Multiple Doorbell Flashers Sharing The Same Doorbell Button?


Active Member
I am looking for a flashing doorbell that shares the same one doorbell button.

For example, when the doorbell button is pressed, the doorbell flashers would flash in these following rooms at the same time....

(1) The Living Room

(2) My Office

(3) My wife's office.

Is there such a gadget that can do what I am looking for?

Thanks in advance,
