The Fire-Lite ES-50XI is an intelligent addressable fire alarm control panel designed to support up to 50 addressable devices in any combination of detectors and modules. It features a single SLC loop compatible with both LiteSpeed and CLIP protocols, along with two Class A/B NAC circuits and built-in programmable relays.

The ES-50XI does not include a pre-installed IPOTS-COM communicator.

The ES-50XI is a direct replacement for the MS-9050UD fire alarm control panel.
