MS/TP Wiring Recommendations
Recommendations are shown in Tables AS and AT. The wire
jacket and UL temperature rating specifications list two acceptable
alternatives. The Halar
1
specification has a higher temperature
rating and a tougher outer jacket than the SmokeGard
cation, and it is appropriate for use in applications where the user
is concerned about abrasion. The Halar jacket is also less likely to
crack in extremely low temperatures.
NOTE: Use the specified type of wire and cable for maximum sig-
nal integrity.
Configuring the UPC Open Controller's Properties
The UPC Open device and ComfortLink control must be set to the
same CCN Address (Element) number and CCN Bus number. The
factory default settings for CCN Element and CCN Bus number
are 1 and 0 respectively.
If modifications to the default Element and Bus number are re-
quired, both the ComfortLink and UPC Open configurations must
be changed.
The following configurations are used to set the CCN Address and
Bus number in the ComfortLink control. These configurations can
be changed using the scrolling marquee display or accessory Nav-
igator handheld device.
Configuration→CCN→CCN.A (CCN Address)
Configuration→CCN→CCN.B (CCN Bus Number)
The following configurations are used to set the CCN Address and
Bus Number in the UPC Open controller. These configurations
can be changed using the accessory display.
Navigation: CCN
Home: Element Comm Stat
Element: 1
Bus: 0

Communicating Zone Sensors
The 48/50P units with factory-installed UPC Open controller
(version 8 or later) are compatible with Carrier ZS communi-
cating zone sensors. Refer to the ZS Sensor Application Guide,
Carrier Sensors Installation Guide, and ZS Zone Sensors User
Guide for additional details.
Carrier Open Control Interfaces
The 48/50P units with factory-installed UPC Open controller
(version 8 or later) are compatible with multiple Carrier i-Vu
Open user interfaces, including Carrier i-Vu Open (Standard,
Plus, and Pro), Carrier Equipment Touch (EQT1-4-CAR) and
Carrier System Touch (SYST1-4-CAR). Refer to the appropri-
ate application, installation, and user guides for additional
details.
Troubleshooting
If there are problems wiring or addressing the UPC Open control-
ler, contact Carrier Technical Support.
COMMUNICATION LEDS
The LEDs indicate if the controller is communicating with the de-
vices on the network. See Tables AU and AV. The LEDs should
reflect communication traffic based on the baud rate set. The high-
er the baud rate the more solid the LEDs become. See Fig. AA for
location of LEDs on UPC Open module.
REPLACING THE UPC OPEN BATTERY
The UPC Open controller's 10-year lithium CR2032 battery pro-
vides a minimum of 10,000 hours of data retention during power
outages.
IMPORTANT: Power must be ON to the UPC Open when re-
placing the battery, or the date, time, and trend data will be lost.
Remove the battery from the controller, making note of the bat-
tery's polarity. Insert the new battery, matching the battery's polar-
ity with the polarity indicated on the UPC Open controller.
