The No Loss 2400 temperature surveillance system (NL2400) is the successor to the 1400 system. Features of the NL2400 include solid-state temperature sensors; temperature displays, which show the highest temperature of four sensors in each zone; solid-state relays; break/short indicator LEDs to indicate a failure in monitoring one or more sections of a zone; an upgradeable Ethernet connection; and an array of LEDs located at the bottom of the master control panel for status readability. This system monitors itself to ensure an alert for either a system failure or a refrigeration failure, states the manufacturer.
