Radio monitoring system operation method for data transmission using trunking network

摘要

The method involves allocating radio detector (1) to a receiver (2) with a transmission part (3) for trunking network. The receivers are supplied permanently with current and are activated. The power supply of the transmission part to the trunking network is only activated if an alarm message or a routine message about the operation state is to be sent. The address allocation for the radio detectors is carried out by binary coding of n-channels and the routine messages are monitored in the central station and displayed only when they fail to come. Preferably, the routine messages are formed by messages of activating and deactivating the alarm system, messages of employment, underpower display and a combination of message of employment and underpower display.
