You may add up to 11 receivers on an M1 system for redundancy or greater coverage. The receiver may be installed virtually anywhere in the building for convenience and optimum coverage. Power is supplied to the Receiver / Expander through its connection to your M1 system. This Wireless Receiver and Input Expander uses Crystal frequency technology and is a dual antenna phase diversity design capable of long range wireless coverage.

    This wireless receiver works well with my wireless contacts and wireless key fob and was easy to install. I found the range to be decent.
