Installation and Operation
1.3.6 Remote Temperature Sensor (NL4/NLX only)
The remote temperature sensor allows measuring a tem-
perature up to 6 feet away from the NL4 or NLX board. Plug
the sensor into J18 and run the sensor wire to the area or
device to be monitored.
1.3.7 Connecting the ADC (Voltmeter) Input
When using the voltmeter input, connect one end of the ADC
cable to the ADC1 input on the Netlink board. Cut off the other
end of the ADC cable and connect it to the voltage source to be
monitored, observing polarity. The red wire is the positive in-
put and the black wire is the negative (DC Common) input. The
ADC cable wiring must be routed away from high voltages and
the wire used must be rated for the voltages and temperatures
in the area in which it is installed.
i Note: The voltage being measured by the ADC input MUST
be common grounded with the voltage source of the Netlink
board.

1.3.8 Wiring the Control Outputs
The NLX provides Form C relay contacts which may be used
directly for control. These relays are rated for 1A maximum.
The NL2 and NL4 provide a low-current open collector out-
put. When using the control outputs, connect one end of
the Control Output cable to the Control Outputs connector
on the Netlink. Cut off the other end of the control output
cable. The wire going to the pin on the connector labeled
"FLT" is Control Output # 1. The wire going to the pin labeled
"EN_FAI" is Control Output #2.
The Control Outputs are low-current, open collector (tran-
sistor) outputs which pull to ground when activated. These
outputs can be used to activate sensitive trip relays such
as LifeSafety Power's RB Series, supply the ground side to
an FAI Input, or other similar uses. See Figure 1.8 for an
example using an RB relay.
i Note: Do not connect these outputs directly to a voltage
source or damage to the Netlink will occur. Also, ensure the
wire used is rated for the voltages and temperatures in the
area which it is installed.
