Power Supply
Power Supply w/Line Conditioner
• The power supply is the heart of the Millenium System. It
can support between 15 DCD boards (power for locks and
other devices provided by local power supplies.
• In addition to providing board power, the power supply has
an integrated line conditioner which generates the biasing
voltage necessary for RS-485 communications and to filter
out any noise or interference on the communications
cabling.

IMPORTANT
In a Standard Millenium System, one power supply
with line conditioner must be used.
F3
For a Millenium Windows System, each SCU must
have at least one power supply on that branch that
employs a Line Conditioner.
In either system, the -TXR and the +TXR terminals are
not used for the additionally required power supplies.
Only the Signal Ground terminal is used to bond the
power supplies together.

Power Supply Tech Tips
• AC must be wired by Qualified Electrician.
• Earth Ground to Terminal 12.
–
–
–
–
–
Use Solid Core cable, AWG #10 or better.
Less than 50 ft to ground source is ideal.
Use 6” radius bends on the cable. No sharp 90º corners.
Use mechanical ground clamp to attach wire to ground source.
Use CWP, UFER ground, or some other verified and approved ground source.
No Gas or Fire Sprinkler Pipe.
• Create a monolithic shield for the signal ground.
– Ground shielded cable on one end only. Tie down the shield to terminal 12.
– The -TXR and +TXR terminals are not used on additional power supplies
within the same SCU branch. Only the shield and a common negative is
connected between power supplies to establish the bonded signal ground.

Power Supply Tech Tips
• The Power Supply can only be loaded to a maximum of
80% of its current rating.
– Maximum rating is 5 AMPs or 5000 mA. Eighty percent loaded is 4 AMPs or
4000 mA.
• Replace fuses with like rated fuses.
• Replace lead acid batteries every 3-5 years.
• The Unican part number for the power supply is:
120 VAC, 60 Hz PS1-100212-001.
240 VAC, 50 Hz PS1-100213-001.
• Power Supply part number includes batteries and a locking
enclosure.
