Use of radio devices close to electronic equipment may
be inadvisable:
Do not install CT3MA close to medical devices like pace-
makers or hearing aids. CT3MA could interfere with the
regular operation of these devices.
Switch off CT3MA on planes. Make sure it cannot be
switched back on accidentally.
Do not install CT3MA near oil stations, fuel deposits,
chemical plants or explosive sites since CT3MA could
interfere with the operation of technical equipment.
CT3MA could generate interference if used near TVs,
radios or PCs.
In order to prevent possible damages, only use accesso-
ries tested and certied as compatible with CT3MA
Information contained in this manual can be modied

Safety Information
The use of CT3MA in life support systems or components is not al-
lowed and, if required, it must be authorised beforehand in writing.
Life support systems are components or systems used to assist ar-
ticially the human body in its functions. In case of faulty operation,
these could cause injury to patients.
No complex hardware or software system can be considered perfect.
Faults can occur in systems of any kind.
To prevent damages to things and injuries to persons, it is up to the
designer to devise redundant protection methods, suitable for the
risk related to use.
Every CT3MA unit is submitted to complete functional testing.
Specications are based on the characterisation of the tested sample
unit and do not refer to measurements taken on each single manu-
factured unit.

Product description
CT3MA is a GSM terminal suitable for remote control of heating sy-
stems, specially when no xed telephone line is provided.
CT3MA also enables to control two remote inputs and one output.
Communication is implemented via a mobile phone and the GSM
modem of the device using SMS messages.
CT3MA characteristics, functions and interfaces are described on
next pages.

Product description
Operation
When CT3MA is connected to a Fantini Cosmi chronostat model
C46A, C55-56, C51-52-53-54, C75CT-76CT, CH15X, via SMS mes-
sages it enables to read the chronostat status (ambient temperature
measured, programme set, etc.) to modify the set programme and to
change certain thermoregulation parameters (only for CH15X).
CT3MA can automatically send a SMS message to the phone num-
ber stored inside it when an alarm conditions occurs (due to contact
clo-sing/opening).
NOTE: different alarms can be controlled by setting them parallel
with each other.
External antenna
Connect dual band antenna (GSM900/1800) to RF interface avail-
able on CT3MAA model. Connection is obtained by connecting the
antenna to the SMA/F connector set on the top of the device.
Immunity against interference
Provide suitable protections against fast transients if the cable is lon-
ger than 3m

If xed installation with wiring under chase is required or if the cable
provided with jack plug is short, use another cable 3 x 0.5 mm2 with
20 m max. length. Connect one end to terminals 1 -2 - 3 of the ad-
ditional module and weld the jack plug as shown in the diagram. In
case of xed installation only: open the knockdown area on the base
to friendly connect cables to terminal board.

CT3MA can be connected to two external clean contacts.
Contacts power supply is provided by CT3MA.
Use mechanical or electromechanical contacts suitable for use with
40Vmin / 20mAmin dc.
Polarity
When using electronic switches, terminals In-1 and In-2 are positive
terminals whereas GND is the reference.
Anti-rebound
To prevent false operations, contacts ate considered closed or open
only after 1 second of stable condition.
Connection
Immunity against interference
The cable shall not be longer than 3 m.

18

Operating state / LED
The LED (F, see page 10), on the front panel shows the different
CT3MA operating states:
Operating state LED
- Not powered OFF
- Network search ON (fast ashing)*
- Standby (recorded in the
network)
SLOW FLASHING
* Network search usually requires a few seconds after power on.
If the led stays on ashing check for proper SIM card tting.
The LEDs (G - H - I) on the front panel in addition to show INPUT and
OUTPUT status indications show also the following CT3MA operat-
ing states:
Operating state LED
-No SIM card Fast ashing
- Field intensity measurement G+H+I according to eld
intensity#
#Field intensity is measured only at power on and during the rst
seven minutes after device recording on the GSM network. Field
measurement can be stopped by sending whatever command via
SMS message or waiting for seven minutes. G, H and I LEDs indi-
cate eld intensity as follows:
Very low intensity: G Off, H Off and I Off
Low intensity: G On ashing, H Off and I Off
Good intensity: G On ashing, H On ashing and I Off
High intensity: G On ashing, H On ashing and I On ashing
If GSM signal intensity level is lower than -109dBm, CT3MA may not
work properly.

Remote management
Using the SIM card
Before using the SIM card, we recommend that you test it in a mobile
phone to see if it’s working.
Particularly:
- Check that no PIN code has been set. If so, exclude it.
- Check the remaining credit
- Send a SMS message and check if it arrives.
Switching oncensione
After switching the device on, SMS messages not yet delivered or
sent during the rst instants of operation will be cancelled without
being performed.
Standby
In Standby status, CT3MA is recorded in the GSM network and it is
ready to send and to receive SMS messages.
Synchronisation with the GSM network is obtained through short and
continuous transmissions.
CT3MA consumption in this status depends on whether the network
is avai-lable or not.
Sending an alarm
When input contacts are closed, the corresponding LEDs (G and H)
will turn on and CT3MA will send to stored numbers the following
message: “Input1 ON!” or “Input2 ON!”.
Alarm sending condition can however be set as follows:
Send alarm at contact closing
Send alarm at contact opening
Send alarm at both contact opening and closing
NOTE: Alarm is only sent if there is at least one mobile phone num-
ber stored, to which the alarm message can be sent. To cancel a
stored phone number, to customize the alarm message or to select
the alarm sending condition, follow the procedure described in para-
graph “ Alarm commands” on page 22.
