Annunciator Controller (UUO and UUO-RGB)
Annunciator controller (UUO, UUO-RGB)
The external annunciator controller UUO (UUO-RGB) provides possibility to connect the annunciator to the descrete outputs (for example, relays) of fire alarm panels or controllers. Use of the annunciator EKRAN-INFO or EKRAN-INFO-RGB together with the UUO (UUO-RGB) allows replacing of up to four separate annunciators. The UUO (UUO-RGB) is located outside the explosive area. The controller comes in two modifications: in airtight casing (IP54) and in a casing designed for DIN rail mount, sizes 35 mm and 32 mm.
Communication with the annunciator is carried out via the RS-485 interface with galvanic separation unit and the communication line controller. The maximum lenght of the communication line is 1 km. In case communication is lost between the annunciator and the UUO (UUO-RGB), the latter generates an alarm signal on control inputs; this signal is recognized by the controller (the control console).
Text messages are displayed in turn, depending on signals of the control inputs and on input priority. An input with a bigger number will has a higher priority. One message only is displayed at any given moment; a message of the respective control input is displayed last, taking into consideration its priority.
