6APC NetworkAIR™ FM-DX

Standard Features

Double Skin Panels

The frame is bolt together 12 gauge

formed steel for maximum strength.

Cabinet is serviceable from the

front. All exterior panels and corner

posts on the frame are powder

coated for durability and an attrac-

tive finish. Front exterior panel

crowne is 16 gauge. All other pan-

els are double skin, 24 gauge

exterior, 24 gauge interior with 1 ½

lb. (.68 kg) per cubic foot insulated

for quiet operation. Insulation is

CFC-free and recyclable. Double

skin panels isolate insulation from

the air stream and further reduce

sound levels. Left and right front

panels are hinged and removable

for easy access. Middle panel is

removable.

Direct Drive Motor/Blower

Assembly

Each cabinet includes a precision

balanced centrifugal blower assem-

bly(s) that is balanced to less than 1

mil displacement on all axis for

quiet, reliable operation. The blow-

ers are mounted based on mass and

frequency to eliminate vibration

and noise. A direct drive (L

500,000 hour bearing life) motor

and frequency controller are used

with each blower in the system to

enhance user functionality. Each

unit is equipped with two blower

assemblies.

Frequency Controlled Motor

A frequency controlled drive is

installed for each direct drive

blower motor. The frequency con-

troller communicates with the

microprocessor controller allowing

user adjustable rpm settings via the

main display. This makes field air

balancing quick and easy. Field air

balancing is a common after

thought that can be expensive and

lead to back-charges. Each time the

fans are started, the frequency con-

trolled drives control the ramp-up

of fan speed. This thirty second soft

start lowers the in-rush current and

reduces the locked rotor amps used

when sizing generators.

Tandem Scroll Compressors

The refrigeration system operates

under a master controller for greater

efficiency and accuracy. Suction

and discharge pressures are moni-

tored and electronically controlled.

Tandem scroll compressors are

designed for year-round operation

with a 15-year life expectancy. The

microprocessor controller provides

real-time suction and discharge

pressure readings reported by trans-

ducers installed on the refrigeration

system.

Electrical Panel

The electrical panel contains the

contactors, starters, overload pro-

tection devices, and input power

disconnects.

Evaporator Coil/94VO Thermal

Condensate Pan

Evaporator coil is 1/2" rifled, cop-

per tube, with raised aluminum fins.

Condensate pan is 94V0 thermal

formed, anti-fungal, non-ferrous

material for higher indoor air qual-

ity. Evaporator is configured as a V

coil.

Programmable Input/Output

Interface Module

The main module provides field

connections through a system pro-

grammable input/output module.

Up to three additional input/output

interfaces may be added to the main

module. Each interface module is

programmable with inputs that can

be mapped to any system alarm or

annunciated to outputs as a system

alarm or custom (12 character)

alarm.

Main Power Circuit Breaker(s)

A nonautomatic main power circuit

breaker disconnects all high voltage

power to the unit if necessary. The

disconnect switch is accessible

without removing the electric box

cover.

Redundant Group Control

Allows up to 4 groups of 3 FM

units to communicate with each

other for redundancy, demand fight-

ing prevention, mode assist, and

global sharing of certain settings.

Requires standard network cable

interconnection.

Network Management Card

Permits multi-level access to moni-

toring, control, and event

notification features over the user’s

network.

Evaporator Freeze Protection

Suction pressure is actively moni-

tored and controlled to eliminate

risk of condensate freeze-up on the

evaporator.

Predictive Failure Warnings

Several components within the unit

will provide a warning that service

is needed prior to failure occurring.
