Introduction
This publication provides an overview of the features, specifications, and capabilities of the TrueAlert power supplies (TPS). These supplies provide
auxiliary power, a battery charger, and three Signaling Line Circuits (SLC). Each of which provides control and power to the full range of TrueAlert
appliances.
The TrueAlert power supplies are identical to each other with the following exceptions:
• 4100-5120 Domestic (US) version, requires a 120 VAC power source.
• 4100-5121 Canadian version, requires 120 VAC power source and provides battery cutout option. After installing a 4100-5121, refer to
“Enabling Low Battery Cutout Option” in the ES Panel Programmer’s Manual (574-849) for information on enabling this option.
• 4100-5122 International version, uses a 220/240 VAC power source.
If you are wiring Class A circuits, you need to install a 4100-5124 Class A Adapter Card onto the TrueAlert Power Supply before installing the power
supply. Refer to Document # 579-337 for more information.
This product is compatible with the 4100U and 4100ES Fire Alarm Control Panel (FACP).
Note: Verify FACP System Programmer, Executive, and Slave Software compatibility when installing, or replacing system components. Refer to the
Technical Support Information and Downloads website for compatibility information.

Introduction to the TPS
The features of the TrueAlert Power Supply are:
• Three Signaling Line Circuits. The TPS provides uninterruptible power and control to three separate channels of TrueAlert addressable
notification appliances. Each channel is referred to as a Signaling Line Circuit (SLC) and is power limited, power limited is defined in NFPA 70
(National Electric Code). The SLCs can be either Class B (Style 4) or Class A (Style 6). Class A requires the installation of a Class A adapter board.
All SLCs are monitored for short and open circuits.
• 24VDC AUX Power. Provides up to 2 A of 24 VDC auxiliary power for use by the option cards.
• Internal Battery Charger. Charges up to 50 Ah (ULC-S527) or 110 Ah (UL-864 Listing) batteries connected to the power supply. The charger
circuitry provides status monitoring of battery connection, input power, and Earth faults.
Figure 1: Overview of TPS
Additional Features
• Full TrueAlert Operation. TrueAlert addressable notification appliances are individually addressed and receive power, supervision, and
control signals over the SLC. Horns sound with selectable high or low output, using a temporal, march time (60 or 120 beats per minute), or
continuous pattern. Horns are controlled separately from visible appliances installed on the same two-wire circuit. (Combination speaker/
strobe TrueAlert appliances receive audible control from separate audio circuit wiring.)
• Extensive Diagnostic Capabilities. LEDs on the TPS flash codes that identify the nature of trouble conditions. The TPS also monitors for
short and open circuits and positive and negative Earth fault status.
• Depleted Battery Cutout (Canadian Version Only). When AC Power fails, the Depleted Battery Cutout feature disconnects a battery from
the panel when its voltage is approximately 18 VDC.
• Visual Synchronization. A maximum of 46 MultiCandela addressable visuals may be synchronized per SLC. All SLCs are synchronized across
a TPS. All TPSs are synchronized across the FACP.

Configuring the TPS
Setting Earth Fault Enable/Disable Jumper
The Earth Fault Enable/Disable jumper allows you to enable or disable positive and negative Earth Fault detection.
Place the jumper block on Pins 1 and 2 to enable Earth fault detection. Place the jumper block on Pins 2 and 3 to disable Earth fault detection. See
below.
Figure 3: Earth fault enable/disable jumper
Note:
When one or more TPS unit resides in a system sharing a common "0V" with any other type power supply (SPS/RPS/XPS), jumper only one of the TPS
units to enable Earth Fault Detection. All other power supplies must be jumpered to disable Earth Fault Detection. Ensure that the Slave Exec firmware,
later than Revision 1.04, is loaded on this TPS.
Setting Address Switch
The TPS device address is set via DIP switch SW1, which is a bank of eight switches. From left to right (see Figure 4), these switches are designated as
SW1-1 through SW1-8. The function of these switches is as follows:
SW1-1. This switch sets the baud rate for the internal FACP communications line running between the card and the FACP CPU. Set this switch to ON.
SW1-2 through SW1-8. These switches set the card's address within the FACP.
Note:

