or alarm system, connect to appropriate, volt-free or Digital input (5V
max). Volt free input/dry contact: Non polarity sensitive, short circuit =
light on
Digital input: Orange = Digital +5v, Purple = Signal GND
0V = Light on, 3V = Light off
Warning :
When controlling the lamps by a digital input the absolute
maximum voltage on the telemetry line is 5V DC.
Care must be taken that the connection is the correct polarity.
The signal ground must not be connected to the lamp power input.
The illuminator may be damaged if not connected as described
above.
