Smoke Detector/Fire Shutdown (FSD) is installed on 580J units
equipped with factory-installed Smoke Detector(s). The smoke
detector controller implements the unit shutdown through its NC
contact set connected to the unit’s CTB input. The FSD function is
initiated via the smoke detector’s Alarm NO contact set. The RTU
Open controller communicates the smoke detector’s tripped status
to the BAS building control. See Fig. 67-71, the RTU Open Sys-
tem Control wiring schematics.
The Fire Shutdown Switch configuration, MENU → Con-
fig → Inputs → input 5, identifies the normally open status of this
input when there is no fire alarm.
Connecting Discrete Inputs
Filter Status — The filter status accessory is a field-installed ac-
cessory. This accessory detects plugged filters. When installing
this accessory, the unit must be configured for filter status by set-
ting MENU → Config → Inputs → input 3, 5, 8, or 9 to Filter Status
and normally open (N/O) or normally closed (N/C). Input 8 or 9 is
recommended for easy of installation. Refer to Fig. 66-71 for wire
terminations at J5.
Fan Status — The fan status accessory is a field-installed acces-
sory. This accessory detects when the indoor fan is blowing air.
When installing this accessory, the unit must be configured for fan
status by setting MENU → Config → Inputs → input 3, 5, 8, or 9 to
Fan Status and normally open (N/O) or normally closed (N/C). In-
put 8 or 9 is recommended for easy of installation. Refer to
Fig. 66-71 for wire terminations at J5.
Remote Occupancy — The remote occupancy accessory is a
field-installed accessory. This accessory overrides the unoccupied
mode and puts the unit in occupied mode. When installing this ac-
cessory, the unit must be configured for remote occupancy by set-
ting MENU → Config → Inputs → input 3, 5, 8, or 9 to Remote
Occupancy and normally open (N/O) or normally closed (N/C).
Also set MENU → Schedules → occupancy source to DI on/off.
Input 8 or 9 is recommended for easy of installation. Refer to
Fig. 66 and Table 24 for wire terminations at J5.
Power Exhaust (output) — The relay used by the RTU Open
board to control power exhaust is a dry contact which means it
does not have 24vac. This 24vac must be connected to the relay to
allow it to operate the power exhaust relay in the PE accessory. A
24vac source must be provided to J11-2 on the RTU Open control
board. This can be provided by the unit’s transformer from various
sources. The “R” terminal on the unit’s central terminal board
(CTB) is a logical source. Refer to Fig. 66 and Fig. 67 or 70 for
wire terminations at J11.
COMMUNICATION WIRING- PROTOCOLS — Proto-
cols are the communication languages spoken by control devices.
The main purpose of a protocol is to communicate information in
the most efficient method possible. Different protocols exist to
provide different kinds of information for different applications. In
the BAS application, many different protocols are used, depend-
ing on manufacturer. Protocols do not change the function of a
controller; just make the front end user different.
The RTU Open controller can be set to communicate on four
different protocols: BACnet, Modbus, N2, and LonWorks. Switch
3 (SW3) on the board is used to set protocol and baud rate.
Switches 1 and 2 (SW1 and SW2) are used to set the board’s net-
work address. See Fig. 84 and 85 for protocol switch settings and
address switches. The third party connection to the RTU Open
controller is through plug J19. See Fig. 86 for wiring.
NOTE: Power must be cycled after changing the SW1-3 switch
settings.
Contact your Bryant applications engineer for more detailed in-
formation on protocols third party wiring and networking.
