This publication describes the installation procedure for the following:
4100-5101 Expansion Power Supply (XPS), 120 VAC, 60 Hz
4100-5102 XPS, 220/230/240 VAC 50/60 Hz
4100-5103 XPS, 120 VAC, 60 Hz, with battery disconnect (Canada)
4100-5115 Expansion NAC Module (XNAC)
The XPS distributes added card power and signal power via the PDI. Signal power is available only in
the bay in which the XPS is located. The source of card power is selected by jumpers P4 & P5 on the
PDI.
The XPS includes 3 NACs, and may be expanded to 6 NACs with the 4100-5115. NACs are wired as
Class B or Class A. All circuits are power limited per UL 864. The NACs support
non-addressable TrueAlert and conventional reverse-polarity operation.
The Notification Appliance Circuits on these modules can be used as regulated 24 DC circuits, or
special application circuits. When used as generic 24 VDC regulated circuits, only 4 Amps of current
is available across the 3 circuits, and any 24 VDC appliance may be attached. When used as special
applications NACs, the full 9 Amps of current is available at the 3 circuits and only the compatible
appliances listed on page 27 may be connect to these circuits. The SPS/RPS can synchronize
compatible appliances across all 3 circuits when those circuits are used as special applications NACs.
The XPS has a 9 A capacity. Each NAC is rated at 3 A. A NAC can also be configured as an auxiliary
power point, in which case it is rated at 2 A. The total load at 24 VDC must be no more than 9 A. The
total load includes NACs (on the XPS or the XNAC Module), auxiliary power, card power, and signal
power used by modules plugged into the same bay.
Note:
If NACs are to be used as auxiliary outputs, they must be configured as such in the
Panel Programmer. Programming may also be required for dedicated auxiliary
outputs; refer to the
ES Panel Programmer’s Manual
(574-849).
NACs are monitored for short and open circuits. If a short circuit occurs, the affected NAC will not be
energized.
A NAC miswiring test, which checks for NACs that are shorted together, can be initiated on command
from the operator interface.
AC power and battery backup are provided to the XPS through a connection to the PDM.
Detection of an earth fault on XPS wiring is performed by the SPS, RPS or XBC. Detection is 10k
ohms minimum.
The model 4100-5103 are required in jurisdictions, such as Canada, where depleted battery conditions
are required, by local code, to result in power-down of the unit until AC power is restored. The system
must also be programmed for depleted battery cutout, for each power supply.
