摘要： A computer controlled radio activated security and safety system suitable for interrogating a plurality of locations sequentially and for obtaining replies to indicate the condition of the locations and which is completely independent of any external connection between an interrogator location and an interrogatee location for interrogating a plurality of locations sequentially and obtaining replies to indicate the condition of the locations. The system comprises a computer center, at least one main transmitting and receiving station and at least one remote alarm unit which is adapted to monitor a predetermined parameter. The remote alarm unit is also provided with at least one receiver and transmitter, and the computer is adapted to interrogate the alarm unit with a predetermined digital signal and to monitor its reply, the reply being modified by any variation in the parameter.
