Standby Condition: The red LED will flash every 45
seconds to indicate that the smoke
alarm is operating properly.
Alarm Condition: When the alarm senses products of
combustion and goes into alarm, the
red LED will flash rapidly (once every
second). The rapid flashing LED
and temporal alarm will continue
until the air is cleared.
Hush Condition: The red LED will flash every 10 seconds
as long as the alarm is in Hush mode.
Low Battery Condition: The red LED flash will be accompanied
by an audible chirp. Replace the battery
when this condition occurs.
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 sec-
tion 6 for low battery information).
TESTING: Test by pushing the test button on the cover and hold
it down for a minimum of 5 seconds. This will sound the alarm
if the electronic circuitry and horn and battery are working. If no
alarm sounds, the unit has defective batteries or other failure. DO
NOT use an open flame to test your alarm, you could damage the
alarm or ignite combustible materials and start a structure fire.
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 (see section
12).
NOTE: WEEKLY TESTING IS REQUIRED.
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. Combustion particles from
cooking may set off the alarm if the alarm is located close to the
cooking area. Large quantities of combustible particles are gener-
ated from spills or when broiling. Using the fan on a range hood
which vents to the outside (non-recirculating type) will also help
remove these combustible products from the kitchen.
If the alarm does sound, check for fires first. If a fire is discovered,
