M1 Two-Way Wireless Transceiver


The M1XRFTWM two-way wireless transceivers allow an ELK-M1 or ELK-M1EZ8 control to accept Elk’s complete line of two-way wireless sensors. The ELK-M1XRFTWM has been optimized to provide superior signal reception and reliability in multi-transceiver applications.

The ELK-M1XRFTW has been replaced by the ELK-M1XRFTWM. The ELK-M1XRFTWM performs all the functions of the ELK-M1XRFTW and is suitable for single or multiple transceiver installations.

Do NOT mix ELK-M1XRFTW and ELK-M1XRFTWM transceivers in a single M1 installation.
