APC NetworkAIR™ FM-DX 47
G. CABLE WATER DETECTOR
1. A leak detection sensing cable shall be shipped loose with the unit. If water or other
conductive liquids contact the cable anywhere along its length, the main controller
visually and audibly annunciates the leak.
2. The detector shall be provided with 20ft (6 m) of cable. Cable may be cascaded up to 500ft
(152.4 m).
H. ADDITIONAL PROGRAMMABLE INPUT/OUTPUT INTERFACE MODULES
1. Each system shall be equipped with up to 3 additional discrete input/output modules for a
total of 16 inputs/outputs. Each interface module shall be programmable with outputs that
can map from any system alarm through the microprocessor controller. Inputs shall be
capable of mapping to outputs as a system alarm or custom alarm.
I. FIRESTAT
1. A firestat shall be factory-installed in the return air to sense heat and send a signal to the
main controller shutting down the unit and activating a visual and audible alarm.
J. SMOKE DETECTOR
1. A smoke detector shall be factory-installed in the return air to sense concentrations of
smoke and send a signal to the main controller shutting down the unit and activating a
visual and audible alarm.
K. SPOT WATER DETECTOR(S)
1. A water detector shall be factory-wired and shipped in the bottom of the unit to sense
water and send a signal to the master control giving the operator possible alarm indications
options for shutdown. The water detector shall be provided with 15 ft (5 m) of wire.
L. FLOW SWITCH
1. Single pole, double throw shall moderate fluid flow when it exceeds or drops below the set
flow rate. Flowswitch shall ship loose for field installation.
M. NETWORK CABLE - REDUNDANT GROUP CONTROL
1. Network cables shall be available in 25’, 50’, 100’, or 200’ lengths to ship with your
cooling system. The network cable shall be used to interconnect multiple cooling units in a
redundant group, as well as to connect the network management card to your LAN.
