Lifetone HL Bedside Fire Alarm Alert & Clock Combo (LIFETONEHL)

The Lifetone HLAC151 actively listens for the sound of your T3 smoke alarm; once it hears the smoke alarm, it will provide several reliable notifications:

Audible notification via 520 Hz square-wave alarm – this low frequency audible sound has been proven to be the most effective at waking people during a fire emergency (most smoke alarms emit a high frequency sound)

Audible instructions in a low, baritone voice ‘FIRE, GET OUT!’ are repeated during the pauses between the audible tone

Visual notification – the word ‘FIRE’ is displayed in large text against the bright flashing orange backlight

Tactile notification – power bedshaker vibrates, especially important for night-time safety
