Signal control units MPU-2008/2016/2024/2032 are the central processor of the public address system, allows you to build a public address system of 3,4 and 5 types for 64 zones. With built-in memory, it allows you to record, store and play back alarms and music programmes in MP3, PCM format up to 1 hour long.The unit collects information on the status of all devices connected to the system and, in case of malfunction, displays the information on the display.
The unit monitors loudspeaker lines at user-defined intervals. During commissioning, the impedance of obviously serviceable lines is measured and the values are recorded in the memory of the unit, the control of lines is carried out by comparing the impedance value recorded in the memory of the unit with the impedance of this line at the time of measurement.
If the impedance deviates from the previously recorded in the memory, the device gives a signal of faulty line and displays the cause of the fault.
