M1XRFTWM  Installation Manual  Page 3
OVERVIEW
The letters "TW" in M1XRFTWM stand for"two-way" communications, meaning this device is actually a transmitter and 
a receiver (a transceiver).  In other words, it has the ability to both transmit and receive.  The compatible Elk 6000 series 
two-way wireless sensors are also two-way, making them vastly superior to traditional one-way wireless sensors. 
The last letter "M" stands for "multiple receiver capable".  Earlier M1XRFTW units were intended to work together with 
each other but suffered from memory overload if they same sensors were heard by each unit.  This condition could often 
lead to false loss of supervisory troubles.
NOTE: This manual references the word transceiver as well as receiver and transmitter.  This is due to the fact that M1 
keypad programming and the ElkRP programming software still maintain support for traditional one-way wireless as well 
as the new Elk two-way wireless products.  We hope this does not cause confusion.
This Transceiver allows the M1 Control to accept Elk's 6000 Series "Two-Way" Wireless Sensors.  See the listing of 
available sensors later in the manual.  This list is constantly growing and may not be current in this manual due to its 
printing date.   Please contact your local Elk distributor for the latest products and information.  
NOTE: Elk also produces two other models of wireless expanders for the M1 Control.  The ELK-M1XRFEG † allows M1 to 
accept Interlogix (aka GE, UTC) one-way sensors.  The M1XRF2H †  allows M1 to accept Honeywell (aka Ademco) 5800 
series one-way sensors.  Regardless of the model and supported wireless protocol, each connects to the M1 Control via 
the RS485 four (4) wire Data Bus and becomes enrolled and integrated much the same way as a hardwired expander.  
Because it is attached to the RS485 Data Bus, a wireless expander can be remotely mounted virtually anywhere in the 
building to provide maximum convenience and coverage (range).  The serial numbers (TXID) and setup information of 
all sensors are stored safely inside the control.  In the event is should become necessary to replace a wireless expander 
it will not be necessary to reprogram the sensor info.  Simply replace the wireless expander and perform a data bus 
enrollment to allow the M1 Control to begin communicating with it. 
VERY IMPORTANT:  The M1XRFTWM "two-way" Transceiver must be enrolled as the rst zone expander 
(Address # 2) on the M1 Control Data Bus.   NO MORE THAN 3 additional M1XRFTWM transceivers 
may be connected to the M1 for expanded wireless coverage.  The 1st additional M1XRFTWM trans-
ceiver must be enrolled at data bus address 3, the 2nd at data bus address 4, and the 3rd at data bus 
address 5.  If any other type or model of expander (wireless or hardwire) is installed at one of these 
needed addresses then they will have to be relocated (moved) to a higher address to make room for 
the M1XRFTWM(s).   See Appendixes A, B, & C for additional details on the use of multiple transceivers.  
No bus addresses other than 2, 3, 4, or 5 may be used for M1XRFTWM Transceivers.

M1XRFTWM  Installation Manual  Page 5
Setting the Data Bus Address and the Starting Wireless Zone ID
The Transceiver must be addressed and enrolled as the 1st zone expander (Data Bus Address # 2) on the M1 Control.  For 
extended range/coverage up to 3 additional Transceivers may be installed so long as they are  enrolled as the 2nd, 3rd, and 4th 
zone expander ONLY (Data Bus Addresses 3, 4, and 5) on the M1 Control.  If another hardwire or wireless expander is presently 
enrolled at one of these addresses that device must be moved to another address in order to make room for the Transceiver.  
Refer to Appendixes A, B, & C for more details on the use of multiple transceivers. 
