This section describes the hardware on the 4009 board. Use Figure 1-2 to locate the items
described on this page.
The Addressable Controller system board provides three TrueAlert SLC channels. Channels 1
through 3 are Class B TrueAlert signaling line circuits. Field wiring terminations are provided for
12 AWG to 18 AWG wire (twisted pair wire is required). Refer to Field Wiring Diagram 842-158
for complete wiring, compatible appliances, current, and line distance information. Each channel
is capable of being independently controlled by the TrueAlert 4009, as commanded by the host
panel and Dip Switch SW5 settings.
Each signaling line circuit is monitored for short and open circuit line faults when in the standby (not
energized) condition. In the event of a short circuit, the Addressable Controller will not activate the
SLC channel while the short circuit fault is present. Short and open circuit faults are reported to the
host panel via the command channel (IDNet, RUI, or hardwired) and can be identified by a steady
trouble LED on the Addressable Controller during the supervisory state.
The channels are configurable as Class A (Style 6) circuits with the addition of the
4009-9812 Class A Adapter Option Card. The Addressable Controller monitors for insertion of the
Class A Adapter Option Card, and detects it when it is configured properly via Hardware
Configuration Switch SW4 (see Table 2-1 in Chapter 2).
On power-up, or on controller reset via DIP switch SW4 (IDNet and Hardwired only) or SW5,
each channel momentarily disconnects its supervision, allowing earth fault isolation.
The battery charger charges lead acid batteries up to 18 AH (refer to Field Wiring Diagram
842-158 for details). Low, missing, and depleted batteries are detected through supervision. The
battery charger output remains disabled until a battery is sensed. The 4009 does not support
external chargers.
The control interfaces for IDNet and RUI are TB1 and TB2. Use these ports as described in Field
Wiring Diagram 842-158.
DIP switches are used to configure the system, as described in Chapter 2.
