INSTALLING THE INDOOR T-ANTENNA

The MSI Hub is supplied with an external hinged antenna that is mounted external to the MSI Hub, and is intended only for indoor use.
For installations where data transmission covers a large distance, such as between buildings, install an Outdoor Antenna in place of the T-antenna. Refer to “Installing an Outdoor Antenna (Optional)” .

CAUTION
The Indoor Antenna must be mounted indoors. Mounting the antenna outdoors may result in damage to the equipment.

NOTE: To achieve the best reception, the antennas of all wireless devices need to be parallel to each other.

1. Screw the antenna onto the external antenna connector on the Wireless TRV.

2. Continue with “Performing the ICMS Configuration” .

INSTALLING AN OUTDOOR ANTENNA (OPTIONAL)

The Outdoor Antenna can be used to replace the Indoor Antenna, and is primarily used to communicate wireless data between distant points (such as in garden apartment installations where the MSI Hub is in one building wile the first TRV is in another, distant building.

To cover a large distance, use two Outdoor Antennas, each connected to a wireless MSI Hub and transceiver.

1. Find an appropriate mounting location to maximize the signal reception for the Outdoor Antenna.
   NOTE
   To achieve the best reception, all antennas of all wireless devices must be parallel to each other.

2. Securely mount the antenna mast (2” [5cm] O.D. pipe) in the desired location. The mast must be mounted vertically.

3. Place the threaded portion of the antenna base through the hole located in the mounting bracket. Secure the antenna to the mounting bracket using the supplied washer and mounting nut.

4. Attach the mounting bracket to the antenna mast using two U-bolts and four washers and hex nuts. Ensure the tightened so that the mounting plate does not move.
