Introduction
The CM746B 4G CAT 1 radio module allows you to inter-
face compatible security control panels to the CAT 1 cellu-
lar network providing a high reliability primary or backup
reporting path.
The CAT 1 network is widely supported by all carriers
however if the unit is being installed in a remote location,
you should insure the carrier you are using has sufficient
coverage (signal) for reliable performance. SIM’s must be
on a plan that includes a data allowance.
The unit is designed to plug onto the main control panel
PCB using the supplied plastic standoffs.

Getting Started
There are four main steps required to configure the
CM746B for reporting to the control room. The instruc-
tions assume that you already have purchased a SIM card
and that the card has been charged with credit and acti-
vated on the network if necessary.
1. Install the SIM card into the lower card socket. (SIM1)
2. Install the CM746B hardware on the control panel.
3. Install the antenna.
4. Configure the module’s features and parameters.
5. Configure the control panel for reporting.
Step 1 - Installing the Radio Module
Ensure that the panel is powered off before proceeding.
Plug the 3 short plastic standoffs into the module and
then plug it onto the Expansion Port header pins on the
panel as shown in. Install the SIM card into the SIM 1 card
position.

Step 2 - Installing the Antenna
Remove the knockout in the top of the cabinet and pass
the antenna lead through the hole ensuring the antenna
is on the outside of the cabinet. Screw the lead to the
socket on the radio module before powering the panel.
Step 3 - Configuring The Module
Once powered the radio will attempt to connect to the
network. This may take up to ten minutes to complete.
During this time the online indicator on the module will
be on solid. Once the radio has registered the online indi-
cator will begin to flash and the signal strength indicators
will show the current signal condition.
Experiment with the position of the antenna to find the
best signal strength before fixing it in place.
Step 4 - Configuring The Panel Reporting
Reporting configuration will vary depending on the
required options and whether or not the module is to be
used as the primary or secondary reporting route.
Configure the required reporting formats in MENU 5-4-0
and 5-4-1. The system can be configured to report to the
base station in Conettix IP, SIA IP, CSV or to selected phone
numbers via SMS.
All reporting scenarios are configured by varying the pro-
gramming of the reporting format and reporting routes
configurations options.
Module Indicators
The module includes 7 led indicators which are used to
show status and signal strength. See table below.
Module Indicators
Indicator Meaning

RX Module Receiving Data
Online ON Steady = Not Registered On Network
Pulsing = Registered On Network
Signal 1 Signal strength indicators show relative
signal level at the radio. Signal indicator 1
on indicates weak signal and all 4 indicators
on indicates stronger signal strength.

Supported Reporting Formats
Version 2.51.04 or higher of the Solution 6000 panel firm-
ware is required to support the CM746B.
The following reporting formats are currently supported
by the module.
SMS Format via GSM
CSV-IP Format via GPRS
Conettix Format via GPRS
SIA IP Format via GPRS
MyAlarm Format via GPRS
There is no support in the 4G module for Contact ID (CID)
over GSM.
CLI Trigger Output Control
The CLI trigger tables in MENU 6-5-5-0 and 6-5-6-1 can be
used to store a list of telephone numbers that can trigger
an output on the control panel. If you call the GSM unit
from a telephone number that matches a number in the
CLI list then the appropriate output will be operated.
An output needs to be programmed with an event type of
CLI Trigger and event assignment of 1 or 2 depending on
which table is to be checked.
Simply call the GSM unit from a telephone number that is
programmed in the CLI trigger list to activate the output.
Module Status
MENU 6-5-0 can be used to obtain various information on
the radio module. The following information is currently
available.
1) Connected Network
2) Signal Strength in dB
3) IMEI Number
4) Radio Firmware Revision
5) SIM Card Present
SMS Remote Control
The SMS control option in MENU 6-5-6 allows you to
program up to 10 telephone numbers that are allowed to
send SMS commands to the GSM unit.
Numerous commands can be sent to the panel using the
SMS control functions including arming/disarming areas,
controlling outputs and doors or checking system status.
The panel can also be requested to send a confirmation
SMS if required.
The control messages must be sent to the SIM phone
number.
The SMS Control phrase table shows the correct method
for constructing the SMS messages. Note there are no
spaces between the fields only commas as shown.
Smart Device Apps
Smart device apps are available to enhance alarm report-
ing and provide real time control of system areas, outputs
and doors etc. More information can be found in the app
stores or on the MyAlarm web site at www.myalarm.com.

SIM Balance Recharge Reminder Function
In Solution 6000 version 2.20 firmware, a new SIM ex-
pire parameter can be added to the to the SIMBAL setup
command when using the GSM module with a pre-paid
SIM card. When configured the control panel will send a
reminder to the designated SIM owner prompting them
to recharge the SIM before it expires.
The SIM Balance string would include the following pa-
rameters including the new optional reminder in weeks
(01 to 52 weeks).
The MyAlarm SMS Control smart device app has been
updated to include support for this new feature. For more
information refer to the example below.
User Code
This field is used to enter your PIN (eg. 2580).
Command Header
The command header field is fixed - SIMBAL.
Access Number
Enter the communication provider’s access number for
SIM card balance enquiries.
• Optus = 9999
• Vodafone = 1555 / 1512
• Telstra = #100#
• Virgin = 225
Text
Enter the text required by the communication providers
to obtain your SIM card balance (Max = 16 characters). In
Australia, examples may change and include:
• Optus = Balance
• Vodafone = Blank Message
• Telstra = Voice Call
• Virgin = Bal
Preamble
Enter text to search for the credit remaining on your SIM
card (eg. if Vodafone Australia displays‘U’ve Remaining:
365 day: $35.53 Exp: 09/11/2015’ enter ‘Day:’ as the pream-
ble).
Minimum Amount
Enter the minimum balance to filter GSM module SIM card
balance enquiries. This allows the GSM module to only
forward an SMS balance alert message to your mobile
telephone when the SIM card balance falls below the
minimum amount set here.
Days
This parameter sets how often the GSM module will
automatically request a SIM card balance. This can be set
between 001 and 255 days / 000 = disabled.
Mobile
This parameter allows you to program which mobile
telephone number the GSM module will forward the SIM
card balance enquiry of the GSM module to.
Expire Reminder
Enter the number of weeks for the GSM module to remind
you to recharge your GSM SIM card (01 to 99 weeks / 00 =
disabled).
Example
The example below is requesting a SIM Balance of the SIM
card connected to the Vodafone network (Australia) with a
reminder that the credit available on the SIM card requires
a recharge in 25 weeks using a 180 day prepaid SIM card.
The SIMBAL requests a balance enquiry every two days
when the balance falls below $20.00.
SIMBAL,2580,1555,Day,$20.00,002,0414123456,25
After 25 weeks, the GSM module will send the following
SMS, ‘SIM is about to expire please recharge immediately’.
Information in this example is correct at time of print-
ing. Check with your telco carrier as these options may
change.
