Optional Equipment
Smoke detector(s)
A factory installed smoke detector is designed to
sense smoke concentration in the return air
stream. Upon detecting smoke concentration an
audible and visual alarm will be activated and
the unit will immediately shut down.
Firestat
A Firestat is available for installation in the air
stream. If the return air temperature reaches
125° F (52° C), the air conditioner will be turned
off and both an audible and visual alarm will be
activated.
Water detector(s)
The solid-state water detector activates an
audible and visual alarm on the microprocessor
when moisture is detected. The water detector is
provided with 15’ of wire.
Remote relay shutdown
A factory installed relay can be ordered with a
24V, 120V, or 240V coil to remotely disable the
NetworkAIR system.
Essential/non-essential lockout
When facilities have limited backup power
capacity, this lockout prevents the operation of
electrical loads that are not essential for
continued site operation.
Floorstand
The heavy gauge floorstand raises the unit
above the subfloor to match the height of the
raised floor. Heights are available from 6” to 36”
in 3” increments. Adjustment is provided by
threaded pedestals.
Air deflector
An air deflector ships loose and attaches to the
floorstand for changing air direction from vertical
to horizontal.
Plenum
The discharge plenum mounts on top of the
upflow unit to direct and distribute conditioned
air. Manually adjustable, double deflecting grilles
are provided on 3 or 4 sides.
Duct flange
A 1” (25mm) duct flange is installed on a unit to
provide convenient connection to external
ductwork. The duct flange can be installed at the
air outlet on upflow units, at the air inlet on
upflow rear return units, or at the air inlet on
downflow units.
Dry contact closure alarms
Each unit can be equipped with any or all of the
listed dry contact closures. Upon activation of
the associated
alarm, a discreet Normally-Open or Normally-
Closed contact is available for remote
monitoring of that discreet alarm.

Redundant group control
Allows up to six NetworkAIR units the ability to
communicate with each other to automatically
switch upon alarm condition, or timed rotation.
Can also allow standby units the ability to assist
the running system.
Remote display panel
The microprocessor controller allows facility or
building-maintenance personnel to evaluate and
control the unit from up to 50 ft. away from the
unit, without having to enter the secured space.
Remote sensor(s)
Environmental sensors can be strategically
placed, up to 50 ft. from the unit to better meet
the sites cooling needs. The sensor must be
positioned to permit air movement across the
sensors.
