USB power cable for flasher receiver in DC 5V.
One of our deaf customers told us that his parents uses the Wireless Doorbell to notify him that dinner is ready. Another client uses this device in their Doctor’s office to silently notify the nurse that a patient has arrived in the waiting room. There are so many creative ways to use this device along with the Wireless Flashers.
Wireless transmission between devices can reach up to 150 meters (~500 feet) in open space. It is powered by three AA batteries or DC 5V.
