Expansion Power Supply Modules

This publication describes the installation procedure for the following:

• 4100-5101 Expansion Power Supply (XPS), 120 VAC, 60 Hz

• 4100-5102 XPS, 220 VAC/230 VAC/240 VAC 50 Hz/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 three 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

in accordance with 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 VDC circuits, or special application circuits. When used as generic 24

VDC regulated circuits, only 4 Amps of current is available across the three 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 three circuits and only the compatible appliances listed in Table 5 may be connect to

these circuits. The SPS/RPS can synchronize compatible appliances across all three 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 mis-wiring 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 ohm minimum.

The 4100-5103 model is 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.

Do you have a question about the Simplex XPS and is the answer not in the manual?

The Simplex XPS (Expansion Power Supply) and XNAC (Expansion NAC Module) are components designed for use with 4100U and 4100ES fire alarm control units (FACUs). These modules provide additional power and notification appliance circuits (NACs) to expand the capabilities of a fire alarm system.

Function Description:

The XPS serves as an Expansion Power Supply, distributing added card power and signal power. Signal power is localized to the bay where the XPS is installed, while card power sourcing is determined by jumpers P4 and P5 on the Power Distribution Interface (PDI). The XPS includes three NACs and can be expanded to six NACs with the addition of a 4100-5115 XNAC module. These NACs are power-limited in accordance with UL 864 and support non-addressable TrueAlert and conventional reverse-polarity operation.

The NACs on these modules can be configured as either regulated 24 VDC circuits or special application circuits. When used as generic 24 VDC regulated circuits, a maximum of 4 Amps of current is available across the three circuits for any 24 VDC appliance. For special application NACs, the full 9 Amps of current is available across the three circuits, supporting compatible appliances listed in the manual. The SPS/RPS can synchronize compatible appliances across all three circuits when configured as special application NACs.

The XPS has a total capacity of 9 Amps. Each NAC is rated at 3 Amps and can also be configured as an auxiliary power point, in which case it is rated at 2 Amps. The total 24 VDC load, encompassing NACs (on XPS or XNAC), auxiliary power, card power, and signal power for modules in the same bay, must not exceed 9 Amps. If NACs are used as auxiliary outputs, they must be configured as such in the Panel Programmer, with additional programming potentially required for dedicated auxiliary outputs.

NACs are continuously monitored for short and open circuits. In the event of a short circuit, the affected NAC will not be energized. A NAC mis-wiring test, which checks for shorted NACs, can be initiated from the operator interface. AC power and battery backup for the XPS are provided through a connection to the PDM. Earth fault detection on XPS wiring is performed by the SPS, RPS, or XBC, with a minimum detection resistance of 10k ohms. The 4100-5103 model, specifically for jurisdictions like Canada, requires the unit to power down upon depleted battery conditions until AC power is restored, and the system must be programmed for depleted battery cutout for each power supply.

Usage Features:

Mounting: The XPS is typically mounted in the rightmost top and bottom positions of the PDI in a 4100 expansion cabinet. Installation involves inserting tabs into slots, pushing the assembly against the back of the expansion bay, connecting to the PDI, and securing with a #6 torx screw. For the 4100-2301 expansion bay, the front door should be removed to prevent damage.
Configuration (DIP Switch SW1):
- SW1-1: Sets the baud rate for internal 4100 communications. Must be set to ON for communication.
- SW1-2 through SW1-8: Set the card's address within the 4100 FACU, as assigned by the Panel Programmer.
Internal Wiring: The XPS receives power from the Power Distribution Module (PDM) or power distribution terminal block, which in turn draws power from AC mains and backup batteries. Detailed instructions are provided for connecting the PDM to each bay, including routing AC power wires through a ferrite bead and connecting batteries.
4100-2301 Expansion Bay Wiring: Specific instructions are provided for DC wiring (connecting the battery block to the XPS using harness 734-050) and AC wiring (connecting white and black wires from 120 V and NEUT terminal blocks to the XPS assembly using harness 734-049). AC wires must be kept at least 1 inch away from other wires and within the non-power-limited area.
NAC Wiring Styles:
- Class A Wiring: Provides a circuit path for the XPS in case of a single open circuit. Requires two wires routed from the XPS to each appliance and back again to the XPS. The manual includes a table for calculating maximum distances based on current and wire gauge.
- Class B Wiring: The manual includes a table for calculating maximum distances based on current and wire gauge.
Auxiliary Power Wiring: The XPS can power auxiliary appliances via a dedicated auxiliary power tap (TB2) or an unused NAC (if configured as an auxiliary power point). All auxiliary power taps are rated at 2 A, with a total available auxiliary power current of 5 A. The overall total current available is 9 A, from which current used by card power and auxiliary 24 VDC must be deducted.
XNAC Installation: The 4100-5115 XNAC module provides three additional NACs and plugs onto the XPS. Installation involves inserting plastic and metal standoffs, plugging J1 on the XNAC into P3 on the XPS, securing with screws, and connecting the XNAC's signal power harness to P1 on the XPS. The XNAC uses the same wiring rules as TB1 on the XPS but cannot be used for auxiliary power.
Compatible Appliances: Detailed tables list Cooper Wheelock and other NAC-compatible notification appliances and accessories, including synchronizing horn strobes, synchronizing strobes, synchronizing horns, coded audible appliances, and non-synchronizing appliances.
Ferrite Beads: For CE compliant systems, ferrite beads are required. Wires should be looped once through the ferrite beads as shown in the figures. Kit 4100-5129 includes three ferrite beads.

Maintenance Features:

Troubleshooting: The manual provides a troubleshooting section detailing common messages that may appear on the 4100 display and their possible causes:
- No Communications with Master: Check 0 V connection to PDM and fuse in the black battery lead.
- AC Power Loss: Indicates voltage below acceptable levels, possibly due to wiring issues, PDM problems, or dedicated AC power.
- Battery Not Connected/Battery Depleted: Reports battery status (e.g., low battery, blown fuse, not connected).
- Expansion NAC Card Configuration Mismatch: Occurs if an XNAC card is missing when configured or if an un-configured XNAC card is physically installed.
- NAC Miswired Trouble: Detects NAC-to-NAC shorts, indicating which NACs are affected. Up to 4 mis-wiring faults can be displayed.
Additional Power to Motherboards: The XPS can supply additional 24 V to motherboards in the system, with a diagram illustrating the connection.
