3. Operation
Testing
NOTE: WEEKLY TESTING IS REQUIRED
CAUTION: Due to the loudness (85 decibels) of the alarm, always stand an
arms length away from the unit when testing.
The smoke alarm is operating once a fresh battery is installed and testing
is complete. When the smoke alarm photoelectric sensor chamber senses
products of combustion, the horn will sound a loud (85 db) alarm until
the sensing chamber is cleared of smoke particles.
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 all the electronics,
circuitry, horn and battery are working. If the alarm does not sound and
you have already replaced the battery, the alarm must be replaced. DO
NOT use an open flame to test your alarm, you could damage the alarm
or ignite combustible materials and start a 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 Warranty section).
This smoke alarm is equipped with a flashing red indicator light. The red
LED is located under the test button and will flash every 40 seconds to
indicate that the smoke alarm is receiving power.
When products of combustion are sensed, the unit sounds a loud 85db
pulsating alarm, and the red LED rapidly flashes every 2 seconds, until the
air is cleared.
Alarms failing an alarm test, or not operating normally, must be replaced
with a new alarm. Similarly, alarms more than 10 years old must be replaced.