Data Bus Address Information: Every device attached to the M1 Data Bus must have a valid address setting within it's device 
type.  TYPE 1 is for Keypads, TYPE 2 is for Hardwire and Wireless Input expanders, TYPE 3 is for Output expanders, TYPE 5 is 
for Serial expanders.  This grouping of devices into different types allows devices in different groups to use the permits same or 
similar address numbers to exist in each device group type.  All devices except keypads utilize a bank of 4 miniature DIP switches 
for setting the address number.  Each switch has an OFF or ON position (binary value 0 or 1) and decimal equiv. value of (1, 2, 
4, or 8).  The total decimal value of the "ON" switches determines the data bus address.  Set the switches to the desired data bus 
address by referring to Tables 1-1 and 1-2.  A small screwdriver may be helpful.
Hardwired Expanders versus Wireless Expanders (Transceivers):  
A single Hardwired Zone Expander adds 16 hardwired zones at a time to an M1 Control.  The data bus address determines the 
zones numbers (starting and ending) of that group of 16 zones.  See Table 1-1.  If additional M1XINs are installed each must be 
assigned a different address, usually the next available, which sets the zone numbers (starting and ending) of that group of 16 
zones.   
A single Wireless Transceiver/Zone Expander can add up to 144 wireless zones to an M1 Control.  The primary or 1st 
Transceivermustbeinstalledandenrolledatdatabusaddress#2,thereforetherstwirelesszonewillalwaysbeZone17.Ifthe
full compliment of 144 wireless zones is added then the last wireless zone will be Zone #160.  (17 + 144 = 160). 
Nohardwiredzoneexpandershouldeverbeassignedadatabusaddressthatwouldresultinaconictbetweenawirelesszone
and a hardwired zone.  In a mixed system of hardwired and wireless zones if any hardwired zone expanders are enrolled in the 
range of zones 33 through 160 then an entire group of 16 wireless zones is lost for every hardwired (16 zone) expander installed. 
1. Mounting - Use two (2) #6 x 1/2" screws (not provided) on each side of the housing for mounting.  The Transceiver connects 
to the Keypad data bus and may be remotely located up to several thousand feet away from the control.  NEVER mount inside 
a metal enclosure or on metalized surface!   Space at least 4 to 6 feet from electrical devices that generates noise, including 
the M1 Control.  Electrical noise may negatively affect operation.  
2.  Wiring Connections - Turn the power Off on the Control Panel before making any wiring connections.  Connect terminals 
+12V, A, B, and Neg from the receiver to the M1's Keypad Data Bus (terminals +VKP, Data A, Data B, & Neg). 
 NOTE: Refer to the M1 Installation Manual and the M1DBH information in that manual about proper con-
nections of data bus devices with multiple homerun cables.  
3.  Antenna - This device uses a single on-board ceramic antenna.  No external antenna is required. 
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 unit.
  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.  
  -TwoblipswithbriefoffindicatesBootloadermode.Unitneedstobeashprogrammedwithapplication
  rmware.UnitwillnotbeoperationaluntilapplicationrmwarehasbeenashedintotheunitusingElkRP.
LEARNED RF - This LED indicates that a valid transmitter has sent a signal packet back to the M1 Control. 
ALL RF - This LED blinks whenever any transmission is detected in the same frequency as the Transceiver.  
DATA BUS ACTIVE - This LED blinks near continuously and indicates activity on the M1 Data Bus.  

Page 6  M1XRFTWM Installation Manual
Data Bus Enrollment:: 
Once the data bus address is set to "2" and the Transceiver has been powered up then it will be necessary to manually ENROLL 
the device in order for the M1 Control to recognize it.  Data bus enrollment can be done from keypad programming "Menu 1 - Bus 
Module Enrollment" or from the ElkRP Remote Programming Software.

Important considerations when installing an M1XRFTWM:
-  A single M1XRFTW wireless transceiver expander is capable of supporting up to 144 wireless Sensors/Zones.  
-  Wireless zones are always allocated in Groups of 16 but it is not necessary to install or use all 16 zones in the group.  However 
it is important to understand that NO HARDWIRED zones can exist at any of these zone number locations.
