LR900 Node Hardware Installation and User Guide
9000-0000-126 Revision 01 7 of 21 Genave Electronics
Overview
How it Works
The LR900 Node is a stand-alone transceiver/controller that utilizes FHSS (Frequency
Hopping Spread Spectrum) to communicate and synchronize actions with other LR900 nodes
or LR900 Keypads.
Keypads are normally the origination point for commands. When a button is pressed on the
LR900 wireless keypad, a signal is transmitted to all Nodes within range. Any LR900 Node
which hears this signal does two things; First it activates its own corresponding output and
then it retransmits the signal to reach additional LR900 Nodes who may not have heard the
original signal. If an LR900 has already heard the signal, it ignores all future receipts of that
particular signal to keep the signal from repeating forever.
Each node has 8 inputs and 8 outputs. If one of the inputs is activated (shorted to common),
The LR900 activates the corresponding output for 2 seconds (Ex: Input 1 activates Output 1).
Optionally, the LR900 can transmit to all of the other LR900 Nodes that its input has been
activated (See Advanced Info).
Communications between LR900s is performed peer-peer. By using this method it’s
unnecessary to have a master controller and LR900’s can be installed, relocated or removed
without needing to register them into or out of a system.

a. Zones are identified by the letters A to G.
b. Receiving. The receiving units can be switched in and
out of zones with the LR900 menu. When an LR900
receives a signal that is intended for only specific zones, it
checks which Active Zones it has been set to accept. The
signal is acted upon if the zone has been enabled (set to
‘Y’), or ignored if the specific zone is disabled (set to ‘N’).
c. Transmitting. Node inputs can be set to send
commands to one or more particular zones (sub-groups)
rather than the standard all-call to all the nodes. Due to the
extensive configurability of this feature, the transmitting
zone groups cannot be adjusted using the LR900 menu.
The sending node must be programmed externally, by
either directly editing the configuration on the SD card and
re-loading, or by using the LR900 editing program.
11) Active Inputs
a. Individual external inputs can be enabled or disabled
using this menu. “Y” indicates that the input is enabled.

Installing
Mounting the LR900
To remove the node from a Din rail, use a screw driver to pull and hold down on the red latch
on the enclosure while pulling the bottom of the case forward.
Power Connection
The LR900 operates from 7.5VDC to 28 VDC. The power input is also reverse voltage
protected. The polarity of the connections is displayed on the label.
Internal Battery Backup
The LR900 devices include a high capacity, rechargeable battery so the unit remains
operational during temporary power interruption. Battery life is affected by traffic load and
other system variables, but the battery power will generally last 4 –6 hours. When power is
first applied, the LR900 must charge the battery to a minimum voltage before coming
alive. If you observe the screen blinking on and off, it is due to the battery being
charged. Turn the Power switch off and wait 2 to 3 minutes before reapplying power.
Power Switch On/Off
The power switch is used to disable the LR900 when testing, modifying, or shipping the
system. Even when the switch is Off, the LR900 will continue to charge the internal battery.
The power switch is recessed to prevent accidental operation.

Pairing the First Units with a Keypad
Three unique settings must match between LR900 units before they will communicate and
retransmit signals from a keypad or other LR900 that have the identical settings.
System ID: A number from 1 to 30001.
RF Channel: Specify radio channel 1 to 8.
Encryption Key: Alpha-numeric code from five to sixteen digits. (0-9, A-Z, a-z, with
the exception of the letters I, i, O, o, L, l which are too easily confused with other
letters).
The system ID and RF channel can be viewed and changed using the menu screen.
The Encryption Key can be changed using the menu screen, but for security purposes it
cannot be viewed on the screen nor copied to the SD card. Thus, it’s very important to
record any new encryption keys for future changes.
Unit ID numbers are employed for some advanced features as well as quickly identifying unit
locations by simply viewing the main screen. They should be unique, but it is not required.

Encryption Key = 13579
Unit ID = 1
Antenna Requirements
There are a few items to remember about the antenna.
1) Keep the antenna away from metal surfaces for the best RF signal range.
2) For long antenna cable runs, use LMR-400 coaxial cable with adapters.
3) Never exceed 11dbi of antenna gain without some sort of cable loss (FCC
requirement).
Note: If an LR900 is out of range of its group, any LR900 can be used as a repeater to
extend the range of the signals and reach the lone LR900.
Returning to Factory Defaults Using Menu Screen
The LR900’s can be restored to their factory default programming at any time by using the
menu screen. Returning to the factory default is the recommend method to recover from
programming errors or other events such as when a unit is not communicating within the
group.
After defaults have been restored, basic communications can be verified and custom changes
can continue from that basic, known state.
The Factory Defaults
To restore the defaults, Press the DOWN arrow until the Adjustments screen appears, then
press the RIGHT arrow once and then press the DOWN arrow to select Reset Memory.
Press ENTER key and use the LEFT, RIGHT, UP and DOWN keys to enter 987. Press
ENTER key to restore LR900 to factory default settings.

