Sicurgas P71-P72
Flush mounting gas leak detectors for methane and LPG,
for civil environments
Sicurgas is a device that through a sensitive sensor, detects methane gas concentration (P71) and LPG concentration
(P72) in civil environments.

Power supply: 230Vac - 50Hz.
Consumption: 3 VA.
Output through electromagnetic relays.
Contacts rating: 5(3)A - 250Vac.
STANDARDS AND APPROVALS
Complies with EN 60730-1 standards

INSTALLATION
Flush mounting in 3-module 503 embedded boxes by means of 2 screws (supplied).
METHANE is a gas lighter than air, the maximum concentration
is located near the ceiling.
Install the unit on the wall, about 30 cm from the ceiling and at a
distance from gas using device, between a minimum of 1 meter
and a maximum of 4 meters.
LPG is a gas heavier than air; the maximum concentration is
located near the floor.
Install the unit approximately 2 meters (minimum 1m, maximum
4m) from the gas using device and about 30 cm from the floor.
OPERATION
Sicurgas operates when the gas concentration in the air is much under the lower explosion limit (L.E.L.), immediately turning on the
red light.
In case of alarm, interferes as well an acoustic alarm that is going to prevent the danger. Simultaneously Sicurgas is making the relay
to interfere in order to control the gas interception valve.
Sicurgas has three warning lights:
green LED - indicates that the detector works properly;
yellow LED - indicates detector failure;
red LED - indicates the gas presence in the environment (ALARM).
The detector controls, through a relay, the normally closed (NC) and normally open (NO) valves with manual reset.
Sicurgas sensor, as all available on the market sensors, while being very selective can also participate for other substances, for
example: alcohol vapors, wine etc.
For example, during the use of wine while preparing food is possible, that the detector will enter in alarm situation. To avoid this
inconvenience, Sicurgas is equipped with an alarm silencing key (P61AE excluded), operated with:
pull cord for Sicurgas P71 for methane gas (mounted up on the wall, 30 cm from ceiling);
key under Sicurgas P72 body for LPG (mounted down on the wall, 30 cm from the floor).
N.B. silencing key must be pressed for at least 1 second.

TECHNICAL FEATURES
Shockproof insulating material casing.
Semiconductor sensor for gas detection.
Sicurgas has three warning lights:
green LED - indicates that the detector works properly;
yellow LED - indicates detector failure;
red LED - indicates the gas presence in the environment (ALARM).
The used relay is sealed and filled with inert gas, which ensures in any case the absolute absence of sparks during switching phases.

EXAMPLE OF CONNECTION of Sicurgas P71-P72 with STABLE RELAY, to control a
normally closed NC valve with manual reset.
With normally closed valves, always power supplied, the system guarantees
maximum safety, the gas inflow will be interrupted in case of:
gas concentration threshold exceeding;
power supply lack of the valve only or of the detector;
connection breakdown between the detector and valve.
EXAMPLE OF CONNECTION of Sicurgas P71-P72 for controlling a normally open
NO valve with manual reset.
With normally open valves, the system guarantees the gas inflow interruption in case of:
gas concentration threshold exceeding.
After having pressed the silencing key, for 10 minutes we will have a non-alarm situation: the buzzer does not emits acoustic signaling,
the relay returns in non-alarm position and the red and yellow leds are flashing alternately to indicate the silence period; acting again
on the switch during 10 minutes of the silence period, the detector will immediately resume the normal operation.
After 10 minutes, the detector automatically resumes the normal operation.
Here is possible, knowing that can be used substances which can cause a false alarm, to reduce in advance detector’s sound to
prevent the signalizations and gas shut off of the stoves (due to gas valve intervention).
SOME OF THE MOST COMMON SUBSTANCES THAT CAN CAUSE A FALSE ALARM ARE THE FOLLOWING:
wine, liquors, alcohol, deodorants, stain-removers, varnish thinners, hair spray, excessive steam.
