Novanex offers both Power-over-Ethernet (PoE) or 24 volt powered high visibility LED signs for displaying critical messaging. The OAX2 LED series also functions as an NTP synchronized clock if desired. Available with or without flashing light and alert tone. The OAX2-NEMA model has been tested to NEMA4x / IP66 standards for water and dust ingress protection, making it ideal for environments where high noise levels make emergency communication difficult.
