Interlogix TX+2WAYFOB - Data Sheet Dated 02/2019
Designed for use with Interlogix
control panels and wireless
receivers, the TX+2WAYFOB is a wireless, battery-powered
device that functions as an electronic key for remotely arming,
disarming, and performing other panel-specific operations.
The TX+2WAYFOB also features the TX+ Encryption protocol
which provides encrypted wireless communication to select
Interlogix control panels. For all other Interlogix control panels
and receivers that are not TX+ Encryption enabled, the
TX+2WAYFOB also utilizes the standard ITI-319 protocol.
When enrolled into a TX+ Encryption supported panel, this
keyfob also offers 2-way communication functionality
providing acknowledgement at the device via a tri-color LED
that transmissions sent have been received by the panel.
