INSTALLATION
P30A GENERAL CONTROL PANEL INSTALLATION
Screw the xing stay-bar and release the control panel
socket . Remove the socket by pulling with a
screwdriver on the latching tabs.
Fix the terminal-holders of the wall detector (according
to the xing systems shown hereby) in a dry not
dripping place.
SENSORS DETECTORS
They shuold be xed on a wall at an approximate
distance of 2 meters form the gas device in such a
position as to allow natural air circulation:
-S71 for specic ligth gases (natural gas, city gas) has
to be xed at an high level approximately 30/40 cm
from the ceiling.
-S72 for heavy gases (cylinder liquid gas LGP) has to
be xed to a low level approximately 30/40 cm above
the oor.
Avoid installing sensors:
-behind barriers that can prevent the natural air
circulation in the area
-close to air conditiong units (minimum distance 2
meters)
-close to fumes, steams or other exhalation sources
Remove the cover four front retaining screws, x the
base to the wall, using for the cables entrance the
special press-.cables.
GAS DETECTOR VALVE
Choose the gas interception valve among one of the
serie Z-EV, generally closed with quick on and o
realease switch, class A with approval (or
corresponding models) according to diameter and gas
pipe type.
Install the valve in the most suitable part of the plant
downstream the counter or at the exit of the
accumulation tanks.
ACOUSTIC/VISUAL EXTERNAL SIGNALLER
Use the self-fed type most suitable with your kind of
plant, place it in an easely visibles place.
CONNECTIONS WITH POSSIBLE FIRE ALARM

DEVICE.
The voltage free terminal exchange contact available
for the external acoustic/visual signaller can in
alternative be used for connections with alredy exiting
central alarm panels.
CONTROL PANEL
CENTRAL CONTROL CONSOLE
Visual indicator: normally switched off, flashes in case
of alarm. It can be switched off only through the reset
button.
Operating indicator: always switched on.
Alarm sensors indicators: generally switched off they
switch on when the connected sensor send an alarm
signal. They switch off when the gas concentration
goes back to the allowed levels.
Test switcher to verify the device except for the
sensors.
Switch for external siren silencing: it allows to switch
off the siren even during an alarm situation.
Reset switch to stop the alarm after the cause has
been removed.
Operation delay: unique for all sensors, regulates the
delay once that a warning situation has been detected
by all sensors and it has activated the general alarm.
Acoustic signaller: positioned inside the central
control panel operates in case of alarm. It can be
switched off only through the reset switch.
SENSOR
Operating indicator: always switched on.
Fault indicator sensor
Alarm indicator: generally switched off, it operates
and remains on for all the time in which the gas
concentration remains above the established level.

GENERAL FEATURES
The industrial environment electronic central gas leak
detector P30A equipped with specic sensors (S71
for natural gas and S72 for LPG) is ideal for
controlling and signalling dangerous gas
concentration in the air specifically for detecting
natural gas, city gas and LPG (Cylinder Gas)
excesses.
When in the controlled area there is a gas
concetration that exceeds the established level the
device triggers on the electrovalve to stop the gas
inflow. At the same time a an simultaneously visually
and acoustically signaling the danger. In addition to
the internal alarm system an external siren can also
be controlled . It is evident that the established level
control is much more inferior to the danger threshold
to allow the necessary time to operate before the
exhalation of a gas-air explosive or toxic mix
becomes dangerous for a human being.
Even three sensors, of different kind, can be
connected to the same detector to control different
areas or to control different kind of gases..In case of
gas leaks a luminous led on the control panel will
indicate the interested area.
The alarm can be delayed on the central panel up to
approximately one minute to avoid fortuitously
operating and the gas interception valve
TECHNICAL FEATURES
-Box and socket of insultated material, transparent
cover. Protection degree IP 40 .
-Installation possibilities: embedded, projected or
behind the control console.
-Overall dimensions according to DIN 43700;
144x144mm.
-Voltage 230 V c.a.- 50 Hz or 12 Vcc.
-Consumption 5VA
-Outlet through electromagnetic relays on volt free
terminals radio noises protected with RC group
(according to D.M. 9/10/1980).
-Contacts Carrying Capacity: 5A - 250 V AC-1.
-Alarm delay regulation up to one minute.
-Working environment temperature: -10• to +50•.
INTERNAL ALARMS
-Instantaneuos: visual with area indication (Red
Led)
-Delayed: acoustic and visual.
EXTERNAL ALARMS
Two relays with changeover volt free contacts are
available:
-one to operate interception valves
-one to operate an external electric horn
(disconnectable).
DETECTORS SENSORS
The operation sensors threshold is set by the
manufacturer at such a level to warn a gas
concentration much lower than the danger limit.
For special applications it is possible to change
the sensitity of the sensor opertating on a specific
way of regulation which, for security reasons, can
not be externally reached.
The detectors sensors are equipped with a
lumious led to signal the need for intevention and
the central panel connections are with positive
security (their interruption causes the detector
operation).
- Anti shock insulating box, protection degree
IP65.
- Green led diode marks the functioning of the
device
- Red led diode marks need for intervention.
- Detector positive security connections.

ELECTRICAL CONNECTIONS
Install a small switch with 1A fusbile
valves on the power supply of the
central console in order to protect the
valve and to disconnect the voltage
when removing the central console
from the socket.
The electical connections among
probes and the central console should
be operated with bifilar wires with a
maximum section of 1mm2 for a
maximum lenght of 200 meters; for
bigger distances the section of the wire
has to be increased proportionally in
order that the overall resistence of the
wire remains unchanged.
Avoid to pass the probes connections
close to high voltage supply cables.
Connect the various devices according
to the scheme on the side figure.
Make sure that the connections are
well kept and not oxidized.
Plug in the Faston central consol
connecctions in the socket special
terminal-holders by pressing till
complete bedding.
Tighly screw the fixing stay-bar.
OPERATION TEST
Connect to 230 Vc.a. and/or 12Vcc).
On first switing on and after a long period of lack of
power supply on both votages the central control
panel and the sensors get into the alarm situation.
When all three Led C turn off (after a maximum of
20 sec.), push the reset button - Bring the F
operation delay switch to the minimum, the G
switch E on position "ON" and press the "TEST"
button D for a few seconds;
Verify:
- fastening of the valves
- operation of the siren and the possibility of its
silencing through switch E
- Correct functioning of local visual signaller and A
acoustic signaller H.
At the end ot the test press button to restablish F
non-alarm conditions.
To verify sensors correct funtioning:
- switch the delay switch to the maximum levelG
- Bring a lighter near the sensor and let the gas flow
out from it. The local red led and the corresponding
one on the central panel should turn on. C
Repeat the operation for each of the installed
sensors.
It is advisable to repeat this operation
approximately every month to verify the constant
regular functioning of the sensors.
PLANT LAYING
It is advisable after having ended all testing
operation to keep initially under control the
sensitity of each single sensor setting them on a M
central position and the setting the delay operation
G almost at the minimum level.
Adaptations to the controlled areas specific
charateristcs will be made accordingly with the
presence of specific alarm situations or by
reproducing them in real operating conditions.
NB. The detector P30A is provided with
semiconductor sensitive probes. After long non-
operating periods (storage, not-power suppied
device) a stabilisation period is required; the
manufacturer setting keeps that into account
therefore the ideal functioning will be reached after
an initial period of 10 days not-interrupted power
supply.
NB.
-The socket is supplied with two resistences connected
between terminals 12-22 and 14-16 which should be removed
in case they are connected with probes 2 and 3.
-The 12 voltage supply is optional.
