Ajax EN54 Fire Detection Rex White

• EN54 Fire ReX Jeweller expands the range of a wireless network and delivers a stable connection for EN54 Line devices across a large or complex facility. The range extender connects to the control and indicating equipment (CIE) wirelessly or via Ethernet, delivering reliable communication through steel and concrete. Up to 5 range extenders can operate within one Ajax system, and each supports any combination of devices for fire safety, automation, and intrusion protection. Mix devices within the CIE's limit to leverage the benefits of the integrated system, including visual verification of alarms.
