Installing the Exciter
• Ensure that the power supply and network are turned
off to prevent electrical shock or damage to equip- ment.
• Touch your hand to ground to discharge any electro-
static charge before handling the LAR.
The steps below correspond to the numbers in Figure 1. 1 Record the LonWorks ID number. Locate and record the LonWorks identifi cation number onto
the facility fl oor plan indicating the LAR’s position and network wiring path. Use the tear-away sticker on the LAR’s Neuron ID label.
2 Remove the Mounting Plate from the LAR. If the LAR is to be installed to a receptacle box, pass the network
and power supply wires through the hole in the Mounting Plate. (For other installations, the wires are passed through the slot on the side of the LAR case in Step 5.)
3 Wire the terminal block. Connect the LonWorks Network IN, Network OUT, and
Power Supply to the terminals. If the LAR is at the end of the network, then terminate the network segment with Item A (105 Ω terminator). Ensure there is at least 10 ft. (3 m) of slack
in the cable to allow the possible repositioning of the LAR.
4 Install the Mounting Plate. Referring to the facility fl oor plan, decide the position of the LAR.
Do not place near metal objects and structural frames. Ensure that the service light will be visible and that space is allowed for the antennas. Unless there is a conduit tray, run the cables at least 1 ft. (30 cm) up and away from the LAR.
Install the mounting plate using one of the following methods. A Fasten to a suspended ceiling guy wire, using: • 1 multi-function Caddy clip • 2 machine screws • 2 hex nuts • 2 lock washers B Install directly to a ceiling or a wall using: • 2 wood screws • 2 hollow wall anchors C Install to a receptacle box, using: • 2 machine screws
5 Install the LAR to the Mounting Plate.
Plug the wired terminal block into the LAR and install the LAR onto the Mounting Plate, using the screw removed in Step 2. DO NOT place excess network and power supply wires inside the LAR case.
6 Attach the two antennas. The antennas have a protective covering to prevent them from
touching metal. For best coverage, ensure that they are at least 2 ft. (60 cm) from metal objects. Do not encase, wrap, or otherwise cover the antennas.
Installation is complete. Proceed to Final Steps below.

Installing the LAR
Installation Considerations
• Position the LAR beneath ceiling obstructions—When
mounting above drop ceilings, mount the LAR below metal duct work, pipes and foil-backed ceiling tiles.
• Route cables up and away from the LAR—When the cable is
not in conduit, keep it at least 1 ft. (30 cm) from the LAR.
• Install the LAR temporarily until testing is complete—Fasten-
ings should be secure enough that the LAR can be permanently mounted without disturbing its orientation.
• Point the secondary antenna into a clear area, away from
metal objects—The main antenna always points downwards, but the orientation of the secondary antenna is adjusted to suit site conditions. Point it away from metal objects, and make sure it is not running parallel to cabling in the ceiling.
• Observe temperature and humidity restrictions—Refer to the
Specifi cations table.
• Leave slack in the cable—Leave at least 10 ft. (3 m) of slack in
the communication and power cable to allow for adjustments in the location of the LAR.
• No user adjustments to internal circuitry—Tampering may
cause component or system failure, or both, and will void the warranty.
Final Steps
Do not supply power to the LAR or any other network device until all connections are complete.
Once all devices are installed, power up the LAR and other devices. In the Xmark™ software, run Auto Confi gure to install the new devices, and then confi gure them for operation. The coverage area of the LAR must also be checked. Refer to the Hugs Installation Manual (p/n 805I0301) or MyCall/ FindIt Installation Manual (p/n 805I0401) for detailed informa- tion on how to complete these steps.
