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.
