Interlogix Simon XTi CDMA Module V4 - Manual (Page 2)

• Before affixing the panel to a wall, verify the CDMA signal
level at the installation location. On the XT panel, press and
hold the 5 Key for 10 seconds to view the signal level. On
the XTi panel, enter ‘Programming’  ‘Interactive Services’ 
‘Module Status’. With either panel, module LED L4 blinks
toindicate signal strength. (See Tables 1-3 for LED details.)
An installation location with a sustained signal level of two
or more bars is recommended.
• Do not exceed the panel total output power when using
panel power for the CDMA module, hardwired sensors, and
/or sirens. Refer to the specific panel installation instructions
for details.
• Only one Alarm.com CDMA module can be used per panel.
• Avoid mounting the panel in areas with excessive metal or
electrical wiring, such as furnace or utility rooms.
• Leave 12 to 18 in. of open space around the module antenna.
• Do not install the control panel and module in a basement or
other below-ground location. Doing so will negatively impact
CDMA signal strength.
Tools and supplies needed
You will need the following tools and supplies:
• Small flat-head and Phillips screwdrivers

3. Push antenna end into module connector to snap the
antenna onto the module. The module must be seated
correctly beneath the two small, plastic corner tabs (see
Figure 3 below) to ensure it fits into the compartment
properly.

Make sure the module is BELOW the two corner tabs.
4. Insert the module by angling the end of the module where
the antenna is attached downwards, making sure that the
edge of the module sits below the plastic tabs (see Figure 3
above). Once the module is seated evenly, carefully push the
bottom of the module into the 8-pin connector beneath it.
5. Thread the antenna’s wire through the channel in the bottom
of the panel. This antenna can then be inserted into the wall
behind the panel. The antenna should be placed at least 3
feet away from the panel, and in order to obtain optimal
reception the antenna should be affixed as high up as
possible.