batteries, and distributes power to each bay in the cabinet.
Power Distribution Module Connections
The Power Distribution Module (PDM) connects to every power supply in each back box. Connect the 734-012 Harness from the top connector
on the PDM to the TPS.
1. Wire 120 VAC to the PDM, keeping AC wires at least one inch away from all other wires. AC power must be kept to the right side of the cabinet, in
the non-power-limited area.
2. Connect batteries to P5 on the PDM using Harness 734-015.
3. Connect the PDM to the TPS using Harness 734-012.
• Connect the separate Red and Black wires (with Yellow female terminations) to Plugs P5 (Black) and P4 (Red) on the TPS.
• Connect the White and Black wires, which terminate together in a White snap-on connector, to the bulkhead connector at the bottom of the

General Wiring Guidelines
• Use only copper conductors for all wiring applications. All equipment must be installed in accordance with the manufacturer's
recommendations and the specifications and standards of the authority having jurisdiction (AHJ). The installation of all wiring, cable, and
equipment must be in accordance with NFPA 70 and the National Electrical Code (NEC), specifically Article 760 (Fire Alarm Systems), Article 800
(Communications Circuits).
• If applicable, the installation must be in accordance with the Canadian Building Code, and any provincial and/or local requirements.
• Each TrueAlert channel is limited to 0.60uF maximum capacitance. This includes conductor to conductor and conductor to shield capacitance
(if shield wire is used).
• TPS wiring must use ferrite beads in order to comply with the RF Immunity test specified in UL864.
• If shielded wire is used, the following must be observed.
- Metallic continuity of the shield must be maintained and insulated throughout the entire length of the cable.
- The entire length of the cable must have a resistance greater than 1 Mega ohm to Earth.
• Underground wiring must be free of all water.
• Wiring other than that connected to elevator cabs must not be run in elevator shafts (reference NFPA 70, Article 620).
• Wiring in ducts, plenums, and other air handling spaces must be installed in accordance with NFPA 70, Article 300.
• Splicing is permitted in accordance with NFPA 70. All junctions must be insulated as soundly as the original jacket. Continuity of shields (where
used) must be maintained.
• A system ground must be provided for Earth detection and lightning protection devices. This connection shall be made to an approved,
dedicated Earth connection, per NFPA 70, Article 250.
• Only system wiring can be run in the same conduit.
• Field wiring circuits shall not leave the building of origin unless all of the following conditions are met.
- Circuits are protected from lightning by utilization of either the Model 2081-9044 or the Model 2081-9028 listed isolated loop circuit
protectors.
- One isolated loop circuit protector is inserted into the circuit where the wiring leaves the building. A second isolated loop circuit protector is
inserted into the circuit where the wiring enters the next building.
- Underground wiring circuits are run in a parallel wiring trough separate from any commercial power distribution wiring.
- Overhead circuit wiring is run in parallel with relation to the commercial power distribution wiring. Overhead circuit wiring is separated from
the commercial power distribution wiring by a minimum distance equal to the maximum span between two adjacent poles of either the
system's circuit or the commercial power distribution circuit, or 100 feet (30 m), whichever is greater. Outside plant wiring is limited to one
contiguous property and the total wire length may not exceed 3,270 feet (997 m).
Power-Limited/Non-Power Limited Wiring Guidelines
Adhere to these guidelines when wiring power limited and non-power limited wiring within the FACP.
• Non-power limited field wiring (AC power, batteries) must be installed and routed in the shaded areas shown in the figure below.
• Power-limited field wiring must be installed and routed in the non-shaded areas shown in the figure below.
• Excess slack should be kept to a minimum inside the back box enclosure. The wiring should be neatly dressed and bundled together using the
wire ties provided with the equipment. Anchor power-limited wiring to tie points, as shown in the figure below.
• Tie the wiring located between bays to the internal wiring troughs, if applicable.
• When powering remote units or switching power through relay contacts, power for these circuits must be provided by a power-limited power
supply that is UL listed for fire-protective signaling use. A UL listed EOL relay must be used to supervise the auxiliary power circuit.
Important: If the TPS is powered up with zero devices connected, the TPS indicates channel failure for those channels that are programmed to
support devices. The TPS does not sense devices as they are connected when the TPS has been powered up with zero devices connected. After at
least one valid device is connected, the unit must be reset by toggling the DIP Switch SW1-1 OFF and then ON. The TPS then communicates with
devices as they are added.

