This is the ultimate smoke detector system from Silent Call. When the smoke detector activates, it sends a signal (up to 100 ft) to a receiver as it also emits a loud audible siren. The receiver with bedshaker will awaken you. The receiver sets on your nightstand and plugs into an electrical outlet. When it detects a signal from the smoke detector, the bedshaker will be activated.
If the smoke detector activates, the bedshaker will begin to vibrate on the receiver and will continue until you turn it off. The smoke detector operates on a 3V lithium battery and has an 85dB alarm. It has a 3 year warranty and a 5 year warranty on the transmission board.
The receiver with bedshaker has a 5 year warranty.
