4 Operation
The F-Guard-IR3-HD is a triple-IR flame detector that includes a built-in high-definition video
camera module. The video module automatically records video of alarm events and can provide
live video of the detection zone to a screen in the control room.
On power-up, the LED on the front of the detector flashes Yellow indicating the startup routine
has begun. After approximately 30 seconds, if the startup is successful, the LED turns green,
the 0-20mA output goes to 4mA and the fault relay is closed.
Detector configuration settings can be changed as described in section 2.7.
To restart the detector, cycle the power.
Output Signals
The detector has the following output signals:

Current output (0–20mA) with HART ® 7

Relays (Fault, Auxiliary and Alarm)

Modbus RS-485

