Lifetone HL

Lifetone HL

Lifetone HL Bedside Fire Alarm and Clock works better because it works differently.

Operating in tandem with a conventional T3 smoke alarm, the Lifetone HL patented hearing sensor constantly monitors for alarm signals. When it hears a smoke alarm from any room in the house, it activates a 520 Hz square-wave alarm.

• Offers protection at the bedside, where it is most needed.
• Requires no installation.
• Includes 7-day battery back-up.
• Provides dual functionality as a standard alarm clock.
• Includes an intermittent bed shaker to complement the audio alarm.
