M1XRFTWM Installation Manual
One (1) Wireless Transceiver on the M1 Control can handle up to 144 wireless zones as long as wireless sensor is installed within
the coverage range of that single transceiver. To cover large buildings, or where construction design decrease wireless performance,
up to 3 additional (absolute max. of 4 total) Transceivers may be added to the M1 data bus to increase the coverage range.
IMPORTANT! When installing multiple Transceivers it is important to strategically place them as far away from each other
as possible. This is to help insure maximum coverage AND reduce the amount of coverage overlap with each other.
Note: M1XRFTWM Transceivers may ONLY be enrolled at data bus addresses 2, 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. The bolded column indicates that the 1st M1XRFTWM Transceiver must be at data bus address 2. This also means that the first wireless zone
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 M1XRFTWM 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
first available data bus address right after the last wireless zone
3. Start down the left column and pick the line that represents the maximum number of wireless zones required. Follow this row across
to find the first column indicating “hardwired”. The top of this column shows the data bus address where an M1XIN Hardwired Zone
Expander may be enrolled.
- Up to 3 additional “redundant” M1XRFTWM Transceivers may optionally be installed at data bus addresses 3, 4, & 5. Redundant Transceivers
may be remotely mounted and wired back to the M1 Control to provide additional range and coverage in extremely large or difficult buildings.
See Appendix C regarding Redundant Transceivers.
NOTE: The only benefit to using multiple transceivers is added range/coverage. They do not increase the number of wireless zones.
