GENERAL DESCRIPTION
LEDS AND BUZZER
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
SE396KM or model SE195KM.
- for LPG gas: model
SE396KG or model SE195KG.
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/SE333K
+ (
Beta
SE330K/SE333K
o
SE396K
)
configura-
tion is
IMQ certified.
The other configurations, ( Ex.
Beta
SE330K
/
SE333K
+
SE195K ) are not
IMQ certified however they fully comply with the CEI UNI EN 50194-1: 2009
standard.
The
Beta
SE330K
and
SE333K control units have an output relay with voltage
free contacts; the rating of the contacts is 8A 250Vac/30Vdc.
CHARACTERISTIC OF THE OUTPUT SIGNAL
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 acti-
vated twenty seconds later.
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.
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.
The instrument MUST BE INSTALLED:
- In the case of
Beta
SE330KM and
Beta
SE333KM methane gas detectors,
at a maximum distance of 30 cm from the ceiling; in the case of
Beta
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 does not have to 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 appli-
ance 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.
INSTALLING THE INSTRUMENT
INSTALLATION INSTRUCTIONS
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).
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.
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.
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 install-
ing the dowels drilling the wall with a 5mm
drill.
