ELK-M1XRF319 Installation Manual
When the Wireless Receiver detects a sensor transmission it will be passed to the M1 Control for processing. The M1 Control quickly
scans through a filter of valid transmitter sensors to determine if it that sensor has been enrolled into it. Should an additional Receiver
pick up the same transmission the M1 will disregard that to help prevent duplication.
Operation
Diagnostic LEDs
Five (5) Diagnostic LEDs provide valuable information as to the operation of the Receiver:
BUS The BUS LED blinks to indicate the Receiver is enrolled on the Data Bus. NOTE: See Data Bus Enrollment.
UC This LED blinks once every ~3 seconds to indicate the Receiver Processor is functioning normally.
RX Whenever an RF transmission is detected this LED should flash.
TX Not Used
Freq. This LED should blink 1 time (once) every 3 seconds when the Receiver is set for Freq. 319.5MHz (see note below)
IMPORTANT!
If the Freq. LED is blinking 2 times (twice) every 3 seconds this indicates the receiver is NOT set for the correct Frequency
(319.5MHz) that is required to receive Elk319 Transmitters and others that adhere to the Interlogix protocol.
For operation with ELK319 Transmitters this receiver MUST be set to the 319.5MHz frequency AT ALL TIMES
The frequency can be toggled back to the correct 319.5MHz setting by pressing and holding the ENTER Button for 3 seconds or
until the Freq. LED starts to BLINK 1 time (once) as expected.
Requirements for Programming the Receiver and Enrolling Transmitters:
The Receiver and wireless transmitters 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.
Transmitter (RF) Level Checking [Signal Strength]:
Wireless transmitters send multiple repeats "or rounds" of their data transmission packets to compensate for interference, weak signal,
etc. The repeated packets are useful to the receiver in providing a relative signal strength as a reference of the acceptable reliability
of the sensor and it's mounting orientation and/or location. When the Receiver hears a wireless transmission it tracks and totals the
number of received data packets over the next few seconds.
During keypad Walk Test mode the total number of received packets may be announced by the M1 through the Voice Output 1
Speaker(s). Example: If all data packets from a sensor (8 out of a total of 8) are detected the announcement should be: "Sensor X,
Level 8", indicating the highest signal strength for this particular Intrusion Sensor.
It is Elk's opinion that a minimum acceptable level of any wireless sensor be a level 3 or 4. This is based on the fact that the Receiver
REQUIRES a minimum of 2 repeated data packets in order to qualify an event as a valid transmission. It is the responsibility of the
installation company, and their technicians, to adopt their own policy of what should constitute a minimum acceptable level [signal
strength] of any wireless transmitter.
IMPORTANT: While the receiver tracks received data packets over a time span, it cannot distinguish whether all packets came from
a single tested sensor or from multiple sensors which happened to transmit at about the same time. If the announced level number
seems unusually high we recommend retesting the sensor(s) multiple time to try and gain a more accurate packet decode level.
Compatible Transmitters:
The following page lists Elk brand transmitter models that have been tested and guaranteed to be compatible with this receiver.
There are additional pages showing other brands of transmitters which were tested to be compatible as of the date of this printing.
Unfortunately the compatibility of the other brand sensors cannot be guaranteed because companies sometimes discontinue a
particular model or make alterations which breaks the compatibility. All information shown is based on the best available data provided
by the transmitter manufacturer(s) and is subject to change without notice. Elk shall not be responsible if a manufacturer changes
or discontinues any listed model.
