9-1-1 Master Clocks & Accessories

In 1996, NENA (the National Emergency Number Association)published the NENA-04-002 Standard for a PSAP (Public Safety AnsweringPoint) Master Clock. This Standard assures that a Master Clock (builtto this Standard) is capable of interfacing with all necessaryequipment within a PSAP.

With this in mind, ESE designed the ES-911/GPS™, a GPS (GlobalPositioning System) based "NENA" Master Clock. ESE offers several otherMaster Clocks that reference other sources of "legal" time. The ES-181references the USNO (U.S. Naval Observatory) via Modem and the ES-180Areferences the NIST (National Institute of Standards and Technology)via WWV. (Either the ES-181 or ES-180A are capable of meeting the NENAStandard when combined with an ES-223 Time Code Converter).
