Important Note

Before  connecting  the  unit  careful  reading  of  instruction  booklet  is  recommended,  and  it  is  kept
in  a  safe  place  for  future  reference.
Furthermore,  the  correct  electrical  connections  according  to  the  enclosed  drawings,  complying
with  instructions  and  Regulations  in  force,  is  recommended.

 Belonging  to

GS920
          Gas Detector with Earthquake-proof Device

The GS920, thanks to its innovative 

Seismic Detection

” feature and the possibility

of  selecting  the  “Intrinsic  Safety  Control”,  is  a  leading-edge  technological  device.
A  microprocessor  was  used  to  create  a  complete  surveillance  and  control  system
with  maximum  flexibility.
Together  with  its  catalytic  sensor  technology,  it  detects  the  presence  of  explosive
gas,  such  as:  Methane  and  LPG,  with  trip  threshold  calibrated  at  10%  of  Lower
Explosion  Limit.
Using  the  built-in  relay  it  can  activate:  solenoid  valves,  sirens,  and  any  other  alarm
signal  device.  The  micro  switch  makes  it  possible  to  select  the  relay  impulse
functioning,  to  connect  manual  reset  solenoid  valves,  or  the  continuous  functioning,
and  to  activate  N.C.  class  “A”  solenoid  valves  and  sirens.
Another  micro  switch  allows  turning  on/off  the  “

Intrinsic  Safety

”.

The  power  supply  unit  allows  driving  of  a  manual  reset  solenoid  valve  with  a  12Vdc
coil,  without  any  buffer  battery.  If  the  voltage  absorption  is  too  high,  you  can  later
integrate  a  suitable  backup  battery.  The  battery  is  recharged  automatically.
The  

Seismic  Control

  allows  closure  of  the  solenoid  valve,  stopping  the  gas

original  source!  This  control  is  vital  in  seismic  regions!  The  relay,  free  of  voltage,
allows  installation  of  multiple  detectors  on  a  single  solenoid  valve,  providing  control
of  multiple  dangerous  environments.
The  technical  scheme  is  completed  by  a  circuit  that  controls  the  catalytic  sensor
“efficiency  level”,  and  signals  any  possible  fault.
These  technical  features  make  the  detector  ideal  for  civil  environment  safety
according  to  EUROPEAN  REGULATIONS.
