1) Apply power using the proper switch. This switch should be fitted with protection fuses.
2) You will notice that some LEDs will light up in turn for about 20 seconds, so as to test the LEDs.
3) The COUNTDOWN begins that lasts about 90 seconds (warm up) afer this the unit is ready to detect.
4) By pressing the MANUAL TEST button, you get the simulation of a gas leak and the unit carries out the
following:

a) The Pre-alarm LED lights up calibrated to 13% LEL or 200 ppm (referred to CO) switching the relay the
buzzer will issue a low frequency sound

b) The Main alarm 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 hight frequency sound

5) To complete the general test, issue gas from a pre-calibrated aerosol

6)  If  you  want  to  simulate  a  zone  fault,  you  only  need  to  disconnect  the  return  cable  of  the  corresponding
probe.
-lights  up  the  flashing  LED  and  FAULT  led  of  the  MAIN  ALARM  led;
-the  buzzer  emits  a  continuous  sound;
-the  fault  relay  and  the  main  alarm  relay  will  switch.
Reconnect the return cable and press the RESET button to restore the functioning of the control unit.

If other problems arise, a specialised and/or authorised technician and/or the Distributor of BEINAT S.r.l.
should be contacted directly.

If  the  device  does  not  start  up.
Check  that  the  230/240V  mains  power  is  correctly  connected.  If  powered  by  the  battery,  check  that  the  12Vdc
power  is  correctly  connected.
If  the  Fault  LED  lights  up.
Check  that  the  connecting  cables  from  the  BX150  to  the  probes  are  intact,  that  the  probes  are  properly
powered,    and  that  the  signal  cable  is  correctly  connected.

If  the  Over  Load  Probe  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.
If  the  Over  Load  Battery  LED  lights  up.
Check  that  the  connection  cables  are  not  short-circuited,  that  the  polarity  has  not  been  inverted,  or  that  the
battery  is  not  damaged
If  the  Control  Unit  is  repeatedly  issuing  an  alarm.
Check  that  there  are  no  gas  leaks.  If  the  alarm  signal  and  the  FAULT  indicator  light  turn  on  together,  check
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.  All
relays  must  be  free  from  electrical  power.
Check  the  drawing  of  the  connections.
If  a  12Vdc  solenoid  valve,  which  does  not  work  well,  is  connected  to  the  BX150.
Direct  connection  of  12Vdc  solenoid  valves  or  sirens  to  the  BX150  is  not  permitted.  An  external  power  unit
must  always  be  used.  The  BX150  gives  a  max  current  of  50mA.
