Replacement Door Knock Transmitter
Know when someone knocks at the door! The Door Knock Transmitter with Clip is a replacement or an accessory transmitter to expand your Clarity Alertmaster notification system.
The transmitter sends a signal to a connected Clarity Alertmaster receiver (not included), which then notifies you of the door knock with a visual or vibrating alert.
Easy to Install: Simply clip the transmitter to the inside face of the door using the included clip and flip the power switch on. Knocking on the door will activate the unit.
