ENGLISH
The IT-400 is an elaborate hardwire control panel with 4+3 zones divided as follows:
The first 4 burglary zones are programmable and may be configured as Day, Night, normally
closed (N.C.) or balanced. Each of these zones has automatic by-pass feature which goes
into effect after 4 alarm cycles. In addition Zone 1 and Zone 2 can be configured as delayed
or immediate.
The remaining 3 zones (fire, panic and sabotage) are not programmable and always
active.
The control panels of the IT-400 series may be armed by means of a mechanical key (IT-400),
an electronic key (IT-400 K) or keypad (IT-400 D). Remote arming key is optional.
The creation of a group of zones that function in Day or Night permits you to rapidly arm the
control panel without modifying the way the panel has been programmed.
For IT-400 K only, unauthorized attempts to arm the control panel will activate the anti
-sabotage zone which will block the use of the electronic key and at the same time trigger the
alarm.
The extreme flexibility of the different programming methods allows the end user to
personalize the installation based on his needs.
Other Characteristics
Day/Night arming
Programmable relay alarm outputs
Separate relay alarm outputs for internal sirens
Remote indication for unit ON

18.0. RESET TO FACTORY CODE (IT-400 K / IT-400 D )
This is an emergency procedure to be used, for example, in the case that the owner has lost
all the electronic keys (IT-400 K) or forgot the access code (IT-400 D).
1) Open the cover of the control panel and disconnect all power (both 230 Vac and 12 V
battery supply).
Note: This will provoke a TAMPER ALARM!
2) Put to ON dip 1 of dip-switch A.
3) Re-connect the power to the control panel. The LEDs “ON” and “NIGHT” will flash to
indicate maintenance mode.
4) Remove bridge "J8".
5) (IT-400K only) - Insert the Master key and wait until the LEDs “ON”, “DAY” and “NIGHT”
fast flash twice to indicate that the master key has been memorized.
If this does not happens, repeat points 4) and 5).
6) Insert bridge "J8".
7) Exit from maintenance by putting to OFF dip 1 of dip-switch A.
8) Close the cover.
After following the above procedure all of the electronic key codes memorised in the IT
-400K will be cancelled and the access code programmed by the user in the IT-400 D will
return to the pre-programmed factory code of 123456 and the control panel will auto-
matically set to “DAY” status.
17.0. LOW BATTERY ALERT
 In case of mains failure, the power is supplied by the battery.
When the battery voltage goes below 10.5 V, the control panel will signal the event with the
lighting of the “LOW BATTERY” LED on the panel.
The LED will remain active until the control panel is re-armed to signal "Low battery
memory".
 If “LOW BATTERY” alert continues, check if the mains is present (green “POWER” LED
lit), check the mains fuse and if the battery charger is functioning correctly (+13.8 Vdc on
cables of battery). If all functions correctly, then the battery must be replaced.
Please dispose of faulty batteries in an environmental
friendly manner.
ATTENTION

ENGLISH
For an easy and correct installation follow the steps listed below.
1) Remove the ABS control panel cover
2) Fix the base of the panel to the wall
3) Connect all the sensors and sirens to the control panel
4) Connect the mains 230 Vac power source to the 3 terminals
indicated on the right. Be sure to connect a good ground source
to the centre terminal.
Be careful that the cable being connected is without tension.
5) Program the unit using dip switch A and B (see page 32).
6) Connect the battery using the red and black terminal which indicate the polarity. Red for
positive and black for negative, you will see the “test” LED flashing. This indicates that the
control panel is in Maintenance mode.
7) Re-position and fix the control panel cover.
8) Connect the mains power input wire to a 230 Vac source. It is suggested that this power
source be obtained between the AC power meter and the main circuit breaker. After this is
done the green LED “POWER” will light up.
9) Be sure that the 24 hour anti-sabotage line is closed (red LED - 24 H OFF).
10) Set the panel in “DAY” mode. The control panel will go into disarmed status.
 IT-400 : Rotate the key in “DAY” position
 IT-400 K : Automatically goes to “DAY” status.
 IT-400 D : Automatically goes to “DAY” status.

Procedure for self learning code:
1) Insert the Master key for less than 5 seconds and during the exit time open the front cover
and set switch 1 of dip-switch A in ON position. The LEDs “ON” and “NIGHT” will flash to
indicate maintenance mode.
2) Open the jumper "J8". The LED “ON”, "DAY" and “NIGHT” will light to indicate self learning
of codes. Insert a key in the front panel receptacle and wait for two fast flash of the LEDs
“ON”, "DAY" and “NIGHT”. This confirms that the key code has been read. Insert jumper
"J8" to confirm the memorization of the key.
Repeat the above procedure for all the keys to be memorized.
It is possible to memorize up to 9 keys, including the Master key.
NOTE: If you try to memorize a previously memorized key the panel will not use a new
location of memory, only the flashing of LED “ON”, "DAY" and “NIGHT” will happen.
If all the 9 memory locations have been occupied, the panel will not accept new
keys. In this case the master key (as explained in paragraph 18.0.) and all the
available keys must be re-programmed as described above.
The control panel can learn up to 9 different
electronic key codes.
The control panel is supplied with factory programmed code of “123456”.
This code can be modified using the following procedure:
 With the control panel in "DAY" mode, digit:
“# existing code # new code #”
 This code may be made-up from a minimum of 1 and a maximum of 6 digits (from numbers
between 0 and 9).
 If you forget the user code, it is possible to “Reset to factory code” (see paragraph 18.0.).
The panel is supplied with 2 keys already memorized. One of these is
the master key, which is the only key that allows you to go into
maintenance mode and program other keys in the memory. If the
Master key is lost the “reset to factory defaults” procedure must be done (see paragraph 18.0.).

