Testing
Test your smoke detector weekly by pressing the test button
(the clear button on the front of the sensor) for 4 seconds. The
siren will sound (3 beeps, pause, 3 beeps) and the light will
flash continuously and rapidly.
If the smoke alarm beeps three times with the yellow LED
flashing three times in 43 seconds, it indicates the smoke
alarm is not working properly - it must be repaired or replaced.
This is the only way to make sure that the smoke alarm unit is
working properly. If the unit fails to test properly, have it
repaired or replaced immediately.
Caution: Continuous exposure to the high sound level of this
alarm over an extended period of time may cause hearing loss.
WARNING: Never use an open flame of any kind to test your
alarm. You may damage the alarm as well as your home. The
built-in test switch accurately tests all functions as required by
Underwriters’ Laboratories.
WARNING: When you are not testing the unit and the alarm
siren sounds, the alarm is a warning of a possible serious
situation, which requires your immediate attention.
Silence Feature
Press the “test/silence” button (the clear button on the front of
the detector) to temporarily quite an alarm for up to 10 minutes.
If smoke is still present around the smoke alarm after 10
minutes of silence, the unit will re-alarm.
Operating Modes
The LED light on the front of the sensor indicates the operating
mode of the smoke alarm:
Red LED blinks 3 times rapidly: The detector has sensed a
potentially dangerous level of smoke. The buzzer and alarm
siren will also sound. Please follow the "in case of fire"
instructions.
Red LED blinks about once per minute: your detector is
functioning normally.
Red LED blinks AND chirps once per minute: the Smoke
Detector battery is low battery. This low battery warning signal
should last for up to 30 days, but you should install a new
CR123A battery immediately.
Yellow LED blinks three times per minute: this indicates the
unit has malfunctioned and needs to be replaced.
Yellow LED blinks three times and chirps 3 times every 30
seconds: this indicates that the unit is no longer operating
within its intended sensitivity and must be replaced.
Yellow LED stays on solid and alarm soudns: the smoke
alarm is not mounted correctly in its bracket.
Maintenance tips
To keep your alarm in good working order open the cover and
vacuum the dust off the alarm’s sensing chamber at least once
a month.
Remove the battery before cleaning.
Use soft brush attachment on your vacuum to carefully
remove any dust, especially on the openings of the sensing
chamber. Never use water or cleaners.
Replace the battery after cleaning. Test the smoke alarm to
make sure battery is working correctly.
WARNING! LIMITATIONS OF SMOKE ALARMS
Wireless smoke alarms are very reliable, but may not work
under all conditions. No fire alarm provides total protection of
life or property. Smoke alarms are not a substitute for life
insurance.
Smoke alarms require a source of power to work. This
smoke alarm will not operate and the alarm will not sound if
batteries are dead or not installed properly.
Smoke alarms may not be heard. A sound sleeper or
someone who has taken drugs or alcohol may not awaken if
the alarm is installed outside a bedroom. Closed or partially
closed doors and distance can block sound. This alarm is not
designed for the hearing impaired.
Smoke alarms may not always activate and provide
warning early enough. Smoke alarms only activate when
enough smoke reaches the alarm. If a fire starts in a chimney,
wall, roof, on the other side of closed doors, or on a different
level of the property enough smoke may not reach the alarm
for it to alarm.
Smoke alarms are a significant help in reducing loss,
injury and even death. However, no matter how good a
detection device is, nothing works perfectly under every
circumstance and we must warn you that you cannot
expect a smoke alarm to ensure that you will never suffer
any damage or injury.
Fire prevention and escape
The purpose of an early warning smoke alarm is to detect the
presence of fire in its early stages and sound an alarm giving
the occupants time to exit the premises safely.
Avoid fire hazards
• Do not smoke in bed.
• Do not leave children home alone.
• Never clean with flammable liquids such as gasoline.
• Properly store materials. Use general good housekeeping
techniques to keep your home neat and tidy. A cluttered
basement, attic, or other storage area is an open invitation to
fire.
