ELK PRODUCTS CRYSTAL WIRELESS RECEIVER

COMPATIBLE WITH GE SECURITY 319.5MHZ CRYSTAL TRANSMITTERS

The ELK-M1XRF2G is a Wireless (RF) Receiver and Input Expander for use with the ELK-M1 and ELK-M1EZ8 Controls. The receiver connects to the four (4) wire data (keypad) bus of the control and integrates in much the same way as a M1XIN hardware zone expander except that a single M1XRF can handle up to 144 wireless zones (e.g. transmitter sensors or points).

The M1XRF2G receiver uses Crystal frequency technology and is a dual (2) antenna, phase diversity design capable of long range wireless coverage.

The design of the M1XRF receiver provides for all transmitter programming and enrollment data to be stored in the control panel, not in the M1XRF. The only data stored in the receiver is a pre-filter or list of "valid transmitters" that is automatically updated by the control each time the sensor enrollment mode is exited. In regular operation the M1XRF is listening for sensor transmissions and passes data coming from "valid sensors" to the control for processing. The purpose of the pre-filter is to reduce the amount of unnecessary data bus traffic, particularly in locations where transmitters from an adjacent neighbor may be heard. The prefilter is automatically disabled during setup and enrollment so that it will be possible for newly enrolled sensor transmissions to reach the control. In the event a receiver ever needs to be replaced it should only be necessary to enroll the replacement receiver onto the data bus and then enter and exit the wireless setup programming. This would cause the pre-filter information to be updated and the new receiver to become operational. In the event that multiple M1XRF receivers are installed the storing of sensor data in the control makes it possible to use portable devices such as keyfobs without regard as to which receiver hears the transmission.

The M1XRF2G is ONLY compatible with the 319.5MHz Crystal based transmitters available from GE.

ELKM1G and ELKM1EZ8 Controls MUST be operating application firmware version 5.0.12 or higher in order to work with the ELKM1XRF Receiver.
