Lisa Alert System TX Doorbell Acoustic Transmitter

For the hard of hearing it can be incredibly difficult to hear everyday things such as the doorbell, which can make life incredibly frustrating and isolating over time. A great addition to any Lisa alert system, the Lisa Alert System TX Doorbell Acoustic Transmitter gives a fantastic doorbell alert for the hard of hearing as a part of a wider alert system.

Listens For Chime

The Lisa Alert System TX Doorbell Direct Transmitter is a great solution for those wanting a doorbell solution. But what if you're not comfortable wiring the transmitter into the doorbell system?

Rather than connecting directly into the components, the acoustic transmitter listens for the doorbell chime itself – simply place the included sensor near the doorbell speaker and it'll detect whenever the doorbell chimes. This also makes it great for portable doorbell systems which don't permit direct connection.

Reduces False Alarms

A sensitivity control enables you to tune the sensor so it only picks up the doorbell and won't be activated by other sounds, helping to make your Lisa system more reliable and accurate.

Alerts All Lisa Receivers

Any and all Lisa alert system receivers in range are alerted by the transmitter. What's more, because of the configuration of Lisa receivers the tone or pattern for the Doorbell event is unique. This meas that you can know right away that the door requires your  attention.

And because it uses the Lisa system, you can extend your setup to include a range of different transmitters and receivers. Check out our full Lisa alert range for more.
