Section 1.2: Installing The NT9010

Please read this section to get an overall understanding of the steps involved in 
installing the NT9010 system. Carefully work through each step. This will help to 
reduce problems and to reduce the overall installation time required.

Check that the following parts are included in your NT9010 package:

• NT9010 main control unit and backup battery

• Two WLS925L-433 transmitters

• One WLS904P-433 motion detector with pet immunity

• One 9V, 20VA plug-in transformer

• One set of Installation, Programming Worksheets and User manuals

• Two 5600

Ω

 resistors

• 4 mounting screws

Draw a rough sketch of the building. Find good locations for the NT9010 control 
unit and all the detectors. Here are some guidelines for choosing good mounting 
locations.

Choosing a NT9010 Mounting Location 
Before you mount the NT9010, you should find a place that is:

• Dry

• Far from sources of interference, including: 

■

electrical noise such as computers, televisions and electric motors in appli-
ances and heating and air conditioning units.

■

large metal objects like heating ducts and plumbing which may shield the 
antenna.

Choosing Mounting Locations for Wireless Devices
Each type of wireless device has its own set of guidelines for mounting locations. 
Before deciding on mounting locations, make sure that you review the guidelines in 
the Installation Instructions that come with each device.

Once you have selected a suitable place for the NT9010 control unit, make sure 
that you will be able to connect the AC power and the telephone line to the 
NT9010. If necessary, have an electrician route AC wiring to the mounting location, 
and have a telephone installer route the incoming telephone line to the mounting 
location.

Mounting the NT9010 Backplate
The NT9010 backplate is the blue-grey piece of plastic that comes attached to the 
back of the NT9010 control unit. This is the mounting plate for the NT9010 unit. It 
also provides terminals for connecting the wiring to the NT9010.
