Complete fire protection for your home and family with smoke detector, alarm clock and bed shaker It only takes a spark from a faulty appliance plug, a pot forgotten and left to bubble over on the stove, or a burning candle left unattended for an accident to happen. If you have a hearing loss, there's always a risk that you can miss the smoke alarm alerting in the event of a fire. The Bellman Safe Fire Alerting system is a complete home alerting system for fire safety. It includes a smoke detector that is connected to an alarm clock and a bed shaker. If a fire should occur, the battery-operated smoke detector will signal the alarm clock and bed shaker that awakens you with an extra loud alarm signal, flashing lights and vibrations.
