Figure A.9.1 Alarm Out Connections
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.
