1.5 Board Layout

Figure 1.1 illustrates the ACPS-2406 board layout, showing terminal blocks (TB1-TB8), DIP switches (SW2, SW3), rotary switch (SW1), jumpers (JP2 for ground fault disable), fuse (F2), LEDs, and connectors for AC power, SLC, UZC, outputs, and batteries. It also indicates the location of the snap-on cover for TB1 and the location of LEDs.

1.6 LED Indicators

There are 16 LEDs indicating various conditions and troubles. Key indicators include:

• GND FLT (Yellow): Indicates ground fault on NAC, battery, or 24-volt output.
• NAC Activated (Green): Illuminates when a specific NAC is activated.
• MONITOR (Green): Blinks during normal polling; off during monitor trouble.
• NAC 1-4 (Green): Steady for communication, blinks for polling.
• TRBL (Yellow): Indicates troubles like brownout, +38V supervision, invalid address, or DIP mismatch. Specific blink patterns denote the trouble type.
• BAT/CHG (Yellow): Indicates battery or charger trouble.
• UCFAILURE (Yellow): Indicates microcontroller failure.
• AC (Green): Indicates AC power is present.
• SLCRXA/SLCTXA (Green): Indicate data transmission on the SLC.

Section 2: Installation

❗ WARNING: High Voltages Present. Exercise extreme caution. Turn off all power sources before servicing. Ensure proper grounding.

2.1 In a CAB-3 Series Cabinet

The ACPS-2406 mounts in the lower left or lower right of a CAB-3 Series enclosure, or in CHS-6 or CHS-PS chassis. Mounting involves fastening the unit to the chassis or backbox using hex nuts or screws as shown in Figure 2.1.

2.2 In a BB-25 Cabinet

The ACPS-2406 mounts on the left side of a BB-25 cabinet. Batteries fit on the right side. Fasten the unit to the backbox with screws as shown in Figure 2.2.

2.3 In a CAB-PS1 Cabinet

The ACPS-2406 mounts in a CAB-PS1 cabinet, with batteries in the bottom. Fasten the chassis to the top right studs with hex nuts as shown in Figure 2.3.

2.4 Wiring

Terminal block and pin connections are shown in Figure 1.1. Power-limited and nonpower-limited wiring must be separated by at least 0.25 in. (6.4 mm) and enter through different knockouts. Figures 2.4, 2.5, and 2.6 show wiring examples for BB-25, CAB-3, and CAB-PS1 cabinets, respectively. TB1 is for AC primary power (nonpower-limited and supervised). TB2 is for nonpower-limited and supervised connections. Output circuits (TB4, TB5, TB6) are power-limited and supervised, except for UZC connections on TB6. TB8 is for SLC wiring. J1 provides auxiliary power.

Section 3: Configuring the ACPS-2406

3.1 DIP Switch Configuration

Programming is done using DIP switches SW2 and SW3. SW3 controls output modes, AC Loss/Delay, Canadian Trouble Reporting, and Dual Stage. SW2 controls output options, Signal Silence, strobe synchronization, and battery charger settings. Figure 3.1 illustrates how to set the DIP switches (OFF/ON). Settings should only be changed when the unit is powered down.

3.2 Addressing

The ACPS-2406 consumes 5, 6, 8, 9, 12, or 13 SLC addresses depending on DIP switch settings. The installer must allocate sequential SLC addresses and set the base address using the rotary switch (SW1) and jumper (JP6). The base address determines the start of the address block, which can end in zero or five. The lowest base address is 05. Tables 3.2 through 3.7 detail address consumption based on DIP switch settings.

3.3 Panel Programming Requirements

Addresses must be programmed into the FACP in numerical sequence. Table 3.8 lists FACP address assignments for ACPS-2406 outputs and functions. Software Type ID codes (Tables 3.9 and 3.10) are required for programming points at the FACP.

Dual Stage Alert/Evacuation

This mode, available for Canada only, allows output circuits to operate in two stages: alert (20 pulses/min) or evacuation (NFPA Temporal Pattern). It is selected by setting SW3.7 ON and SW3.8 OFF, with output circuits set to coded NAC. In Dual Stage, each output circuit uses two control addresses. Figure 3.3 illustrates the control logic and sequence of operations.

Section 4: Applications

4.1 NAC Outputs

The ACPS-2406 provides four NAC outputs (TB4, TB5, TB6) that can be configured for coded or non-coded operation. Figure 4.1 shows the four NAC outputs. An end-of-line resistor (ELR-2.2K) is used for Style Y (Class B) NACs. ELRs should not be used for Style Z (Class A) wiring.

4.2 General Purpose Power

The unit can supply general purpose power. Figure 4.2 shows the connections. These outputs are power-limited and non-supervised; an end-of-line relay is recommended for supervision.

4.3 Style B (Class B) Initiating Device Circuit

Figure 4.3 illustrates the wiring for a Style B Initiating Device Circuit (IDC) using detectors, SLC connections, an end-of-line resistor, and a power supervision relay.

4.4 Synchronization

The ACPS-2406 supports synchronization for SpectrAlert Series, Gentex, and Wheelock strobes and horns when configured with DIP switches SW2.6 and 2.7. Synchronization is also possible for bells and horns using a UZC-256 if the NAC output is coded. Note that strobes cannot be used on coded outputs, and SpectrAlert devices cannot be synchronized with a UZC-256 or coded output. Figures 4.4, 4.5, and 4.6 show wiring examples for supervised master/slave synchronization, UZC-256 synchronization, and supervised daisy chain connections.

Section 5: Power Supply Calculations

5.1 DC Current Draw Calculations

These calculations determine standby and alarm DC current loads for the ACPS-2406 outputs. Tables 5.1 through 5.4 are used to record current draws for each output, and Table 5.5 summarizes the total DC current draw. These calculations confirm the unit's capacity to support connected devices.

5.2 Battery Calculations

Table 5.6 calculates the required battery size (Ampere Hours - AH) based on standby and alarm loads and specified time durations. The ACPS-2406 supports 7 to 25 AH batteries internally. For batteries larger than 25 AH, the internal charger must be disabled.
