SICURGAS PLACEMENT
EXAMPLES OF CONNECTION
ELECTRICAL CONNECTIONS
Sicurgas P11 must be fixed on the wall, about 30
cm from the ceiling and at a distance from gas
user device, between a minimum of 1 meter and a
maximum of 4 meters, in such position as to allow
natural air circulation.
Sicurgas P12 must be installed approximately 2
meters (minimum 1m maximum 4m) from the gas
user device and about 30 cm from the floor.
Sicurgas P11 is already equipped with two internal
alarms: one visible and one acoustic.
Just connect the line 230V c.a. 50Hz to the
terminals 4 and 5 to ensure the gas presence
signaling in the environment.
It is recommended to use a valve with manual
reset to stop the gas supply when there is an alarm
situation.
The internal relay can control all kind of power
supplied valves with manual reset:
normally closed (NC), always power supplied,
which require a commutating stable relay;
normally opened (NO), which require an
impulse relay.
Example of connection with stable relay, always
power supplied, to control a normally closed valve
with manual reset (down switch).
The system guarantees maximum safety, the gas
inflow will be stopped in case of:
gas concentration threshold exceeding;
power supply lack of the valve only or of the
detector;
connection breakdown between the detector
and the valve.
For device power supply, connect
the terminals 4 - 5 to the circuit
230V-50Hz.
Relay operating mode can be chose in the
installation moment, by moving a switch (JP6) on
the printed circuit, normally supplied for functioning
with stable relay for NC valves (down switch).

ATTENTION!
DO NOT place the device behind or under
cabinets or shelves that are not allowing the
natural air circulation in environment.
DO NOT place it near aerators (minimum distance 2
meters).
DO NOT place it on the vertical bakery surfaces,
steam sources, in places where can be achieved by
splashing water, near sinks, etc.
DO NOT place where environmental conditions are
different from the prescribed operation conditions.
