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.
