Mounting the apC/8X
Connecting the Advanced Power System (apS)
The apS is an optional 1 power supply unit that provides uninterrupted power
backup for the apC/8X. It has knockouts that line up directly to those on the
apC/8X, and compatible terminal blocks and cable harnesses that keep wiring
to a minimum (see Figure 3.5).

Figure 3.5: apS Connection to apC/8X
Note:
Battery cables are not power limited and should be isolated from
all other cabling by a minimum of 1/4”. Route the battery cables
away from all other wires.
The apS provides two relay outputs for connecting inputs to the apC/8X.
• One relay is connected to the MAIN FAIL input on the apC/8X and
indicates when AC power is lost.
• The second output is connected to the MAIN BATT input on the apC/8X
and indicates low battery voltage or impending loss of backup power.
LEDs on the cabinet door of the apS indicate AC power loss and the state of
the battery charge as relative battery voltage level.
The apS low battery fault and power fault outputs can be looped together and
attached to the apS fail on the apC/8X or tied to separate monitor points on
the apC/8X.
1. The apS is optional only in UL294 access control applications. The apS, or some other
UL-Listed Class 2 power-limited UL603 or UL294 power source (with the necessary
standby capability) is required for UL1076 applications.
