External Door Lock Power

J43 provides the external door lock power (see Figure 23). Connect the line from the power supply
to J43 (see Figure 24). Power can be from an i
ndependent power supply or can be daisy-chained
from the controller/cabinet power supply (Section 3.7 on page 20). Power is provided to the relays
through the lock relay common line.

NOTE: When providing power for door lock relays, Keri strongly recommends using two separate
power supplies. This isolates controller power from the transients that can be created as the door
relays kick on and off.
