WARNING: TEST YOUR SMOKE ALARM OPERATION
AFTER R.V. OR MOBILE HOME VEHICLE HAS BEEN IN
STORAGE, BEFORE EACH TRIP AND AT LEAST ONCE
A WEEK DURING USE.
8. 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.
9. Test the Smoke Alarm. See “Weekly Testing.”
2. LOCATIONS TO AVOID FOR ALARMS
In general, alarms should not be located:
• In the garage. Products of combustion are present when
you start your automobile.
• Less than 4” (10cm) from the peak of an “A” frame type
ceiling.
• 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 very humid areas or near a bathroom. Moisture or
steam can cause nuisance alarms.
• In insect-infested areas.
• Smoke alarms should not be installed within 3 ft (0.9m)
of the following: The door to a kitchen, the door to a
bathroom containing a tub or shower, forced air supply
ducts used for heating or cooling, ceiling paddle or whole
house ventilating fans, or other high air flow areas.
• Kitchens. Normal cooking may cause nuisance alarms. If
a kitchen alarm is desired, it should have an alarm silence
feature or be a photoelectric type.
• Near fluorescent lights, amateur radios, electrical
equipment or other devices known to transmit in the RF
band. Electronic “noise” may cause nuisance alarms.
• Near large metal surfaces and bundles of wire.

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 4).
6. Attach the mounting bracket to the ceiling or wall.
7. Install the battery (included). 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. (see
Figure 5)

4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once 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.)
SELF TESTING: Test by pushing the test button on the
cover. This unit’s red LED will flashes and the unit would
“chirp” three times, if the electronic circuitry, horn, and
battery are working. If no alarm sounds, the unit has
defective batteries or other failure. You can also test the
NOTE: After you install the battery, the power
indicator light may flash. (If the unit alarms, the
light will blink rapidly, and the horn will repeatedly
