3- DISPLAY AND COMMAND COMPONENTS:
3-1 MAIN DISPLAY/COMMAND PANEL:
The panel has a basic panel which houses all the compulsory signalling and command functions provided for by
standards UNI EN54-2 and 54-4.
Using the panel unit it is also possible to control the auxiliary command and display functions and control the configuration
of the panel (at access level 3).
The panel groups the signals and commands into three logical sections (see Fig.1):
The part on the left (A) houses all the general signals and commands, the central part (B), consisting of an alphanumeric
display and a keyboard, makes it possible to carry out detailed displays and control specific commands (display details,
control zone/line deactivation etc.), and finally the part on the right (C) displays the state of the 32 zones/sectors which
can be controlled from the panel.

FAULT LED
When ON, this indicates there is a fault in the panel and the corresponding output is on (apart from specific
deactivation).
The details on fault occurring are indicated by other LED on the panel and/or alphanumeric display.
LOCK (DEACTIVATION) LED
When ON, this indicates that there is a general state of deactivation in the panel (zones/sounders or another part
deactivated).
The details on deactivation may be displayed by other LED or may be visualized on the display by using the keyboard
when in access level 2.
ALARM LED.
When permanently ON, this indicates that there is a state of alarm in the panel and that the corresponding main
output is on (apart from specific deactivation).
If it flashes on for a long time and off briefly, it indicates that the alarm delay stage is in progress.
When the general alarm LED is ON, it is accompanied by one or more of the corresponding zone LED for the origins
of the alarm. The display also visualizes lines in the state of alarm.
= FAULTS LED; indicate specific panel faults as required by standards UNI EN 54-2 and 54-4, which are:
Power supply fault LED.
When permanently ON, it indicates that the panel power supply or supplementary power supply group (if applicable) is
irregular and that there is one of the following abnormal states:
- mains power lacking for more than 20 minutes
- output voltage of power supply is outside adjustment limits (<22.5V or >29.5V)
- the battery is disconnected or inefficient
- there is a fault on the battery recharge circuit
The flashing LED indicates that the power supply is regular but there has previously been an abnormal state
(memorized signal).
Earth fault LED.
When permanently ON, it indicates that there is a state of low isolation between one of the electric parts on the
system and earth. If it flashes, it indicates that the current state is regular but there has previously been an abnormal
state (memorized signal).
Sounders fault LED.
When permanently ON, it indicates that there is a fault on a balanced line which controls the alarm actuators
(sounders line balance not ok). If it flashes, it indicates that the current state of the line is regular but there has
previously been a state of fault (memorized signal).
System fault LED.
This can indicate different system faults, namely:
a) The panel microprocessor is temporarily or permanently out of control. This type of fault may be caused by strong
interference of an electrostatic nature, by a sudden drop in the power supply voltage or by a physical fault in the
panel card. In the latter case the signal can be stopped but not reset.
This type of fault, unless there is a serious physical card fault, is indicated on the display with one of the following
messages: CPU/MEMORY FAULT, WRONG CPU RESET FAULT.
b) One or more of the input or output concentrator modules are temporarily or permanently out of service. Also in this
case the fault may be caused by strong interference, by a sudden drop in the power supply voltage or by a physical
fault in the concentrator or communication line (short circuit/cut).
This type of fault can also be indicated on the display as INTERFAC.COMUNIC. FAULT and as a fault relative to the
zones linked to the concentrators out of service.
c) The content of the panel memory or firmware of an extension module has been altered.
In this case the display can visualise one of the following messages: WRONG CONFIGUR., MEMORY DATA ERR.,
CPU / MEM. FAULT.

