MAIN PROCESSOR BOARD
The Infinity main processor board has a power monitor that indicates if proper voltage is available.
It has two red LEDs labeled HI and LO, one green LED labeled IN, and a MONITOR CLEAR
button, all located in the upper right corner of the main processor board (see Figure 3 or Figure 4).
If input power is not in the acceptable range, the HI or LO LEDs light and remain lit until the
MONITOR CLEAR button is pressed. This allows continuous power monitoring and captures any
transients.
Check voltage using the power monitor as follows:
1. Apply power to the board. The IN and LO LEDs will light.
2. Press the MONITOR CLEAR button located next to the LEDs.
o If the IN LED lights, proper voltage is being provided.
o If the LO LED lights, the voltage is too low. Check the power connections, wiring, and
transformer.
o If the HI LED lights, the voltage is too high. Check the power connections, wiring, and
transformer.
CCTV POWER SUPPLY BOARD
Power comes on when the transformer or power supply is plugged in. There are no power
indicators on the board.
