BEINAT GS300-Mc Instruction Manual

Control Unit from 1 to 3 Conventional sensors GS300-Mc
The GS300-Mc control unit has been designed and built according to European regulations to flexibly detect the
presence of toxic and/or explosive gas and OXYGEN, through the connection of 3 remote probes.
A microprocessor is used to create a complete surveillance and control system with maximum flexibility. Thanks to this
and its other features GS300-Mc is suitable for civil use, industrial use and small underground car parks.
The GS300-Mc control unit has three danger levels:
st st
1 LEVEL, 1 Alarm. This was set to 8 % of L.E.L. (120ppm)
nd nd
2 LEVEL, 2 Alarm. This was set at 13% of L.E.L. (200ppm)
rd
3 LEVEL, Main Alarm. This was set at 20 % of L.E.L. (300ppm)
For oxygen the centrol unit GS300-Mc presents three levels of danger which are:
1st Pre-Alarm. Both in deficiency and excess of Oxygen.
2nd Pre-alarm. Both in deficiency and excess of Oxygen.
Main alarm. Both in deficiency and excess.
To facilitate event readings, the control unit has a front panel with 4 LEDs indicating which probe is currently being
monitored in rotation, and a display showing the gas concentration measured.
Other technical features make this control unit extremely versatile and reliable; for example, by using a series of micro-
switches it is possible to:
Select or disable the probe when not installed or faulty;
Select the type of gas to be detected (toxic or explosive);
Choose the relay functioning mode (pulsed or continuous);
Choose to enable or disable of the intrinsic safety.
The GS300-Mc has the prerequisite to be able to test "TEST" in two different ways:
1) System Test TEST. Pressing the TEST button tests the entire system, including the relays and accessories connected
to it.
2) Maintenance TEST. With special arrangements (see page 8) you can enable the function of:
Exclusion of the general alarm relay for a maximum duration of 60 minutes.
The IP44 external structure was designed for installations on walls, or on electrical panels by means of special brackets.
In addition to the alarm signal light, it is fitted with an internal buzzer.
Important: Assembly / maintenance of the appliance must be carried out by qualified personnel and in
accordance with applicable laws and regulations.
The manufacturer assumes no responsibility for the use of products that have to comply with particular
environmental and / or installation standards.
