4. Mount the back box to the wall so that the top of the enclosure is no more than eight feet
above the floor. The back box must be level and plumb. For surface mounting, use the
teardrop and clearance holes located in the rear of the box and screw to wall.
5. Wire non-power limited wiring in the shaded areas only (see Figure 2-5), this includes AC
input and battery connections. All other wiring is power limited. Maintain at least ¼-inch
(0.63 cm) spacing between all power limited and non-power limited wiring.
6. Connect the AC wiring harness and install the electronic card cage assembly to the 4009
cabinet.
When wiring the 4009 TrueAlert Addressable Controller, refer to Field Wiring Diagram
842-158, the 4009 TrueAlert Applications Diagram (Figure 2-1), and the following system wiring
requirements.
• All wiring, except incoming power and ground connecting wires, must be free from
grounds or shorts and have a resistance of one megohm, or higher, to earth.
• All wires are to be copper conductors only, except fiber cables. 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 National Electrical Code.
• If shielded wire is used, the 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 one megohm to earth.
• Splicing is permitted in accordance with NFPA 70 National Electrical Code. All wiring
must be terminated with UL listed appliances (e.g., wire nuts, pressure connectors).
Wiring terminated with only electrical tape is not permitted. All splicing (free ends of
conductors) must be covered with an insulation equivalent to that of the conductors.
• An appropriate system ground must be provided for earth detection and lightning
protection appliances. The connection must be an approved dedicated earth connection
per NFPA 70 National Electrical Code.
• When running wires to the 4009, identify the wires appropriately. Only system wiring
can be run in the same conduit which includes SLC wiring, NAC wiring, IDNet wiring,
RUI wiring, 24 V AUX wiring, and FACP speaker circuits.
• Input power and external battery power are non-power limited and cannot be run
with power limited system wiring.
IMPORTANT: If the 4009T is powered up with zero devices connected, the 4009T will
indicate channel failure for those channels that are programmed to support
devices. The 4009T will not sense devices as they are connected when the
4009T has been powered up with zero devices connected. After at least one
valid device is connected, the unit must be reset by toggling dipswitches on
Hardware Configuration Switch SW4 (SW4-2 for example) and then the
4009T will communicate with devices as they are added.
