JOHNSON CONTROLS

OPTIONAL SHIPMENT IN MULTIPLE SECTIONS

The unit shall be shipped in sections. Assembly in the mechanical room shall not require 

interconnection of refrigerant or condenser water piping between sections. All control 

wiring connections between sections shall be through connector plugs. Should unit dis-

mantling and reassembly be required, the contractor shall bear the cost for this work and 

ensure the manufacturer’s warranty is not voided.

BUILDING AUTOMATION SYSTEM (BAS) INTERFACE

BACnet

®

 MS/TP communication protocol shall be available.

Common Alarm Output

This binary output signal is used to indicate an alarm signal. When the unit controller 

has processed an alarm condition, the normally closed dry contacts shall open. When the 

alarm has been cleared, the contacts shall return to the normal closed position.

Outdoor Air Damper Output

Occupied/Unoccupied output signal on/off signal is used to control the outdoor air damper. 

Off corresponds with a closed damper and open with a fully open damper for outdoor air.

VAV Box/Heat

This binary output signal is used to put the VAV box in a heating or cooling mode. When 

the normally open contacts are closed, this represents a heating mode, and the VAV box 

should be at the maximum position. When the normally open contacts are open, this rep-

resents a cooling mode, and the VAV box should be in the cooling mode and maintaining 

the space/zone temperature. Voltage for the device(s) connected to the output needs to be 

provided from another source.

External Stop (Fan Stop)

This binary input signal is used to shut the unit down in an emergency. When the signal 

is open, the unit is in the shut down emergency mode. Thus, the unit is in the unoccupied 

mode. When the signal is closed, the unit shall be operating in the typical. After the unit 

has been in the emergency mode, when the signal is closed, the unit shall be controlled in 

the normal manner. Reset is not needed unless an alarm condition has occurred.

Cool/Heat Enable

The keypad shall be used to enable or disable cooling and heating and allow the unit to 

be in the fan on mode. In the fan on mode for VAV units, the unit shall control duct static 

pressure. 

OPTIONAL ACCESORIES
Discharge Plenum

Units shall be provided with an optional acoustical discharge plenum shipped loose for 

field installation. The duct opening(s) in the discharge plenum shall be located for hori-

zontal duct connection(s). Single [Multiple] duct opening size(s) and location(s) shall be 

coordinated with the factory. Duct openings for the discharge plenum shall not require 

field cutting or modifications.
The discharge plenum shall be constructed of formed 16-gauge pre-painted galvanized 

steel. The exterior panels shall be fabricated from 18-gauge pre-painted galvanized steel.
