RELOCATING THE ANTENNA

Use only the Extension Kits to extend the mounting range of the antenna. Do not cut or splice the

extension cable.

The maximum distance between the LINKS and the antenna is 25 feet (7.62 m) as obtained

by using the LAE-25 Extension Kit. Make sure the antenna is in a physically secured location to avoid tampering.

Secure the TNC connector from the Extension Kit to the mounting bracket, ensuring that the star washers make

solid electrical contact with the mounting bracket.

Remove the antenna from the LINKS cabinet and connect the extension cable to the TNC connector on the

cabinet. Secure the antenna to the TNC connector mounted on the Extension Kit Mounting Bracket.

Locate the mounting bracket and antenna away from possible sources of electrical interference. Moving the

antenna just a short distance will likely be adequate. Temporarily secure the mounting bracket in the new

location and repeat steps 1 - 3 above. If the test gives a good result, perform a test transmission as described

in the “Operations” section of this manual.

If the test is successful and the cellular transmission is completed without a Loss of Cellular Communication

trouble, permanently secure the mounting bracket and antenna at the new location.

Before permanently mounting the LINKS1000 in it’s final location, verify that it is working as it should by

following these steps:

Step 1: Make all connections between the LINKS and the control panel.

Step 2: Power up the control panel and the LINKS1000.

Step 3: Using the four LED’s on the upper left-hand side of the LINKS1000, find the position that gives the

LINKS the best signal strength:

L3 (top, green LED) lit: indicates best received signal strength. Mount the LINKS here.

L4 (second green LED) lit: indicates acceptable signal strength. The LINKS may be mounted here.

L5 (yellow LED) lit: indicates poor signal strength. DO NOT mount the LINKS here as it will probably not

be able to communicate properly.

L6 (red LED) lit: indicates very bad or no received signal strength. DO NOT mount LINKS here, as it will

not be able to communicate.

If a suitable location is not available within the maximum 3ft wire length from the control panel, obtain an Antenna

Extension Bracket kit from your DSC / Sur-Gard supplier. Each kit contains an extension cable, a mounting

bracket, instructions, and all required mounting hardware. Three lengths of extension cable are available:

Extension Kit Length of Cable

LAE-3 3 feet (0.91 m)

LAE-15 15 feet (4.57 m)

LAE-25 25 feet (7.62 m)

1 2 ... 14 15 16 17 18 19 20 21 22 23 24 ... 31 32