Wiring Class A Circuits
Class A Guidelines
• Class A wiring requires purchase of 4100-5124 Class A Adapter Module
• Only TrueAlert appliances and accessories ("devices") are allowed on these signaling line circuit (SLC) channels. Refer to Table 4 for a list of
compatible TrueAlert devices and to the TrueAlert device installation instructions for connection details.
• Maximum of 63 devices or 75 unit loads per channel. Refer to section "Compatible TrueAlert Devices" for unit load ratings of TrueAlert
compatible devices. The maximum number of visuals that can be synchronized on one circuit is 43 for fixed candela and 46 for multi-candela
devices. The maximum resistance between any two visuals is 30 Ohms.
• All wiring is supervised and power limited.
• All wiring to be twisted pair. Wire must be minimum of 18 AWG (0.82 mm²) and maximum 12 AWG (3.31 mm²). If shielded pair is used, then the
cable shield drain wire must be attached back to the (–) Terminal at both Class A and Class B ends of this circuit. Only one wire per terminal
position.
• Maximum alarm current is 3.0 A per SLC channel. Use alarm current for lowest rated appliance nameplate voltage. Total alarm current for all 3
channels plus all current draw from AUX power and option cards must not exceed 9 A.
• Supervisory current is 0.20 mA per unit load.
• Maximum length of all wire segments added together is 10,000 feet (3,048 m) per channel. Maximum wire length from panel to any device is
2,500 feet (762 m).
• T-Tapping is NOT allowed. Maximum wire distance from panel to appliance farthest from the panel is the smaller of the values obtained from
Table 4 and Table 5. Add the alarm loads of all the devices on an SLC wire loop and apply to Table 4.
• Voltage rating is 24 VDC nominal, 2 V peak-to-peak ripple, maximum.
• Overvoltage suppressors are required when wiring leaves the building. Use Simplex Model 2081-9028 for wire distances of up to 1,000 feet
(305 m). Use Simplex Model 2081-9044 for long wire distances and light alarm loads. Note that the 6 Ohm line resistance of Simplex Model
2081-9044 will decrease the distances given in Table 4. Maximum two suppressors between any device and SLC channel terminals (A or B). See
General Wiring Guidelines for information regarding wiring that leaves a building.

Class B Wiring Diagram (No Isolators)
For Class B wiring with no isolators, T-Tapping is allowed. SLC wiring may be split multiple times to form SLC wiring branches. Maximum wire distance
of each of these SLC branches from the panel to any device is the smaller of the values obtained from Table 6 and Table 7. Add the alarm loads of all
of the devices on an SLC branch and apply to Table 6. Add the unit loads (see Table 3) of all the devices on an SLC branch and apply it to Table 7. Use
of Table 6 and Table 7 requires all SLC wire branches join within 10 feet (3 m) of the panel. T-tap wire stubs are allowed on the SLC wire branches, but
each tap must be less than 100 feet (30 m).
Note:
Each B+ and B- terminal is rated for 2 identical wires. This allows up to 4 Class B T-Tap circuits directly from each Terminal Block. See Figure 10.

Troubleshooting
System Trouble Indicators (LEDs A through E)
The system trouble indicators consist of a bank of five yellow LEDS (refer back to Figure 1 for their location on the TPS). These LEDs are used to signal
various trouble conditions on the TPS and its SLCs. Only one trouble at a time is shown. You can step through all of the troubles present on the TPS or
its SLCs using the Trouble Scroll Pushbutton. This pushbutton is shown in Figure 1 and is located just to the right of LEDs A through E.
Note:
• Any trouble indication that applies to a specific SLC channel has the corresponding LED (CH1 through CH3) for that channel lit.
• The Trouble Scroll Pushbutton allows an operator to scroll through multiple troubles.