LR900 Node Hardware Installation and User Guide
9000-0000-126 Revision 01 17 of 21 Genave Electronics
Returning to Factory Defaults Using Buttons
Another method to restore the default settings is to use the arrow buttons. Press and hold the
BACK button and the UP button at the same time while applying power to the unit. Release
the buttons once the unit indicates that it’s working on restoring the defaults.
Adding More Units to a System / Cloning Units
In most instances, the LR900’s will operate as required using the factory defaults with a new
encryption code as the only recommended change. Adding another Node to the system is as
simple as matching the unit’s System ID, RF Channel, Encryption Key to the existing
system nodes and assigning the new Node a unique Unit ID.
In applications where many changes have been made to the LR900’s operation, it’s easy to
clone a new LR900 by using a Transflash memory card to transfer the configuration from the
operating unit to the fresh LR900.
Insert a fresh SD memory card into the operating unit
(source unit).
Menu View/Edit Settings->Clone to SD.
Remove SD card after the configuration has finished and
plug into the fresh LR900 (destination unit).
Menu View/Edit Settings->Load New Pgm.
Restart the destination unit and manually change the
Encryption Key and give it a unique ID number.
Press and hold
simultaneously as
power is applied.

Inputs
Input Header Characteristics
The inputs for the LR900 are used to trigger actions and transmissions. When an input is
pulled low (shorted to pin 9 of J9) the LR900 turns on the associated output for 2 seconds
(Input 1 turns on Output 1).
Some features of the inputs:
1) DO NOT apply any voltage to the inputs. Only connect an input to pin 9 of J1.
Although the inputs have diodes to protect them from incoming voltages, they
should only be pulled low.
2) The inputs are protected from moderate voltage spike. Large voltage spikes will
overwhelm the input protection and damage the processor. Therefore keep
wires leading to the inputs as short as possible and twist the wires to reduce
voltage spikes.
3) Node Inputs are normally not transmitted to other Nodes (See Advanced
Information).
4) If an input is retriggered within 2 seconds, the associated output will not be
turned off.
5) Each input has a pull up resistor of 470 Ohms.
Input Header Pinout

Outputs
Output Characteristics
The LR900 has 8 individual output Mosfet transistors. Each of the transistors pulls its output
to common ground (Pin 9 of J2) when activated.
Some features of the outputs:
1) Never apply more than 30 Volts DC to an output
2) Never control more than 70 milliamps of current through an output.
3) Each output is on for 2 seconds with each triggering of an input.
4) The transistor resistance when On, it is typically 7 Ohms.
Output Header Pinout
Radio
Radio Module
The LR900 internal radio has the following features:
1) Maximum power output is 250 milliWatts
2) 50 Hop/channel FHSS transmission
3) 902MHz to 928MHz frequency range (ISM Band)
4) RPSMA output connector
5) 128 Bit AES Encryption
Changing Channel
The LR900 uses a group of 50 frequencies within 902 MHz to 928MHz. When you change the
channel, you are only changing WHICH of the 50 frequencies are used and in which order
they are hopped. From the ADJUSTMENTS menu, select Radio Settings. Press the ENTER
button and then use the DOWN and UP buttons to change the channel. Press the ENTER
button to make the change.

9000-0000-126 Revision 01 20 of 21 Genave Electronics
Testing Signal Strength Between Units
There are three methods to test if there is sufficient signal strength between units.
1) Link Test (All Nodes)
Go to the LINK TEST screen and press Enter. If there is another Node within
range of the unit, the word RECEIVING will flash on the bottom of the display
each time the LR900 transmits.
Note: The LR900 does not display which Node has responded, nor the signal
strength, only that another Node can hear it.
2) Range Test (Specific Node)
Go to the RANGE TEST screen within the ADJUSTMENTS menu. With each
press of the Enter button, the LR900 will send a request to a single node in the
system. If the Node show on the screen receives the signal, it responds with
the strength of the signal IT received. The results are displayed on the screen
as a percentage (ie. 100% is good, 40% marginal). Perform the test 10 times
and average the results. Individual results vary depending on local
interference.
To change which Node will receive the request, press the DOWN button when
in the RANGE TEST screen. The screen will change to “Editing”. Use the
keypad buttons to change the destination address to the new desired Node
number and then press the ENTER button to make the change.
Advanced Features and Information
Zones
LR900 units can be sub-grouped to only accept a command if they are within this subgroup.
All other nodes will repeat the signal, but they will ignore the command because they are not
in the subgroup.
(This feature requires the use of the LR900 computer program)
Roll Call
Roll Call is used to find other Nodes on the system with the same System ID, Channel
number and Encryption Code. Press the ENTER button to begin a Roll Call. The first units to
respond within 10 seconds are displayed on the screen. The information displayed for each
Node is the Unit ID followed by the signal strength for that unit.
RF Beacon
RF beaconing is used in systems with Master Internet Nodes. When selected, a Node will
transmit at a selected interval that it is alive, its battery voltage, external power voltage, input
and output status.
