M1XRFTW 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
receiver 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! Mount at least 10 feet
away from any electrical device that generates noise including the M1 Control. Electrical noise can and may reduce the
receiver sensitivity. For increased signal coverage or redundancy additional M1XRF Receivers (up to 11 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 receiver 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 con-
nections of data bus devices with multiple homerun cables.
3. Antenna - The M1XRFTW uses a single on-board ceramic antenna. There is no external antenna re-
quired.
DIAGNOSTIC LED INDICATORS:
There a four (4) LEDs on the board that provide valuable information as to the operation of the M1XRF:
STATUS
(Data Bus Status) - Multiple conditions exist for this LED:
OFF = No Power to the M1XRF
ON Solid = Power is good but it is not yet enrolled with the M1 or the Microprocessor is not functioning.
BLINKING = 2 different blink rates:
- Slow "one blink per second" indicates Normal Operating mode.
- Rapid "two quick blinks with a brief off time" indicated the Receiver is in Bootloader mode, indicating it has
not yet been flashed with application firmware. This should only occur if you are field updating the unit.
It will not be operational until application firmware has been flashed into the unit using ElkRP.
LEARNED RF
- This LED will momentarily turn on when the M1XRF receives a valid transmitter and is in the process of
sending the signal packet back to the M1 Controller. As soon as the packet is acknowledged by the M1 Controller
the LED will turn Off.
ALL RF
- This LED blinks whenever ANY Elk RF transmitter is heard or detected.
DATA BUS ACTIVE
-
This LED blinks near continuously and indicated activity on the M1 Data Bus.
