4 Reference & Installation Manual
The following sections will detail how to mount and connect the Omnia Wireless
Receiver Module (OMN-RCV3).
2.1 LOCATION
Mount the Omnia Wireless Receiver on a wall allowing at least 5cm (2”) around the
module to permit adequate ventilation and heat dissipation. Select a site that is not
susceptible to drastic temperature changes. Avoid installation near or in the path of
strong RF fields (i.e. neon lights, computers), on or near metal objects, circuit
breaker boxes, air conditioners, and heater ducts since they may cause interference
and reduce the module’s sensitivity. We recommend installing the module in a
centralized location on the main floor. Avoid installing the module in the basement.
Refer to the appropriate Spectra Reference & Installation Manual for maximum
allowable distances between the control panel and the Wireless Receiver Module.
2.2 CONNECTIONS AND MOUNTING
Firmly screw the antenna into the connector marked "
ANT
" on the Receiver Module
as shown in Figure 2.1 on page 5. Using a drill or screwdriver, punch out the four
mounting holes on the back of the plastic case. Align the six holes of the printed
circuit board with the six pins on the back plastic mounting case and snap into place.
If placed correctly, the antenna will lean directly over the groove in the mounting
case.
Do not cut, bend, or alter the antenna. Avoid mounting the Receiver
Module near or on metal as this may affect the module’s sensitivity.
Do not connect more than one OMN-RCV3 module to the control panel.
The OMN-RCV3 does not function with the 1758/1758EX Spectra
control panel.
The Omnia Wireless Receiver Module is connected to the Spectra control panel's
communication bus in a star or daisy chain configuration. Refer to Figure 2.1 on
page 5.
