ELK-M1XRF319 Installation Manual
Page 3
OVERVIEW
The ELK-M1XRF319 Wireless Receiver allows wireless transmitters that operate on the 319.5MHz Frequency and that adhere to
the Interlogix protocol to work with ELK-M1 Controls. A list of compatible transmitters brands and models is published on page 7 of
this manual. The receiver connects to the M1's RS-485 four (4) wire data bus and integrates much the same as a hardwired zone
expander. It can be installed remotely from the control virtually anywhere inside the premises up to the maximum allowed distance
of the data bus. One receiver can cover an average size home and up to 144 wireless transmitters. All transmitter programming
and enrollment data is stored in the M1 Control and not in the receiver(s). This means that additional receivers, up to 9 total, may be
connected for extremely large coverage areas and without needing to relearn transmitters.
WARNING: Elk offers two other models of Wireless Receivers for the M1 Control. Each Receiver operates on a different
frequency. It is critical that the frequency and protocol of each installed transmitter be matched with a receiver that is
compatible with that same frequency and protocol. A mixture of receivers and transmitters on the same installation is
possible as long as each transmitter is installed within range of the receiver which matches its frequency and protocol.
Receivers are physically and electronically different and can only receive the transmissions of their matching transmitters.

IMPORTANT: If this Receiver is the LAST device on the RS-485 Data Bus then connect a 120 Ohm Resistor (included in hard-
ware bag) across terminals A and B along with the wiring. The last device on the data bus MUST include this bus termination.
