4.5 Remote Alarm Device and Customer Input Events

Remote alarm devices are various sensors and detectors outside the cooling unit that provide information about conditions
and situations that may affect operation. Remote alarm devices (RAD) include smoke detectors, filter condition, valve status.
Included in the RADs option are up to four customer input events depending on cooling unit configuration. In some cases,
