Abstract

The system employs a central control (50) located in a vehicle carrying specialised personnel and a number of peripherals (51) each located at a surveillance point, and receiving signals provided by alarm means. The central control (50) has a memory (53) storing the address of each of the peripherals, means for coding these addresses (54) and means for cyclically transmitting them (56). Each peripheral (51) has a receiver (57) for receiving the coded addresses, a memory (61) and a code (62) for coding and storing the alarm signals, and a transmitter (64) for transmitting signals indicating the state of the alarm means. These are received by the central control (50) to release visual or audio signalling means (70, 69) when an alarm signal is received.
