AGRI-ALERT WIRELESS MODULE
1. SYSTEM OVERVIEW
The Agri-Alert Wireless module allows transparent wireless communication of the
Agri-Alert 9600 alarm system and its sub-modules between livestock buildings. In all,
up to 8 barns (1 master & 7 slaves) can remotely communicate together without
having to bury wires underground.
Hardwired connections usually offer the highest level of reliability. However, in many
situations where traditional cabling is problematic, wireless networking can provide
an interesting alternative.
Why Choose the Agri-Alert Wireless module ?
•Easy installation and advanced radio technology will save you
time and money;
•Overcome the distance and topography problems of hardwire:
- Risky digging situations (presence of buried pipes, cables, gas lines, etc.);
- Obstacles impede the connection between barns (roads, fields, rivers, etc.);
- Barns are a long way apart.
•Seamlessly integrate wireless communication with current
in-place hardwire.
•Use wireless communication to connect a remote distance house
to an existing Agri-Alert system.

1.1 Typical Site
The typical site is composed of a master building and auxiliary buildings. All buildings
(or hardwired subnetworks) have a Wireless module to communicate with each other
using radio frequency (RF) signals. In all, the Agri-Alert Wireless system allows estab-
lishing communication between up to 8 buildings (1 master & 7 slaves) at distances
as far as 6,500 feet (2 kilometers).
The following graphic shows a case where the master building is used in combination
with two auxiliary buildings (house & hardwired subnetwork).
There should be only one Master
Wireless module per site installation.
To know if your module is a
Master or Auxiliary unit, check if there
is a
M
sticker on the radio module.
Auxiliary Wireless modules do not
have this sticker on their radio.

1.2 Typical Installation
Master Building & Master Wireless Module:
A site must have one master building that gathers information from other buildings.
The master building is the place where the Master Wireless module can be found; this
type of module has a radio transmitter that is specially configured to achieve this
function. The Master Wireless module is normally used in combination with an Agri-
Alert 9600 and uses the SBI 28V of the AA9600 system as power source. Hooking up
these two devices allows optimizing the overall wireless communication between
buildings.
Auxiliary Buildings & Auxiliary Wireless Modules:
An auxiliary building is a place where an Auxiliary Wireless module can be found; this
type of module has a radio transmitter configured to transmit information to the
Master Wireless module. In all, up to 8 modules (1 master & 7 auxiliary modules) can
be installed on a site. Auxiliary modules are self supplied using a transformer and
battery box; they are also used to power the alarm system’s sub-modules: TP-800,
KBP-400, KP-400, LB-9600 and Relay boxes.
House:
No distinction is made between barns and houses. In most cases the house is an
auxiliary building that has a keypad and an Auxiliary Wireless module. However, it
becomes the master building if the AA9600 alarm system and the Wireless module are
directly located in the house.

2CONNECTING THE EQUIPMENT
When connecting the equipment to the terminals provided on the main board, strip
the wires as little as possible (about 1/4”) to avoid electrical short circuits. Once the
wires are connected, run them through the electrical knockouts provided on the
bottom of the enclosure and use a watertight cable holders. Additional holes made in
the enclosure will void the warranty.
Use adequate wire gauges when the Wireless module is
placed far from the Agri-Alert sub-modules.
2.1 Supply Inputs
2.1.1 Master Wireless Module
The Master Wireless module is generally powered by the 28V SBI of the AA9600 alarm
system. Make sure the battery and transformer boxes are properly connected to the

2.2 Connecting the Earth Ground
The earth ground terminal of Wire-
less modules and the grounding con-
nection of lightning arrestors must
be connected to the earth ground.
Use a rod at least 5/8” (1.6cm) in
diameter at least 10’ (3m) long. The
rod must have a clean metal surface
free of paint, enamel or other non-
conducting substances. Drive the rod
at least 10’ (3m) into the ground. If
the bedrock is more than 47” (1.2m)
deep, drive the rod into the ground
to bedrock level and bury any remain-
der horizontally at least 2’ (600mm)
below ground level. If the bedrock is
less than 47” (1.2m) deep, bury the
rod horizontally at least 2’ (600 mm)
below ground level (ref. article 10-
702, 3d of the Canadian Electricity
Code C22.10-99).
Use a CSA certified wire of TEW type
or a UL certified wire of type 1015:
Green/yellow, #12AWG, 600V,
105°C insulated wire. We suggest
using a Belden #9912 (color code
#189) or equivalent.
The rod must be connected to the wire described above. It is recommended to let the
rod going out of the ground to connect it. The wire length must not exceed 50’ (15m).
It is extremely important that the earth ground terminal be connected
to a proper ground to protect the electronic components from damage
due to lightning surges and electrostatic discharges. Do not use the
electrical ground for this purpose.
IF OUTDOOR CONNECTIONS ARE USED, MOUNT THE ENCLOSURE
AS CLOSE AS POSSIBLE TO THE ENTRY POINT OF THE OUTDOOR

4.2.2.1 Recommended Positions
The best antenna location is at one edge of the top of the roof as illustrated below. In
this situation, the antenna must be at least 2 feet higher than the roof peak.
Another possibility is to install the antenna on the roof cornice. However, in this case,
the antenna must be at least 4 to 6 feet higher than the cornice. Make sure the roof
does not impede the RF signal transmission.

