______________________________________________________________________________________________ 

Microprocessor  electronic  gas  leak  detection  system  for  heating  rooms.  Central 
unit  UCE13.5  can  control  up  to  three  remote  sensors  (also  for  different  types  of 
gas), and the system can be expanded with the use of one or more EXT6.5. Each 
expander  can  control  up  to  six  additional  remote  sensors.  Dedicated  output  for 
normally closed (delivery condition) or normally open 12V solenoid valve. 230VAC 
power  supply  with  optional  battery  charger  card  UZY-13CB  for  a  12V  back-up 
battery.  Input  for  optional  relay  card  to  drive  auxiliary  devices  as  fans,  lamps  or 
additional  230VAC solenoid valve.  Remote  sensors for the detection of methane, 
LPG and carbon monoxide with tin dioxide semiconductor sensing element. 

______________________________________________________________________________________________ 

The  UCE13.5  Central  Unit,  with  one  or  more  remote  sensors,  is  used  for  optical  and 
acoustical signalling and for command a solenoid valve for shutting the gas flow in case 
of dangerous concentrations of: 

  Methane (CH

4

  LPG 

  Carbon monoxide (CO) 

The  UCE13.5  and  expander  EXT6.5  can  control  simultaneously  different  types  of 
remote sensors for a complete gas monitoring of a heating plant.
