Make sure you are alerted to every telephone call. These signalers plug directly into the telephone line then alert you when you receive a call. Choose from two styles: wall-mount or desktop. Both models can flash a plugged-in lamp to alert you. As an alternative, the wall-mount models can be used with the optional Add-On Strobe. This makes the wall-mount models ideal for areas where a lamp is impractical such as in small areas like hallways and dorm rooms. Choose the signaler with the right combination of features for you.
There is also a combination Telephone/Doorbell Signaler which is a cost-effective way to signal both sounds.
L - Flashes plugged- in lamp.
T - Transmits to Remote Receiver.
D - Desktop model.
W - Wireless Doorbell capabilities
