Resideo Dual Path Advanced Modular Communicator LTEM-PXA, AT&T
Two paths. One alarm report.
The Resideo LTEM-PXA is a dual path alarm communicator that reports alarm signals to a monitoring center over 4G LTE and Ethernet, powered straight from the control panel.

An alarm is only as good as its signal path.
If the alarm cannot reach the monitoring center, the panel cannot do its job. A dual path communicator gives alarm reporting more than one way out.
Built for reliable alarm reporting
The LTEM-PXA pairs dual path reporting with simple setup and add-on modules.
