Overview

The AirLink 9900 WireFree signal repeater is designed to receive the transmission from an RKI WireFree sensor assembly and repeat it to the WireFree monitor(s) on your site. The AirLink 9900 features non-intrusive magnetic switches that allow for complete system configuration to be performed in the field, without breaking the enclosure’s seal. Non-intrusive interface with the AirLink 9900 is made possible by the use of the magnetic tool included in the purchase of the device. The AirLink 9900 display screen always shows the current state of communication with the sensor assemblies and receiving monitor devices.
Read this document before the initial operation of the product.

WARNING: The AirLink 9900 is a radio signal repeater used to increase the distance between AirLink sensor assemblies and the receiving AirLink monitor. The AirLink 9900 does not detect or display the detected gas levels in the environment.

A site survey is required in order to determine the best placement and quantity of repeater assemblies that may be required. Improper installation can lead to inconsistent communication between the AirLink sensor assembly and AirLink monitor which could result in personal injury or loss of life.

Installation

This section describes procedures to mount the AirLink 9900 in the monitoring environment and wire the AirLink 9900.

Mounting the AirLink 9900
The primary purpose of the AirLink 9900 is to provide an increase in distance between an AirLink sensor assembly and an AirLink monitor. Proper placement of the repeater is paramount to achieving this goal.
These installation instructions provide only basic guidelines relating to the properties of radio communication and the effects of environmental conditions on the AirLink 9900. Repeater placement should be determined in consultation with the site safety personnel, as well as those knowledgeable of: (1) the site/facility where the equipment is being installed and (2) the potentially present radio interference sources. RKI strongly recommends that a sight survey be performed to determine the best placement of AirLink 9900 repeater devices.

1. In general, consider the following when you select a mounting site:
   •  The receiving and transmitting antennas should be mounted at least 10 feet apart.
   •  Avoid installing the antennas in a location surrounded by obstructions such as trees, buildings, or other such obstacles.
   • Consider accessibility for required maintenance.

2. Select a mounting location and installation hardware. Mounting to a concrete or steel structure is recommended to minimize vibration and moisture. Use a maximum #8 bolt screw, flat washers, Grade 5 material, and corrosion protection like paint, galvanization, or zinc plating to mount the enclosure.

3. Use the included hardware to mount the transmitting antenna.

Wiring DC Power

NOTE: The AirLink 9900 is configured for AC or DC operation, depending on how it is ordered. If you are using AC power as the primary power source, go to the next section, “Wiring AC Power”.
The AirLink 9900 requires +12 to +35 Volts of wired DC to operate. The recommended wire size is anything between 26 AWG and 14 AWG.
CAUTION: The internal components can be static sensitive. Use caution when opening the enclosure and handling internal components.
CAUTION: Make sure the power source is off before beginning the wiring procedure.
CAUTION: DO NOT use any metal objects or tools to remove the terminal board from the internal system.

1. Unscrew the captive screws from the enclosure base. Remove the enclosure lid and set it aside.

2. Grab the handles on the front panel and pull the internal system out of the enclosure. It can rest on
   the edge of the enclosure.
   NOTE: Disconnecting both antenna cable connections from the radio board will allow for the
   complete removal of the internal system from the device enclosure. Disconnecting the internal system may provide ease in accessing the control board terminals for wiring. If this step is performed, it is essential that all connections are rejoined before returning the internal system back into the enclosure. WARNING: Use appropriate construction techniques to maintain the explosion-proof classification
   of the assembly.

3. Feed the power wires through the AirLink 9900’s power hub and into the enclosure.

4. Locate the power terminal block on the control board and complete the following (see Figure 4).
   •  Connect the power (RED) wire to the +12 to +35 VDC terminal.
   • Connect the ground (BLACK) wire to the GND terminal.

5. Route the wires to the DC power source and complete the following.
   • Connect the power (RED) wire to the + terminal.
   • Connect the ground (BLACK) wire to the – terminal.

Wiring AC Power

Figure 4: DC Power Wiring

NOTE: The AirLink 9900 is configured for AC or DC operation, depending on how it is ordered. If you are using DC power as the primary power source, go to the previous section, “Wiring DC Power”.

1. Plug the AC power cord into a power outlet.

Closing the Enclosure

1. Place the internal system back into the enclosure, matching each mounting post to its corresponding eyelet anchored within the base of the enclosure.

2. Using the front panel handles, gently push to seat the internal system into the mounting posts.
   NOTE: The front panel handles on the AirLink 9900 function ONLY as thumb- holds for ease in removal of the internal system from the base of the enclosure.

3. Verify that the sealing ring, seated at the opening of the device enclosure, is correctly in place.

4. Reinstall the enclosure lid by tightly screwing the captive screws into the enclosure base.

WARNING: When securing the lid onto the device, tighten the enclosure lid by hand ONLY. Overtightening of the lid by use of hand tools could result in damage to the O-ring, potentially compromising the moisture seal, resulting in an unsafe environment.
