Essential Info

The M1XRFTW two-way wireless transceiver allows an ELK-M1 or ELK-M1EZ8 control to accept Elk’s complete line of 6000 Series "Two-Way" Wireless Sensors. The letters "TW" on the M1XRFTW signify "two-way", meaning this device is actually a transceiver rather than just a receiver. In other words, it has the ability to both transmit and receive. The compatible Elk 6000 series two-way wireless sensors are also two-way, making them vastly superior to traditional one-way wireless sensors.
