Step 2. Mounting Illuminator
All IR850, IR940 & WLED illuminators are delivered as standard with the bracket at
the bottom of the unit. This can be moved to the top of the unit if required.
Step 3. Connect to low voltage power supply and input 12-24 AC/DC
The illuminator is operational with 12V to 24V DC or AC voltage. When using DC
power, the Red wire must be connected to the positive side of the power supply
and the black wire to negative. When using AC power, there is no specific polarity.
Step 4. Telemetry Input plus ‘Dim’ function (Orange & Purple) OPTIONAL
The telemetry input can be used to control the lamp and dim function from an
external source. As a default, the telemetry inputs are wired together for standard
photocell controlled on/off operation.
If required to be activated by an external source, connect as an appropriate volt-free
or TTL input.
Volt free input/dry contact: Non polarity sensitive: Short circuit = light on
TTL input: Orange = TTL +, Purple = TTL (GND)
0V = Light on, 3V = Light off
Step 5. Photocell following output (White & Yellow) OPTIONAL
The Photocell following output can be used to manually control the day/night
operation of a camera. The volt free output is open when the photocell senses
daytime ambient light levels, and is closed when it senses nighttime ambient light
levels.