ATTENTION
For the alarm to be triggered the line must remain open for more then 0,3 seconds.
6.0. ZONE DESCRIPTION
The series IT-400 control panels (It-400, IT-400 K, IT-400 D) have 7 zones in total of which L1
 L4 are burglary alarm zones and L6, L7, L8 are Fire, panic and anti-sabotage.
 All 7 zones (Terminals 18 to 23 and 25 to 29) can be programmed through the dip-switch
as normally closed (NC) or balanced with end of line resistance 4.7 K ohm.
 The first 2 burglary zones, L1  L2 (Terminals 18,19,20) may be programmed either as
delayed or immediate, while L3
 L4 (Terminals 21,22,23) are only immediate.
 The remaining 3 zones, anti-sabotage, fire and hold-up (Terminals 23,24,25,26,27,28,29)
are always active.
ATTENTION
If the control panel is programmed using end of line resistors you
must place a resistor of 4.7 K ohm in series with the sensors
installed. If the value of this resistor is changed (for example short
circuit), the panel will trigger an alarm.
Note the location of 4K7
end of line resistor (see
the figure on the right).

The control panel is protected against attempts to insert a false electronic key.
 If a person inserts a wrong key 10 times, the internal siren relay (Terminals 9,10,11) and
external siren relay (Terminals 12,13,14,15,16,17) will be triggered for the alarm time
programmed.
7.3. ELECTRONIC KEY SABOTAGE
(IT-400 K only)
The IT-400 K may be armed and disarmed through the
electronic key situated on the front panel or with a remote
electronic key (optional). The control panel is supplied
with 2 electronic keys already coded .
The control panel can self learn and memorize up to 8
different codes. Available upon request there are also
receptacles for electronic key series Magic and Living.
On the receptacle there are 3 LEDs that signal control
panel full armed “On mode”, partially armed “Night mode”
and “DAY mode” (see figure on the right).
 LED "Control panel armed ON"(Red)
Has the same functions as LED “ON” on the panel.
When the electronic key is inserted, the LED emits the
following signal:
1) Lit during exit time, after exit time has expired
flashes until panel is disarmed.
 LED "Control panel armed Night mode” (Red)
Has the same functions as LED “NIGHT” on the panel.
When the electronic key is inserted, the LED emits the following signal:
1) The LED will flash at the end of the exit time until panel is disarmed.
 LED "DAY mode and Alarm Memory" (Green)
1) When control panel is in "DAY" mode, the LED flashes.
2) This LED will light during the exit time if one of the 7 zones is triggered.
3) After an alarm trigger, this LED will light and remain lit until the control panel is
disarmed and re-armed. This is indication of alarm memory.
7.2. REMOTE RECEPTACLE INSTALLATION
To allow arming of the control panel from more then one
remote position it is necessary to wire up to terminals
33, 34, 35, 36 and 37 of the IT-400 K to the terminals on
the back side of the receptacle as shown in the figure on
the right.

8.0. MECHANICAL SWITCH LOCK KEY (remote)
The IT-400 and IT-400 D may be remote armed/disarmed by means of a switch lock
connected to terminals 33 and 34.
 Using a remote switch lock only total arming/disarming is possible (ON position and
Day position). Night arming is not possible.
 If the control panel has been armed with a remote mechanical switch lock (Terminals
33 and 34 open), it is possible for the control panel to be disarmed by means of the
front panel key (or numeric code for IT-400 D) or the remote switch lock.
 If the control panel has been armed with the front panel key or by numeric code (IT
-400 D) and you attempt to change the status with the remote switch lock, the con-
trol panel will not respond anymore to the remote switch lock.
9.0. MAINTENANCE MODE
With the control panel in this mode it is possible to:
1) Open the control panel without triggering an alarm
2) Re-set to factory codes (IT-400 K and IT-400 D only)
3) Enter into the
programming mode
 To enter into Maintenance
With cover open: Set switch 1 of dip switch A to ON for programming. The LED “ON”
and “NIGHT” will flash to indicate maintenance mode.
With cover closed (panel already installed):Set the panel in ON mode (with the master
key in IT-400 K) and during the exit time open the cover and set
switch 1 of dip-switch A to ON for programming. The LED “ON” and
“NIGHT” will flash to indicate maintenance mode.
 To exit Maintenance mode
