Chapter 2 Installation
Wiring
Wiring Guidelines • Wires must not be run through elevator shafts.
• Only system wiring can be run together in the same conduit.
When powering remote units through relay contacts, power for these circuits must be
provided by a PL power supply listed for fire-protective signaling use. An end-of-line
(EOL) relay must be used to supervise the auxiliary power circuit.
• Connect the output of the EOL Relay to cause a trouble. Wire in series with the EOL resistor
on an available Initiating Device Circuit (IDC) or Individual Addressable Module (IAM).
Safety Ground Proper operation and protection against transient energy per UL 864 and ULC-S527 requires
connection of safety ground wire to cabinet chassis. Connect safety ground before wiring any
other circuits to the panel.
AC Supply Wiring Adhere to the following guidelines when wiring AC Power.
• AC power must be wired from a dedicated circuit breaker or fuse, rated no more than
20 A, per NFPA-72, NEC, and local codes.
• Before handling AC feed, verify that it is not live using a voltmeter. Make sure the circuit
is de-energized and tagged to prevent injury.
• AC supply wiring must be 14 AWG minimum to 12 AWG maximum.
• Connect a 12 AWG copper ground wire from safety ground in the electrical distribution
panel to the panel safety ground stud.
• Input voltage:
- 120 VAC, 50/60 Hz
- 240 VAC, 50/60 Hz
- No configuration settings required to select.
Battery
Guidelines
• A fused harness (harness 734-304 for NAC power supply and 734-303 for IDNAC power
supply) is required to connect the backup batteries. That harness is shipped with the panel.
The mating spade lug on the battery should be 0.250” X 0.032". If another size is needed,
you will need to replace the battery terminal connectors on the supplied battery harness.
• The 4007ES battery charger supports up to 33 Ah batteries (maximum) within UL864 and
ULCS527 guidelines.
- 18 Ah batteries can fit inside the box.
- 25 Ah and 33 Ah batteries use 2081-9282 (red 25 Ah or 33 Ah) or 4009-9801 (beige
25 Ah)
• To minimize the power losses due to wiring from the external battery box to the 4007ES,
use at least a 12 AWG wire. Mount the battery box within 20 feet of the panel in
accordance with the mounting instruction label in the box. All interconnecting wiring must
be enclosed in conduit.
• Seismic battery brackets can be used internal to the 4007ES box (2081-9401 (12.7 Ah
bracket), 2081-9402 (18 Ah bracket)). For more information on how to install the seismic
brackets, refer to Battery Bracket installation instructions 579-944.
