The alarm provides the relay output (no voltage), and the external power supply is
required when it connects to the alarm device.
 For DC power supply (left diagram), the input voltage must be no more than
30VDC, 1A.
 For AC power supply, the external relay must be used (right diagram) to prevent
damages to the speed dome and avoid risk of electric shock.
