SYSTEM POWER
Connect 2 conductor cable (for wire size, see Table 1
below) from TB4 at the Mini-Key unit to the 12VAC, 20
VA transformer supplied by Sentex (or 13.5 VDC power
supply that you provide).
Do not connect the power to the system until all
connections have been made to the system.
Please Note: If you are using a DC power supply, the
Mini-Key system will not trickle charge a battery, so the
DC power must be supplied by an uninterruptible power
supply (UPS).
