1. RECOMMENDED LOCATIONS FOR ALARMS
• Locate the first alarm in the immediate area of the bedrooms but
not in the bedrooms. Try to protect the exit path as the bedrooms
are usually farthest from the exit. If more than one sleeping area
exists, locate additional alarms adjacent to each sleeping area.
• Locate additional alarms in the bedrooms if required.
• Locate additional alarms to protect any stairway as stairways act
like chimneys for smoke and heat.
• Locate at least one alarm on every floor level.
• Locate an alarm in every room where electrical appliances are
operated (i.e. portable heaters or humidifiers).
• Locate an alarm in every room where someone sleeps with the
door closed. The closed door may prevent the alarm from waking
the sleeper.
• Smoke, heat, and combustion products rise to the ceiling and
spread horizontally. Mounting the smoke alarm on the ceiling in the
center of the room places it closest to all points in the room. Ceiling
mounting is preferred in ordinary residential construction.
• When mounting an alarm on the ceiling, locate it at a minimum of
4" (10 cm) from the side wall (see Figure 1).
• When mounting the alarm on the wall, it is best to 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).
• Put smoke alarms at both ends of a bedroom hallway or large
room if the hallway or room is more than 30 feet (9.1 m) long.
• Install Smoke Alarms on sloped, peaked or cathedral ceilings at or
within 3ft (0.9m) of the highest point (measured horizontally). (see
Figure 2).
2. LOCATIONS TO AVOID FOR ALARMS
Alarms must not be located within 3 feet of the following:
• Supply and return registers used for forced air
heating and air conditioning.
• Ceiling fans and other high air flow areas.
• Bathrooms which contain a tub or shower.
In general, alarms should not be located:
• In the garage. Products of combustion are present
when you start your automobile.
• In an area where the temperature may fall below
40ºF or rise above 100ºF.
• In dusty areas. Dust particles may cause nuisance
alarms or failure to alarm.
• In a kitchen or cooking area where steam and
smoke from burning food or toast can cause nuisance
alarms.
• Near fluorescent lights. Electronic "noise" may cause
nuisance alarms.

3. INSTALLATION INSTRUCTIONS
1. Hold base firmly and twist the mounting bracket
counterclockwise to separate it from the base.
2. Hold the mounting bracket against the ceiling (or wall)
so the vertical mounting slot is aligned in the 12 o'clock
position and trace around the inside of the mounting
slots (vertical and horizontal mounting).
3. Put the unit where it won't get covered with dust when you
drill the mounting holes.
4. Using a 3/16" (5 mm) drill bit, drill a hole through the center
of the oval outlines you traced.
5. Insert the plastic screw anchors (in the plastic bag with
screws) into the holes. Tap the screw anchors gently with a
hammer, if necessary, until they are flush with the ceiling or
wall. (see Figure 3).
6. Attach the mounting bracket to the ceiling or wall.

7. Wiring the A.C. QUICK CONNECT harness (see Figure 4):
WIRES ON HARNESS CONNECTED TO
Brown Hot Side of A.C. Line
Blue Neutral Side of A.C. Line
8. Attach the mounting bracket to the ceiling or wall.
9 Install the DC9V battery. Open the battery drawer. Match
the terminals on the end of the battery with the terminals on
the unit. Match "+" to "+" and "-" to "-." Push the battery in until
it snaps in securely and cannot be shaken loose. If the battery
is not snapped in completely, the unit cannot receive battery
power.
10. Attach the Smoke Alarm to the mounting bracket. Line up
the guides on the alarm's base with the guides on the
mounting bracket. When guides are lined up, turn the base
clockwise (right) until it snaps into place.
11. Test the Smoke Alarm. See "Weekly Testing."
4. OPERATION AND TESTING
SILENCE FEATURE (HUSH CONTROL): The Silence
Feature has the capability of temporarily desensitizing the
smoke sensing circuitry in order to quiet your alarm while you
take care of a non-emergency event. This feature is to be
used only when a known alarm condition, such as smoke
from cooking, activates the alarm. When the unit alarm,
activate Silence Feature by pushing the button on the smoke
alarm cover, the alarm "chirp" twice, LED blink twice. If the
smoke is not too dense, the alarm will silence immediately.
