1WALL FIXING
Sicurgas P21 and P22 is a device that through
a sensitive sensor, detects natural gas
concentration (P21) and LPG concentration
(P22) in domestic environments. Sicurgas P21
and P22 triggers a PRE-ALARM when the gas
concentration in the air is much lower than
the lower explosive limit (LEL), immediately
switching on a red warning light and activating
a warning device (e.g. modem). If the pre-alarm
condition persists with consequent increase
in gas concentration with respect to the LEL,
Sicurgas goes into ALARM status, adding an
acoustic warning to the light signal.
Sicurgas simultaneously triggers a relay to
command a gas shut-off valve.
The Sicurgas P21 and P22 gas detectors have FAIL-
SAFE operation if connected to a normally closed
(NC) manually reset valve. This means that the gas
shut-off valve closes interrupting the outflow even
in case of a power failure.
For enhanced safety, several Sicurgas detectors
can be used, connected to the same gas shut-off
valve. For example P21 (P22) can be installed in
the room with the boiler and another in the kitchen
to control the stoves.
Sicurgas is supplied with a base suitable for
installation on recessed boxes with 3 modules or
on a round box. Unscrew the base-lid fixing screw
and turn the lid upwards.
Fix the base to the wall (see paragraph 3) or on
the recessed box and insert the connection cables
through the rear slot.
ATTENTION
Installation of the gas detector does
not exempt from complying with all the rules
regarding the features, installation and use
of gas appliances, ventilation of rooms and
exhaust of combustion products described in
EN implementation standards of art. 3 of law
1083/71 and of national legislation in force.
Before installing the appliance, carefully read
this instruction booklet.

DO NOT TAMPER WITH THE APPLIANCE AS
THIS COULD CAUSE ELECTRICAL SHOCKS OR
MALFUNCTIONING
After fixing and connecting the appliance (see paragraph 4), refit the lid on the base, making sure that the
two teeth on the lid perfectly fit in the two upper guides. Retighten the fixing screw and apply the sticker in
the seat indicating the date of replacement.

WHERE TO POSITION SICURGAS
CONNECTION EXAMPLES
ELECTRICAL CONNECTIONS
Sicurgas P21 must be fixed to the wall,
approximately 30 cm from the ceiling and
between 1 and 4 metres from the gas appliance,
at a position which allows air to circulate
naturally.
Sicurgas P22 must be installed approximately 2
metres (minimum 1m, maximum 4m) from the gas
appliance and 30 cm from the ground.
Example of connection with stable relay, always
powered to control a normally closed NC manually
reset valve (jumper down).
The connection provides the maximum safety,
shutting off the gas supply in case of:
the intended gas concentration threshold
being exceeded;
general power failure or only for the valve or
detector;
interrupted connection between detector and
valve.
The operating mode of the relay can be selected
upon installation, by moving a jumper (JP6)
on the printed circuit, normally supplied for
operation with stable relay for NC valves (jumper
down).

Sicurgas P21 already has two internal alarms: one
luminous and one acoustic.
Simply connect the 230Vac 50Hz power line to
terminals 4 and 5 to be able to warn the presence
of gas in the environment.
It is recommended to use a manually reset valve to
shut off the gas supply when an alarm is triggered.
The internal relay can command all types of
manually reset valves powered by the mains
voltage:
normally closed (NC), always powered, which
require a stable switching relay
normally open (NO), current starting, which
require a pulse relay.
ATTENTION!
DO NOT install it behind or below cabinets
or shelves which obstruct the natural air
circulation in the environment.
DO NOT install it near aerators (minimum distance
2 m).
DO NOT install it right above the hob, sources of
steam in places which could be reached by water
sprays, near washbasins, etc.
DO NOT install it in environmental conditions other
than those indicated.

Sicurgas is equipped with a TEST/SILENCING key in order to check the system or to inhibit the alarm. This
key is activated by a cord for P21 natural gas (installed 30 cm from the ceiling) or by a button on the body of
the appliance for P22 LPG (installed 30cm from the floor).
To test the system, press theTEST/SILENCING key for 10 seconds. This activates the control procedure
lasting 30 seconds during which all the system components are checked.
Inhibiting the alarm avoids the unintentional triggering of the detector. In fact like all sensors on the market,
the Sicurgas sensor, though being very selective, can also be triggered by other types of substances, such
as vapours of alcohol, wine, etc.
For example when using wine for cooking, the detector could trigger an alarm. To avoid this problem, press
the TEST/SILENCING key for at least 3 seconds.
After pressing the silencing key, the alarm will not go off for 10 minutes: the buzzer does not ring, the relay

OPERATION
Sicurgas enters a preheating phase and stabilises
the sensor for a maximum of 3 minutes the first
time the detector is switched on and after every
power failure. During this phase, the red and green
LEDs flash alternately indicating that the device is
not ready for gas detection. After this phase, only
the green light will remain on.

TECHNICAL FEATURES
Sicurgas
OPERATION
ATTENTION! in case of alarm:
1. put out all naked flames;
2. close the valve of the gas contactor or of the LPG cylinder;
3. do not switch lights on or off; do not switch on electrically powered appliances or devices;
4. open doors and windows to enhance ventilation of the environment;
5. do not use telephones in the room where gas has been detected.
When the alarm ceases, find the cause which triggered the alarm and act accordingly.
If the alarm continues and the cause of the gas leak cannot be identified or eliminated, abandon the
premises and notify emergency services from outside.
SOME OF THE MOST COMMON SUBSTANCES WHICH CAN TRIGGER A FALSE ALARM:
wine, liquor, alcohol, deodorants, stain removers, paint thinners, hair spray, excessive water steam.
Sicurgas also allows you to set the
type of acoustic alarm, see figure
to the side
7MAINTENANCE AND CLEANING
Pay attention to extreme temperature or humidity values.
The detector must always be on to provide the maximum safety.
Have authorised technicians perform routine, extraordinary maintenance and decommission the
appliance.
Regularly check its correct operation by means of the specific button or a test gas.
OTHER TEST METHODS COULD DAMAGE THE APPLIANCE.
If the catalyst sensor is exposed to gas concentrations higher than the LEL for a few minutes, it could lose
sensitivity.
Clean the appliance using a soft cloth without detergents or solvents.
Type A appliance.
Case in shock-proof insulating material.
Degree of protection IP42.

Consumption 4 VA.
Range of pre-alarm relay contacts 1(1)A 250Vac
Range of alarm relay contacts 6(2)A 250Vac
Maximum power of solenoid valve controlled by alarm

Catalyst sensor for gas detection.
Internal luminous and acoustic alarms.
Volumetric value of triggering threshold:

goes back to the non-alarm position and the red and yellow LEDs flash alternately indicating the silencing
period. If you press the switch again during these 10 minutes, the detector immediately resumes normal
operation.
When the 10 minutes elapse, the detector automatically resumes normal operation.
Therefore when you know that you must use substances which could trigger a false alarm, you may silence
the detector beforehand to avoid alarms and switching off of the gas stove (due to triggering of the gas
shut-off valve).
