CAUTION: BEFORE USING THE ALARM HUSH FEATURE,
IDENTIFY THE SOURCE OF THE SMOKE AND BE CERTAIN
A SAFE CONDITION EXISTS.
LED INDICATORS: This smoke alarm is equipped with red and green
LED indicators. The red LED is located under the test button and has
two modes of operation.
Standby Condition: The red LED will flash every 30-40
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 (one flash per second).
The rapid flashing LED and pulsating 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.
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).
WHEN UNITS ARE INTERCONNECTED, only the red LED of the alarm
which senses the smoke or is being tested (the originating unit) will
flash rapidly. All other units in the interconnect system will sound an
alarm but their red LED’s will NOT flash rapidly.
The green LED will be steady on to indicate the presence of AC power.
TESTING: Test by pushing the test button on the cover and holding it
down for a minimum of 5 seconds. This will sound the alarm if the
electronic circuitry, horn, and battery are working. In an intercon-
nected installation all interconnected alarms should sound when the
test button on any one of the interconnected alarm is pressed. If no
alarm sounds, check the fuse or circuit breaker supplying power to
the alarm circuit. Verify the green LED is on. If the alarm still does
not sound, 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.