-  Take special care to ensure that NO wireless zone numbers spill over into data bus addresses that are already assigned to a 
M1XIN Hardwired Zone Expander, or vis versa.    It may be necessary to move a hardwired expander and its related zones up 
higherinthenumberingschemejusttomakeroomforagroupof16wirelesszones.
-  Elk strongly recommends that all wireless zones be assigned consecutively.   The wireless group numbers AND the associated 
data bus addresses will also be consecutive.  Do not mix hardwired zone expanders in between groups of wireless zones.  Data 
bus addresses that are potentially vulnerable to this are  addresses 2,3,4,5,6,7,8,9, & 10 since these addresses are the only 
locations where the wireless zones (17 thru 160) can exist.   
-  Zone 160 is the highest wireless zone number allowed.  Wireless zones cannot exist in the range of 161 through 208. 
-  If a large number of wireless zones is ever anticipated then it would be wise to AVOID any of these potentially overlapping data 
bus addresses (zones) when assigning a hardwired expander. 
Example:  ToinstallanM1Controlwith64wirelesszonestherstzonewillbeginatZone#17sincetheM1XRFTWmustbe
assigned at data bus address 2.  Starting from 17 then adding 64 zones results in the last wireless zone being zone #80.  And 
zone#80isthelastzoneinthedatabusaddress#5location.Sothenextorrstavailabledatabusaddressforahardwiredzone
expander would have to be data bus address #6.  NO HARDWIRED ZONE EXPANDER COULD BE SET to data bus addresses 2, 
3, 4, or 5.  Each of those data bus addresses are  reserved for the 64 wireless zones.  
NOTE: Try to anticipate whether the system might someday require more wireless or hardwired zones.  If the answer 
is yes then it would be wise to plan the data bus address assignments in such a way that future growth is possible 
without having to default the control or totally re-arrange the addresses at a future date.

Operation
How does the Elk Two-Way technology differ from one-way wireless technology?
Elk's Two-Way technology is superior to traditional one-way wireless products in many ways.  
1.   Every signal sent by an Elk two-way sensor receives a positive acknowledgment from the transceiver.  One-way systems have 
the reputation of being "re and pray".  
2.  Elk two-way sensors only send one signal at a time.  One-way sensors have no choice but to blindly send multiple signals in 
hopes that at least one will reach the receiver.    
3. LongbatterylifeandenergyefciencyareinherentdesignsoftheElktwo-waysensors.Elktwo-waysensorsself-adjusttheir
RF power, using only the minimum power needed to deliver a clear signal.   One-way sensors consume FULL power on each 
and every transmission.
4.  Long range coverage is possible due to the 900 MHz frequency range and automatic frequency hopping design.  One-way sys-
tems operate at a specic, non-adjustable lower frequency.  
5.  A two-color LED indicator on the sensor provides operational feedback.   A single Green blink means the transmission was sent 
and positively acknowledged by the transceiver.  A Red blink means the sensor was unable to receive an acknowledgment from 
the M1XRFTW transceiver.  One-way sensors provide no indication of signal verication.
6. Installationcondence.AllElk6000seriessensorsarticiallylimittheirRFpowerto50%ofnormalfortherst10minutesafter
battery installation.  This "stress test" helps to assure that a sensor's mounting location and range is suitable for long term reli-
ability.  The principle is that a sensor that is able to reliably communicate using half the normal power will have a high degree of 
reliabilitywithfull100%power.Other sensor brands do not provide this condence feature.  To take full advantage of this feature 
we recommended that every sensor be temporarily installed at its intended location and violated (tripped) multiple times while 
observing the two-color LED indicator.  A near instant GREEN blink response from the sensor is Ideal.  The sensor will repeatedly 
attempttoreachthereceiverforupto20seconds,butanytimeittakesmorethanjustafewsecondstogetthroughitmeansthat
the mounting location is poor.  Therefore, we strongly suggest reorienting the sensor to another spot on the mounting surface, 
or rotating its mounting by 90 degrees whenever it takes more than a few seconds to get a GREEN acknowledge.  Excessive 
range and poor wireless conditions will always result in a delay of the GREEN blink.  A Red blink means the sensor was unable 
to receive an acknowledgment from the M1XRFTW transceiver.  NOTE: In extreme situations  it may be necessary to relocate 
the transceiver to closer spot or to add an additional remote transceiver to cover distant sensors.  
