Installing A New Unit In An Existing Multi-Link Chain; Power Connections - Chamberlain SENTEX Infinity Series Installation Instructions Manual

E. INSTALLING A NEW UNIT IN AN EXISTING MULTI-LINK CHAIN
1. Once the unit is installed, resequence all the units in the chain.
2. Enter the system's configuration information into the new unit, (i.e., program access codes,
relay activation times, holiday schedules, etc.).
3. If you are using SPS or SPSWin:
A. Perform Receive All from the new unit's memory.
B. Copy the system's memory.
C. Enter the system's configuration into SPS or SPSWin.
D. Send the new configuration to the new unit.
F. 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 TB 1 on the main processor board
(see Figure 3 or Figure 4) and the other end to the transformer provided with the system. Then
plug the transformer into a 120 VAC outlet.
NOTES:
1. 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.
2. Dedicated Power Source: Wire each outlet used by an Infinity to its own circuit breaker. This
reduces line noise and minimizes the risk of other equipment interrupting unit operation.
3. 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 TB 13 (TB1 on E and F rev. boards)
on the main processor board (see Figure 3 or Figure 4) 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.
NOTES:
1. DC Power: must be at least 13.5 Volts.
2. 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.
3. 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.
4. UPS: The Infinity will not trickle charge a battery, so DC power must be supplied by an
uninterruptible power supply.
