Amplifier
3.3.1
SPA
The SPA(Security Power Amplifier) were specifically developed to meet the requirements of EN 60849
for safety installations. Each amplifier module is fitted with its own 220 VAC/24 VDC power supply for
increased system reliability. To avoid handling errors, the volume output is set using the potentiometer
located at the back of the apparatus. In addition to standard protection via fuses, SPA amplifiers also have
electronic and thermal protection to protect them from all potential hazards.
A fan provides forced cooling for the final power shelves and internal parts of the apparatus. It starts up
automatically when the temperature reaches a certain threshold, and stops when it returns to normal
values. Four LEDs display the status of each amplifier: AC or DC power supply, Line Overload and
Temperature overload. Furthermore, a three LEDs VU-Meter indicates the presence and level of audio
signal.
A surveillance circuit continuously monitors the temperature and the presence of AC and DC power
supplies for both amplifiers. In case of a problem, the overload LEDs will be switched ON and the Fault
relay will be activated. The SPA series(SPA 2060, 2120, 2240) can be ordered with optional 115V power
supply.
