Lifetone Technology offers the Lifetone HL Bedside Fire Alarm and Clock. The Lifetone HL uses the alarms proven most effective for waking people by the US Fire Administration. People who urgently need the life-saving Lifetone HL are children, heavy sleepers, seniors, and people with hearing loss. Lifetone Technology’s Mission is to continue to develop and market proprietary, code-compliant products which provide improved alarming and alerting capability in response to emergencies as compared to existing solutions.
The Lifetone HL uses patented monitoring technology—perfected over 10 years of development—to actively listen for the sound of your smoke alarm (and ignore all other sounds at the same frequency, about 3100 Hz). When it hears your smoke alarm it immediately initiates three different signals to wake you up.
The special 520 Hz square-wave alarm sound has been proven in controlled scientific testing as the most effective at waking people up in a fire emergency. The Lifetone HL pumps out the alarm signal at 90 dBA.
The company is headquartered in Oklahoma City, Oklahoma, with administrative offices in Oakbrook Terrace in suburban Chicago.
