1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The fire detection control panels C402 and C404 control respectively up to 2 and 4 independent zones with a
maximum of 32 devices per zone. Each circuit is considered as an zone and can be included or excluded via a keypad
command.
The control panel has two outputs: a general alarm siren output, which is armed with at least one zone in alarm, and
another one for general fault, which is armed when a fault condition is verified on the control panel or in the zone.
The general alarm siren output can be included or excluded via the keypad. Further relay outputs are available on the
optional relay card.
It is possible, independently for each zone, to decide whether to notify the alarm condition when one (single knock) or
more (double knock) devices detect an alarm.

These personnel must have access to the appropriate documentation, especially this manual. Not qualified personnel
must not operate on the control panel for any reason. Furthermore, it is necessary to disconnect the control panel from
the mains in advance.
2.1.2 Power supply disconnecting device
Since the control panel must be installed in a fixed way, a power supply disconnecting device with manual command is
required by the installation standards. This device must be installed by qualified personnel in an electrical cabinet that
may contain other devices if necessary; therefore, it must be properly identified.
2.1.3 Batteries
The control panel has an internal power source with two lead sealed batteries.
WARNING!
If the batteries are replaced with inappropriate ones, there is danger of explosion or fire.
Dispose of worn batteries by following the relevant instructions.
The batteries may cause risk of electric shock or burns due to high current of short circuit. It is necessary to observe
the following precautions:
•Remove watches, rings, bracelets or any other metallic object.
•Use objects with insulated handles.
•Do not place metallic tools or objects on the batteries.
RISK OF ELECTRIC SHOCK!
•Do not try to modify the wiring or connectors of the batteries. These operations can cause injuries.
2.1.4 Battery disposal
The lead batteries contain harmful substances!
When the battery life cycle finishes, they must not be disposed of with ordinary waste. Batteries must be taken to an
authorized waste recycling and disposal centre.

5 SIGNALLING OUTPUTS AND RELAYS
5.1 SIREN OUTPUT
The control panel has a supervised siren output for the signalling of the alarm condition. This output is controlled
permanently by the control panel and, in case of interruption or short circuit in the connection with the siren, the control
panel generates a fault signal. The siren output, when the control panel is in an alarm condition, can be deactivated
and reactivated again.
The siren output can be excluded from its operation; in this condition, the output is neither activated nor supervised.
5.2 FAULT RELAY
The control panel is equipped with an SPDT form C – dry contact relay to signal the general fault condition managed
as follows:
•Control panel ON without any fault event: energised relay
•Control panel ON with at least one fault event: non-energised relay
•Control panel OFF: non-energised relay
The silkscreen in the card is related to the non-energised relay condition.
5.3 OPTIONAL RELAY CARD
The optional modules MR402 and MR404 are equipped with 2 or 4 outputs respectively, with an SPDT form C – dry
contact relay that makes it possible to differentiate among the signals from alarms that come from each zone.
The relay associated to a zone is activated when:
•The zone goes to alarm condition because of an alarm coming from one device
(zone programmed in single knock mode)
•The zone goes to alarm condition because of an alarm coming from two or more devices
(zone programmed in double knock mode)
On the optional modules MR402 and MR404, there is also an SPDT form C – dry contact relay output that signals an
alarm condition of any zone of the control panel.

Installation-Programming C402-C404 17
6 ACCESS LEVEL
Access levels are defined in the control panel for the protection from unwanted operation performed by non-authorised
personnel.
The access levels, as per the EN54-2: 1997 + A1: 2006 standard, are described below:
•Access level 1: it can be used by anybody who has a general responsibility of supervising. This level is active
when the access password has not been inserted and the indicator is turned OFF.
•Access level 2: it can be used by personnel having a specific responsibility in the area of security and properly
trained and authorized to operate the control panel in any of the following conditions: idle, alarm, fault and with
active exclusions. This level is active when the password has been inserted and the indicator is turned ON.
•Access level 3: it can be used by personnel properly trained and authorized for maintenance and reconfiguration
of specific data. In order to get access to the internal parts of the control panel, a proper device (screwdriver) is
required.
•Access level 4: it can be used by personnel properly trained and authorized by the manufacturer to repair the
control panel and modify its configuration. In order to get access to the internal parts of the control panel and
modify its configuration, a proper device (screwdriver) and an external equipment (not provided with the control
panel) are required.
6.1 ACCESS LEVEL 1
When the access level 1 is active in the control panel, it is possible to perform the following operations:
Indicator lights test
The key starts the test of the indicator lights and the buzzer, in order to verify their correct operation.
Acknowledge and buzzer silencing
The key allows the silencing of the buzzer. The silencing of the buzzer acts on all the alarms or active faults when
the key is pressed. This deactivates the buzzer. When new alarms or faults are verified, the buzzer will be activated
again.
When the indicator is off, the control panel is at access level 1; when the control panel is power supplied, access
level 1 is activated.