4.2.2.2 Antenna Height
The height of an antenna basically depends of the following factors:
Distance Between Buildings: The longer the link, the higher the antenna needs to be.
Line of Sight (LOS) & RF Path: All antennas must be mounted in order to have a
direct line of sight with the antenna of the master module. This direct line of sight is
only possible when all antennas have about the same height above mean-sea-level. In
addition, the area around the visual line of sight – the RF path – must be clear from
obstacle or else signal strength will be degraded.
Antenna Height & RF Path Clearance:
The height of the antennas must ensure a complete clearance of the RF Path. This
path has an elleptical shape and is defined based on the greater distance that separates
any two buildings on site. Take the greater distance between two buildings and then
refer to the table in Appendix A at the end of this manual to see what RF clearance
must be respected. This clearance must be present at the midway point between the
buildings, above and below the line of sight (see picture above). Determine the antenna
height accordingly.
PRECAUTIONS:
Do not install the antenna higher than recommended unless
immovable objects are in the RF path. Support cables may
also be required to fix the antenna pole in place.
The antenna height must not exceed 4 feet above the
roof peak; otherwise, it may become a target for lightning.
If you are unable to meet the recommended antenna height
requirement, please get professional help.

AGRI-ALERT WIRELESS MODULE
4.2.2.3 Choosing the Mounting Location
Before attempting to install your antenna, determine where you can best place it to
obtain optimum results. Best performance is achieved when all antennas are close to
each other, mounted at the same height, and in a direct line of sight with no obstruc-
tion in the RF Path. Some examples are illustrated on next page.
STEP 1:
Make an overview diagram of the particular site. Include the following elements:
•Location and orientation of the buildings;
•Distance between buildings;
•Obstacles (trees, bins, roads, fields, etc.)
STEP 2:
Determine the antenna location of each building based on the following requirements:
MakesuretheRFsignalisproperly receivedbyallWirelessmodules beforefixing
any equipment. Refer to section 4.2.3 to verify the received signal strength.
a) Find a mounting place directly above your Wireless module so that the RF
cable can be as short as possible. The provided RF cable has a total length of
25ft (7.6m). If you need to use a longer cable, please contact your retailer.
b) Identify the master building. This building is ideally located in the site’s median
zone, at equal distance from other buildings. Note that the distance between
the Master Wireless module and the Agri-Alert devices must not exceed 500ft
(150m).
c) Identify the location of the AA9600 (it can either be located in the master
building or in the master building’s hardwired subnetwork).
d) Write down the required antenna height (as defined in Appendix A).
e) Make sure the distance between any Wireless building never exceeds 6,500 ft
(2 km).
f) Determine the antenna position for each building. Make sure no obstacle blocks
the RF signal transmission (roof, trees, bins, etc.) It may be required to cut
down trees or to relocate any element that impedes the direct line of sight
between antennas.
If you are unable to meet these requirements,
please get professional help.

4.2.3 Verifying the Received Signal Strength
Indicator (RSSI)
Before making any permanent installation, you must
make sure the radio frequency (RF) signal is properly
received in each auxiliary building. Status leds indicat-
ing the received signal strength (RSSI) are located on
the circuit board of each Wireless module. These pilot
lights indicate how well Auxiliary Wireless module com-
municate with the Master Module.
It is also possible to check the communication statistics
directly on the AA9600 system (see section 4.2.3.2).
4.2.3.1 Verifying the Signal on the Auxiliary Wireless Module
Checkthe RSSI onthe Auxiliary Wirelessonly
(the signal strength on the Master module is
not suitable).
At least 2 RSSI LEDs must be lit on each
Auxiliary wireless module for the system to
have accept able performances (Fair signal
reception).
a) Choose a fix location for the Master Wireless
module and its antenna. Antenna positions in
auxiliary buildings will be based on the master
building.
b) Power the Master Wireless module and the
AA9600 unit.
c) Mount a second antenna on rigid PVC pipe and
connect it to an Auxiliary Wireless module.
d) Power the Auxiliary module using a battery.
e) Position the antenna next to the auxiliary build-
ing and verify the received signal strength.
Permanent antenna installation can be performed
if at least two RSSI LEDs are lit.

(Advanced function)
On the AA9600 :
1. Press the System key.
2. Enter the installer’s password (9601 by default) and press Enter .
3. Select the PROGRAM AUX’S menu and press Enter.
4. Select the INFORMATION menu and press Enter.
5. Enter the number associated with the device you want to access from a remote
location and press Enter.
6. Communication statistics on the selected device are displayed: the Loss value
repesents the number of packet loss and the Total represents the number of sent
packets (the total value automatically goes back to 0 once it reaches 65000 or after
a reset)
7. Press the right-arrow key to reset the communication statistics.
8. Wait until the total number of packets reaches 500 and check the number of packet
loss at that moment. In an excellent installation, the amount of packet loss would be of
15 out of 500 or less (3% loss). This loss rate is only reached in perfect conditions, an
application can be functional with a higer packet loss rate.
If you want to improve your communication statistics, try relocating the antennas
and make sure the cables are in good working conditions.