Fuse fault LED.
When ON, this indicates a fault in one of the panel fuses or extension modules.
A fuse fault is indicated on the display with the message: FUSES FAULT.
= Alarm delay LED and button
When the LED is ON, it indicates that the alarm delay function is on. In this situation, the occurrence of conditions for
activating the alarm starts, if set (relative Linesconfigured for delay function), the internal delay count after which the
alarm/sounder outputs are activated. On the contrary, when the LED is off, the alarm is activated immediately.
During the delay count, it is possible to annul the function and activate the alarm immediately by pressing the
IMMEDIATE ALARM key (10).
Press the ON/OFF button when in the 2nd access level (LED 6 on) to activate or deactivate the alarm delay function.
= Sounders locked LED and button
When the LED is ON, it indicates that the general alarm outputs have been deactivated.
Press the ON/OFF button when in the 2nd access level (LED 6 on) to deactivate the alarm outputs or reset them to
operating function.
= Fault locked LED and button
When the LED is ON, it indicates that the general fault output has been deactivated.
Press the ON/OFF button when in the 2nd access level (LED 6 on) to deactivate the output or reset it to operating
function.
= 2nd Level enabled LED
When ON, this indicates that 2nd access level has been activated, thus setting up the commands for reset,
deactivation, test and all the command functions which can be controlled from the keyboard when in level 2.
Level 2 can be activated by typing in the access code (see panel operating functions) or by using a mechanical key
(optional).
= Test enabled LED and button
When permanently ON, this LED indicates that the panel is in test mode (see panel operating functions).
On the contrary, if the LED flashes along with the deactivation LED (1), it indicates that the configuration stage is
activated on the panel.
To activate the test function, press the relative ON/OFF button when in access level 2 and then select the zones in
which the function is to be activated (the test can be activated for individual zones).
The test deactivates automatically by timeout or can be deactivated by pressing the ON/OFF button again.
= Buzzer/alarm off LED and button
The button is always ready (access level 1) and makes it possible to silence the buzzer after it has been activated
following a state of alarm or fault.
The relative LED comes on when an acoustic signal has been stopped.
The panel can be set so that this function also applies to the alarm and fault physical outputs in access level 2.
The function deactivates automatically after a reset.
= Reset button
This makes it possible to reset the memorized alarm/fault conditions but only works in access level 2.
The reset stage is timed and is indicated by the deactivation LED flashing and a message on the display.

If pressed in access level 1or 2 with the alarm delay on, it immediately activates the outputs.
If pressed in access level 2 with the prealarm/alarm outputs stopped, they are reactivated.
3-3 ALPHANUMERIC DISPLAY AND KEYBOARD
(Ref. fig.1, section 3-1)
= 2 line x 16 character alphanumeric display + numerical command keyboard + function keys.
The display visualizes different information relating to the state of the panel and the command operations carried out.
In a standby state (level 2 not enabled and no alarm/fault present), a set message (which can be personalized) is
visualized on the top line of the display e.g.: > ALPHA 16 - 248 EN54 <
The bottom line displays the current time and date.
If a state of prealarm, alarm or fault occurs, the panel buzzer starts sounding and the general and/or zone LED relative to
the fault in course are ON.
At the same time the alphanumeric display shows the details of the fault in course and in the event of more than one state
present, these are displayed cyclically.
Relative to the alarms/faults originating from lines, the display visualizes the associated description on the first line (16
characters set by PC) and the number of the detectors and fault in course on the second line; e.g.: 001 alarm
When level 2 is not active (relative LED off), the keyboard can only be operated by typing in the access code (see
sections further on). When it is active however, different display and command operations can be carried out, in particular:
- Display the state of the lines, display the analog value and intervention thresholds.
- Display the state of the zones/sectors.
- Exclude/activate the Lines and zones.
- Activate/deactivate the test function on the zones.
- Display/modify the state of some special panel resources ( code, timer prog. etc.).
- Display and print the events (if connected to a serial printer).
- Carry out set-up of panel time and date.
- Carry out test of all LED for panel, display and buzzer.
In access level 3 (activated by opening the panel and inserting configuration jumpers) it is possible to display and set the
panel configuration with regard to lines, zones, times and operational options (programming the functional
blocks/programmable outputs and setting the internal timer programmer can only be carried out by PC using the
CFGRAIK application).
When access level 2 is enabled keys 4, 5, 6, 7 have a second function, namely:
- Key 4 (SHOW.) makes it possible to manually display any fault or deactivation conditions in the panel (the next state is
displayed by pressing the key).
If pressed when in a standby state (no state of alarm/fault and no deactivation present), key 4 has no effect.
- Key 5 (SELECT) makes it possible to select one of the panel devices (line or zone etc.) to display the state and carry
out deactivation operations.
Each time it is pressed, the display offers a selection of different categories, with the choice between: selection lines,
selection zones/sectors,
The selection is finished by setting the desired device number and typing in as many characters as there are dashes in
the displayed selection (e.g. 001 for line 1 or 01 for zone/sector 1).
After selection, the display shows the description and state of the device with which, if applicable, it will be possible to
carry out deactivation/activation operations using key 6 (see charter 5).
- Key 6 (DEACT.) only works after selecting a device using key 5 and makes it possible, if applicable, to deactivate or
activate it.
- Key 7 (TEST LED) makes it possible to test all the LED for the panel, buzzer and display.
Keys F1, F2, F3, F4 operate in access level 2 as follows:

