Overview
The AirLink 5950 is a WireFree Switch-State Transmitter for use in conjunction with a new or
existing WireFree system.
The AirLink 5950 receives signals from up to two individually addressable sensors (pressure
switch, temperature sensor, flow sensor, tank level sensor,etc.), and then transmits the state of
(and change of state of) that switch.
This document should be read before initial operation of the product.
NOTE: The figures and enclosure wording in this manual represent the AirLink 5950 XP;
however, the AirLink 5950 NXP’s internal components and operation are identical.

Sensor Wiring Setup
NOTE: The figures and enclosure wording in this manual represent the AirLink 5950 XP;
however, the AirLink 5950 NXP’s internal components and operation are identical.
Although applications will vary, most switches use three wires: normally open (NO), common
(COMM) and normally closed (NC).
On the opposite side of the board from the terminals there are two switches which determine
whether the NO or NC side of the connected switch is being monitored by the control board.
If the side being monitored is open, a “0” will appear on the screen and be transmitted. If the side
being monitored is closed, a “1” will appear on the screen and be transmitted.
Wiring to Sensor 1
The AirLink 5950 is a wired transmitter that uses an external 4 - 20 mA sensor provided by the
user. Refer to the following procedure when wiring the Sensor 1 to the transmitter.
1. Power off the device by touching and holding the magnetic wand against the right side of the
device for four seconds to activate SUB.
2. Unscrew and remove the enclosure lid.
3. Grip the front panel thumbscrews and pull the front panel out of the enclosure.
CAUTION: Do not use any metal object to help remove the front panel. Do not
remove any connecting wires.

4. Locate the Sensor 1 terminal block on the control board and rotate the board so that the
terminal block is accessible for wiring.
CAUTION: Use appropriate construction technique to maintain the explosion proof
classification of the assembly.
5. Connect a wire (red) from Sensor 1 to the terminal labeled “NO” on the Sensor 1 Terminal
Block.
6. Connect a wire (black) from Sensor 1 to the terminal labeled “COMM” on the Sensor 1
Terminal block.
7. Connect a wire (green) from Sensor 1 to the terminal labeled “NC” on the Sensor 1 Terminal
Block.

8. To wire in Sensor 2, proceed to the next section. To finish wiring Sensor 1, replace the unit
back in the enclosure by matching each mounting post to its corresponding eyelet inside the
enclosure.

9. Verify that each mounting post is properly fitted in its corresponding eyelet inside the
enclosure.
10. Verify that the sealing ring (located on the threads of the open enclosure) is still in place.
11. Place the enclosure lid on top of the enclosure base.
12. Rotate the lid until it is tightly screwed in place (approximately 20 rotations).
Wiring to Sensor 2
The AirLink 5950 is a wired transmitter that uses an external 4 - 20 mA sensor provided by the
user. Refer to the following procedure when wiring Sensor 2 to the transmitter.
1. Power off the device by touching and holding the magnetic wand against the right side of the
device for four seconds to activate SUB.
2. Unscrew and remove the enclosure lid.
3. Grip the front panel thumbscrews and pull the front panel out of the enclosure.
CAUTION: Do not use any metal object to help remove the front panel. Do not
remove any connecting wires.
4. Locate the Sensor 2 terminal block on the control board and rotate the board so that the
terminal block is accessible for wiring.
CAUTION: Use appropriate construction technique to maintain the explosion proof
classification of the assembly.
