MMCall signal Reapter

MMcall repeater    Introduction:
1) It can double the transmitting distance between the button
and the host. It receives the signal from the button wirelessly and then
enhance the signal to transmit to the host. 2) When the site is very large (more than 2,000 square meters usually) or the
signal is severely shielded in the building, several signal repeaters can be
adopted to realize the no-blind coverage. Furthermore, the signal relaying
function of the signal repeater can ensure the clients with large sites to
use the MMCall products swimmingly
