A Remote Subsystem for monitoring a large number of parameters relating to operating equipment at a remote site is disclosed. A monitoring system having a plurality of local service offices each reporting to a central office and each having a plurality of remote subsystems at remote sites reporting to it is also disclosed. Each remote subsystem reports only a first alarm condition detected for a particular unit of equipment to its local office and reports the unit back in a normal operating condition only after all detected alarm conditions have returned to a non alarm status. In this way, the local and central offices are not inundated with information of little value. Each remote subsystem also monitors conditions that are indicative of impending alarm conditions in order to alert local and central service offices of developing problems in the field. Similarly, each remote system monitors and accumulates miscellaneous data useful for a variety of monitoring purposes. Periodic reports are generated from each remote subsystem to the local ofices and on to the central office.
