Commission the devices on the MS/TP Bus using the Controller Configuration Tool (CCT) software.
Applications and device configurations are downloaded to the hardware from the CCT computer using
the Wireless Commissioning Converter or through the NAE from the User Interface (UI).
Hardware points can be auto discovered from the online UI of the NAE, the Application and Data Server
(ADS), or the Extended Application and Data Server (ADX).
NU-RPT101-OU RS-485-to-RS-485 Repeater
Install the repeater inside a UL Listed enclosure (see Enclosu�es and Accessories). The repeater provides
isolation on the FC Bus end of a smoke control system. Input and output wiring is supervised and
power-limited. The repeater has non-power-limited wiring for the input power source.
The NU-RPT101-OU repeater serves two purposes:
L Isolate Smoke Control equipment from Non-Smoke Control equipment.
2. Extend the physical length of the FC Bus on a single Smoke Control FC Bus.

Wiring
Transient Protection
Install tranzorbs on the NU-RPT101-1U on both terminal blocks TB1 and TB2. The tranzorbs must be
from tranzorb kit SMOKE-TRNKIT-1, which must be ordered separately. See SMOKE-TRNKIT-1 U
Tranzorbs on page 123 for more information.
Note: Two SMOKE-TRNKIT-1 tranzorbs are required (one for TB1 and one for TB2) to protect the
NU-RPT 101-1 U repeater.
Install the SMOKE-TRNKIT-1 tranzorbs to terminal blocks TB1 and TB2 using the following
procedure(Figure 86):
1. Starting with TB 1 (Far Side), strip the FC bus wiring to 0.5 inches.
2. Twist the single wire side of the first tranzorb to the FC COM Far Side wire.
3. Attach the twisted FC COM wires to the TB1 COM terminal.
4. Twist the FC+ Far Side bus wire together with one wire from 2-wire end of the first tranzarb.
5. Attach the twisted wires to the TB1 D+terminal.
6. Twist the FC- Far Side bus wire together with the remaining 2-wire wire from the first tranzorb.
7. Attach the twisted wires to the TBl D- terminal.
8. Repeat the process for TB2 (Near Side).
Note: The SMOKE-TRNKIT-1 tranzorb has no polarity. FC Bus wire colors may vary from this
example.

End-of-Line The EOLN termination network is enabled for the A side or B side when the associated
Termination Network pair of jumpers are positioned over pins 1 and 2.Conversely,the EOLN is disabled (out
of the circuit)when the pair jumpers are positioned over pins 2 and 3.
The EOLN termination network is individually selected on both the A and B sides by a
pair of shorting clips.The A-side is controlled by jumper pair J1, J2 and the B-side is
controlled by jumper pair J3 and J4
Duplex Half-duplex only
Data Format Ten bits typical (1 start bit, 8 data bits, and 1 stop bit). Other formats are supported.
