CONTROL UNIT CUE Rev. A MC Date: 030224
FUNCTION
1. Power Supply Unit with battery backup.
The control unit is supplied with AC-voltage from the mains which is transformed to
the required voltages for operating the different systems and for charging the battery.
If the main supply drops out, the control unit will automatically switch over to
battery back-up, thereby maintaining the full functionality of the central unit. When
the main switch is re-established, the control unit will automatically return to normal
AC operation, and the battery will be recharged.
2. Monitoring.
The control unit checks all the connected components with regard to electrical
operation and the internal function of hardware and software. In the case when a
fault alarm is activated the operator receives a message on the LCD-display
clarifying the type of fault.
3. Control system with pre-programmed functions..
For any detector indication or any other input signal, programmed procedures will
immediately take place. These procedures can vary depending on different factors
for example energy level, number of glows or sparks, indications from several
detectors or other input signals.
4. Electronic log-book
The control unit stores events and alarms in the electronic memory, which can be
recalled by the operator on demand.