3-4 LEDS FOR STATE OF ZONES 1-32
(Ref. fig.1, section 3-1)
There are 3 LED on the panel unit for each of the 32 potential panel zones or sectors for displaying their state as required
by standard UNI EN 54-2.
The 3 LED are only active for the zones which have been configured on the panel (the LED for non-configured zones are
always off and only come on during the LED test) and respectively indicate the states of: FAULT, ALARM and
DEACTIVATION/TEST with the following meanings:
Zone fault yellow LED
When permanently ON, it indicates that the line associated with the zone is in a state of fault (inefficient detector,
corresponding line open/in short circuit, relative concentrator broken or off line).
If it flashes regularly, it indicates that the relative zone is currently in a standby state but previously registered a state of
fault (memorized signal).
The details of the lines which are causing or have caused the fault are visualized on the panel display.
Zone prealarm/alarm red LED
When permanently ON, it indicates that the line associated with the zone is in a state of alarm (state of smoke/fire
present).
If it flashes on for a long time and off briefly, it indicates that there is a state of prealarm in the zone. A state of prealarm is
activated when the established threshold is exceeded on a previously set line without reaching the alarm threshold (e.g.
alarm on an individual sensor on an consumption line.
If the zone prealarm/alarm LED flashes regularly, it indicates that the zone is in a standby state, but previously registered
a state of prealarm or alarm (memorized signal).
The details of the lines which are causing or have caused the prealarm or alarm are visualized on the panel display.
Zone lock or test yellow LED
When permanently ON, it indicates that the relative zone and therefore all the configured in it are deactivated (the panel
ignores alarms/faults in Lines and the zone).
If it flashes on for a long time and off briefly, it indicates that the zone is in TEST phase (the test is also signalled by the
relative general LED coming on and the display).
If it flashes regularly, it indicates that the zone is in the reset phase (temporary deactivation).
The states of deactivation/activation/zone test can be obtained by using the keyboard and display as shown further on.

4- LINE AND ZONE CONTROL, OPERATING FUNCTIONS:
4-1 PANEL LINES AND ZONES; CONTROL LOGIC
The panel can control up to 32 logical zones/sectors to which 1 input lines can be freely associated during the
configuration stage.
ÍNOTE: To meet the requirements set by standard UNI EN 54-2, bear in mind that the total number of or buttons
associated with a zone must not be greater than 32.
The input lines, are physically controlled by two-wire consumption lines.
The panel reads the state of the system lines by communicating with the concentrator modules and receiving the relevant
information from them.
If one or more of the sensor is in a state of alarm or fault, the panel activates the corresponding state on the zones to
which the corresponding line of the detector have been linked.
Finally, based on the state of the zones, the panel controls the activation of the alarm and general fault outputs and the
main displays.

