BV225 Installation Manual issue 3

Over temperature protection is provided using sensors attached 
to the output stage heat sink. Should the temperature exceed 90 
Degrees Celsius the input signal to the relevant amplifier will be 
attenuated to a safe level and the “Overload” LED will be 
illuminated.

If the system is under surveillance it will cause the surveillance 
detector to indicate a fault condition due to the gain reduction.
