Dear Valued Customer,

Preparing for the CellBounce
™

End of
Support


We want to
remind

you of an important update regarding your customers’
CellBounce devices (CB34UDRES01A).
As we
previously communicated,
AT&T
has announced that, as of May 1, 2025, they will no longer support CellBounce
devices on their network. The information below will help you prepare for the
end
of support
.


For clarity, any AlarmNet device designated as “GSM”, “3G”, or “4G” must be
replaced by this date, as functionality will be impacted and life safety signals will
not be communicated.


You can view your accounts via AlarmNet 360® (
www.AlarmNet360.com
).

How to identify your Cell
B
ounce devices:


1.

Login to AlarmNet 360 via the web

2.

From the navigation menu, select "Tools" > "AN360 Reporting"

3.

Then select the "Daily CellBounce Report"


To help your customers avoid interruptions, we recommend the following corrective actions:

•

For CellBounce connected to Vista panels:

Replace the CellBounce device with a compatible
LTE communicator.

•

For CellBounce connected to Lynx or Lyric panels:

Upgrade your customer’s system to the
ProSeries
-
AIO.

If not addressed, your impacted accounts will experience the following conditions as of May 1,
2025.


Communication Failures

•

Communication failures may occur depending on the programmed supervision rate of the account
(typically Daily or Monthly). A communication failure message will be generated to the Central Station if
that supervision period has expired, and the device has n
ot checked in during that time.

•

You may also have accounts that are programmed as unsupervised. For those accounts a
communication failure
will not be generated.


Communication Failure Reminders

Reminders are generated to the Central Station based on the programmed supervision rate of the
account:

•

“Daily Supervision”, reminders are generated daily

•

“Monthly Supervision”, reminders are generated weekly

•

“Unsupervised”,
will not generate any reminders

•

For all other supervision levels, reminders are generated daily


Panel/Keypad Faults

•

Your customers may also experience a local audible annunciation and fault condition that would be
displayed on the systems keypad or touch screen. That local annunciation is dependent on how the
system is programmed. Typically, that programming field is ca
lled “Cell Fault Time” and is defaulted to
“60 minutes”. The fault will occur if the communicator can no longer communicate with the cellular
network and the 60
-
minute time period has expired.

•

You can confirm your accounts’ supervision rates as well
the “Cell fault time” settings by accessing
AlarmNet 360 and reviewing those programmed parameters from the menu “Devices/Programming”.

Dual
-
Path Communicators (IP and 3G/4G)

Prior to May 1, 2025
,

any Dual
-
Path account should be reprogrammed to ensure that the IP path is the
primary and sole
communication path, providing there are no agency type restrictions. When IP is
connected and active, those accounts will continue to communicate via IP. You are responsible for
changing those accounts to IP only which can be accomplished through AlarmNet
360 Device
Programming, by changing the communication path to “IP only”. If this is not done, your customer may
experience the local fault

conditions and corresponding audible annunciations as described previously.
These accounts will no longer have dual path communication after May 1, 2025.Your communicator
upgrade to LTE for those accounts can occur after the CellBounce
end of support

date.

Account Cancellations

Due to the timing and ambiguities of the specific shutdown processes around the sunset,
Resideo will
not be unilaterally cancelling any accounts after the Cell
B
ounce
end of support

and you will
remain liable for all account fees
. The central station will be responsible for cancelling GSM/3G/4G
accounts through AlarmNet 360 (“Accounts / Cancel”). If you still plan to upgrade a GSM/3G/4G device
to LTE in the future, you may choose to keep the account active until the LTE upgrade ta
kes place.
This will allow you to retain existing programming options, and Total Connect user configurations, which
will make the transition to LTE easier. Please note that any GSM/3G/4G account that remains active
will continue to be billed at their norma
l rates. Dual Path communicators that currently use both cell and
IP/Wi
-
Fi will also continue to be billed at their normal rates.