Fig. 3: block diagram for panel acquisition and processing logic.
The panel zones are not controlled directly by an actual input panel but are rather an overall logic of physical lines
established in an arbitrary way during the configuration stage.
It is therefore theoretically possible, even if illogical and against the standard, to create zones which include lines coming
from different input concentrators which are located at distance.
ÍNOTE: It is not possible to link the same line to more than one panel zone.
Each individual panel line, regardless of the zone to which it has been linked, can also be set during the configuration
stage (access level 3) independently, on the basis of the type and logic of control it is to be submitted to.
To be precise, each individual line can be configured as follows:
- Delayable fire/gas: general fire detector, does not control the prealarm threshold and if the panel delay is on, it
activates the general alarm with the delay function.
- Instantaneous fire/gas: general fire detector, does not control the prealarm threshold and always activates the
general alarm immediately. Typical configuration for manual alarm buttons.
- Fire/gas with prealarm threshold: general fire or gas detector, controls prealarm threshold, and if the delay is on, it
activates the general alarm with the delay function. Typical configuration for gas detectors with 2 thresholds.
- Fire/gas with two prealarm thresholds: general fire or gas detector, controls two prealarm thresholds (only if
compatible with input concentrator module), and if the delay is on, it activates the general alarm with the delay
function.

- Fire/gas with auto-reset of first alarm: general fire or gas detector, does not control the prealarm threshold and is
subject to the auto-reset logic of the first alarm (see paragraph 4-4). Typical configuration for smoke detector in
environments where false alarms are likely.
The zones (logical groups of lines, also defined as “sectors”) can also be configured independently and to be precise can
be set as follows:
- Fire/gas: type of general zone which follows the general panel logic. Typical configuration for fire/gas detectors.
- passive prealarm/alarm: zone on which the prealarms/alarms of the relative lines do not lead to the general relays
and buzzer being activated (unless otherwise set) or memorising, but to the activation of visual signals which remain
for as long as the cause of activation remains. Typical configuration for technological detectors.
- Fire/gas disable by functional block: type of zone which follows the general panel logic but can be deactivated if
the corresponding programmable logic is on. Typical configuration for fire/gas detectors which must be periodically
deactivated, for example in time bands.
- passive prealarm/alarm disable by functional block: behaves like the “passive prealarm/alarm” zone type, but can
be deactivated if the corresponding programmable logic is on. Typical configuration for technological detectors which
must be periodically deactivated, for example in time bands.

4-2 PREALARM, ALARM AND FAULT:
The ALPHA 16 - 248 panel monitors and signals three panel states: PREALARM, ALARM, FAULT.
PREALARM:
It is activated if a reading is picked up by a detector configured to monitor this state.
For example the prealarm can be activated by:
- exceeding the first threshold on a gas detector.
- alarm on one detector on an consumption line.
ÍNOTE: If one of the indicated conditions occurs on a line which is not configured for prealarm control, the alarm is
activated directly.
The prealarm, unless configured otherwise, does not activate the general alarm outputs but only sets off an acoustic
signal, a special flashing of the LED for the corresponding zone (on for a long time, briefly off) and the display of the line
which caused the signal.
The panel does not have a physical output dedicated to prealarm, but it is possible to associate one of the programmable
outputs with it.
In the configuration stage (access level 3), it is possible to set the panel so that the alarm delay count (if applicable)
comes on following a prealarm, at the end of which the general outputs are activated.
ÍNOTE: If the zone associated with the line which caused the prealarm has been configured as “passive”, the
signals and general prealarm/alarm outputs are not activated.
ALARM:
It is activated if a reading is detected by one or more lines and triggers the activation of the general outputs (if not
deactivated by relative command) and specific signals. To be precise, the panel buzzer comes on, the corresponding
zone LED is ON permanently and the general alarm LED is ON.
If the detector has been configured as “delayable” and the general delay function is on, the alarm outputs are not
activated immediately but follow the period set.
ÍNOTE: If the zone associated with the which caused the alarm has been configured as “passive”, the signals and
general outputs are not activated and only information relating to the detector and zone is displayed.
FAULT:
This can originate from different conditions: faults due to lines, faults on communication lines, loss of isolation at earth,
broken fuse, malfunction of a power supply panel, malfunction caused by interference, electrical problems in panel
components.
The different types of fault are shown by corresponding yellow LED coming on and specific messages which appear on
the display. The faults which directly relate to a line (e.g. short circuit of an consumption detection line) lead to the fault
LED being ON for the zone to which the detector is associated.
In the event of a fault, the panel buzzer, general signalling and relevant output are also activated (if not deactivated by
specific command).
If the general fault LED is permanently on, it indicates the active presence of a fault, while if it flashes it indicates a
memorized condition (fault no longer present).
4-3 FUNCTION OF DELAYED ALARM:
The panel has a function that puts a delay on the activation of general alarm outputs following an alarm signalled by lines.
ÍNOTE: The alarm delay only applies to general outputs; optical and acoustic signals on the panel unit are activated
immediately.
For the delay function to work, individual lines (not zones/sectors) must be set accordingly during the configuration stage.
The alarm delay LED on the panel unit must also be on, showing the delay function is activated (the delay function can be
activated/deactivated in access level 2 using the relevant ON/OFF key).
The activation of the alarm delay time is indicated by the general alarm LED flashing. It is ON permanently as soon as the
count finishes and the outputs are activated.
During the alarm delay stage it is possible to stop the function and instantly activate the outputs by pressing the
Immediate alarm key.
ÍNOTE: Pressing the immediate alarm key in access level 2 when the prealarm/alarm outputs are stopped, the latter
are immediately reset.

