WARNINGS AND DISCLAIMER INFORMATION.
Description
The TX+2WAYFOB is an unsupervised wireless keyfob device that when within
operational range of an Interlogix control panel or receiver, can remotely arm,
disarm, and perform other functions specific to the system.
The TX+2WAYFOB features the TX+ Encryption protocol which provides encrypted
wireless communication to select Interlogix control panels, as well as 2-way
communication functionality providing acknowledgement at the device via the tricolor LED that transmissions sent have been received by the panel. Please refer to
your panel’s installation instructions to see if it is TX+ Encrypted capable.
The TX+2WAYFOB also utilizes the standard ITI-319 protocol which is compatible
with all Interlogix control panels and receivers. When enrolled into a panel and
operating in the standard ITI-319 mode, the device functions in 1-way mode only and
does not receive acknowledgement signals back from the panel.

Enrollment Into TX+ Encryption Supported Panels
To enroll the TX+2WAYFOB as an encrypted keyfob into a panel that supports the
TX+ Encryption protocol, follow these steps:
1) Place the panel into program mode, then go to Learn Sensors menu.
Refer to your specific alarm panel manual for details on these menus.
2) Once the Learn Sensors mode has been activated, press and hold both
the STAR and LOCK buttons together for 5 seconds. The LED
will blink red one time upon transmission, followed by an alternating RED
and GREEN blinks (6 times total) for successful acknowledgement of
enrollment into the panel.
3) If the panel does not respond after completing step 2, repeat as
necessary until the device is successfully enrolled into the panel.
Note: Utilization of the TX+ Encrypted protocol is only compatible with select
Interlogix control panels. When enrolled into a panel that is TX+ Encrypted
capable, the enrollment menu screen may indicate “TX+ Encrypted” to verify
that the sensor is communicating to the panel via the encrypted protocol.
Please refer to your panel’s installation instructions to verify that the panel
supports TX+ Encrypted capability.
If the keyfob is unintentionally enrolled into a TX+ Encryption supported panel in the
standard ITI-319 protocol mode, the device will need to be removed from the panel,
and the keyfob Reset/Restore function will need to be performed before attempting
to re-enroll in the TX+ Encryption mode. The Reset/Restore function is performed by
pressing and holding the UNLOCK and LIGHT buttons together for 5 seconds.
The LED will remain illuminated green for 3 seconds following the successful
reset/restoral.
Enrollment into Non TX+ Encryption Supported Panels (ITI319 Protocol, one-way mode only)
To enroll the TX+2WAYFOB into a panel utilizing the standard ITI-319 protocol,
follow these steps:
1) Place the panel into program mode, then go to Learn Sensors menu.
Refer to your specific alarm panel manual for details on these menus.
2) Once the Learn Sensors mode has been activated, press and hold both
the LOCK and UNLOCK buttons together for 5 seconds.
The LED will blink red one time upon transmission. Then select the
appropriate sensor group and number on the panel. Refer to your specific
alarm panel manual for details on the different sensor groups.
3) If the panel does not respond after completing step 2, repeat as
necessary.
Note: When the TX+2WAYFOB is enrolled into a panel utilizing the standard ITI-319
protocol, the 2-way communication functionality is not available and it will operate as
a standard 1-way device.
Operation in TX+ Encrypted Mode
When the TX+2WAYFOB is enrolled into an Interlogix panel/receiver that supports
the TX+ Encrypted protocol, and the device is communicating via the TX+ Encrypted
protocol, the following chart indicates the different transmissions possible, along with
their corresponding LED acknowledgements after the initial RED blink upon
transmission:

No acknowledgement received from the
panel. When this occurs, two conditions
may exist:
1) the panel has received the keyfob
transmission and has entered into the
desired state, but the keyfob is too far out
of range to receive the acknowledgement
messages back from the panel.
2) the keyfob is too far out of wireless
range and the panel did NOT receive the
keyfob transmission, resulting in no state
change at the panel

Trouble Conditions in TX+ Encrypted Mode
After the TX+2WAYFOB is enrolled into an Interlogix panel/receiver that supports the
TX+ Encrypted protocol, and the device is communicating via the TX+ Encrypted
protocol, the following chart indicates the different trouble conditions that can occur,
identified by the following LED responses on the keyfob:
1) Remove the case cover from the back housing by inserting a small flat
head screwdriver into the slot at the bottom of the device and press on
the tab.
2) Remove the existing battery and re-install a new Panasonic CR-2450
battery. When inserting the battery, pay close attention to the battery
polarity indicators to ensure proper placement.
3) Replace the case cover and perform a sensor test to ensure proper
communication to the panel/receiver.
TX+2WAYFOB
Operation in ITI-319 Mode
When the TX+2WAYFOB is enrolled into an Interlogix panel/receiver and the device
is communicating via the ITI-319 protocol, the following chart indicates the different
transmissions possible, along with their corresponding LED acknowledgements.
Please refer to your panel’s installation instructions for further detail on which keyfob
functions may or may not be available.
LOCK
Depending on your control panel:
Press once to arm in Stay mode. LED blinks RED once upon transmission.
Press twice to arm in Away mode. LED blinks RED once upon transmission.
UNLOCK
Press this button to disarm the system. LED blinks RED once upon transmission.
LIGHT
For NetworX panels, press this button to arm the system in Stay mode. For Concord
or Simon XT, it can turn system-controlled lights on or off. LED blinks RED once
upon transmission.
STAR
The star button function depends on the individual panel programming. Refer to the
installation instructions for your panel. LED blinks RED once upon transmission.
PANIC or AUX
If the keyfob is programmed using a panic or portable auxiliary group number,
pressing the LOCK and UNLOCK buttons simultaneously will activate an audible or
silent alarm (depending on the group number) and initiate reports to the central
station. LED blinks RED once upon transmission.
Replacing the Battery
The TX+2WAYFOB comes pre-installed with a single Panasonic CR-2450 Lithium
coin-cell battery that provide up to 10 years of battery life under normal usage
conditions. Because keyfobs are non-supervised devices, a low battery signal will
only be received by the control panel when the device is within range of the receiver
and a button is pressed (if the device is not in use, no low battery signal will be sent
until a button is pressed). When the device is carried beyond the range of the
receiver and/or is seldom used/tested, the battery could wholly deplete without a
warning of the battery condition being sent to the panel. If the LED on the device
appears dim or does not turn on when a button is pressed, it is a warning that the
battery may be low or depleted and should be replaced. To ensure proper
functionality, test the device weekly and follow these simple steps to replace the
battery when necessary:
