A Lifetone Bedside Fire Alarm and Clock in your home
provides your family with affordable fire protection and alerting in the event
of a fire. The Lifetone alarm unit has audio and vibration alerting to notify
deaf and hearing individuals. Lifetone is not a smoke detector. This product
works with smoke alarms that emit a T3 alarm pattern (three beeps followed by a
pause). It will not work with alarms that emit a continuous tone pattern with
How does Lifetone work?
Lifetone HL uses
patented monitoring technology to actively listen for the sound of your smoke
alarm, and ignore all other sounds at the same frequency, about 3100Hz. When it
detects your smoke alarm, it immediately initiates three different signals to
wake you up:
Special low pitched, 520Hz square-wave T3 alarm sound proven
in controlled scientific testing as the most effective at waking people in a
fire emergency. The Lifetone HL has a 85dB alarm signal - that's like having
someone start a lawn mower next to your bed.
The Lifetone HL has a baritone voice that says "Fire!
Get out!" in English or Spanish.
The Lifetone HL has a visual signal on the backlit display
that flashes the word "FIRE." In a darkened room, the flashing
display is another form of sensory stimulation to "break through" the
fogginess of sleep.
The Lifetone HL comes with a small bed shaker that will
vibrate strongly when the alarm is triggered. Connect it for vibration
