ABSTRACT:
A transparent secondary information transmission system for a primary information transmission system is disclosed. The system includes at least one local condition monitor for monitoring at least one of a plurality of input conditions such as temperature, light, smoke or the presence of an intruder. The information representing the condition is digitized and processed by the local condition monitor. The digitized signals are then transmitted over the transmission system in such a way that no interference with normal transmission occurs. At the receiving end, the signals are processed to determine from which of the local condition monitors the signals are being received and what the status of the monitored condition is. A determination is then made whether an alarm should be generated. In the preferred embodiment, the primary information transmission system to which the secondary information transmission system is adapted to be coupled is a telephone network.
