Overview The ITP F22 1 is a device capable of turning on and off at any distance one or two electric
appliances thus allowing to control systems like burners, air-conditioners, small irrigation plants
through the use of the telephone public line PSTN (Public Switched Telephone Network).
The interface answers the incoming call after a number of rings set by the user and is only activated
when the internal four digits secret code exactly matches the one composed by the user on the
telephone keyboard.
The interface also features two input channels, thus allowing a remote feedback of the state of a
certain appliance (i.e. if it is on or off) or the state of a voltage free contact of a sensor (like a door or
gate sensor, to know if they are open or closed). The device features an internal digital nonvolatile
memory so that it can ’remember’ its state even in case of a power failure and restore the correct
operating state as soon as the power returns. Two pushbuttons located on the interface front panel
can be used to change the outputs state as well as to show the input state.
In case the interface is wired on the same line as that of a fax machine, a special option can be
activated: when this is activated the interface is instructed to answer after it receives two calls with
one ring each. With this ’trick’ the interface can answer the call before the fax machine does. On the
front panel are also located two red indicators, used to show the inputs or the outputs actual state
(see further) and one green indicator, whose purpose is to show the presence of power, an incoming
call or the state of the communication established.
The device can be easily mounted on a wall with the screws and plastic shells supplied in the
package.
Operation The telephone interface ITP F22 1 answers a phone call after 2 rings (factory setting) or after a
number of rings set by the user. The interface gives for this an acoustic feedback with a short music
jingle. When the four digits secret code is composed by the user on the telephone keyboard, the
interface plays a little longer music jingle thus giving access to all the available configuration and
control commands.
All commands are described in the following parameters; in case of an error in inputing a command
sequence, the operation can be aborted by pressing *so that the sequence can be composed again.
In case for 5 consequent times the secret code is composed in a wrong way, the interface
automatically terminates the phone call.
The same happens in case for at least 30 seconds no command is issued by the user. Anyway it is
always possible to make a new call. This telephone interface can be driven also by a mobile phone
or by another device (computer or alarm system), provided it can issue the correct multi-frequency
tones (DTMF).
CH1 and CH2 Outputs
Control When the sequence *01 is composed on the keyboard, the CH1 output relay control mode is
initiated. The interface replies with a deep single note sound in case the relay is inactive or with a
high double note sound in case it is active. If the key 0is pressed the relay turns off meanwhile it is
turned on when a 1is pressed.
Each time the interface receives a command it also replies with the new state of the relay.
Entering the command *02 from the telephone keyboard the CH2 output relay control mode is
initiated, which is then carried out as for channel CH1.
IN1 and IN2 Inputs
Control When the sequence *11 is entered from the telephone keyboard an interrogation on the IN1 input
state is made. The interface then replies either with a deep single note sound when the input contact
is open or with a high doublenote sound when it is closed.
When the sequence *12 is entered the IN2 input state is checked with exactly the same way of
operation.
Setting the Number of
Rings at the Answer The command *7 “Number of rings” # sets the number of rings the interface waits before
answering the incoming phone call. This number can be set from 1 to 10 by simply pressing the
relevant digit on the phone keyboard, except for 10 which is set by pressing the digit.
Examples:
If *74# is composed the interface answers after 4 rings.
If *70# is composed the interface answers after 10 rings.
If the command sequence was correct the interface gives a successful feedback with a dual-tone
sound; in case of failure instead it gives a single-tone sound. In case of success the setting of
number of rings is stored in memory and maintained even in case of absence of power.
Note: The factory setting for this parameter is 2 rings.

