Once powered up, the UV/IRS-H2 will begin a 90 second start up routine.
During this time, the current output will be 3 mA. The UV and IR source
lights and the Green power LED will be on for the 90 seconds. Once the start
up procedure has finished, and no faults are present, the detector will begin
normal operation (current output 4 mA and Green LED will remain on).
