ELK-M1XRF319 and the ELK-M1XRFTW Wireless Transceivers Two Part Question

[Doug G]

I have the ELK-M1XRF319 and the ELK-M1XRFTW Wireless Transceivers. Will the ELK-M1XRF319 sensors work on the ELK-M1XRFTW Wireless Transceiver? If not, I did buy ELK-M1XRF319 transceiver, but it is NOT currently installed yet and I was waiting to see if my question above is possible or not. If not compatible, how would I install the ELK-M1XRF319 with the ELK-M1XRFTW? Should they be far away from each other or can they be close to each other? Would the ELK-M1XRF319 connect into the same RS485 bus that the ELK-M1XRFTW is connected too? Can I use the ELK-M1DBH Data Bus Hub to connect the ELK-M1XRFTW and ELK-M1XRF319 to that? Right now all I have is the keypads connected to the ELK-M1DBH Data Bus Hub and I would like to consolidate. I am really looking for best practices if there are any.

The reason I ask is because I like a couple of the sensors that the ELK-M1XRF319 offers and not sure if they will work on the ELK-M1XRFTW Wireless Transceiver.

Thank you.

The ELK M1 Gold System will support 3 wireless technologies — ELK Two-way (6000 series) using the M1XRFTWM Transceiver,  319.5 MHz sensors using the M1XRF319 and Honeywell 5800 Series using the M1XRF2H Receiver. It is possible to have the different wireless technologies communicating with the M1 at the same time however the M1XRFTWM will only communicate with the ELK Two-way sensors — the M1XRF319 will only communicate with the 319.5 M Hz and the M1XRF2H will only communicate with the Honeywell 5800 series sensors.  The M1XRFTWM and the M1XRF319/M1XRF2H  are bus devices and connect to the M1s RS485 Data Bus the same way as a Keypad or other bus device. There are three methods to wire the M1s RS484 Data Bus 1) M1DBH Data Bus Hub using Cat5/6 all the way from the M1DBH to the device, 2) M1DBHR Data Bus Hub Retro Fit using 4-Conductor; 3) maximum of 2 Home Runs and Daisy Chaining Devices. More information on M1 Data Bus configuration can be found on page 12 and 13 of the M1 Installation Manual.  Because the M1XRFTWM and M1XRF319/M1XRF2H are Bus Devices they can be remotely located to help improve wireless coverage and it is possible to add additional M1XRFTWM and M1XRF319/M1XRF2H modules to the data bus to help eliminate any weak signal areas or dead zones. Please refer the M1XRTWM and M1XRF319/M1XRF2H Installation Manuals for specifics on supported addresses and so forth for these devices.  If mounting the M1XRFTWM and M1XRF319/M1XRF2H in close proximity to each other we’d suggest keeping them approximately 24 inches apart.

@Brad Weeks Thank you for the thorough explanation. I completely understand.
