Note: This chart indicates the maximum distance for 1/4 -2A loads. The wiring distance is from the panel terminals to the last appliance. Use of a
2081-9044 protector reduces wiring distance.
Output of AUX or NAC is 24 V nominal. The minimum voltage is 19.5 at minimum battery; the maximum is 29.5 V. Aux Loads include the compatible
4007ES annunciators series, 4090 series of IDNet ZAMs and IAMs, and any listed device operating within the output limits of the AUX. Calculate the
wiring loss for the actual devices used. Compatible appliances include 4904 series of free-run strobes, 4901 series non-SmartSync horns, 4098 series
TrueAlarm Sounder Base and 4009 NAC extenders, used in reverse-polarity activation mode.

RUI overview
The 4007ES RUI channel supports the following devices:
• 4100-7401, 7402 Graphic Modules.
• 4602-6001, 7001, 7101, 9150 RCU/SCU Modules.
Wire from the power supply's RUI channel on terminal block TB1 to each RUI device. The wiring can be Class A or Class B.

block
Table 27: RUI specifications
Supports: Up to 10 RUI devices.
Electrical specifications:
Channel voltage 29.5 V nominal.
Earth detection threshold 10K ohms minimum from either positive or negative terminals.
Capacitance
The maximum allowed line-to-line capacitance (“+” to “-” terminals) is 0.58uF. For
applications with shielded wire, be sure that the total capacitance from line-to-
line plus the shield to either line is not more than 0.58uF.
Wiring
Maximum wiring distance:
(18 AWG, 16 AWG, 14 AWG, 12 AWG)
2,500 feet (762 m) to device from PSU card.
Maximum T- tapping length 10,000 feet (3,048 m).
Notes:
Maintain the correct polarity on terminal connections. Do not loop wires under terminals. If Class A is not used, configure jumpers P1 accordingly.
Shielded wire is not required. Twisted wire is recommended for improved noise immunity.
