This Sonic Alert Sonic Blink compact receiver features a built-in, high intensity strobe alert that projects light a full 360 degrees, eliminating blind spots. This strobe light is up to 8 times brighter than add-on strobes. It can even be placed behind objects such as furniture.
The Sonic Blink is perfect for places where an extra lamp may not be needed, such as in bathrooms, dining rooms, and hallways. Just plug it into a wall electrical outlet and it is ready to receive signals from Sonic Alert's doorbell, baby cry and telephone signalers. Must be used with a Sonic Alert signaler.
What else do I need to make this work?
