Lifetone HLAC 151 Bedside Fire Alarm & Clock

The Lifetone HL uses patented monitoring technology to actively listen for the sound of your smoke alarm. When it hears the smoke alarm it immediately initiates three different alarm signals to wake you up, including a 520Hz square-wave audible alarm, a flashing visual indicator, and a vibrating bed shaker. It will work with existing T3 smoke detectors in a client’s home. Can be used as daily alarm clock (the wake-up alarm is at a lower, non-emergency volume). Alerts with 4 different signals: loud, low pitched 520Hz T3 sound; vibrating bed shaker; talking baritone voice saying "Fire! Get out!"; and FIRE in large text against a flashing orange backlight. Works in conjunction with existing UL-listed T3 ionization or photoelectric smoke alarms. Battery backup lasts 7 days or more while still providing emergency alarm signals (4 D batteries included). Big 1.125" easy-to-read display also alerts you if there is a power outage or low batteries, even if the bed shaker is disconnected. Includes a 6V bed shaker. Dimensions: 8 1/2″ L x 5″ W x 4″ H. One year warranty.