18 Installation-Programming C402-C404
6.2 ACCESS LEVEL 2
To enter the access level 2, press the key and keep it pressed until the indicator flashes, then press the keys
1÷4 to enter the password. If a valid password is entered, the indicator will be ON permanently, indicating that the
control panel is in access level 2 (preset password at the factory: 1,1,1,1).
When access level 2 is active in the control panel, it is possible to perform the following operations:
Siren output silencing and rearm
When the control panel is in an alarm condition with the siren output armed; by pressing the key the siren is
silenced; when pressing the key again the output is rearmed. If the siren is silenced, when an alarm condition from
another zone is detected, the siren output is rearmed.
The indicator light flashes when the siren output is silenced.
Faults/alarms reset
The key cancels all the active fault and alarm conditions, placing the control panel in an idle condition. Also,
the key deactivates the siren output.
Siren output inclusion/exclusion
To exclude the siren output, press the key and keep it pressed until the indicator turns on. To include the siren
output, press the key and keep it pressed until the indicator turns off.
The status of inclusion/exclusion is saved in the non-volatile memory; in case the control panel is turned off, when
turning it on again the status is restored.
Zones inclusion/exclusion
To include or exclude the operation of every single zone, press the corresponding numerical key. When a zone is
excluded from operation, the corresponding indicator is on. The status of inclusion/exclusion is saved in the non-
volatile memory; in case the control panel is turned off, when turning it on again the status is restored.
When a zone is excluded, the corresponding detection circuit is not power supplied.
When the intervention is completed, it is recommended to restore the control panel to its regular condition of operation
with access level 1, pressing the key and keeping it pressed until the indicator turns off.

7 PROGRAMMING
7.1 ACCESS TO PROGRAMMING
To access the programming, turn the control panel off, remove the front panel, disconnect the positive terminal of the
batteries and insert the JP3 jumper on the main card. Then, power supply the control panel and wait for the flashing of
indicator lights , and .
When the control panel is in the programming phase, it cannot control the detection circuits; during this phase the
control panel displays the operation modes of the zone and the password code to access level 2.
To complete the programming phase, it is necessary, with the control panel off, to remove the JP3 jumper, reconnect
the positive terminal of the batteries and close the container.
7.2 ZONE OPERATING MODE
Single knock mode
When a zone is programmed in single knock mode and the control panel is in an idle condition, when there is a
passage in alarm of a device, the control panel moves to the fire alarm condition by arming the internal buzzer, the
siren output and the optional module relays of cumulative alarm and zone.
Double knock mode
When a zone is programmed in double knock mode and the control panel is in an idle condition, when there is a
passage in alarm of a device, the control panel moves to the fire alarm condition by arming the internal buzzer and the
relays of cumulative alarm and the optional module. If another device of the same zone goes into the alarm condition,
the control panel arms the siren output and the corresponding relay of zone present in the optional module.
The control panel has, as set up in the factory, the double knock mode active in any zone.
The double knock mode is an option with requirements as per EN54-2: 1997 + A1: 2006 par. 7.12 - “Type B
dependency”.
7.2.1 Display of the zone operating mode
When the control panel is in the programming phase, the operating mode of every single zone is reported by its zone
alarm indicator:
Zone indicator off single knock mode
Zone indicator on double knock mode
7.2.2 Programming of the zone operating mode
The operating mode of every single zone can be changed when the control panel is in the programming phase; in this
condition press the numerical keys of any zone. Every time the key is pressed, the operating mode of the zone
switches between single and double knock with the immediate display of the selected mode on the corresponding
zone indicator.
The operating mode of every zone is saved in the non-volatile memory of the control panel. The information in this
memory cannot be lost when the control panel is not power supplied.

7.3 LEVEL 2 PASSWORD
7.3.1 Password display
When the control panel is in the programming phase, the password made of 4 numbers is displayed on the fault and
exclusion indicators above the keys 1 – 4. The first number of the password is displayed by the indicators and
above the key 1, while the last number is displayed by the indicators and above the key 4.
The indicators and can assume the following states, therefore providing the numerical indication of the
password:
Indicator Indicator Numerical value
Off Off 1
Off On 2
On Off 3
On On 4
7.3.2 Password programming
The password of the control panel can be changed when the control panel is in the programming phase; in this
condition press the key until the indicator flashes and all the indicators , and are on. Enter the new
password by pressing the keys 1÷4: every time a key is pressed, the indicator turns off, while the corresponding
indicators and display the sequence of the number/key pressed. After entering all the four numbers, the control
panel saves the password in the non-volatile memory, the indicator turns off and displays, on the indicators above
the 1 – 4 keys, the password just programmed.
The control panel has a default password from the factory reported in the table below. It is recommended to change
the password and write it down in the appropriate “user” spaces.