NOTE: The Green Acknowledge LED does not operate for sensor restoral transmissions.
Programming tools needed for the M1XRFTW Transceiver and Sensors.
There are no special tools required for Elk's two-way wireless product line.  The Transceiver itself and the sensors may be programmed 
using either the M1 Keypad Installer Programming or the ElkRP Remote Programming software.  The following pages document the 
options and steps for programming from the keypad.  
Installation and Replacement of Batteries in Wireless Sensors:: 
A Low Battery trouble will be sent to the Control whenever a sensor determines that its battery needs to be replaced.  This will 
generally occur well in advance of the battery becoming completely dead.  However, it is up to the customer to ensure that the Low 
Batterytroubleisrespondedtoandrectiedinatimelymannersothatthesystemcancontinuetooperate.
When replacing a Low Battery:
1.  Remove the old battery and WAIT AT LEAST 20 SECONDS before installing the new battery.  This is important as it allows 
the sensor circuitry to completely shutdown and erase the low battery memory. 
2. After 20 seconds, install the new battery, then trip the sensor a couple of times so that an "all good" signal will be sent to the 
control to clear the low battery trouble.

Fundamentally only 1 M1XRFTW Wireless Transceiver is needed to add 144 wireless zones to an M1 Control.  But this presumes 
that each wireless sensor is installed within the coverage range of the single transceiver.  In large buildings or where all sensors 
cannot be covered by a single M1XRFTW transceiver then up to 3 additional M1XRFTWs may be connected to the data bus and 
deployed into the more distant areas.  IMPORTANT!  If additional M1XRFTWs are installed they MUST be set and enrolled ONLY 
at data bus addresses 3, 4, and 5.

Appendix A - Data Bus Selection Table
This table should help visualize how the Wireless Zones and Hardwired Zones share the data bus address assignments.  Please note that  No 
Wireless Zones Are Allowed Above Zone 160.  This table shows the starting wireless Zone # and data bus address along with the additional 
data bus addresses and Zone #’s necessary to obtain the total and best mix of wireless and hardwired zones.  The left column indicates the total 
maximum wireless zones that may be obtained based on the data bus addresses chosen. 
1. Theboldedcolumnindicatesthatthe1stM1XRFTWTransceivermustbeatdatabusaddress2.Thisalsomeansthattherstwirelesszone
will be Zone #17.
2.  If possible, try to determine how many total wireless zones might ever be needed now or in the future on this installation.  And be sure to also 
consider the possibility of future hardwired zones and M1XIN hardwired expanders in the future.  
  NOTE: The total (max.) number of wireless zones will be decreased by 16 zones for any hardwired expanders installed and enrolled 
in the data bus addresses at or below Addr 10.  The reason is that only zones 17 to 160 can be used for wireless zones, and data bus 
addresses 2 thru 10 correspond to zones 17 to 160. 
  It is strongly recommended that all wireless zones be sequential, with no hardwired zones interspersed between them.  
  The following are suggested guidelines: 
   -  If there is any possibility that additional wireless zones might be needed in the future, consider leaving a gap of 1 or more data bus 
  addresses between the M1XRFTW data bus address belonging to the last wireless zone and any M1XIN hardwired zone expanders.
   -  If there is little or no likelihood of additional wireless zones being required, the 1st hardwired zone expander can be If setup and enrolled at the 
rstavailabledatabusaddressrightafterthelastwirelesszone
