optional communication module intended
for use with the VISTA
and provide cellular radio communication with the AlarmNet
network for de
livery of alarm and other messages to the
monitoring central station.
Use of this module requires an AlarmNet
-I account. If an
account for the control does not yet exist, please obtain
the account information from the central station prior to
programming this module.
This kit contains the following components:

installation, affix the “Contains Transmitter
label to the outside surface of the control
panel cabinet so it is visible.
Install the Antenna Adapter Plate
a. Punch out the large wiring-hole knockout and the
adjacent smaller knockout from the cabinet’s upper
and left topside.
b. Position the antenna adapter plate over the large
knockout, aligning the plate’s pin with the smaller
knockout and push until the adapter snaps into place.
c. Remove the nut and washer from the antenna adapter
cable then secure the cable’s SMA connector to the
adapter plate with the washer and nut as shown.
Install the Antenna
The antenna(s) used for this tr
ansmitter must be
installed to provide a separation distance of at least 7.8 inches (20
cm) from all persons and must not be co-
located or operating in
conjunction with any other antenna or transmitter except in
accordance with FCC multi
Mise en Garde
Exposition aux Frequences Radio:
La/les antenne(s) utilisée(s)
pour cet émetteur doit/doivent être installée(s) à une distance de
séparation d'au moins 20 cm (7,8 pouces) de toute personne et ne
pas être située(s) ni fonctionner parallèlement à tout autre
transmetteur ou antenne, excepté en conformité avec les
procédures de produit multi transmetteur FCC et ISEDs
The antennas mount
directly onto the antenna adapter cable
at the antenna adapter plate.
Carefully align the antenna’s connector over the SMA
connector protruding from the adapter plate, then screw it
down (clockwise) until it is finger tight. Do not over tighten.
Initial Power Up
: Upon initial power up, the communicator LEDs blink in repeated sequence from
bottom indicating network initialization.
This sequence may take up to 15 minutes.
Do not reset power during this time.
When initialization is complete, the Signal Quality display LEDs will light and the
yellow and red LEDs may blink (per their
After initial network setup, subsequent resets or power ups can take up to 90 seconds.
/ Mode and Status LEDs normally display
the module’s signal q
. LED 1 (red LED on the top) will
be lit to indicate that the display is in signal quality
the other LEDs indicate signal strength (lowest to highest,
from left to right) between the module and the receiving
This allows you to immediately determine if the
desired mounting location has sufficient signal
strength for proper operation.
For proper operation, look for at least 3 bars lit solid.
The module must be registered to transmit messages
to AlarmNet and your central station.

insulation or aluminum siding and other large metal
If a consistent two
