*When any Heat Alarm in an interconnected series triggers an alarm, its green
LED will flash rapidly. The green LEDs will not flash on any remaining alarms in
the series. This feature helps responders identify which unit(s) triggered the alarm.

RESPONDING TO AN ALARM
During an alarm, you will hear a loud, repeating horn pattern:
3 beeps, pause, 3 beeps, pause.
3 beeps, pause, 3 beeps, pause.
• If the unit alarms and you are not testing the unit, it is warning you
of a potentially dangerous situation that requires your immediate
attention. NEVER ignore any alarm. Ignoring the alarm may result
in injury or death.

in injury or death.
• Never disconnect the AC power to quiet an unwanted alarm.
Disconnecting the power disables the alarm so it cannot sense
heat. This will remove your protection.

• If the unit alarms and you are not absolutely certain of the source
of the heat, get everyone out of the house immediately.
• ELECTRICAL SHOCK HAZARD: Attempting to disconnect the power
connector from the unit when the power is on may result in electrical

RECOMMENDED LOCATIONS FOR HEAT ALARMS
In Single-Family Residences.
For minimum coverage, BRK Brands, Inc. recommends you install Heat
Alarms in any area not suitable for smoke alarms such as garages, kitchens,
utility/laundry rooms, furnace rooms and crawl spaces. Install where tempera-
tures normally remain between –10º F and 100º F (–23º C and 38º C).
For National Fire Protection Association (NFPA) information, see “Agency
Placement Recommendations for Heat Alarms and Smoke Alarms.”

RECOMMENDED PLACEMENT
Heat Alarms Recommended in New Home Construction
• The recommended location for a Heat Alarm is at the center of the
ceiling. At this location, the Heat Alarm is closest to all areas of the
room.

• If it is not practical to install the Heat Alarm in the center of the room,
use an off-center location not less than 4 inches (102 mm) from the
sidewall.
sidewall.
• If it is not practical to install the Heat Alarm on the ceiling, the next
logical location is on a sidewall. A Heat Alarm mounted on a sidewall
should have the top of the unit between 4 and 12 inches (102 mm and
305 mm) from the ceiling.

• The smooth ceiling distance between Heat Alarms shall not exceed
spacings as determined by UL fire tests. This Heat Alarm has a 50 foot
(15 meter) spacing.
(15 meter) spacing.
• Reduced spacing may be required due to factors such as exposed
joists, drafts, ceiling heights greater than 10 feet (3 meters), and other
structural characteristics that may affect Heat Alarm operation. Walls,
partitions, doorways, and joists interrupt the normal flow of heat
creating new areas to be protected.

NFPA Standard 72 Appendix A-2-5.2.2.2 part c-d
(c) The Spacing of Detectors: Where a room is too large for protection
by a single detector, several detectors should be used. It is important
that they be properly located so all parts of the room are covered.
(d) Where the Distance Between Detectors Should Be Further Reduced:
The distance between detectors is based on data obtained from the
spread of heat across a smooth ceiling. Where the ceiling is not smooth,
the placement of the detector should be tailored to the situation.
by a single detector, several detectors should be used. It is important

(d) Where the Distance Between Detectors Should Be Further Reduced:
The distance between detectors is based on data obtained from the
spread of heat across a smooth ceiling. Where the ceiling is not smooth,
the placement of the detector should be tailored to the situation.
For instance, with open wood joists, heat travels freely down the joist
channels so that the maximum distance between detectors [50 ft (15 m)]
may be permitted to be used. However, heat has trouble spreading
across the joists, so the distance in this direction should be 1/2 the
distance allowed between detectors, as shown in the illustration above
(“Heat Alarms Recommended in New Home Construction”) and the
distance to the wall is reduced to 12-1/2 ft. (3.8 m). Since 1/2 x 50 ft.
(15 m) is 25 ft. (7.6 m), the distance between detectors across open
wood joists should not exceed 25 ft. (7.6 m), as shown in “Heat Alarms
Recommended in New Home Construction,” and the distance to the wall
is reduced [1/2 x 25 ft. (7.6 m)] to 12.5 ft. (3.8 m). Paragraph 2-5.2.2.4
requires that detectors be mounted on the bottom of the joists and not
up in joist channels.

IF YOU SUSPECT A PROBLEM
Heat Alarms may not operate properly because of a build-up of dirt, dust or
grease on the Heat Alarm cover, or installation in an improper location. Clean
the Heat Alarm as described in “Regular Maintenance,” then test the Heat
Alarm again. If it fails to test properly when you use the test button, or if the
problem persists, replace the Heat Alarm immediately.
