Step 2. Mounting Illuminator
VARIO2 is delivered as standard with bracket at the bottom of the unit.
This can be moved to the top of the unit if required. See page 18 for
optional brackets
Step 4. Telemetry Input (Orange & Purple)
As default the telemetry input will be wired together so that the unit turns
on/off automatically via the photocell. If required to be activated by PIR
or alarm system, connect to appropriate, volt-free or TTL input. Volt free
input/dry contact: Non polarity sensitive, short circuit = light on
TTL input: Orange = TTL +ve, Purple = TTL –ve (GND) 0V = Light on, 3V =
Light off
