Compared with the smallest broadcasting system, it mainly adds the zone link, timing control link, alarm link and the interface with the fire center. Normally, the system runs under the management of a programmable timer PA-2089 (the power of the relevant links is turned on and off regularly according to a pre-programmed program), and the clock signal of the clock at the rest time is played on time. When the fire center sends an alarm signal to the system, the relevant links are forcibly started through the linked interface (regardless of the state of the program); at the same time, all the zones are forced into the emergency broadcast, regardless of whether it is closed.
Secondly, in the following figure, the power amplifier and preamplifier are also separated, which makes the system combination and control more convenient. In addition, a -monitor-listener-device is also configured to monitor the operation of the system..
