Flexibility of this CU allows for optimization of both equipment and costs of operation in both minor and major structures as well as scattered groups of buildings. While working in the network system and when losing connection with a superior unit ABT-CU-11LCD/LT is able to carry out Evacuation scenarios independently thanks to the locally recorded configuration.
If attached to the main communication ring of the system ABT-CU-11 can not only control amplifiers and power supply managers but receive alarm and digital signals and send them to other devices in the system as well. ABT-CU-11LT control unit distributes audio signals to individual zones and supervises the correctness of functioning of individual zones. It also controls the condition of a loudspeaker line and amplifiers.
It detects and signals defects and insets a backup amplifier. This CU is equipped with an ABT-cAudIO-4/12 card offering 4 audio inputs and 12 audio outputs intended for connection of amplifier inputs. ABT-CU-11LT can be equipped also with an LCD colour and touch display that gives a direct access to the managerial function and monitoring of the whole system – in this way we obtain additional configuration called ABT-CU-11LCD.
