The Notifier NFW-50X is an intelligent addressable fire alarm control panel in the FireWarden Series with a pre-installed communicator. It supports up to 50 addressable devices in any combination of intelligent detectors and modules, making it well suited for small-to-medium commercial buildings, schools, retail, and multi-tenant sites.

The panel includes an integral 80-character backlit LCD, a 1,000-event history file, and NFPA 72–compliant automatic detector sensitivity testing. Program databases and firmware can be uploaded or downloaded via the on-board USB port (direct cable or USB flash drive) or over Ethernet using the IPOTS-COM communicator, and the USB port also exports history, walk-test data, current status, and system voltages for diagnostics.

Notification outputs include a terminal block for two Notification Appliance Circuits configurable as Style Y (Class B) or Style Z (Class A). The enclosure measures 20.00" H × 22.5" W × 8.5" D and weighs 26.9 lb. The NFW-50X is a direct replacement for the earlier FireWarden-50 (NFW-50). UL listed for commercial fire alarm control panel use; ships brand-new from authorized Notifier stock.
