M1XRF2G Installation Manual
General Installation and Setup
1. Mounting
- Two (2) #6 x 1/2" screws (not provided), one on each side of the housing should be used for mounting. The
M1XRF connects to the M1's Keypad data bus and may be remotely located up to several thousand feet away from the
control. Mounting inside a metal enclosure or on metalized wallpaper is NOT RECOMMENDED! Try and mount at least
10 feet away from any electrical device that generates noise including the M1 Control as electrical noise may reduce the
receiver sensitivity. For increased signal coverage or redundancy additional M1XRF Receivers (up to 12 max.) may be
connected to the same M1 Controller. See Appendix C.
2. Wiring Connections
- Before making any wiring connections, turn the power Off on the Control Panel. Connect
ter12V, A, B, and Neg from the M1XRF to the M1's Keypad Data Bus (terVKP, Data A, Data B, & Neg).
NOTE: Refer to the M1 Installation Manual and the M1DBH information in this manual about proper
connections of data bus devices with multiple homerun cables.
3. Antenna Installation
M1XRF2G is supplied with four (4) antennas. Two (2) of these antennas installed into the top locations marked Antenna1
& Antenna 2 will be more than adequate for proper receiver performance. The dual antennas ensure signal diversity
which helps eliminate RF dead spots. The two (2) extra antennas are called Ground Plane Antennas. In extreme
applications or where maximum range is desired these additional antennas can be installed in the bottom locations
marked Antenna 3 & Antenna 4.
NOTE: Each antenna location has a two (2) position screw terminal block. MAKE SURE to insert and tighten the
antennas into the screw terminals marked ANTENNA. Do not use the adjacent screw terminal.
