Chamberlain Sentex INFINITY Installation Instructions Manual page 14

INSTALLING A NEW UNIT IN AN EXISTING
MULTI-LINK CHAIN
Once the unit is installed, re-sequence all the units in the chain.
Enter the system's configuration information into the new unit,
(i.e., program access codes, relay activation times, holiday
schedules, etc.).
NOTE: If the new unit does not appear, refer to Baud Rate for
RS-232 Communication.
• If you are using SPS or SPSWin:
• Perform "RECEIVE ALL" from the new unit's memory.
• Copy the system's memory.
• Enter the system's configuration into SPS or SPSWin.
• Send the new configuration to the new unit.
POWER CONNECTIONS
The Infinity system can operate on either AC or DC power.
AC POWER
Connect one end of a two conductor stranded wire cable to TB1
on the main processor board (Figures 6 and 7) and the other end
to the transformer provided with the system. Then plug the
transformer into a 120 VAC outlet.
• Line Loss: If the system and power supply are too far apart,
line loss may result in inadequate voltage being delivered to
the system. Refer to the chart below for wire sizes and
distances.
• Dedicated Power Source: Wire each outlet used by the
Infinity system to its own circuit breaker. This reduces line
noise and minimizes the risk of other equipment interrupting
unit operation.

POWER ON
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 (Figure 6 and Figure 7).
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.

• Dedicated Power Supply: The transformer used by the Infinity
cannot provide power to the door strikes (if used) or the
optional CCTV.
DC POWER
Connect one end of a two conductor stranded wire cable to TB13
(TB1 on E and F rev. boards) on the main processor board
(Figure 6 and Figure 7) and the other end to the power supply.
Then plug the power supply into a 120 VAC outlet. Follow the
same steps for optional CCTV.
• DC Power: must be at least 13.5 Volts.
• DC Input Fuse: The DC input on the Infinity board is not
fused. The installer must wire a fuse between the DC power
supply and the system during installation.
• Line Loss: If system and power supply are too far apart, line
loss may result in inadequate voltage being delivered to the
system. Refer to the chart below for wire sizes and distances.
• Uninterruptible Power Supply: The Infinity will not trickle
charge a battery, so DC power must be supplied by an
uninterruptible power supply.
CCTV (Optional)
AC or DC Power: Connect one end of a 2-conductor stranded
wire cable to TB1 on the main processor board and the other
end to the transformer provided with the system. Then plug
the transformer into a 120 VAC outlet.
NOTE: For line loss refer to the chart below for wire sizes
and distances.

• If the IN LED lights, proper voltage is being provided.
• If the LO LED lights, the voltage is too low. Check the power
connections, wiring, and transformer.
• 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.
