Step 2. Mounting Illuminator

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