The LED will blink twice every 10 seconds for
approximately 7 minutes to indicate that the alarm is in a
temporarily desensitized condition. The smoke alarm will
automatically reset after approximately 7 minutes, and will
sound again if particles of combustion are still present. The
Silence Feature can be used repeatedly until the air has been
cleared of the condition causing the alarm. Pushing the test
button on the alarm will end the Silence Feature period, the
alarm "chirp" once, LED blink once.
OPERATION: The smoke alarm is operating once the AC
power on or a fresh battery is installed and testing is complete.
When products of combustion are sensed, the unit sounds a
loud 85db pulsating alarm until the air is cleared.
FLASHING LED LIGHT: This smoke alarm is equipped with a
flashing red indicator light. The light will flash every 30 - 40
seconds to indicate that the smoke alarm is receiving power
SMOKE SENSING CHAMBER OPERATION: This alarm will
"chirp" if any of the components in the smoke sensing
chamber fail. This chirp will occur between the flashes of the
red LED indicator light. (If the chirp occurs at the same time
as the red LED flash, see Section 6 for low battery
information.)
WEEKLY TESTING: Test by pushing the test button on the
cover when unit in normal status. This will sound the alarm if
the electronic circuitry, horn, and AC power and battery are
working. If no alarm sounds, the unit has defective batteries
or other failure. You can also test the alarm by blowing smoke
into it. TEST THE ALARM WEEKLY TO ENSURE PROPER
OPERATION. Erratic or low sound coming from your alarm
may indicate a defective alarm, and it should be returned for
service.
5. NUISANCE ALARMS
Smoke alarms are designed to minimize nuisance alarms.
Cigarette smoke will not normally set off the alarm, unless the
smoke is blown directly into the alarm. If a smoke detector is
located in a bathroom or kitchen then nuisance alarms will
occur. Follow the "Locations to Avoid for Alarms" Section.
6. MAINTENANCE
BATTERY REPLACEMENT - To replace the battery, remove
the alarm from the mounting bracket by rotating the alarm
counterclockwise. The Smoke Alarm is powered by a DC 9V
battery. A fresh battery should last for one year under normal
operating conditions. When AC Power off, this alarm has a
low battery monitor circuit which will cause the alarm to
"chirp" approximately every 30 - 40 seconds for a minimum of
seven (7) days, accompanied by the red LED flash, when the
battery gets low. Replace the battery when this condition
occurs.
CLEANING YOUR ALARM - To clean your alarm, remove it
from the mounting bracket as outlined in the beginning of this
section. You can clean your alarm by using compressed air or
your vacuum cleaner hose to blow or suck air through the
openings around the perimeter of the alarm. The outside of
the alarm can be wiped with a damp cloth. After cleaning,
reinstall your alarm. Test your alarm by using the test button.
7. LIMITATIONS OF SMOKE ALARMS
Smoke alarms are devices that can provide early warning of
possible fires at a reasonable cost; however, alarms have
sensing limitations.
• A battery powered alarm must have a battery of the
specified type, in good condition and installed properly.
• Smoke alarms must be tested regularly to make sure the
batteries and the alarm circuits are operating correctly.
• Smoke alarms cannot provide an alarm if smoke does not
reach the alarm. Therefore, smoke alarms may not sense
fires starting in chimneys, walls, on roofs, on the other side of
a closed door or on a different floor.
• If the alarm is located outside the bedroom or on a different
floor, it may not wake up a sound sleeper.
• The use of alcohol or drugs may also impair one's ability to
hear the smoke alarm. For maximum protection, a smoke
alarm should be installed in each sleeping area on every level
of a home.
• Although smoke alarms can help save lives by providing an
early warning of a fire, they are not a substitute for an
insurance policy. Home owners and renters should have
adequate insurance to protect their lives and property.