Fax Option The fax option allows to wire the telephone interface on the same telephone line on which is plugged
a fax device or any other device capable of an automatic answer to the incoming calls. The fax
option, when enabled, operates in a way that the telephone interface answers the phone call before
the fax attempts to do the same thing. The interface will then be able to answer the incoming call in
two different ways: either after the set number of rings or after two consequent calls each only one
ring long.
Let’s suppose that the fax machine is answering after 3 rings: the interface will then be configured for
answering after a greater number of rings and the fax option will be enabled. In this way all normal
incoming calls will be correctly received by the fax machine.
On the other hand in case the user wants to communicate with the telephone interface without
interference with the fax machine, he will make a phone call and then, after only one ring, hang up
the line. After about 10 seconds (but within 30 seconds) he will make a new call: this time the
interface will answer the incoming call after the first ring, thus anticipating the fax machine.
With the sequence *80# the fax option is disabled, meanwhile with the sequence *81# the option is
enabled. If the command has been correctly composed the interface replies with a dual-tone as a
positive feedback.
Factory setting for this option is for the fax option disabled.
Setting the Secret Code The secret code needed to access the interface can be modified by the user in any moment and is
stored and held in the device even in case of absence of power.
A new secret code (4 numeric digits) can be set by composing on the keyboard the sequence
*9# “new code” # “new code” #. The code must therefore composed twice in order to avoid errors
in the sequence input procedure.
As an example, if the user wants to set as new code the number 5678 the sequence to be composed
is: *9# 5678 # 5678 #.
If the command sequence was correct the interface gives a successful feedback with a dual-tone
sound and stores in its memory the new code; in case of failure instead it gives a single-tone sound
and the old code remains not modified.
End of Call Command When the sequence *0# is composed the communication is terminated. Anyway the interface
provides an automatic end-of-call in case no command is composed in 30 seconds: in this situation a
short sound warns the user when 10 seconds and 5 seconds are left. In no case the overall duration
of the phone call can be longer than 3 minutes: after this time the call is automatically terminated.
Before the call is terminated a short music jingle is played. During the communication with the
interface, a short sound (beep) is issued every time is manually requested a state change in the
inputs or in the outputs.

Reset Button Inside the interface is located a reset button: when this is pressed for a few seconds all parameters
are reset to the factory values. The reset is useful in case the user forgets the secret code. The reset
button can be pressed even without opening the plastic front cover, by using the tip of a proper
screwdriver from the external. In case a reset is performed the interface blinks all the front indicators
three times.
Factory settings are as follows:
- Number of rings at answer: 2
- Fax option: OFF
- Secret code: 1234
LED Indicators On the front panel are located two red LEDs and one green whose purpose is the following:
- Green LED on: the interface is properly powered and is waiting for a phone call on the telephone
line.
- Green LED quickly blinking: the interface is processing a phone call ring on the telephone line.
- Green LED slowly blinking: the interface has answered the phone call and the communication is
going on.
- The red LEDs show the state of the CH1 and CH2 outputs . An LED turned on means that the
relevant output is active meanwhile if the LED is off then the relevant output is inactive.
When both pushbuttons located on the front panel are pressed simultaneously the LEDs show the
state of the inputs instead. An LED turned on means that the relevant input contact is closed
meanwhile a LED turned off means that the relevant input contact is open.
Buttons Operation On the front panel of the interface are located two push buttons: CH1 and CH2. When one of these
buttons is pressed the relevant relay output inverts its state changing from on to off or vice versa,
thus turning on or off the appliance driven by that relay without the need of a phone call.
In case these buttons are pressed together no change of the output state will take place; instead this
will result in showing the state of the IN1 and IN2 inputs state through the front panel indicators.

Mechanical Installation The mechanical installation is carried out by fixing the device on a wall with two screws, taking
advantage of the two holes with 60 mm. of distance between them. When tools are used close to the
screws holes, particular attention must be used in order not to damage the electronics around.
Once the electrical installation has been completed apply again the front plastic cover to close the
case. Place the plastic front cover on the plastic base paying attention in that the holes for the
indicators located on the front cover will fit in the relevant LEDs on the board, then press slightly until
the four plastic side teeth snap.
Wiring Instructions For a correct electrical installation of this telephone interface, follow the wiring diagram sketched
below. At terminals 1..6 the changeover (SPDT) contacts of the output relays are available. These
contacts are voltage free and can be used to drive electrical appliances when wired as described in
the diagram. Terminals 7, 8 e 9 are used by the interface as inputs to acquire a state of an external
contact. Terminal 7 is the common and is internally wired to the power supply ground. At these
terminals can be wired any electrical contact as shown in the diagram.
Note: It is very important to stress that IN1 and IN2 contacts must be voltage free; in other words it
must be only wired to the telephone interface and not to any other electrical appliance.
The wiring to the telephone line is made with the cable supplied with the device. This cable is
provided with standard telephone plugs at each end. One of the ends must be plugged in the female
connector located on the board inside the interface, meanwhile the other must be plugged in the
telephone socket located in the installation site. In case the available telephone socket in not
compatible with the supplied cable a proper adaptor must be used: these adaptors are usually
distributed in electrical shops. In case the telephone interface requires a different wiring to the
telephone line, it is important to keep in mind that the device must be wired in parallel to the existing
line, therefore in parallel with other phone line machines. It is not mandatory to respect the polarity of
the wires to be connected to the telephone line.
The device is powered with 12Vdc: this is made with the supplied external 230V~/12V power supply
whose connector must be plugged in the connector located on the interface board as shown in the
diagram.