Index : A
Date : 26/03/07
Page : 20/49
ÍNOTE: Alarms originating from lines configured as instant do not trigger the alarm delay count but immediately
generate the activation of the outputs.
4-4 FUNCTION OF FIRST ALARM AUTO-RESET:
At the configuration stage it is possible to set the lines for the function of auto-reset of the first alarm.
Auto-reset of the first alarm is a filter function which makes it possible to ignore suspect alarm conditions.
The auto-reset logic is as follows:
a) If an alarm condition is detected by a detector on a line set for auto-reset, it does not trigger the alarm in the
corresponding zone but activates an internal delay of 3 seconds.
b) If an alarm condition is detected in this period by another detector, it is recognised by the panel as true (AND of two
alarms generate the true alarm).
On the contrary, at the end of the 3 seconds, the panel activates the auto-reset of the lines for a few seconds (reset
time programmed during configuration), thus allowing the physical reset of the line which caused the starting condition.
ÍNOTE: The auto-reset does not cancel any signals of alarm/fault previously memorized on the panel LED and
display, but in any case intervenes at a global level, temporarily removing the power supply from all panel
consumption lines to allow the physical reset.
c) After the auto-reset time, the panel starts a 5-minute internal count.
If another state of alarm occurs during this time on any line (including the one which caused the starting condition), the
panel triggers a true alarm and starts the 5-minute internal count again. On the contrary, at the end of this period, the
alarm filter function is reset as in point a).
4-5 TEST ZONE FUNCTION:
The TEST function makes it possible to try out the system without activating the alarm actuators.
On the ALPHA 16 - 248 panel, the test can also be activated for individual zones, as required by UNI EN54-2.
To activate/deactivate the test function press the ON/OFF button beside the ‘Test enabled’ LED when in access level 2
(the test mode state is indicated by the LED coming on and a message on the display). The individual zones to be tested
(see section 5-7) must then be selected using the numerical keyboard and display and confirmed with key 9. If key 9 is
pressed without selecting a zone, the test is activated globally across all zones.
The zones are being tested when the yellow LOCK/TEST LED flash on and off (the on time is longer than off time).
All alarms originating from lines which are controlled by zones selected for testing are treated by the panel with the
following logic:
a) The panel buzzer is activated.
b) Each alarm is signalled on the display and memorized on the relative zone LED.
c) A few seconds after an alarm is activated, the panel carries out an automatic reset of the detector lines without deleting
the memory on the LED/display.
ÍNOTE: The zones not selected for testing remain fully operational and in the event of an alarm activate the relative
signalling/command components (sounders).
The test function deactivates automatically after 30 minutes if no command operations are carried out, or can be instantly
deactivated by pressing the ON/OFF button again located next to the Test enabled LED.
ÍNOTE: While the test function is on, access level 2 also remains on.
5- COMMAND FUNCTIONS:
5-1 OPERATING LEVELS AND 2nd ACCESS LEVEL ACTIVATION:
As provided for by standard UNI EN 54-2, the panel controls several operating levels for carrying out command and
configuration operations.
The operating levels follows:
- Level 1 (commands not enabled):
The most basic operating level, always ready and intended for the public or those who have general surveillance duties.
