1 - TECHNICAL SPECIFICATIONS
The G 300M control unit has been designed and built according to European regulations to flexibly detect the1A presence of
toxic and/or explosive gas and OXYGEN, through the connection of 3 remote probes.The presence of this and other
devices makes the control unit suitable for Tertiary and Industrial uses. 1 AThe G 300M control unit has three danger levels:
Other technical features make this control unit extremely versatile and reliable; for example, by using a series of
microswitches it is possible to:
In addition to the alarm signal light, it is fitted with an internal buzzer for acoustic signals.
The IP44 external structure was designed for installations on walls, or on electrical panels by means of special brackets.
2) Maintenance TEST. With special arrangements you can enable the function of exclusion of the general alarm relay for a
maximum duration of 60 minutes.
1) System TEST. Pressing the TEST button tests the entire system, including the relays and accessories connected to it.
The presence of a TEST button allows to check the correct functioning of the control unit in two ways:
Response Time ............................................................................................................................................ < 2"

When the microswitch is set to ON, the equipment STORES the alarm occurred by flashing the general alarm LED,
until the RESET button is pressed.
By setting the microswitch to OFF, the equipment DOES NOT MEMORIZE the alarm occurred, and the relay
switches off when the connected probe no longer detects gas; in compliance with the Regulation, this function
becomes active only when the detection of Toxic Gases (reading in "ppm") is selected.

7 - INSTALLATION AND POSITIONING THE 1GA300M CONTROL
The 1GA300M control unit belongs to group II and must be installed in a safe area;
Outside the ATEX zone, however, not in boiler rooms or engine room.
The control unit must be accessible and visible to the user.
The 1GA300M is designed so that it can be mounted externally or built into electrical panels.
The Control Unit complete cabinet is an equipment suitable for wall mounting and is powered by 110/240 VAC with
IP44 protection.
When installing, it is good to use the normal care that an electronic equipment requires:
- Install the equipment away from excessive heat sources.
- Avoid liquids coming into contact with the control unit, remembering that its external structure has IP20 degree of
protection if installed on the Boxed version (cabinet) supplied to the source is IP44.
- in order to detect160 cm from the lowest point of the floor volatile gases CO( , etc.)
- in order to detect30 cm from the highest point of the ceiling ( , etc.)light gases Methane
- in order to detect30 cm from the lowest point of the floor heavy gases L.P.G.( etc.)
You can connect many types of remote probes to this unit. Therefore, they should be positioned at different heights
depending on the type of gas to be detected.
These heights are:
The Sensor must be selected with an IP degree depending on the area to be controlled (Kitchens, Boiler
Rooms, Laboratory, etc.) by selecting one of the probes from Perry (see page 3).
8 - INSTALLATION AND POSITIONING OF THE SENSORS ()PROBES
It is important to note that the remote probes should be installed according to the following restrictions:
- At least once a year make a more accurate check by a specialist technician.
- The probes being taken out of service after 5 years from installation must be carried out by qualified personnel.
The user periodically (every 6 months) must perform a check of the operation of the control unit by spraying a suitable test gas at the base
of the probes connected until the alarm condition is reached.
N.B.: the internal GAS sensors of the probe are perishable components with a variable average life span from 5 to 6 years (you can request
the relative table). Therefore, after this period of time has elapsed it is advisable to replace them.
1) should not beThe probes placed near the appliances to be controlled (boilers, burners, industrial kitchens, etc.) but on the opposite side.
2) should not beThe probes affected by smoke, vapour, and moving air, as they could distort their measurement.
3) should not beThe probes placed near sources of heat, ventilators or fans.

1) Apply power using the proper switch. This switch should be fitted with protection fuses.
2) You will notice that some LED will light up in turn for about 20 seconds, so as to test the LED.

3) The Led ON continues to blink about 1,30 minutes after which remains steady light.
This indicates that the control unit is ready to detect.
4) By pressing the TEST button, you get the simulation of a gas leak and the unit carries out the following:
a) 1st Pre-alarmThe LED lights up calibrated to 8% LEL or 120 ppm (referred to CO) switching the reference relay.
The LED lights up calibrated to 13% LEL or 200 ppm (referred to CO) switching the reference relay;b) 2nd Pre-alarm
the buzzer will issue a low frequency sound.
c) Main alarmThe LED lights up calibrated to 20% LEL or 300 ppm (referred to CO) switching the relay.
The Main alarm LED starts flashing; the buzzer will issue a high frequency sound.
When releasing the TEST button, you will see the opposite: only the LEDs of the MAIN ALARM relay will be
illuminated in flashing mode and the leds of 20% of the L.I.E.
The main alarm will persist as long as you do not press the RESET button, so canceling the alarm memory.
5) To complete the test please read the manual of the probe and perform sensor test by emitting gas with a pre
calibrated bottle.
Troubleshooting and solutions before calling a technician
Check that the 230VAC mains power is correctly connected.
- If the device does not start up
Check that at the terminals 3 and 5- (6-7) is present a voltage from a minimum of 0,8 VDC at a maximum of 1,1 VDC
Check that the voltage at the terminals 3-4, is greater than 11 VDC and less than 25 VDC
- If the Over Load Probe LED lights up
- If the Over Load Battery LED lights up
Check: that the power polarity has not been inverted, that no short-circuit is present, that the probes were not damaged
during installation, that no excessive current absorption is present.
Check that there are no gas leaks.
Check that the probe cables are connected as in the drawing, they have not pinched the insulating sheath
- If the Fault LED lights up
Check that together with the alarm signal is not also turn on the FAULT indicator, in this case, control the probes.
- If the Control Unit is issuing an alarm and does not shut off the devices connected to it
Check that the wiring is correct and that the jumper that carries power to the relay has been set properly.
If powered by the battery, check that the 12Vdc power is correctly connected.
If other problems arise, a specialised and/or authorised technician.
The control unit gives a max current of . Check the drawing of the connection diagram.100mA
Direct connection of 12VDC solenoid valves or sirens to the control unit is not possible, having absorption in excess of
100mA. To connect a solenoid valve with superior absorption you must resort of an external battery.
- If a 12VDC solenoid valve is connected and does not work well
NOTE: all relays are voltage free; check the connection drawing.
- If the Control Unit is repeatedly issuing an alarm
Check that the connection cables are not short-circuited, that the polarity has not been inverted, or that the battery is not
damaged.

WARNING! Actions to be taken in case of alarm
If the alarm continues and the cause of gas presence cannot be found or removed, abandon the building and
call the emergency services when outside (fire department, distributors, etc.)
Close the main gas tap (CH4) or the LPG cylinder tap.
If the alarm stops, its cause must be found and the relevant consequent measures taken.
If you have the following symptoms: vomiting, sleepiness, or else, go to the closest first aid station and inform
the operators that you could have been poisoned by Carbon Monoxide, or by an excess or deficiency of
oxygen
Do not turn any lights on or off; do not turn on any electrical device or appliance.
Open windows and doors in order to increase ventilation.
Put out all free flames.
