any wall partition or ceiling projection
extending down more than 12 inches.
IMPORTANT SAFETY INFORMATION
!
• This heat alarm requires constant 120-volt, AC power AND
a working 9-volt battery to operate properly. This heat alarm
WILL NOT work if AC power is not connected, has failed, or
has been interrupted for any reason AND if the battery is
removed, drained or improperly connected. DO NOT use any
other kind of battery except as specified in this manual. DO
NOT connect this heat alarm to any smoke alarm, heat alarm,
or auxiliary device, except those listed in this manual.
• The Push-to-Test button accurately tests all heat alarm
functions. For temperatures that are below -10°F use a hand
held hair dryer and blow hot air into heat alarm to test. DO
NOT use any other test method. Test heat alarm weekly to
ensure proper operation.
• This heat alarm should be installed only by a licensed, qual-
ified electrician. Observe and follow all local and national elec-
trical and building codes for installation.
