ELECTRICAL CONNECTION: POWER SUPPLY
Attention: undertrack cables are required to connect the instrument to the mains.
The gas detector must be powered at 230Vac 50/60Hz using terminals 1 and
2, or at 12Vdc using terminals 3 (+) and 4 (-). (Fig. 2).
A circuit breaker must be fitted that is able to disconnect the detector from the
power supply, with a contact distance of at least 3 mm, in accordance with the
European standard IEC EN 60335-1.
INSTALLING THE INSTRUMENT
The instrument MUST BE INSTALLED:
- In the case of
Beta
SE330KM and
Beta
SE333KM methane gas detectors,
CHARACTERISTICS OF THE OUTPUT SIGNAL
The
Beta
SE330K and SE333K control units have an output relay with voltage-
free contacts; the rating of the contacts is 8A 250Vac/30Vdc.
LIGHTING DELAYS
After the detector is turned on, the catalytic sensor in the detector takes about a
minute to warm up, during which time the green LED blinks to indicate the alarm
is disabled.
INSTALLATION
Attention: the instrument must be installed and put out of service by a specialized
technician.
Your gas supply and any shut-off devices must be installed in conformity with the
domestic laws in force.

GENERAL DESCRIPTION
The
Beta
SE330K and SE333K gas detectors are methane or LPG control units
with LEDs and a buzzer that warn of the presence of gas in the room. They are
designed to be operated either directly or in remote mode.
The
Beta
detectors are calibrated to detect gas at 10% of the LEL (Lower Explosive
Limit); this threshold can vary according to environmental conditions but will not
exceed 15% of the LEL within the first five years of use.
After such a period
or in case of lighting of the LED “FAULT”, the
Interchangeable Sensor
has to be replaced.
With that aim, the package is provided with a printer label on which have to be
indicated the maturity of correct working period (5 years from installing date);
this printer label have to be filled by who makes the installation.
LEDS AND BUZZER
There are three LEDs on the front of each detector:
- GREEN LED (ON): indicates the instrument is powered.
- YELLOW LED (FAULT) + BUZZER: Indicates the sensor is broken.
- YELLOW LED (FAULT) blinking only: indicates the CO sensor
needs to be replaced.
- RED LED (ALARM): indicates the concentration of gas in the
air is above the alarm threshold.
If the gas sensor is defective, the buzzer will make a noise at a rate of every two
seconds, turning on the yellow LED and relay output.
In the event of an alarm, the red LED turns on and the buzzer and relay are
activated twenty seconds later.
INSTALLATION INSTRUCTIONS
Use a screwdriver to undo the screw on the right-hand side of the instrument and
lift the cover (Fig 1).
Position the base correctly and fasten it on the built-in 3-module box or on the
wall, using the screws and dowels provided. For installing the dowels drilling
the wall with a 5mm drill.

at a maximum distance of 30 cm from the ceiling; in the case of

SE330KG
and
Beta
SE333KG LPG gas detectors, at a maximum height of 30 cm above
the floor.
- At a distance of between 1 and 4 metres from the gas appliance (cooker, boiler,
etc.). If possible, in every room where there is a gas appliance and, in the case of
multi-storey buildings, at least one on each floor.
The instrument MUST NOT BE INSTALLED:
- Directly above the sink or gas appliance.
- In small rooms where alcohol, ammonia, spray cylinders or other substances
based on volatile solvents might be used.
- In closed environments or corners where there is no free circulation of air.
- Near walls or other obstacles that could prevent the flow of gas from the appliance
to the detector, or extractors and fans that could divert the flow of air.
- In environments where the temperature could exceed 40°C or fall below – 5°C.
- In environments where there is a high level of humidity or steam.

CONNECTION OF THE ELECTRIC VALVE AND REMOTE SENSORS
The
Beta
SE330K and SE333K control units each have two terminals (5-6) active
when closed, for connecting the following remote detectors (Fig. 3):
for METHANE gas: model SE195KM or model SE396KM.
for LPG gas: model SE195KG or model SE306KG.
If the remote sensors are not connected to terminals 5 and 6, these must not be
modified, and therefore kept disconnected at all times.
Do not forget that the electric valve must be installed on the gas pipe outside the
room to be controlled as it cannot protect against leaks upstream.
The
Beta
SE330K/
Beta
SE330K/SE333K configuration is IMQ
certified.
The other configurations,
Beta
SE330K/ SE195K and
Beta
SE330/
SE396K are not IMQ certified.
