ELK Products ELK-M1XSLZW M1 to Leviton Z-Wave Interface. The M1XSLZW is a specialized Elk-M1 serial expander for connecting M1 Controls to Z-Wave enabled devices through a Leviton VRC0P-1LW (vizia rf+3) Z-Wave Serial Interface. Z-Wave is a wireless, low power, "mesh" network technology widely used for automating devices such as: Lights, Thermostats, Electronic Locks, etc. Z-Wave empowers devices to be remotely controlled from across the room or across the world with benefits such as energy savings, convenience, and comfort.
The VRC0P-1LW (vizia rf+3) is known as a Z-Wave Secondary Controller. It is required as a permanent member of the Z-Wave network to maintain contact with all Z-Wave devices and communicate via RS232 to the M1XSLZW. The M1XSLZW translates the protocol into the M1 control and allows commands to be sent and received on the Z-Wave network.
Functionally the M1XSLZW is a serial expander (RS485 to RS232) and shares the same TYPE 5 databus ID as M1XSP serial expanders. A maximum of seven (7) TYPE 5 serial expanders may be connected to an M1.
A key benefit of combining the M1XSLZW and VRCOP-1LW (vizia rf+3) is the ability to interface with new generation Z-Wave devices such as the electronic deadbolts and lock sets from Kwikset, Yale, and Schlage. Locks require a special Security Encrypted (SE) protocol and a process called "Beaming". Both the M1XSLZW and the VRC0P-1LW (vizia rf+3) support these new requirements.
In general, any Z-Wave device that is compatible with Leviton's VRC0P-1LW (vizia rf+3) should also be compatible with the M1. However some devices may have limited functionality due to design or feature differences.
